About ADUCheck

A free property report and plan library for Los Angeles, from Vivienda.

Anyone with a Los Angeles address can see what they can build: the zone, which kinds of ADU fit, where a detached ADU can go, which fees apply, and the pre-approved plans that fit. Every fact shows its source and the date we read it. Plans are credited to the firms that own them and link to the official listing.

Vivienda builds homes in Los Angeles and works with partner architects, builders, trades and lenders. govivienda.com

Who writes the guides

Guides are written by the Vivienda team and checked against the ADU rules for Los Angeles, the same file the property report is built from, before publishing. Every guide lists its sources and the date we read each one.
