Williamson Act Agricultural Land Near Sacramento 2026
Thousands of acres surrounding Sacramento, Elk Grove, Davis, and Rancho Cordova are under Williamson Act contracts. Before you make an offer on any rural parcel in the county's fringe, you need to understand what these contracts restrict, what it costs to exit one, and how they interact with Sacramento's unique planning landscape.

Most buyers who come to me asking about rural land in Sacramento County have seen a parcel priced lower than they expected. When I ask whether they have checked if the land is under a Williamson Act contract, the answer is almost always no. That is where the conversation needs to start. The Williamson Act is one of the most significant encumbrances that can affect agricultural and rural-residential land in California — and one of the least understood by buyers relocating from the Bay Area or Los Angeles.
This guide is not aimed at farming operations trying to maximize their ag subsidies. It is written for the buyer who wants a few acres outside the city for a small homestead, a rural retreat, a future build site, or a combination of uses. For those buyers, a Williamson Act contract can be either a modest inconvenience or a complete deal-breaker, depending on their plans. Understanding the distinction before you make an offer — not after — is the entire point.
Sacramento's land market is different from what Bay Area and LA transplants typically encounter. The Sacramento Valley floor surrounding the city is home to some of California's most productive farmland, and Sacramento County has been proactive about enrolling that land in agricultural preserves. At the same time, suburban expansion in the Elk Grove, Folsom, and Rancho Cordova corridors has pushed development pressure onto the agricultural fringe, creating a patchwork where contracted and unrestricted land sit side by side on the same road. Knowing which is which — and what that means for your purchase — is foundational.
What the Williamson Act Is and Why It Exists
The California Land Conservation Act of 1965, known universally as the Williamson Act, was created to slow the conversion of agricultural land to urban development. The state legislature in 1965 was watching Los Angeles, the Bay Area, and the Sacramento Valley get swallowed by suburban sprawl, and it created a mechanism to give landowners a financial incentive to keep land in agricultural or open space use.
The mechanism is a voluntary contract between a landowner and a county (or city). The landowner agrees to keep the land in agricultural or compatible use for a minimum of ten years. In exchange, the land is assessed for property tax purposes at its value for agricultural use rather than its market value for development. In areas where development pressure is high — which describes much of the Sacramento Valley fringe — this can reduce property taxes by 50% to 75% or more.
The catch is significant: the contract restricts development on the enrolled land and renews automatically each year unless the owner files a notice of non-renewal. When you buy land under a Williamson Act contract, you inherit the contract. You cannot buy the land and then immediately develop it just because you were not the one who signed the original agreement. The contract runs with the land, not with the seller.
Why This Matters for Sacramento-Area Buyers in 2025–2026
Sacramento's regional housing market has experienced sustained price appreciation over the past several years, driven largely by Bay Area and LA migration seeking affordability. Median prices in Sacramento County reached approximately $520,000 in 2025, up from $380,000 in 2020. This price growth has pushed buyers further into the county's agricultural fringe — areas east toward Rancho Murieta and Sloughhouse, south toward Galt, north toward Woodland, and into the Sacramento-San Joaquin Delta. Many of these parcels are exactly the ones carrying Williamson Act contracts, and the affordability that makes them attractive to buyers is partly a function of the restrictions they carry.
How Williamson Act Contracts Work
Williamson Act contracts have a self-renewing structure that is unusual in real estate. Each January 1, a ten-year contract automatically renews for another year unless the landowner files a notice of non-renewal with the county. This means a contract signed in 1980 is effectively a perpetual restriction unless someone actively takes steps to exit it. In Sacramento County, many enrolled parcels have been continuously under contract since the 1970s, renewed year after year by successive owners who valued the tax savings over development flexibility.
| Contract Feature | Standard Williamson Act | Farmland Security Zone (FSZ) |
|---|---|---|
| Minimum initial term | 10 years | 20 years |
| Automatic renewal | Yes, every January 1 | Yes, every January 1 |
| Transferability on sale | Transfers to buyer — binding | Transfers to buyer — binding |
| Cancellation penalty | 12.5% of fair market value | 25% of fair market value |
| Tax savings (approximate) | 50%–75% reduction | Up to 80% reduction |
| County enforcement | Sacramento County Board of Supervisors | Sacramento County Board of Supervisors + Dept. of Conservation review |
| Common locations | Ag fringe throughout county | High-value prime farmland (Class I–II soils) |
Sacramento County maintains both "prime" and "nonprime" agricultural preserves. Land in prime agricultural areas — typically defined by Class I and Class II USDA soil ratings — receives stronger protection and faces more scrutiny when cancellation is requested. Much of the Sacramento Valley floor, the flat terrain between Sacramento and Woodland and between Sacramento and Elk Grove, is enrolled in prime preserve. Buyers should be aware that prime-enrolled land faces higher barriers to cancellation than nonprime enrolled land.

