Bay Area Rent Control Guide 2026
Berkeley vs San Francisco
Rent Control 2026:
Side-by-Side Comparison
Two of California's most powerful rent ordinances — different rules, different rent caps, different exit costs. Here's exactly what separates them and what every landlord, buyer, and investor needs to know before putting capital at risk.
Berkeley limits annual rent increases to 65% of CPI (typically 1–2%). San Francisco caps at 60% of CPI with a 1% minimum floor. Both cities require just-cause eviction and relocation assistance for no-fault exits. Berkeley's ordinance covers more unit types and is enforced by an elected rent board. San Francisco's structure is more codified with deeper city legal infrastructure. Neither city can cap rents on Costa-Hawkins-exempt units — post-1995 new construction, single-family homes, and condos. For buyers and investors, the real question isn't just which ordinance is stronger — it's how the specific building and tenant profile changes your income ceiling, your exit costs, and your negotiating position.

Bay Area Rental Market: Key Numbers for 2026
Before comparing ordinances, it helps to understand the market these ordinances govern. The Bay Area is one of the most expensive rental markets in the United States — and one of the most legally complex for landlords and buyers.

How Berkeley and San Francisco Rent Control Compare
Both cities have ordinances that go well beyond California's statewide AB 1482 protections. The differences matter enormously for landlords, buyers, and tenants — and for anyone analyzing the income potential of a rental acquisition in the East Bay versus the City.
The comparison comes down to four levers: which units are covered, how much rents can increase each year, what grounds are required to terminate a tenancy, and what it costs to exit the rental market or reclaim a unit for personal use.
Berkeley's ordinance, enacted in 1980, is widely regarded as one of the most tenant-protective in the state. San Francisco's, enacted in 1979, has deeper city enforcement infrastructure and a more complex legal ecosystem surrounding it — reflecting decades of tenant advocacy and landlord litigation. Neither city is "easy" to operate in. Both reward landlords who understand the rules before acquiring.
| Factor | Berkeley | San Francisco |
|---|---|---|
| Ordinance enacted | 1980 (Measure D) | 1979 (Proposition R) |
| Annual rent cap formula | 65% of CPI | 60% of CPI (min 1%) |
| Typical annual increase | 1% to 2% | 1% to 1.6% |
| Building coverage cutoff | Built before January 1, 1980 | Built before June 15, 1979 |
| SFR/condo coverage | No rent cap (Costa-Hawkins); just-cause still applies | No rent cap (Costa-Hawkins); just-cause still applies |
| Just-cause eviction | Required for all covered units; Measure EE extends just-cause to many post-1980 units | Required for all covered units; Admin Code Ch. 37A extends just-cause more broadly |
| Relocation for no-fault | Yes — multi-month formula, adjusts for tenure and protected status | Yes — multi-month formula, amounts tend to be among the highest in the state |
| Vacancy decontrol | Yes (Costa-Hawkins mandated) | Yes (Costa-Hawkins mandated) |
| Enforcement body | Berkeley Rent Stabilization Board (elected) | SF Rent Board (appointed) |

Berkeley's ordinance being "stronger" does not mean San Francisco is easy to operate in. In SF, the legal infrastructure is more robust, tenant legal aid organizations are better-resourced, and penalties for procedural violations can be severe. In both markets, compliance errors are costly. The safest approach is to know the rules before you close — not after.

Coverage Rules: Which Units Are Controlled
The coverage question is where landlords most often get surprised — and where the distinction between rent caps and just-cause protections creates the most confusion. These are two separate legal layers, and understanding both is essential before buying a rental property in either city.
Rent caps limit how much you can increase rent annually. Just-cause protections require a legally valid reason to terminate the tenancy at all. A unit can be exempt from rent caps but still subject to just-cause eviction requirements — a combination that catches new buyers off guard regularly.
