Zip codes:91744917459174691748
**Note:** City of Industry is overwhelmingly industrial by design. Despite covering 12 square miles, the city has only about 200 residents — the daytime working population is roughly 80,000 thanks to its concentration of manufacturing, logistics, and warehouse operations. Accessory Dwelling Unit (ADU) applicability is limited to a small set of residential parcels. If you're researching Accessory Dwelling Unit (ADU) economics in City of Industry, verify your specific parcel is in a residential zone before proceeding. City of Industry is an independent city in the central San Gabriel Valley (SGV), incorporated in 1957 specifically to enable industrial governance. It runs its own building and planning departments. Industry Hills Expo Center, Pacific Palms Resort, and the Workman & Temple Family Homestead Museum (1840s-era adobe) are the most-recognizable destinations.

Frequently asked questions about Industry (City of Industry) ADUs
›Can I build an ADU in Industry (City of Industry)?
Yes. Industry (City of Industry) 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 Industry Community Services, not LADBS — see the ordinance table above for the specific rules.
›How does Industry (City of Industry) differ from LA City for ADU permits?
Three main differences: the permit agency (City of Industry Community Services 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 Industry (City of Industry)?
Median home value in Industry (City of Industry) is around $0.8M, 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 Industry (City of Industry) have pre-approved standard plans like LA's YOU-ADU?
No. Unlike LADBS, Industry (City of Industry) 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.

Yes. The wizard pulls real zoning, overlay, and parcel data for any Los Angeles County address, including Industry (City of Industry).