The Property Tax Reduction: How It Is Calculated
The property tax benefit is the reason most landowners enter Williamson Act contracts in the first place. The calculation uses an income capitalization approach applied to agricultural income potential rather than the land's market value for residential or commercial development.
California Revenue and Taxation Code Section 423 specifies the formula. The land is assessed at the lesser of its market value for ag use or a capitalized value of net income from agricultural production. In practice, for Sacramento Valley farmland near the urban edge, the assessed value under Williamson Act is often 10%–25% of what the land would be assessed at for development purposes.
Example: 40-Acre Parcel, Sacramento County Fringe Near Elk Grove
These savings accumulate significantly over a 10–20 year ownership period. Over 15 years, the example above generates $272,250 in cumulative tax savings — a material economic benefit. The trade-off is accepting land use restrictions and the risk that you cannot develop if circumstances change. For buyers who genuinely want to use the land agriculturally or preserve its rural character, the Williamson Act contract is a benefit that should be factored into the purchase price analysis. For buyers who anticipate future development pressure unlocking value, it is a burden that should similarly be reflected in what you offer.
How Tax Assessment Transitions During Non-Renewal
Once a non-renewal notice is filed, the property tax does not jump immediately to full market value. Sacramento County schedules a gradual transition over the non-renewal period, with assessed value stepping up in roughly equal increments toward market value each year. For a 10-year non-renewal period, expect the tax obligation to increase by approximately one-tenth of the gap between ag value and market value annually. Buyers should model this trajectory carefully — the first few years of non-renewal often look affordable, but the final years can produce significantly higher carrying costs, particularly if development permits have not yet been secured.
What You Cannot Do with Contracted Land
Williamson Act contracts specify permitted and prohibited uses. The core rule: land under contract must be used for agriculture, open space, or compatible uses. What this means in practice for a private landowner in Sacramento County:
Generally Permitted
- Farming, grazing, orchards, row crops
- One primary residence (pre-existing or replacement dwelling)
- Farm worker housing (subject to county approval)
- Agricultural buildings (barns, equipment sheds, irrigation systems)
- Hunting, fishing, nature study, passive recreation
- Solar facilities on nonprime land (AB 1775 expanded this statewide)
- Small-scale agritourism where it supports the ag operation
- Kennels, equestrian uses, compatible rural enterprises
Generally Prohibited
- Subdivision of the contracted parcel into residential lots
- Commercial or industrial development unrelated to ag
- New residential subdivision (second dwelling units sometimes allowed with approval)
- Grading or grubbing without a compatible use finding
- Any use that materially impacts agricultural productivity
- Mining and extraction (unless pre-existing use before contract)
- Short-term vacation rentals as a primary use
- Storage facilities, RV parks, or unrelated commercial operations
Compatible Use Findings: When You Need One and How to Get It
Sacramento County's Department of Community Development reviews applications for compatible use findings on a case-by-case basis. A compatible use finding is essentially a formal determination by the county that the proposed use does not materially impair the agricultural productivity of the contracted land. The process involves submitting an application, paying a filing fee, and in some cases conducting an agricultural impact analysis prepared by a licensed agronomist.
Compatible use findings are more readily granted for uses that are clearly ancillary to agriculture — a barn conversion, a seasonal packing shed, a small agritourism operation. They are harder to obtain for uses that have little connection to farming — a private shooting range, a storage yard, a commercial event venue. Buyers who have specific non-agricultural uses in mind for a contracted parcel should consult with Sacramento County planning staff before making an offer, not after.
