ADU permits in Westwood
Westwood is a major Westside Los Angeles neighborhood of about 47,000 people, anchored by the UCLA campus + the Wilshire Corridor's dense condo high-rises. Single-family Accessory Dwelling Unit (ADU) opportunities concentrate in Westwood Hills and the south-Holmby-adjacent pockets. Premium home values + persistent UCLA-driven rental demand make these ADU economics among the strongest on the Westside.

What you can build in Westwood
Westwood is inside the City of Los Angeles, so LADBS permits apply. Typical zoning in Westwood: R1-1, R3-1, R4-1. For these single-family zones, current LA City rules allow:
- Detached ADU. Up to 1,200 sqft, 16 ft tall (or 18 ft with second-story setbacks). 4 ft side/rear setbacks. One per lot.
- Attached ADU. Up to 50% of the primary house's living area, max 1,200 sqft. Must share a wall with the existing house.
- JADU (Junior ADU). Up to 500 sqft, inside the existing house footprint. Must have its own entrance. One per lot, in addition to a regular ADU.
- Two units per single-family lot. One full ADU + one JADU on the same SFR lot — allowed under LA's current rules. The combination is the highest density unlock without going SB 9.
- Parking exemption near transit. No replacement parking required if your lot is within ½ mile of a major transit corridor. Most lots within walking distance of Ventura Blvd, Sherman Way, or the Metro Orange Line qualify.
Recent CA + LA laws that affect Westwood ADUs
California has steadily loosened ADU rules since 2017. LA implements these through local ordinance. Here's what currently applies in Westwood:
AB 68
20201,200 sqft ADUs by right
Allowed detached ADUs up to 1,200 sqft on any single-family lot, removed owner-occupancy requirements through 2025, and capped permit processing time at 60 days. This is the foundation of the current LA ADU rules.
AB 671
2020Permit fee waivers for moderate-income ADUs
If you rent your ADU below market for the first 5 years, LA waives most permit and impact fees. Practical use is limited but it's the path that exists.
AB 332
2023School impact fees waived under 750 sqft
LAUSD's school impact fee — historically $2–4/sqft — is waived entirely for ADUs under 750 sqft. The YOU-ADU plan (455 sqft) qualifies, as do most JADUs.
SB 9
2022Lot splits + duplex conversions on R1
Separate from ADUs, but worth knowing: you can split certain R1 lots into two and build a duplex on each half. It's narrower than the headlines suggested and most LA homeowners still pursue the ADU path, not the SB 9 path, but check if you have a large flat lot.
AB 1033
2024Sell your ADU as a condo (LA opt-in pending)
Lets cities allow ADUs to be sold separately as condos. LA hasn't opted in yet (as of early 2026). Watch for it — would let homeowners build an ADU and sell it as a standalone unit.
LA Ordinance 187,712
2024Streamlined permits for pre-approved plans
LADBS now offers same-day permit issuance for ADUs built from a pre-approved standard plan (YOU-ADU or any LADBS-licensed designer plan). This is the fastest legal path from contract to building permit.

Streamlined permits for pre-approved standard plans
activeOrdinance No. 187,712 · Mar 2024
LADBS now offers same-day permit issuance for ADUs built from a pre-approved standard plan — the City's free YOU-ADU plan or any LADBS-licensed designer plan (ADU1–ADU96). This is the fastest legal path from contract to building permit in LA. Custom-designed ADUs still go through standard plan check.

pendingCouncil File 23-0843 · Nov 2024
LA City Council motion directing Planning + LADBS to study opting into AB 1033, which would let homeowners sell their ADU as a separate condo unit. Currently pending committee review. If LA opts in, ADUs become tradable real estate — major change for the homeowner economics conversation.