- Rent-controlled: rental units in buildings constructed before January 1, 1980 with 2 or more units
- Just-cause only (no cap): single-family homes, condos, and units in post-1980 buildings covered by Measure EE
- Costa-Hawkins exempt from caps: SFRs, condos, post-February 1, 1995 new construction
- Exempt from both: government-subsidized housing (HUD-regulated), units rented for the first time after June 1981, certain nonprofit-owned units
- Owner-occupied small buildings: certain exemptions apply if owner lives on site — confirm with Berkeley Rent Board
- Rent-controlled: rental units in buildings with 2+ units constructed before June 15, 1979
- Just-cause only (no cap): SFRs, some condos (post-conversion), buildings constructed 1979–1995
- Condo complications: condos with tenants in residence at time of conversion may retain rent-control coverage depending on conversion date and tenant status
- Post-1979 new construction: no local rent cap; AB 1482 may apply for buildings over 15 years old
- Exempt from both: government-subsidized units (Section 8 project-based), certain nonprofits, hospitals, schools
The Condo Conversion Question in San Francisco
San Francisco's condo conversion rules are among the most complex in California. A tenant who was living in a unit when it converted to condo ownership may retain rent-control protections that a brand-new buyer might not expect. The conversion date, the tenant's residency date, and whether the conversion was through the lottery or a non-lottery process all affect continued coverage. If you're evaluating an SF condo with a sitting tenant, pull the full conversion history before closing.
TIC Units: A Special Berkeley and SF Case
Tenancy-in-common (TIC) properties — common in San Francisco — are not condos, and TIC interests generally do not trigger condo conversion rules. However, TIC units that were occupied by rent-controlled tenants before the TIC structure was established may still carry those protections. The SF Rent Board has issued guidance on this; verify any TIC with a sitting tenant carefully with qualified counsel before acquiring.
In both Berkeley and San Francisco, just-cause eviction requirements apply to many units that are not subject to rent caps. A Costa-Hawkins-exempt single-family home still requires a valid legal reason to evict in most cases under local ordinance. Buyers frequently underestimate this because they track only the rent cap exemption — but the inability to remove a tenant without cause is often the more significant constraint on a buyer's ability to use or sell the property.

Call NowRent Caps and Annual Increase Formulas
Both cities tie their annual allowable increases to the Consumer Price Index (CPI), but at different multipliers. This creates meaningfully different income ceilings for landlords holding rent-controlled units — and different long-term cap rate trajectories depending on which market you're in.
Berkeley's Formula: 65% of CPI
Berkeley allows annual rent increases of 65% of the change in the Bay Area CPI for All Urban Consumers (CPI-U). When CPI runs at 3%, landlords can raise rents approximately 1.95%. When CPI runs at 4%, the ceiling is about 2.6%. Historically, this has produced increases in the 1% to 2% range in most years. The Berkeley Rent Stabilization Board announces the allowable increase each year, effective July 1. Landlords must serve proper written notice — typically 30 days for increases under 10%, 90 days for increases of 10% or more — before the increase takes effect.
One nuance: Berkeley requires landlords to actually serve a rent increase notice. The right does not automatically transfer to the next lease term. If you miss your annual notice window, you can bank the increase and apply it later — but you must notify the tenant before collecting it. Failure to provide proper notice is a common compliance error that creates retroactive liability.
San Francisco's Formula: 60% of CPI with a 1% Floor
San Francisco allows 60% of CPI with a floor of 1%. In high-inflation years, the floor is irrelevant. In near-zero CPI years, tenants in SF see a 1% increase when Berkeley tenants might see nothing or a very small amount. The SF Rent Board announces the allowable increase effective March 1 each year. For March 2026, the SF Rent Board has set the allowable increase at approximately 1.4% — verify the current figure at sfgov.org/rentboard before issuing any notice.
San Francisco also allows landlords to "bank" unused allowable increases and apply them retroactively, subject to restrictions. If you acquired an SF building where the prior owner never took increases, you may be able to implement multiple years' worth of allowable increases at once — but the process requires proper notice, and tenants have the right to petition the Rent Board if they believe the increase is impermissible.
| CPI Scenario | Berkeley Allowable Increase (65% CPI) | SF Allowable Increase (60% CPI, 1% floor) |
|---|---|---|
| CPI = 0% | 0% | 1.0% (floor applies) |
| CPI = 1% | 0.65% | 1.0% (floor applies) |
| CPI = 2% | 1.30% | 1.20% |
| CPI = 3% | 1.95% | 1.80% |
| CPI = 4% | 2.60% | 2.40% |
| CPI = 5% | 3.25% | 3.00% |
Both cities allow landlords to petition for above-guideline increases to cover certain capital improvements, debt service increases on acquisition financing, and documented operating cost jumps. The petition process requires detailed documentation, formal hearings before the rent board, and board approval. Budget 6 to 12 months for the process and engage qualified property management counsel before filing. Petition approval is not guaranteed, and the burden of proof is on the landlord.