How to Cancel a Williamson Act Contract
Cancellation is the high-cost, fast-exit option. It requires county approval, which is only granted if the cancellation is consistent with the purposes of the Act or if the cancellation is in the public interest. In practice, Sacramento County rarely approves cancellations except in limited circumstances: eminent domain proceedings, large-scale public infrastructure projects, or extraordinary cases where the Board of Supervisors makes an explicit public benefit finding. Private landowner convenience is not a sufficient basis for cancellation.
The cancellation penalty is steep by design: the state receives a fee equal to 12.5% of the property's fair market value at the time of cancellation. For Farmland Security Zone contracts, the penalty doubles to 25%. This fee is paid to the California Department of Conservation and is not refundable under any circumstances. On a $2 million parcel, the standard cancellation fee is $250,000 before any legal, environmental, or processing costs. On an FSZ parcel, it is $500,000.
| Cancellation Element | Standard Williamson Act | Farmland Security Zone |
|---|---|---|
| State cancellation penalty | 12.5% of fair market value | 25% of fair market value |
| County approval required | Yes — Board of Supervisors vote | Yes — Board of Supervisors + Dept. of Conservation |
| CEQA review | Usually required (EIR or MND) | Full EIR typically required |
| Approval standard | "Consistent with Act purposes" or "public interest, no practical alternative" | Higher threshold — "extraordinary circumstances" standard |
| Practical timeline | 12–24 months (if approved at all) | 18–36 months (rarely approved) |
| Legal costs (estimate) | $25,000–$75,000+ | $50,000–$150,000+ |
| Recourse if denied | Non-renewal is the fallback; judicial appeal rarely successful | Non-renewal; near-zero judicial appeal success |
Buyers who are told by sellers or their agents that cancellation is "just a formality" or "straightforward" should be highly skeptical. Sacramento County has a strong agricultural land protection culture, and its planning staff typically recommends denial on most private cancellation applications. If a seller is representing that cancellation is imminent or approved, request documentary evidence — not verbal assurances.
Non-Renewal: The 9-Year Wind-Down Path
Non-renewal is the standard exit from a Williamson Act contract and the path used by the vast majority of landowners who eventually want to develop or convert contracted land. The landowner files a notice of non-renewal with the county assessor's office before January 1 of a given year. The contract then does not renew and instead winds down over the remaining term. Because contracts automatically roll for 10 years, a notice filed today means the contract expires approximately 9–10 years from now — the precise timing depends on where the contract is in its current annual cycle.
During the non-renewal period, all land use restrictions remain fully in effect. You still cannot subdivide or develop. The only thing that changes is that the clock is running toward expiration. Property taxes gradually increase over the wind-down period as the assessment transitions from ag capitalized value toward full market value, with the trajectory set by Sacramento County ordinance.
After the non-renewal period expires and the contract terminates, the land is free of Williamson Act restrictions. It reverts to its underlying zoning, which may or may not allow development depending on the General Plan and zoning designation. This is a critical point that many buyers miss: the end of a Williamson Act contract does not automatically rezone the land. The zoning follows the General Plan, which in Sacramento County may still be Agricultural (Ag-20, Ag-40, or similar large-lot ag designations) even after the contract has expired. A successful Williamson Act exit may still need to be followed by a General Plan amendment or zone change before any residential or commercial development can proceed — a separate and often lengthy entitlement process.

Due Diligence: 7-Step Checklist for Buyers
If you are considering any rural or ag-residential parcel in Sacramento County, here is the specific investigation I walk every buyer through before contingency removal. These seven steps are non-negotiable on any parcel where the price, location, or listing description suggests agricultural or rural-fringe zoning.
- Confirm Williamson Act Enrollment Request seller disclosure and independently verify with the Sacramento County Assessor's rural properties division. Do not rely on the seller's word alone. A Williamson Act contract is recorded against the title, so a thorough preliminary title report will also show it.
- Check Non-Renewal Status and Filing Date Ask the county when (or if) a notice of non-renewal was filed. A parcel with 4+ years already served on non-renewal is worth considerably more to a development-intent buyer than one just entering non-renewal. Verify the filing date with Sacramento County directly, not just through the seller or listing agent.
- Request the Actual Contract Document Some Sacramento County contracts include local restrictions beyond the state minimums set by the Williamson Act. Reading the specific contract document is the only way to know what you are actually inheriting. Request it from Sacramento County Department of Community Development.
