Can You Airbnb an ADU in Los Angeles?
Justin Borges, DRE #01940318 · 12 min read · Updated July 26, 2026
Generally no. An ADU that is not the host's actual primary residence cannot be legally short-term rented in the City of Los Angeles. Two separate rules block it: state law lets a city require ADU rentals to run 30 days or longer, and the LA Home-Sharing Ordinance requires the rented unit to be the host's actual primary residence, not a secondary or investment unit (Gov. Code Section 66315; LA City Planning Home-Sharing Ordinance No. 185,931).

Can You Airbnb an ADU in Los Angeles?
Generally no, and the reason is two separate rules stacking on top of each other rather than one single ban. State law gives a Los Angeles County city the option to require ADU rentals to run 30 days or longer, which by itself forecloses nightly or weekend rentals (HCD, minimum 30-day ADU rental term local agencies may require, per Gov. Code Section 66315).
Separately, the City of Los Angeles Home-Sharing Ordinance only allows short-term rental of a host's actual primary residence. Most ADUs are rented out while the owner lives in the main house, which means the ADU itself is not the host's primary residence, and does not qualify.
The honest answer is: if you actually live in the ADU and rent out the main house short-term, that can work. If you live in the main house and want to Airbnb the ADU, it generally does not.
Justin Borges, CA DRE #01940318What Does State Law Say About Renting Out an ADU Short-Term?
California's ADU statute permanently prohibits any owner-occupancy requirement, but it separately preserves a different lever for local agencies: a city may require ADU rentals to run 30 days or longer (HCD, permanent owner-occupancy prohibition, distinct from the rental-term rule, under Gov. Code Section 66315). Los Angeles has exercised that option, and it is the specific legal mechanism that forecloses nightly or weekly rental of most Los Angeles County ADUs regardless of what the Home-Sharing Ordinance separately requires.
This rental-term authority sits inside the same statutory chapter that sets an ADU's allowable size and height across Los Angeles County (HCD, ADU size and height standards, per Gov. Code Section 66321), and the whole framework is current through SB 543's amendments, effective January 1, 2026 (HCD, ADU statutory framework, current through SB 543, effective January 1, 2026).
What Is the Los Angeles Home-Sharing Ordinance?
Ordinance No. 185,931 lets a Los Angeles host rent their primary residence short-term for up to 120 days a year with basic registration, or beyond 120 days with Extended Home-Sharing approval, which requires a clean citation history and, in some cases, a public hearing (LA City Planning Home-Sharing FAQ; reported via secondary sources, confirm current details directly with LA City Planning).
| Rule | Requirement |
|---|---|
| Eligible unit | Host's actual primary residence only |
| Annual cap, standard registration | 120 days per calendar year |
| Extended Home-Sharing eligibility | No more than one citation in the preceding 3 years; may require a public hearing |
| ADU eligibility | Only if the ADU is genuinely the host's primary residence, not a secondary rental unit |
Does Your ADU Qualify as Your Primary Residence?
Only if you genuinely live there full time. A Los Angeles homeowner who lives in the main house and rents out the ADU as a separate unit does not meet the primary-residence test, no matter how the property is described in a listing or an application. An owner who actually moves into the ADU and rents the main house instead can potentially register the ADU as the home-shared unit, since it is then the true primary residence.
This distinction matters because it is the exact misconception this article exists to correct: owning an ADU does not, by itself, create a second short-term rental opportunity on the same Los Angeles County lot.
What Happens If You Operate an Unregistered Short-Term Rental in Los Angeles?
Operating beyond the 120-day cap without Extended Home-Sharing registration can draw a fine of approximately $2,000 per day, or two times the nightly rate charged, whichever is greater, according to LA City Planning's Home-Sharing Administrative Guidelines; confirm the current amount directly with LA City Planning, since this figure is reported through secondary sources rather than a document LAMH independently re-verified this cycle.
Enforcement in Los Angeles typically starts with a notice of violation, and if the activity does not stop, moves to a citation through the city's Administrative Citation Enforcement and Administrative Nuisance Abatement programs, with repeat violations able to suspend or revoke a registration entirely.
How Is Home-Sharing Different From a Long-Term ADU Rental?
A long-term ADU rental, generally 30 days or longer, sidesteps both the state-law rental-term rule and the City of Los Angeles Home-Sharing Ordinance's primary-residence requirement entirely, since neither rule targets rentals of that length. Most Los Angeles County ADU owners generating rental income are doing exactly this: a standard month-to-month or annual lease rather than a nightly platform listing.
Long-term rental income is also the figure most relevant to an actual ROI calculation for a Los Angeles County ADU, since it is legally available to virtually every ADU owner, unlike short-term hosting.
Can You Rent Your ADU on a 30-Day Minimum Instead of Nightly?
Yes, and for most Los Angeles County ADU owners this is the realistic path to rental income from the unit. A 30-day-or-longer lease avoids the short-term rental restriction entirely and does not require Home-Sharing registration, a citation-free history, or a discretionary hearing.
- No home-sharing registration needed. A standard lease of 30 days or more falls outside the Home-Sharing Ordinance entirely.
- No primary-residence test. The 30-day-minimum path does not require the owner to live in the ADU.
- Compare to our ADU ROI guide. Construction cost and long-term rent estimates for Los Angeles ADUs are covered in a companion guide on this site.
One more myth worth closing out here: an ADU cannot currently be sold as a separate condo unit in the City of Los Angeles either, since the city has not adopted an AB 1033 condo-conversion ordinance (HCD ordinance-review letter, confirming Los Angeles has not adopted an AB 1033 condo-conversion ordinance, August 2025). Rental income, long-term or otherwise, remains the realistic return path for a Los Angeles ADU today.
Frequently Asked Questions
Can you Airbnb an ADU in Los Angeles?
Generally no. An ADU that is not the host's actual primary residence cannot be legally short-term rented in the City of Los Angeles, since the Home-Sharing Ordinance requires the rented unit to be where the host actually lives, and state law separately lets the city require ADU rentals to run 30 days or longer (Gov. Code Section 66315; LA City Planning Home-Sharing Ordinance No. 185,931).
What is the minimum rental term for an ADU in Los Angeles?
State law allows a local agency to require ADU rentals to run 30 days or longer, and this is the specific legal hook that blocks nightly or weekly short-term rental of most ADUs (Gov. Code Section 66315).
What is the Los Angeles Home-Sharing Ordinance?
Ordinance No. 185,931 allows a host to rent out their primary residence short-term for up to 120 days a year with registration, or beyond that with Extended Home-Sharing approval. The unit being rented must be the host's actual primary residence, not a secondary or investment unit like most ADUs (LA City Planning Home-Sharing FAQ).
Does your ADU qualify as your primary residence for home-sharing?
Only if you genuinely live in the ADU full time and rent out the main house, or otherwise treat the ADU as your actual home. An ADU used as a rental unit while the owner lives in the primary house does not qualify as a primary residence for home-sharing purposes.
What happens if you operate an unregistered short-term rental in Los Angeles?
Operating beyond the 120-day annual cap without Extended Home-Sharing registration can draw a fine of approximately $2,000 per day or two times the nightly rate charged, whichever is greater, according to LA City Planning's Home-Sharing guidance; confirm the current amount directly with LA City Planning before assuming it has not changed.
Can you rent your ADU on a 30-day minimum instead of nightly?
Yes. Renting an ADU for 30 days or longer sidesteps both the state-law short-term rental restriction and the City of Los Angeles Home-Sharing Ordinance's primary-residence requirement, since neither rule targets rentals of that length.