Vacancy Decontrol: The Reset Valve
Costa-Hawkins requires both cities to allow vacancy decontrol — when a tenant voluntarily leaves, the landlord can reset the rent to market rate for the next tenant. This is the primary mechanism landlords use to close the gap between controlled rents and market rents over time. A building with a $1,400/month controlled tenant in a $3,200/month market becomes a much more attractive investment the moment that unit turns over.
But vacancy decontrol only applies to voluntary departures. Evictions — including no-fault evictions — do not trigger vacancy decontrol. If you evict a tenant via Ellis Act and later re-rent, Costa-Hawkins requires the rent to return to the prior controlled level (plus allowable increases) if the unit is re-rented within the restricted period. A purchase and sale transaction does not trigger vacancy decontrol; the new owner inherits the tenant's tenancy at the existing controlled rent.

Just-Cause Eviction: What Grounds Are Required
Both cities require a legally recognized cause to terminate a tenancy for covered units. Grounds fall into two categories: at-fault (the tenant did something that violates the lease or law) and no-fault (the landlord needs the unit for a legitimate reason unrelated to tenant behavior). Understanding the full list of available grounds — and their limitations — is essential for anyone acquiring a tenant-occupied property in either city.
At-Fault Grounds: When the Tenant Has Breached
At-fault grounds are the more straightforward category. They include non-payment of rent, lease violations, nuisance, illegal use of the unit, refusal to sign a new lease on substantially similar terms, subletting in violation of the agreement, and refusal to allow lawful access. For most at-fault grounds, the tenant must first receive a written notice to cure (correct the violation) before an unlawful detainer can proceed. At-fault evictions do not trigger relocation assistance obligations in either city.
No-Fault Grounds: When the Landlord Needs the Unit
No-fault grounds are where landlords face the greatest compliance risk and financial exposure. These include owner or relative move-in (OMI), substantial rehabilitation, condo conversion, Ellis Act withdrawal from the rental market, and demolition. Every no-fault ground triggers relocation assistance obligations, and each carries procedural requirements that — if violated — can result in wrongful eviction liability, tenant reinstatement, and damages that dwarf the cost of doing it correctly the first time.
| Eviction Ground | Berkeley | San Francisco |
|---|---|---|
| Non-payment of rent | Yes (at-fault); 3-day notice to pay or quit | Yes (at-fault); 3-day notice to pay or quit |
| Lease violation | Yes (at-fault); notice to cure, then quit | Yes (at-fault); notice to cure, then quit |
| Nuisance / illegal use | Yes (at-fault) | Yes (at-fault) |
| Unauthorized subletting | Yes (at-fault) | Yes (at-fault); SF has nuanced rules around roommate additions |
| Owner / relative move-in | Yes (no-fault); relocation required; cannot OMI protected tenants | Yes (no-fault); relocation required; extensive protected class restrictions |
| Substantial rehabilitation | Yes (no-fault); relocation required; right to return at controlled rent | Yes (no-fault); relocation required; right to return provisions apply |
| Condo conversion | Yes (no-fault); relocation required; conversion process separate | Yes (no-fault); very restricted — SF condo conversion lottery highly limited |
| Ellis Act withdrawal | Yes (no-fault); relocation required; 5-year rental moratorium | Yes (no-fault); relocation required; 5-year moratorium, 10-year right of first refusal |
| Demolition | Yes (no-fault); relocation required; permit required | Yes (no-fault); relocation required; permit required; strict notice timelines |
| Breach of agreement to vacate | Yes | Yes |
Berkeley's Protected Classes: Enhanced Defenses
Berkeley has specific eviction protections for long-term tenants (10+ years), disabled tenants, tenants with minor children during the school year, and tenants over age 60. Even a valid legal ground may not be sufficient to evict these protected classes in certain circumstances. The presence of a qualifying protected tenant can make a legitimate OMI eviction procedurally impossible or legally risky — even if every other requirement is met. Before proceeding on any no-fault ground in Berkeley, confirm the tenant's protected status with a Berkeley tenants' rights attorney and a Berkeley Rent Board counselor.