- Check General Plan Land Use Designation and Zoning Verify with Sacramento County what the land is designated for under the General Plan and what zoning applies — both now and what would apply after the contract expires. Williamson Act expiration does not guarantee development rights; the General Plan designation governs.
- Run a USDA Web Soil Survey Identify whether the parcel contains Class I or Class II prime agricultural soils. Available free at websoilsurvey.sc.egov.usda.gov. Prime soils trigger stricter state standards for cancellation and make compatible use applications more difficult. This takes about 20 minutes and can meaningfully change the risk profile of a parcel.
- Check for Mello-Roos CFD and Special Assessments Especially in the Elk Grove, Folsom, and Rancho Cordova fringe areas, confirm whether the parcel falls within a Community Facilities District. Mello-Roos special taxes apply regardless of Williamson Act status and can add $2,000–$8,000+ per year to your carrying cost. Sacramento County LAFCO and the county assessor's website both provide CFD mapping.
- Consult a Land Use Attorney For any parcel over $500,000 or any parcel where your intended use may be restricted by the contract, a land use attorney review of the contract and General Plan designation is not optional — it is necessary. A $3,000–$5,000 legal review is cheap insurance against a $250,000+ cancellation penalty or a 10-year development delay.
| Item | How to Verify | Why It Matters |
|---|---|---|
| Williamson Act enrollment | Seller disclosure + Sacramento County Assessor rural division + title search | Contract transfers to buyer — you inherit all restrictions |
| Non-renewal filed? | Request filing date from county records | Determines how many years of wind-down remain |
| Current assessed value vs. market value | Sacramento County Assessor portal; compare to market comps | Tax burden changes substantially after contract expires |
| General Plan designation post-contract | Sacramento County Department of Community Development | Contract ending does not guarantee development rights |
| Specific contract terms | Actual contract document from county | Local restrictions may exceed state minimums |
| Existing residence on parcel? | Title review; county permit records | Affects whether you can add a dwelling without a compatible use finding |
| USDA soil classification | USDA Web Soil Survey (free) | Prime soil (Class I–II) increases barriers to cancellation and compatible use approvals |
| Mello-Roos CFD membership | Sacramento County LAFCO; county assessor CFD mapping | CFD special taxes apply independent of Williamson Act status — affects true carrying cost |
Sacramento County Specifics by City and Area
Sacramento County's Williamson Act program is administered through the Department of Community Development and Planning. The county maintains agricultural preserves that overlay several areas of the county, with the heaviest concentration in the delta, the southeast county near Elk Grove and Galt, and the north county toward Woodland and West Sacramento. Understanding the geographic distribution is important because Williamson Act risk varies considerably by location within the county.
Sacramento County also participates in the Farmland Security Zone (FSZ) program, which carries 20-year contract terms and doubled cancellation penalties. FSZ land is typically in the most productive agricultural areas and has more restrictive development rules than standard Williamson Act contracted land.
City of Sacramento
Incorporated land within city limits is generally not enrolled in Williamson Act. Urban parcels and established residential neighborhoods are not subject to these restrictions.
Elk Grove (Rural Fringe)
The southeast fringe beyond Elk Grove's city limits has significant Williamson Act concentration. Also check for Mello-Roos CFD districts — both can apply simultaneously on the same parcel.
Folsom / Rancho Cordova
Incorporated areas are generally unrestricted. Rural parcels east of Folsom toward Rescue and Shingle Springs may carry contracts. Folsom-area Mello-Roos CFDs are common on newer developments.
Davis / Yolo County
Davis is in Yolo County, not Sacramento County, but the pattern is similar: city limits are unrestricted; surrounding farmland is heavily enrolled. Davis is surrounded by agricultural preserves that have successfully resisted urban expansion for decades.
Natomas
Natomas is primarily a flood-zone concern (levee and FEMA flood map disclosures required) rather than a Williamson Act concern. Most Natomas parcels are within Sacramento city limits or urban-zoned land.
Sloughhouse / Rancho Murieta
High Williamson Act concentration in this rural corridor. Many parcels in this area are enrolled and some are FSZ. Buyers seeking acreage near Rancho Murieta should assume enrollment until verified otherwise.
