ADU permits in Rolling Hills
Zip codes:90274
Rolling Hills is a small, gated independent city of about 1,500 people on the Palos Verdes Peninsula. It runs its own small civic office; planning and building services are contracted to outside firms given the city's small size. The entire city is a private gated community with 1+ acre lots and a strict equestrian + rural-residential character. Rolling Hills is consistently among the most exclusive cities in California.

What makes Rolling Hills different
Rolling Hills's ADU ordinance is in Rolling Hills Municipal Code Title 17. State preemption forced state-baseline alignment in 2020, but the city retains aggressive design review. The entire city is in the VHFHSZ.

Nearby areas to Rolling Hills
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.
Independent city
Rolling Hills Estates →
Premium hillside home values, equestrian-zoned neighborhoods, top-ranked Palos Verdes Peninsula Unified School District (PVPUSD), and rural-residential character make Rolling Hills Estates an attractive premium Accessory Dwelling Unit (ADU) market.
Independent city
Rancho Palos Verdes →
Premium ocean-view home values support strong Accessory Dwelling Unit (ADU) economics, but California Coastal Zone requirements, hillside grading, Very High Fire Hazard Severity Zone (VHFHSZ) rules, and the actively-moving Portuguese Bend Landslide Complex make Rancho Palos Verdes one of the more procedurally heavy cities in Los Angeles County.
Frequently asked questions about Rolling Hills ADUs
›Can I build an ADU in Rolling Hills?
Yes. Rolling Hills 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 City of Rolling Hills, not LADBS — see the ordinance table above for the specific rules.
›How does Rolling Hills differ from LA City for ADU permits?
Three main differences: the permit agency (City of Rolling Hills 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 Rolling Hills?
Median home value in Rolling Hills is around $4.5M, 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 Rolling Hills have pre-approved standard plans like LA's YOU-ADU?
No. Unlike LADBS, Rolling Hills 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 Rolling Hills address?
Yes. The wizard pulls real zoning, overlay, and parcel data for any Los Angeles County address, including Rolling Hills. What you'll see today: feasibility for your specific lot, the overlays that apply, and a routing summary pointing at City of Rolling Hills for the permit submittal.