San Francisco's Protected Tenants: Layered Complexity
San Francisco's tenant protection ecosystem is equally layered. Long-term tenants (generally 10+ years), elderly tenants (60+), disabled tenants, and low-income tenants have enhanced protections against owner move-in and certain other no-fault grounds. The SF Rent Board's "Protected Tenants" category can block an otherwise valid OMI if the landlord has a comparable unit in the building that could be occupied instead. SF also imposes a 3-year limitation on OMI evictions in buildings where a prior owner conducted an OMI — check the property history carefully.
Both cities have active tenant legal aid organizations — Centro Legal de la Raza (East Bay), Bay Area Legal Aid, and Tenderloin Housing Clinic (SF) among others. These organizations aggressively defend tenants facing no-fault evictions and frequently identify procedural defects in landlord filings. The cost of a wrongful eviction defense, including attorney fees and potential triple damages, can easily exceed $100,000. Engage qualified landlord-side counsel before filing any no-fault eviction notice in either city.
Relocation Requirements and Amounts
Both cities require relocation assistance when a tenant is displaced through a no-fault eviction. The amounts are substantial and have increased significantly over the past decade as Bay Area rents have climbed. Here's the framework — always verify current figures with the respective rent boards before proceeding with any no-fault eviction.
Berkeley Relocation Formula
Berkeley's relocation assistance is based on a formula that considers the number of months of comparable market rent, tenant income, length of tenancy, and protected status. As a general baseline for a standard no-fault eviction (owner move-in or Ellis), expect a minimum of two to three months of comparable market rent. Tenants who have lived in the unit for five or more years are entitled to enhanced amounts. Low-income tenants, elderly tenants (62+), disabled tenants, and households with minor children are entitled to additional relocation assistance — often doubling or tripling the base amount. The Berkeley Rent Stabilization Board updates the schedule periodically; confirm current figures at berkeleyca.gov/rentboard before issuing any notice.
San Francisco Relocation Amounts
San Francisco's relocation assistance amounts are set by the SF Rent Board and adjusted annually. For 2026, a typical OMI relocation for a 2-bedroom unit in a desirable SF neighborhood can run $20,000 to $35,000 for a single tenant. For long-term tenants (10+ years) in protected categories, amounts can be substantially higher. Ellis Act relocation for a 6-unit building with multiple long-term tenants regularly produces total relocation obligations exceeding $200,000 to $400,000 depending on unit size, tenant tenure, and protected status. SF relocation is among the highest in California — and it is one of the primary reasons SF multi-family buildings trade at significant discounts relative to their gross rent multipliers.
| Relocation Factor | Berkeley | San Francisco |
|---|---|---|
| Standard no-fault baseline | 2–3 months comparable market rent | Set by Rent Board schedule (verify at sfgov.org/rentboard) |
| Long-term tenant enhancement | Enhanced formula for 5+ year tenants | Enhanced amounts for 10+ year tenants |
| Protected class enhancement | Additional 1–2 months for elderly, disabled, low-income, families with children | Additional amounts for elderly (60+), disabled, low-income, catastrophically ill |
| Ellis Act 6-unit scenario | Varies; model $50,000–$150,000+ total depending on tenancies | Varies; model $200,000–$400,000+ total for long-term tenancies |
| Payment timing | Due at departure (unless agreed otherwise) | Installment options may apply; confirm with Rent Board |
| Verification source | berkeleyca.gov/rentboard | sfgov.org/rentboard |
If your acquisition plan involves reclaiming any units — for personal use, for renovation, or via Ellis Act withdrawal — build the full relocation cost into your purchase price underwriting before closing. This is not an operating expense you can absorb post-acquisition; it's a capital cost that should reduce your offer price dollar for dollar. An SF 4-unit building where all four tenants have lived there for 12+ years may carry $300,000 or more in relocation exposure — that figure should be baked into your cap rate math, not discovered after you close.

