Frequently asked questions about Florence-Graham ADUs
›Can I build an ADU in Florence-Graham?
Yes. Florence-Graham 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 Florence-Graham is unincorporated territory rather than a city.
›Why does Florence-Graham use LA County rules instead of LA City rules?
Florence-Graham 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 Florence-Graham 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 Florence-Graham?
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. Florence-Graham-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 Florence-Graham. 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.
