What makes Agoura Hills different
Agoura Hills' ADU ordinance is in Agoura Hills Municipal Code Title 9. The city retains hillside-area rules + design review for ADUs visible from designated scenic corridors. Most of Agoura Hills sits in the VHFHSZ. Plan check is typically 60 days for non-hillside ADUs; hillside parcels add 4-8 weeks for geotech / soils review.

Nearby areas to Agoura 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
Calabasas →
Large lots and high home values make Calabasas an attractive Accessory Dwelling Unit (ADU) market, but Very High Fire Hazard Severity Zone (VHFHSZ) rules and hillside-area restrictions add meaningful cost compared to flat-lot City of Los Angeles builds.
Independent city
Hidden Hills →
Among the most exclusive cities in Los Angeles County. Premium single-family equestrian lots support strong Accessory Dwelling Unit (ADU) economics, but the gated-private nature of the city, conservation overlays, and Very High Fire Hazard Severity Zone (VHFHSZ) rules add real procedural complexity.
LA City
Woodland Hills →
Big lots, R1-1 zoning, and a transit corridor along Ventura make Woodland Hills one of the highest-ADU-permit neighborhoods in LA — but the hillside south of the Boulevard adds real cost.
Frequently asked questions about Agoura Hills ADUs
›Can I build an ADU in Agoura Hills?
Yes. Agoura 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 Agoura Hills Planning Division, not LADBS — see the ordinance table above for the specific rules.
›How does Agoura Hills differ from LA City for ADU permits?
Three main differences: the permit agency (Agoura Hills Planning Division 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 Agoura Hills?
Median home value in Agoura Hills is around $1.4M, 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 Agoura Hills have pre-approved standard plans like LA's YOU-ADU?
No. Unlike LADBS, Agoura 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 Agoura Hills address?
Yes. The wizard pulls real zoning, overlay, and parcel data for any Los Angeles County address, including Agoura Hills. What you'll see today: feasibility for your specific lot, the overlays that apply, and a routing summary pointing at Agoura Hills Planning Division for the permit submittal. Deeper Agoura Hills-specific permit walkthroughs are next on the roadmap as we expand from LADBS into the independent-city ordinances.