Call (510) 277-4420Exit Cost Comparison: Ellis Act and Owner Move-In
The two main exit paths from rent control are the Ellis Act (full withdrawal from the rental market) and owner move-in (OMI) eviction. Both are available in Berkeley and San Francisco, but the costs, restrictions, and strategic implications differ substantially between the two cities.
Ellis Act: Withdrawing from the Rental Market
The Ellis Act is a California state law that gives landlords the right to go out of the rental housing business entirely. It cannot be used to evict tenants from one unit while keeping others rented — you must withdraw all units in the building from the rental market simultaneously. The Ellis Act is primarily used by buyers who intend to convert a multi-unit building to condos, live in the entire building as a single-family residence, or redevelop the site.
In both cities, the Ellis Act triggers a 120-day notice requirement (extended to one year for tenants who are elderly or disabled and have lived in the unit for at least one year). After withdrawal, a 5-year moratorium on re-renting the units applies. San Francisco also grants former tenants a right of first refusal if any unit is re-rented within 10 years of withdrawal. This right of first refusal significantly limits what an Ellis Act withdrawal actually accomplishes if redevelopment plans change.
Owner Move-In: The More Targeted Tool
Owner move-in allows a landlord or a qualifying relative (spouse, domestic partner, child, parent, sibling, grandparent, grandchild, or in SF, other defined relatives) to reclaim a specific unit for personal occupancy. Unlike Ellis Act, OMI does not require withdrawing the entire building — you can OMI one unit while continuing to rent others. However, the landlord must have a genuine intent to occupy the unit as their primary residence for at least 36 months (in both cities), and the unit must become available within 3 months of the notice being served.
| Exit Path | Berkeley | San Francisco |
|---|---|---|
| Ellis Act eligibility | Any landlord (qualifying withdrawal intent) | Any landlord (qualifying withdrawal intent) |
| Notice period (standard) | 120 days | 120 days |
| Notice period (elderly/disabled) | 1 year for elderly or disabled tenants (1+ years in unit) | 1 year for elderly, disabled, or catastrophically ill (1+ years in unit) |
| Post-withdrawal re-rental moratorium | 5 years | 5 years; plus 10-year right of first refusal for former tenants |
| OMI qualifying relatives | Spouse, domestic partner, child, parent, sibling, grandparent, grandchild | Spouse, domestic partner, child, parent, sibling, grandparent, grandchild, and additional qualifying relatives |
| OMI occupancy requirement | 36 months continuous primary residency | 36 months continuous primary residency |
| OMI — protected tenant restriction | Cannot OMI-evict tenants 60+ (10+ years in unit), disabled tenants, families with minor children during school year | Cannot OMI-evict certain senior and disabled tenants; restrictions apply based on age, disability, and tenure |
| OMI — comparable unit rule | Limited applicability | If a comparable vacant unit exists in the building, landlord may be required to use that unit instead |
| Prior OMI restriction | Check for prior OMI evictions in building history | If prior owner conducted OMI within 3 years, new owner may be blocked from OMI; check history |
Both cities have strong tenant legal communities and well-funded nonprofit advocacy organizations. A flawed OMI or Ellis Act attempt that violates procedural requirements can result in wrongful eviction litigation, substantial damages, and the tenant being reinstated to the unit. In SF, wrongful eviction damages can include treble actual damages and attorney fees. Get qualified landlord-side counsel — not a general real estate attorney, but one who specifically practices landlord-tenant law in the relevant city — before filing anything. The difference in cost between doing it right and doing it wrong can be measured in six figures.

AB 1482: California's Statewide Backstop
Assembly Bill 1482, effective January 1, 2020, created statewide rent and eviction protections for units not covered by local ordinances. Understanding how AB 1482 interacts with Berkeley and SF rent control is essential for anyone evaluating a mixed-vintage building or a post-1979/1980 property in either city.
What AB 1482 Covers
AB 1482 applies to residential rental units in California that are not exempt and not covered by a more protective local ordinance. It caps annual rent increases at 5% plus the local CPI (maximum 10% total) and requires just-cause for eviction after a tenant has lived in the unit for 12 months. Key exemptions include: single-family homes (with proper notice to tenant), condominiums (with proper notice), units built within the past 15 years (rolling exemption based on building age), government-subsidized units, and units subject to a more protective local ordinance.
