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.

Nearby areas to Paramount
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
Compton →
Affordable lot prices, Metro A Line transit access, and rising land values from regional redevelopment make Compton a value-conscious Accessory Dwelling Unit (ADU) market.
Independent city
Bellflower →
Mid-tier home values plus walkable Bellflower Boulevard commercial district make Bellflower a steady Southeast LA Accessory Dwelling Unit (ADU) market.
Independent city
Lakewood →
Mass-produced 1950s starter homes on consistent lot sizes give Lakewood unusually predictable Accessory Dwelling Unit (ADU) economics. Strong long-term rental demand from the Long Beach + South Bay employment base. Affordable price point relative to coastal South Bay cities.
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.
›Will the PermitPathLA wizard work for my Paramount address?
Yes. The wizard pulls real zoning, overlay, and parcel data for any Los Angeles County address, including Paramount. What you'll see today: feasibility for your specific lot, the overlays that apply, and a routing summary pointing at Paramount Community Development Department for the permit submittal. Deeper Paramount-specific permit walkthroughs are next on the roadmap as we expand from LADBS into the independent-city ordinances.