activeLADBS Information Bulletin P/BC 2024-160 · Apr 2024
Consolidates LADBS's ADU permit requirements into a single bulletin reflecting recent state law changes (AB 332 school fee waiver, AB 976 permanent owner-occupancy waiver). Worth bookmarking — this is the LADBS staff reference for ADU plan check.
Read the official text ↗School impact fee waiver for ADUs under 750 sqft
activeCalifornia AB 332 · Oct 2023
Permanently waives LAUSD's school impact fee (~$5/sqft) for any ADU 750 sqft or smaller. Saves $3,750 on a 750-sqft ADU; $0 vs. ~$5,000 on an 800-sqft ADU. The threshold is the single biggest fee-savings lever in LA ADU economics.
Owner-occupancy waiver made permanent
activeCalifornia AB 976 · Oct 2023
Permanently removed the owner-occupancy requirement that previously limited ADU rental flexibility. You can build an ADU on your property and rent it out without living on-site yourself. The original AB 68 (2020) waiver was set to sunset in 2025; AB 976 made it permanent.
Cities may opt-in to allow ADU condo sales (LA: not yet opted in)
passedCalifornia AB 1033 · Oct 2023
Allows California cities to opt into a program letting ADUs be sold as condos separately from the primary house. LA hasn't opted in yet (Council File 23-0843 is the pending study). When/if LA opts in, ADUs become standalone sellable units — major change for the build-as-investment conversation.
Streamlined permit timelines + unpermitted ADU amnesty path
activeCalifornia AB 2533 · Sep 2024
Caps local permit processing time at 60 days for non-discretionary ADU permits and creates a path for existing unpermitted ADUs to be legalized without retroactive penalties (if they meet current building code). LADBS implementation of the amnesty portion is rolling out through 2025.

Frequently asked questions about Westwood ADUs
›Can I build an ADU in Westwood?
Yes — Westwood is inside the City of Los Angeles, so the same LADBS rules apply as the rest of LA. Most single-family lots in Westwood (zoned R1-1, R3-1, R4-1) can host one ADU plus one JADU under current law. Run your specific address through the feasibility check on the homepage to confirm your zone and overlays.
›How much does it cost to build an ADU in Westwood?
Typical all-in cost for a permitted detached ADU in Westwood runs $150,000–$400,000+ depending on size, finish level, and whether you're on a flat lot or hillside. The free 455 sqft YOU-ADU plan keeps total cost low; HCD-prefab units (Connect Homes, Cover) are turnkey at $190K–$350K. Use the cost calculator linked above for a per-lot estimate.
›How long does the ADU permit process take in Westwood?
LADBS aims for 60-day plan check on ADU permits — and same-day issuance if you use a pre-approved standard plan (YOU-ADU or a licensed designer plan). In practice, custom plans average 4–7 months from submittal to building permit. Flat-lot Westwood permits are usually on the faster end of that range.
›Do I need a contractor with a specific license for an ADU in Westwood?
Yes — California requires a B (General Building) license for any structure with two or more trades, which describes essentially every ADU. You can owner-build, but most homeowners hire a licensed contractor.
›Does Westwood have an HPOZ (historic overlay) I need to worry about?
No — Westwood doesn't have an active HPOZ, so you skip the historic preservation review entirely. That's a meaningful time and cost savings compared to neighborhoods like Highland Park or Whitley Heights.
›What about the new CA ADU laws — do they apply in Westwood?
Yes. CA's recent ADU bills (AB 68 from 2020, AB 332 from 2023, AB 1033 from 2024, plus several others) all apply statewide and override stricter local ordinances. LA implemented them via Ordinance 187,712 in 2024, which streamlined permit issuance for pre-approved standard plans. Westwood sees the full benefit since LADBS is the permitting agency.
›Can I rent out the ADU on Airbnb in Westwood?
Short-term rentals (under 30 days) are restricted in LA City — you can only Airbnb your primary residence, not an ADU you don't live in, and there's a 120-night cap per year. Westwood is no exception. Long-term rentals (30+ day leases) are unrestricted and are the more common ADU monetization path.
›Do I need an architect or can I use a draftsperson?
For a pre-approved standard plan (YOU-ADU or a LADBS-licensed designer plan), neither — the plan is already drawn and stamped. For a custom ADU, a licensed architect or civil engineer must stamp the structural drawings. Draftsperson alone is not enough for the structural set.
Nearby areas to Westwood
Other Los Angeles-area pages worth a look. Each one runs different Accessory Dwelling Unit (ADU) rules depending on jurisdiction — we show you what changes when you cross a city or county line.
LA City
Bel-Air →
Premium hillside Westside estate community. Multi-acre lots support generous ADU footprints, but VHFHSZ + Bel-Air Association deed-restriction overlays + canyon-road construction logistics drive real cost.
LA City
Holmby Hills →
Among LA's most exclusive residential neighborhoods. Estate-scale lots make ADU footprint constraints irrelevant, but the build is almost always a guesthouse, not a rental investment.
LA City
Century City →
Westside high-rise commercial district. Single-family ADU applicability is limited to a small residential pocket on the south side; most of Century City is commercial or condo tower.
LA City
Brentwood →
Massive lots, high-end design norms, and heavy hillside / VHFHSZ exposure. Lower ADU volume than the Valley but higher per-project spend.