How AB 1482 Interacts with Berkeley and SF Law
For units already subject to Berkeley or SF rent control, AB 1482 is largely irrelevant — local law governs because it provides more tenant protection. The state law functions as a backstop for the gap category: units that fall outside local rent control (because they were built after the local cutoff or are otherwise exempt) but are old enough (15+ years) to be subject to AB 1482.
The practical impact: a post-1980 Berkeley apartment building (not subject to local rent caps) that is more than 15 years old is likely covered by AB 1482. A 1992-built Berkeley fourplex is not subject to Berkeley's rent cap ordinance, but it may be subject to AB 1482's 5%+CPI cap. Post-1995 new construction is exempt from AB 1482 until the building turns 15 years old — after which the exemption expires and AB 1482 applies.
AB 1482's 15-year age exemption is not permanent — it rolls forward with time. A building constructed in 2010 became subject to AB 1482 in 2025. A building constructed in 2012 becomes subject in 2027. If you're buying a building in the 10–14 year age range, factor in the upcoming AB 1482 compliance requirement. Landlords who are unaware of this transition sometimes impose above-limit increases in the years just before coverage kicks in — creating potential liability if they've misread the timeline.
Investor Perspective: Buying Into Rent Control
Rent-controlled properties in Berkeley and San Francisco trade at deep discounts relative to their potential market-rate income. That discount is both the opportunity and the risk. I've analyzed dozens of rent-controlled acquisitions in both markets. Here is the real framework for evaluating whether a specific building makes sense as a buy.
The Core Equation: Controlled Income vs Market Potential
Every rent-controlled acquisition has two income figures: the current controlled rent and the market rent. The gap between them is your unrealized upside — but that upside is only accessible through voluntary turnover or a legal exit path. The wider the gap, the more you're acquiring a discounted cash flow asset. The question is whether the discount is priced into the purchase price, and whether the path to closing the gap is realistic given tenant tenure and protected status.
Berkeley historically sees higher voluntary turnover than San Francisco. Berkeley's tenant population includes a significant proportion of graduate students, young professionals, and early-career tech workers who cycle through units on 1–3 year timelines. San Francisco's most deeply controlled units tend to be occupied by long-term residents — sometimes multi-decade — in desirable neighborhoods. The Bay Area tech economy sustains demand in both markets, but the voluntary turnover rate is a fundamentally different underwriting variable in each city.
-
Step 1: Identify the gap between controlled rent and market rent for each unit
A unit renting at $1,400/month in a $3,200/month market is deeply discounted — but also the most likely to turn over. A unit at $2,900 in a $3,100 market has minimal gap, minimal discount, and minimal upside. Map the gap by unit before you evaluate the deal as a whole.
-
Step 2: Model annual income growth at the controlled rate over your hold period
At 1.5% annual increases, a $2,000 controlled rent becomes $2,347 in 10 years and $2,762 in 20 years. Compare that trajectory to estimated market rents over the same period. For short holds (under 7 years), income growth from the ordinance is minimal. For long holds with voluntary turnover assumptions, the math can produce compelling returns — but sensitivity to turnover rate is high.
-
Step 3: Price the exit scenarios into your acquisition offer
Even if you never plan to exit, a buyer after you will. The market discounts rent-controlled buildings for the exit cost burden. Understand the full Ellis Act and OMI cost stack so you can negotiate your acquisition price to reflect what the next buyer will face. Buildings with heavily tenured, protected tenant populations carry embedded exit costs that should reduce your offer price accordingly.
-
Step 4: Track tenant tenure and protected status as underwriting risk variables
A 3-year tenant is not the same risk profile as a 15-year tenant who is over 60 and disabled. Request the full rent roll with move-in dates and any known protected status before closing. Long-term protected tenants create relocation exposure that can represent a significant portion of a building's value — it must be modeled explicitly, not assumed away.
