Zip codes:9022090221902229022390224
Compton is an independent city of about 95,000 people in the South Bay, between Carson and South Gate. It runs its own building and planning departments. Compton holds outsized cultural significance globally as a center of hip-hop history (N.W.A, Kendrick Lamar) and continues to be a major hub of Black + Latino cultural identity in Los Angeles County. The Compton Cowboys urban equestrian community preserves the city's lesser-known horse-keeping heritage.

| Max ADU height | 16 ft / 18 ft with second-story setbacks |
| Setbacks | 4 ft side / 4 ft rear (state minimum) |

Frequently asked questions about Compton ADUs
›Can I build an ADU in Compton?
Yes. Compton 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 Compton Building & Safety Division, not LADBS — see the ordinance table above for the specific rules.
›How does Compton differ from LA City for ADU permits?
Three main differences: the permit agency (Compton Building & Safety 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 Compton?
Median home value in Compton is around $0.6M, 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 Compton have pre-approved standard plans like LA's YOU-ADU?
No. Unlike LADBS, Compton 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 Compton address?
Yes. The wizard pulls real zoning, overlay, and parcel data for any Los Angeles County address, including Compton. What you'll see today: feasibility for your specific lot, the overlays that apply, and a routing summary pointing at Compton Building & Safety Division for the permit submittal. Deeper Compton-specific permit walkthroughs are next on the roadmap as we expand from LADBS into the independent-city ordinances.
