ADU permits in Paramount

Zip codes:90723

Paramount is an independent city of about 54,000 people in southeast Los Angeles County, between Compton and Bellflower. It runs its own building and planning departments. The city has unusual agricultural + dairy history — it was a major California hay-distribution hub through the mid-20th century, and Paramount Iceland (the city's roller-rink + ice-rink) has operated since 1939 as a community fixture.

Independent city — not LADBS

Paramount runs its own building department. Permits go through Paramount Community Development Department, not the Los Angeles Department of Building and Safety (LADBS). Our address checker pulls real zoning + overlay data for any Los Angeles County address. The Paramount ordinance breakdown below covers the city-specific permit path.

Frequently asked questions about Paramount ADUs

Can I build an ADU in Paramount?

Yes. Paramount 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 Paramount Community Development Department, not LADBS — see the ordinance table above for the specific rules.

How does Paramount differ from LA City for ADU permits?

Three main differences: the permit agency (Paramount 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 Paramount?

Median home value in Paramount is around $0.7M, 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 Paramount have pre-approved standard plans like LA's YOU-ADU?

No. Unlike LADBS, Paramount 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.