-
Step 5: Evaluate Costa-Hawkins-exempt units separately from controlled units
If the building has a mix of rent-controlled and exempt units (e.g., a post-1995 addition, a SFR carriage house, or a converted garage unit), evaluate each unit type separately on its own income trajectory and exit flexibility. Exempt units provide market-rate upside and different relocation exposure — they should be modeled under different assumptions from the controlled units in the same acquisition.
There is no universal answer — it depends on your strategy, your hold period, and your tolerance for legal complexity. Berkeley tends to offer higher voluntary vacancy turnover and a somewhat lower cost basis for comparable building types. San Francisco offers deeper liquidity, stronger long-term appreciation in desirable neighborhoods, and a more established market for TIC conversions and condo conversions. Both markets have strong fundamentals driven by constrained supply and persistent demand from the technology economy. Both require a legal framework that investors in other markets simply don't encounter.

This is the due diligence framework I use when evaluating rent-controlled acquisitions in either market. Work through each step before making an offer — not during the inspection contingency, and certainly not after closing.
-
Confirm construction date and unit type from building permits
Pull the building permit, not just the listing. Berkeley's cutoff is January 1, 1980. SF's is June 15, 1979. Verify with the Alameda County Assessor (Berkeley) or SF Assessor-Recorder (SF). Beware of buildings that were substantially rebuilt or retrofitted — the permit date for the original structure governs, not the retrofit date.
-
Request the complete rent roll and lawful base rent history for each unit
Ask the seller for the full rent history: original base rent, all annual increases (with dates and notice documentation), any above-guideline increase petitions filed or approved, and any tenant petitions or complaints filed against the building. Unpermitted above-guideline increases create retroactive liability. A unit with 15 years of undocumented increases is a legal time bomb — price it accordingly or request a rent reduction agreement from the seller as a condition of purchase.
-
Verify coverage status for each unit with the relevant rent board
Do not rely on the listing agent's characterization of coverage. Call the Berkeley Rent Stabilization Board (510-981-7368) or SF Rent Board (415-252-4602) directly and request a coverage confirmation for the specific address. This call is free, takes 10 minutes, and is the most important due diligence step on any rent-controlled acquisition.
-
Calculate rent-controlled cap rate and model voluntary turnover scenarios
Run the cap rate at current controlled rents (conservative base case) and at market rents (upside case). Then model intermediate scenarios based on realistic turnover assumptions: 1 unit in year 2, 2 units in year 5. Does the deal work at current controlled rents alone? If the entire investment thesis depends on rapid voluntary turnover, stress test the assumption — some Berkeley and SF tenants stay for decades.
-
Determine tenant tenure and protected status for every unit
Request a certified rent roll from the seller that includes move-in dates for every tenant. If any tenant is over 60, disabled, low-income, or has school-age children, document it now and price in the enhanced relocation exposure. Protected tenants that cannot be OMI-evicted eliminate one of your primary exit options — factor that into the acquisition price.
-
Model full exit costs before signing a purchase contract
Run every plausible exit scenario: hold and collect controlled rents, OMI one unit, Ellis Act withdrawal, sell tenant-occupied. Model the cost of each path against the purchase price and expected appreciation. In SF, a building where Ellis Act withdrawal would cost $350,000 in relocation should trade at a price that reflects that embedded liability — negotiate accordingly.
Most buyers who get hurt by rent control get hurt not because the rules are unfair, but because they didn't understand the rules before they closed. The ordinances are public, the rent boards are accessible, and the math is modelable. The investors who make money consistently in Berkeley and SF are the ones who ran the full analysis — income ceiling, exit cost, tenant profile — before signing anything.

Frequently Asked Questions
These are the questions buyers, landlords, and investors most frequently ask about Berkeley and San Francisco rent control. Each answer reflects the current 2026 framework — always verify specifics with the Berkeley Rent Stabilization Board or the SF Rent Board before taking action.
Which city has stronger rent control — Berkeley or San Francisco?
Berkeley's rent control is generally considered stronger in terms of coverage breadth and annual increase limits. Berkeley allows annual increases of only 65% of CPI (historically 1–2%), while San Francisco allows 60% of CPI with a 1% minimum floor. Berkeley's Rent Stabilization Board is an elected body with independent adjudicative authority. Berkeley also extends just-cause eviction protections more broadly to post-1980 units through Measure EE.