How Sacramento's Measure Q Interacts with Rural Land
Sacramento's Measure Q just-cause eviction ordinance applies to residential rental units within the City of Sacramento. If you are purchasing an agricultural parcel in the unincorporated county or within a rural city, Measure Q does not directly apply. However, if the parcel includes an existing residential structure that is or could be rented, you should verify whether the property falls within an incorporated city boundary and whether any local just-cause eviction rules apply. This is more relevant for buyers considering the residential component of ag-residential parcels than for pure agricultural use buyers.

Financing Williamson Act Land
One dimension of Williamson Act purchases that buyers from urban markets often overlook is how the contract affects financing. Most conventional residential lenders — the major banks, mortgage brokers, and online lenders that handle standard home purchases in Sacramento, Roseville, and Folsom — are not set up to underwrite Williamson Act agricultural land. Their appraisers are trained on residential comparables, and a Williamson Act contract creates encumbrances that most residential appraisers have limited experience assessing.
Lender Types for Williamson Act Land
| Lender Type | Familiarity with Williamson Act | Best For | Notes |
|---|---|---|---|
| Farm Credit (AgFirst, Farm Credit West) | High — core competency | Agricultural operations, large parcels | Experienced with ag land appraisal and encumbrances |
| Farmer Mac | High | Agricultural mortgages $500K+ | Secondary market for farm loans |
| Small community banks in Sacramento Valley | Moderate to high | Smaller ag-residential parcels | Local knowledge; may have ag lending division |
| CalHFA programs (Dream For All) | Low | Down payment assistance on residential purchases | Not designed for agricultural land; likely inapplicable to Williamson Act parcels |
| Conventional conforming lenders (major banks) | Low | Standard residential purchases | May require special review; loan-to-value may be reduced on contracted land |
If your Sacramento land purchase includes a primary residence on the parcel, financing options expand. A lender can originate a residential mortgage on the dwelling and treat the land as collateral — but they will still scrutinize the Williamson Act encumbrance and may require a legal opinion on the contract's impact on title marketability. Plan for a longer underwriting timeline and potentially a lower LTV than you would receive on an unencumbered residential parcel.
For buyers using CalHFA's Dream For All down payment assistance program to purchase in the Sacramento area, note that this program is designed for primary residences in standard residential transactions. Agricultural land under a Williamson Act contract is almost certainly outside the program's guidelines. Dream For All is relevant for buyers purchasing homes in Sacramento, Roseville, Folsom, Elk Grove, or Lincoln — not for rural land acquisitions.

How the Williamson Act Affects Property Value
The effect of a Williamson Act contract on market value is complex and depends heavily on buyer intent. Here is how the three common buyer profiles experience it in the current Sacramento market:
The farmer or agricultural operator: For a buyer who wants to use the land for farming, the Williamson Act contract is a net benefit. Lower property taxes, protection from eminent domain for urban development, and a predictable land use framework. The contract does not reduce market value for this buyer — it may actually increase it, because the tax savings translate directly into reduced carrying costs and improved cash flow for the operation.
The rural lifestyle buyer (small hobby farm, private residence, homestead): This buyer can typically continue a primary residence use on contracted land and add compatible agricultural uses. The contract restricts subdivision and commercial development but does not prevent a buyer from living on the land and maintaining an agricultural use. Property taxes are meaningfully lower. For this buyer, the Williamson Act is a moderate benefit with some restrictions on future flexibility. The discount in purchase price relative to unrestricted rural residential land can be attractive if the buyer's horizon is long and development conversion is not the goal.
The speculative developer or investor: For a buyer who wants to unlock residential or commercial development value, the Williamson Act contract is a significant impediment. The cancellation path is expensive and uncertain. The non-renewal path takes 9–10 years and still does not guarantee development rights. Land under active Williamson Act contracts trades at a meaningful discount to comparable unrestricted land when the buyer intends development — that discount reflects the time value of the delay and the regulatory uncertainty about future rezoning.
Value Comparison: Sacramento County Ag Land (Per Acre, 2025 Estimates)
These estimates are rough guides, not appraisals. Specific parcel values depend on location, soil quality, water rights, access, proximity to urban services, and the specific terms of the contract. The point is directional: Williamson Act enrollment creates a real, measurable discount for development-intent buyers, and that discount is not uniform — it varies based on where the parcel sits in its non-renewal timeline and what the underlying General Plan allows after contract expiration.
