ADU permits in City Terrace

Zip codes:90063

City Terrace is an unincorporated community of about 12,000 people in the hillside east of Boyle Heights, between East LA (proper) and the Whittier Narrows. It is not a city — building permits go through Los Angeles County Public Works (Building & Safety) under LA County Code Title 22. City Terrace sits on a series of hillside ridges with views back to downtown Los Angeles; the community has a strong Mexican-American cultural identity continuous with adjacent Boyle Heights and East LA.

Frequently asked questions about City Terrace ADUs

Can I build an ADU in City Terrace?

Yes. City Terrace allows ADUs under LA County Code Title 22, aligned with California Gov Code §65852.2. Most single-family lots can host one ADU plus one JADU. Permits go through LA County Public Works (Building & Safety) — not LADBS, since City Terrace is unincorporated territory rather than a city.

Why does City Terrace use LA County rules instead of LA City rules?

City Terrace is unincorporated — it's never been formally incorporated as its own city, so LA County serves as the local government. Building permits, zoning, sheriff, libraries (in many cases), and most other services run through county departments rather than city ones.

Where do I submit my City Terrace ADU permit?

Online via LA County's EPIC-LA portal, or in-person at the LA County Public Works Building & Safety counter in Alhambra (900 S. Fremont Avenue). The EPIC-LA online portal handles most ADU submittals end-to-end — you rarely need to visit in person.

How long does the ADU permit process take in City Terrace?

LA County DPW targets the state-required 60-day plan check for ADUs from a complete submittal. Hillside, VHFHSZ, or environmental-review parcels can extend timelines by 4–12 weeks. City Terrace-specific overlays may add additional time — see the watch-outs above.

Are LA County's pre-approved ADU plans free?

Yes. LA County maintains three pre-approved standard ADU plans (Plans A, B, and C) usable in any unincorporated area, including City Terrace. They're free to use, similar to LADBS's YOU-ADU program. The trade-off is reduced design flexibility — but for a fast, low-cost permit path, they're the strongest option.