That said, San Francisco's legal ecosystem around tenant rights is more developed, with better-resourced tenant legal aid organizations, a longer body of case law, and more aggressive Rent Board enforcement of landlord procedural violations. "Stronger" depends on what you're measuring — in practice, both cities require the same level of diligence from landlords and buyers.
Does Berkeley rent control cover single-family homes?
No rent caps — Costa-Hawkins preempts Berkeley from controlling rents on single-family homes and condos. However, Berkeley's just-cause eviction rules still apply to those units even without rent caps. This is one of the most commonly misunderstood distinctions in Berkeley real estate. A buyer who purchases a Berkeley SFR expecting to be able to remove a tenant freely will find that they still need a valid just-cause ground — they simply are not constrained on the rent amount if the unit turns over voluntarily.
What is the rent increase percentage in San Francisco for 2026?
For 2026, San Francisco's allowable rent increase is approximately 1.4%, effective March 1, 2026 (60% of the Bay Area CPI). This figure changes annually. Always verify the current allowable increase percentage at sfgov.org/rentboard before issuing any rent increase notice. Issuing a rent increase above the allowable percentage is an unlawful rent increase under San Francisco law — the tenant can petition the Rent Board for a reduction and the landlord may face penalties.
Can a new owner of a Berkeley duplex raise rents to market rate?
Only if the tenant voluntarily vacates. Costa-Hawkins requires vacancy decontrol — rents reset to market rate on a tenant's voluntary departure. But a purchase transaction does not trigger vacancy decontrol. If the prior tenant is in the unit when you close, their tenancy continues at the same controlled rent as before. You cannot evict to reset rents, and you need a valid just-cause ground to remove a tenant at all. Plan on inheriting the current controlled rent — model the deal that way, and treat voluntary turnover as upside rather than base case.
Are there relocation payments required for no-fault evictions in both cities?
Yes, in both Berkeley and San Francisco. Relocation assistance is required for all no-fault evictions — owner move-in, Ellis Act, substantial rehabilitation, demolition, and others. The amounts are substantial and vary based on tenant income, length of tenancy, unit size, and protected status. In San Francisco, Ellis Act relocation for a large building with long-term, protected tenants can exceed $400,000 in total payments. In Berkeley, amounts are lower but still significant. Verify current figures with the Berkeley Rent Stabilization Board (berkeleyca.gov/rentboard) and the SF Rent Board (sfgov.org/rentboard) before proceeding with any no-fault eviction.
Do new condos built after 1995 have to follow Berkeley or SF rent control?
No rent caps under local ordinances — Costa-Hawkins exempts units first occupied after February 1, 1995 from local rent caps. But AB 1482 statewide law applies once the building is over 15 years old, limiting annual increases to 5% plus local CPI (maximum 10%). Additionally, just-cause eviction obligations may still apply under local ordinances even for Costa-Hawkins-exempt units — particularly in Berkeley under Measure EE and in San Francisco under Admin Code Chapter 37A. The exemption from rent caps does not mean the unit is fully deregulated.
What happens to rent control when you buy a tenant-occupied property in San Francisco?
The tenancy transfers with the property. All rent control protections that applied before the sale continue after the sale — the buyer inherits the tenant's lawful base rent, accrued tenure, and any protected status. The new owner has the same obligations as the prior landlord from the moment the sale closes. This is why a thorough pre-purchase review of the rent roll, rent history, and tenant protected status is essential — not optional — before closing on any tenant-occupied property in San Francisco. Contact (510) 277-4420 to work through this review before making an offer.
How does AB 1482 interact with Berkeley and SF rent control?
AB 1482 is California's statewide rent protection law (effective January 2020). It caps annual rent increases at 5% plus local CPI (maximum 10%) and requires just-cause for eviction after 12 months of tenancy. In Berkeley and San Francisco, local ordinances are more protective — lower caps, broader just-cause requirements — so local law governs for units subject to those ordinances. AB 1482 functions as a backstop for units that fall outside local rent control (post-cutoff buildings over 15 years old) but aren't exempt from state law. The 15-year exemption is a rolling window — buildings built in 2010 became subject to AB 1482 in 2025. Factor this into due diligence on newer buildings in both cities.
