ADU permits in Redondo Beach
Zip codes:9027790278
Redondo Beach is an independent coastal city of about 71,000 people in the South Bay, south of Hermosa Beach. It runs its own building and planning departments. Larger and more residential than Hermosa or Manhattan, Redondo has more variety in lot sizes and a mix of beachfront condos, single-family residential pockets, and the Riviera Village district.

What makes Redondo Beach different
Redondo Beach's ADU ordinance is in Redondo Beach Municipal Code Chapter 10-2. Coastal Development Permit (CDP) requirements only apply to the western strip along the ocean — most of the city is outside the Coastal Zone. Plan check is typically 45-60 days.

Watch-outs specific to Redondo Beach
Patterns we see across Redondo BeachADU permits. None are dealbreakers — they're just the things people get wrong most often.
- 01
Riviera Village hillside lots have grading constraints
South Redondo's Riviera Village climbs Palos Verdes-adjacent hills. Slope-based grading rules + setback enforcement are stricter on these lots.
- 02
Redondo Beach Unified school fees apply
Redondo Beach Unified School District (RBUSD) charges school facility fees on ADUs over 500 sqft.
- 03
Coastal Zone only affects western parcels — check your lot
Most of Redondo Beach is OUTSIDE the Coastal Zone. If your lot is east of PCH, you're likely Coastal-free. Verify with the city's GIS lookup before assuming you need a Coastal Development Permit (CDP).

Premium beachside home values support strong Accessory Dwelling Unit (ADU) economics, but tiny lot widths, Coastal Development Permit (CDP) requirements, and design review on the Strand make Hermosa Beach a procedurally heavy South Bay build.

Premium home values support strong Accessory Dwelling Unit (ADU) economics, but small lots, Coastal Development Permit (CDP) requirements, and design-review overlays make Manhattan Beach one of the more procedurally complex South Bay cities for ADUs.
Frequently asked questions about Redondo Beach ADUs
›Can I build an ADU in Redondo Beach?
Yes. Redondo Beach allows ADUs under its local ordinance, aligned with California Government Code §65852.2 (the state baseline that preempts overly-strict local rules). Most single-family lots can host one ADU plus one JADU. Permits go through Redondo Beach Community Development Department, not LADBS — see the ordinance table above for the specific rules.
›How does Redondo Beach differ from LA City for ADU permits?
Three main differences: the permit agency (Redondo Beach Community Development Department vs. LADBS), the local ordinance details (each city has some flexibility above the state baseline), and the timeline (some cities are faster, some slower than LA's 60-day plan check). See the ordinance breakdown above for the specifics on each.
›How much does it cost to build an ADU in Redondo Beach?
Median home value in Redondo Beach is around $1.5M, which usually means lot economics support a quality ADU build of $200K–$400K all-in. Hillside, coastal, or VHFHSZ lots add 7–25% on top. HCD-prefab units (Connect Homes, Cover, Plant Prefab) bypass local plan check entirely and typically run $190K–$350K turnkey.
›Does Redondo Beach have pre-approved standard plans like LA's YOU-ADU?
No. Unlike LADBS, Redondo Beach does not maintain a city-specific pre-approved plan library. The two faster paths are an HCD-approved prefab (factory-certified, skips local plan check) or a custom designer drawing for your lot. The slower path is a fully custom architect-led design.
›Will the PermitPathLA wizard work for my Redondo Beach address?
Yes. The wizard pulls real zoning, overlay, and parcel data for any Los Angeles County address, including Redondo Beach. What you'll see today: feasibility for your specific lot, the overlays that apply, and a routing summary pointing at Redondo Beach Community Development Department for the permit submittal. Deeper Redondo Beach-specific permit walkthroughs are next on the roadmap as we expand from LADBS into the independent-city ordinances.
