ADU permits in Del Rey
Del Rey is the LA City neighborhood between Culver City and Marina del Rey, anchored to the south by the Playa Vista tech corridor. Most single-family homes are 1950s post-war tract ranches on uniform 5,400 sqft lots — younger and more uniform than the pre-war Westside neighborhoods. Tech-corridor rental demand makes ADU pro-formas pencil unusually well here.

Permit overlays active in Del Rey
LA City zoning and regulatory overlays that hit a meaningful share of Del Rey parcels. Each one affects what you can build, how long it takes, or how much it costs.
Playa Vista + tech-corridor adjacency
~50% of parcelsDel Rey borders Playa Vista (Google, YouTube, Facebook offices) to the south. Rental demand from tech professionals supports premium ADU rents — 15-20% above the LA median for comparable units. Owner-occupied ADUs for tech workers' parents / au-pair housing are a common use case.
Post-WWII tract housing stock
~80% of parcelsMost Del Rey single-family homes were built between 1947-1955 as small (900-1,400 sqft) stucco ranches on uniform 50x100 lots. The housing stock is more uniform than other Westside neighborhoods — and the original detached garages are good candidates for conversion since they're typically 1950s framing (less archaic than pre-war Fairfax).
Coastal Zone proximity (not within)
~5% of parcelsDel Rey is NOT in the Coastal Zone (the boundary runs along Lincoln Boulevard to the west). Adjacent neighborhoods Marina del Rey and Playa del Rey ARE in the Coastal Zone with significantly stricter permit requirements. Confirm via ZIMAS before assuming Coastal-Zone-style restrictions apply.
Watch-outs specific to Del Rey lots
Patterns we see across Del Reypermits and corrections. None are dealbreakers. They're the things people get wrong most often when they don't know the neighborhood.
- 01
Don't confuse Del Rey with Marina del Rey or Playa del Rey
Three neighborhoods share the 'Del Rey' name and are commonly mixed up. Del Rey is LA City (LADBS jurisdiction, no Coastal Zone). Marina del Rey is unincorporated LA County (different department, different rules, no ADUs under most R-zones). Playa del Rey is LA City but IS in the Coastal Zone (adds California Coastal Commission review). The wrong assumption here costs months of re-application work.
- 02
1950s tract garages convert cleanly
Del Rey's housing stock is younger than Fairfax / Hancock Park — most homes are 1947-1955 ranches with post-WWII framed detached garages. The framing is conventional dimensional lumber, foundations are typical raised slab-on-grade, and electrical was installed in the modern era. Garage conversions here are among the cheapest in LA: $80K-$130K all-in is achievable vs. $150K+ in pre-war neighborhoods.
- 03
Tech-corridor rental premium supports faster ROI
Playa Vista's tech employer cluster (Google, YouTube, Facebook, plus the 'Silicon Beach' VC ecosystem) drives consistently higher rents in Del Rey than equivalent-stock neighborhoods. A 750 sqft Del Rey ADU rents for $2,800-$3,400/month vs. ~$2,400/month in equivalent Reseda. Run your pro-forma with real local comps from Zillow/Realtor, not citywide medians.
- 04
Lincoln Boulevard noise on edge lots
Properties within 200 feet of Lincoln Boulevard face traffic noise that triggers upgraded window assemblies (STC 35+) on new habitable structures per LADBS plan-check. The cost premium is $2K-$5K for ADUs that face Lincoln. Site the ADU at the back of the lot when possible.
What you can build in Del Rey
Del Rey is inside the City of Los Angeles, so LADBS permits apply. Typical zoning in Del Rey: R1-1, R2-1. 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 plus one JADU on the same single-family lot is allowed under LA's current rules. This 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 Del Rey ADUs
California has steadily loosened ADU rules since 2017. LA implements these through local ordinance. Here's what currently applies in Del Rey:
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.
What's changing in LA permit policy
Recent LADBS bulletins, City Council motions, and ordinances that affect what you can build (and how easily) in Del Rey. Updated quarterly from public LA city records.
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 Del Rey ADUs
›Can I build an ADU in Del Rey?
Yes. Del Rey is inside the City of Los Angeles, so the same LADBS rules apply as the rest of LA. Most single-family lots in Del Rey (zoned R1-1, R2-1) 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 Del Rey?
Typical all-in cost for a permitted detached ADU in Del Rey runs $150,000 to $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 to $350K. Use the cost calculator linked above for a per-lot estimate.
›How long does the ADU permit process take in Del Rey?
LADBS aims for 60-day plan check on ADU permits, with same-day issuance if you use a pre-approved standard plan (YOU-ADU or a licensed designer plan). In practice, custom plans average 4 to 7 months from submittal to building permit. Flat-lot Del Rey permits are usually on the faster end of that range.
›Do I need a contractor with a specific license for an ADU in Del Rey?
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 Del Rey have an HPOZ (historic overlay) I need to worry about?
No. Del Rey 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.
›Do the new CA ADU laws apply in Del Rey?
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. Del Rey sees the full benefit since LADBS is the permitting agency.
›Can I rent out the ADU on Airbnb in Del Rey?
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. Del Rey 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.
