Key takeaways
- Berkeley — registration required; primary-residence rule similar to SF.
- Palo Alto — short-term rentals largely restricted to home-sharing.
- Fremont — STR ordinance under active revision; check city directly.

California state law does NOT prohibit renting an ADU as a short-term rental (Airbnb, VRBO, stays under 30 days). However, state ADU law explicitly preserves the right of cities and counties to regulate short-term rentals through their own ordinances. The result: a fragmented patchwork where the same ADU is fully Airbnb-legal in one city and effectively banned in the next.
Los Angeles — Home-Sharing Ordinance
Under LA's Home-Sharing Ordinance, short-term rentals are restricted to the operator's primary residence (defined as 6+ months/year). A standalone ADU rented purely as a short-term rental is generally NOT permitted in the City of Los Angeles. Hosts must register, pay TOT, and stay within a 120-night annual cap unless they obtain an Extended Home-Sharing approval. JADUs are explicitly excluded from short-term rental use.
Unincorporated LA County, West Hollywood, Santa Monica, Pasadena, Long Beach, and Burbank each have separate ordinances — check the local code, not the LA City rule.
San Francisco — Office of Short-Term Rentals
San Francisco allows short-term rentals only in the operator's primary residence (275-night cap for un-hosted stays, no cap if hosted). A non-owner-occupied ADU cannot legally be rented short-term in SF. Hosts must register with the OSTR and renew annually.
Oakland
Oakland permits short-term rentals only at the operator's primary residence with an annual permit. Detached ADUs at a primary residence may qualify if the owner lives in the primary house. See Oakland ADU permit rules for context.
San Jose
San Jose allows un-hosted short-term rentals up to 180 days/year with a permit. Hosted stays (the host is on-site) have no day cap. An ADU at the host's primary residence qualifies. See San Jose ADU permit rules.
Bay Area suburbs — quick read
- Berkeley — registration required; primary-residence rule similar to SF.
- Palo Alto — short-term rentals largely restricted to home-sharing.
- Fremont — STR ordinance under active revision; check city directly.
- Walnut Creek, San Mateo — generally allow with permit + TOT.

Why this matters more than people think
Many ADU pro-formas assume Airbnb income at 1.5–2× long-term rent. In California's two largest metros, that assumption is illegal in most cases. A safer underwriting model uses long-term rental benchmarks — see LA ADU rent data and Bay Area ADU rent data.
Tax considerations
Short-term rentals generate Transient Occupancy Tax (TOT) obligations in every California jurisdiction, typically 10–15% of nightly rent. Long-term rentals don't trigger TOT but follow different income tax treatment. Property tax reassessment from building the ADU itself is covered in our property tax guide.

FAQ · Permitting
Common questions on permitting
The questions readers send us most after this guide.
What is SB-9 and does it apply to me?
SB-9 (the California HOME Act) lets eligible single-family lots split into two parcels and/or add a duplex. We assess eligibility during the feasibility call — roughly 60% of LA single-family lots qualify on paper, fewer in practice once HPOZ, hillside, and coastal overlays are applied. SB-9 projects can stack with an ADU for up to four units on what was a single-family lot.What about hillside or coastal lots?
Hillside requires a Methane District review (where applicable) plus a haul route plan if grading exceeds 1,000 cubic yards. Coastal Zone projects (anything west of Lincoln Blvd in Venice, for example) need a Coastal Development Permit on top of standard LADBS approval. Both are workable; both add 60–90 days.I'm in an HPOZ — can I still build?
Yes, but with design review. Historic Preservation Overlay Zones require Certificate of Appropriateness from the cultural heritage commission before permits issue. We've shepherded projects through Miracle Mile, West Adams, Whitley Heights, and Spaulding Square HPOZs. Add 8–12 weeks for the COA process.Do you handle the permitting?
Yes. We file with LADBS or your local building department, manage plan check, coordinate utility upgrades, schedule inspections, and deliver final sign-off. You don't visit the counter, we do.What setbacks and height limits apply?
Statewide ADU law (AB 68/881) overrides most local restrictions: 4-foot side and rear setbacks, 16-foot height for detached one-story, 18-foot for two-story within ½ mile of transit. Front setbacks follow the underlying zone. We model your envelope at the schematic stage.How long does an ADU project take in Los Angeles?
Most detached ADUs run 9–13 months from contract to certificate of occupancy. Garage conversions are typically 4–6 months. Permitting alone is usually 60–120 days at LADBS depending on whether we use a pre-approved standard plan or a custom design that needs full plan check.

How long does a ADU permit take in Beverly Hills?
City of Beverly Hills Community Development runs plan check 120–180 days on a complete, code-conformant submittal for a ADU. First-cycle approvals depend on three things: a stamped structural set, a Title 24 energy report bound into the package, and a site plan with verified setbacks. Most slippage comes from missing one of those three on first submittal.Why do ADU permits get rejected in Beverly Hills?
In Beverly Hills, the five most common first-cycle corrections are: (1) Title 24 energy compliance not bound to the submittal, (2) site plan setback math off by inches, (3) structural calcs not stamped by a CA-licensed engineer, (4) utility load calculations missing for the panel upgrade, and (5) drainage/grading not addressed for impervious-surface adds. Fixing all five before submittal cuts 120–180 days off the schedule.Does state ADU law override Beverly Hills rules for my ADU?
For qualifying ADU and JADU scopes, California Government Code §65852.2 and §65852.22 preempt most local discretionary review — Beverly Hills cannot impose owner-occupancy requirements (banned by AB 976), most parking minimums near transit, or stylistic design review. Local jurisdictions still control building-code application, Title 24, utility connection, and impact fee schedules. Non-ADU scopes (full additions, remodels, hillside builds) remain fully under local control.Are pre-approved standard plans available in Beverly Hills for a ADU?
Where Beverly Hills has adopted a pre-approved standard ADU plan program, using one cuts plan check by 30–60 days and removes the structural review fee. For programs that exist (LADBS, San Jose, San Diego), the trade-off is that floor-plan changes void the pre-approval. Most owners are better off using a standard plan as a starting point and accepting the layout it ships with.How long does a garage conversion permit take in Beverly Hills?

ADU vs SB9 lot split: which path actually fits your lot
Two state laws now let LA homeowners add density. SB9 splits the lot and creates a separately sellable parcel; ADU law adds a unit. The decision turns on three numbers — and one local opt-out.
