ADU permits in Woodland Hills
Woodland Hills is one of LA's largest single-family neighborhoods, with ~21,000 SFR lots in the western San Fernando Valley. Most parcels are zoned R1-1 and large enough to host a detached ADU under LA's standard rules — but the south side rises into the Santa Monica foothills, where hillside, fire-zone, and slope-specific permit requirements kick in. Knowing which side of Ventura Blvd you're on changes your cost and timeline substantially.

Permit overlays active in Woodland Hills
These are LA City zoning / regulatory overlays that hit a meaningful share of Woodland Hills parcels. Each one affects what you can build, how long it takes, or how much it costs. Run your specific address through the feasibility check on the homepage to see which apply to your lot.
Hillside Area
~35% of parcelsSouth of Ventura Blvd, much of Woodland Hills sits on LA's designated Hillside Area. Expect a +20% construction cost premium, possible geotech / soils report, and tighter setback enforcement.
Very High Fire Hazard Severity Zone
~25% of parcelsSouth-side hillside lots overlap the VHFHSZ. Adds Class A roofing, ember-resistant venting, and fire-rated wall assemblies — typically a ~7% construction premium on top of hillside.
GIRARD TRACT Specific Plan
~15% of parcelsOriginal 1920s subdivision covering the central flats — has front-yard setback requirements (typically 25 ft vs. LA's 20 ft default) and some lot-shape rules that can constrain ADU footprint placement.
Watch-outs specific to Woodland Hills lots
Patterns we see across Woodland Hills permits and corrections. None of these are dealbreakers — they're just the things people get wrong most often when they don't know the neighborhood.
- 01
Hillside lots need a soils report
If your lot is south of the Boulevard and slopes more than 10%, LADBS will require a geotechnical / soils engineering report before issuing the building permit. Budget $3,000–$8,000 for the report and add 4–8 weeks to your timeline. The cost is recoverable if you build — but the schedule risk is real.
- 02
Pre-1933 garages are common — and conversions get scrutinized
A large share of Woodland Hills homes were built between 1925–1955, and many original detached garages remain. Converting one to a JADU triggers LADBS inspection of the original framing, foundation, and any prior unpermitted work. Plan for a Pre-Inspection (PIRT) and budget for foundation upgrades on anything pre-1950.
- 03
GIRARD TRACT setbacks override defaults
If your address is in the central flats covered by the GIRARD TRACT specific plan, your front-yard setback is 25 ft instead of LA's standard 20 ft. This rarely affects detached rear-yard ADUs but can constrain attached ADUs on narrow lots.
- 04
Transit-corridor parking exemption applies near Ventura Blvd
LA waives the off-street parking requirement for ADUs within ½ mile of a major transit corridor. Most of Woodland Hills within 3–4 blocks of Ventura Blvd qualifies via Metro Local Line 150/240. If your lot's tight, this is a significant unlock.
What you can build in Woodland Hills
Woodland Hills is inside the City of Los Angeles, so LADBS permits apply. Typical zoning in Woodland Hills: R1-1, R1-1-H, RA-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 Woodland Hills ADUs
California has steadily loosened ADU rules since 2017. LA implements these through local ordinance. Here's what currently applies in Woodland Hills:
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.
Read the official text ↗Updated ADU Construction Memorandum
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 Woodland Hills ADUs
›Can I build an ADU in Woodland Hills?
Yes — Woodland Hills is inside the City of Los Angeles, so the same LADBS rules apply as the rest of LA. Most single-family lots in Woodland Hills (zoned R1-1, R1-1-H, RA-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 Woodland Hills?
Typical all-in cost for a permitted detached ADU in Woodland Hills 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. Hillside lots in Woodland Hills run higher — budget +20% on construction plus $3K–$8K for a soils report. Use the cost calculator linked above for a per-lot estimate.
›How long does the ADU permit process take in Woodland Hills?
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. Hillside lots in Woodland Hills typically take 2–4 weeks longer due to the geotech / soils review.
›Do I need a contractor with a specific license for an ADU in Woodland Hills?
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. If your lot is in the Very High Fire Hazard Severity Zone (common in south Woodland Hills), make sure the contractor has worked on VHFHSZ jobs before — the fire-rated assembly requirements are easy to fail inspection on.
›Does Woodland Hills have an HPOZ (historic overlay) I need to worry about?
No — Woodland Hills 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 Woodland Hills?
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. Woodland Hills sees the full benefit since LADBS is the permitting agency.
›Can I rent out the ADU on Airbnb in Woodland Hills?
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. Woodland Hills 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. On hillside Woodland Hills lots, you'll also need a licensed geotech engineer for the soils report.
