Local programs

City and county pages organize the jurisdiction-specific ADU material represented in the current public dataset.

Accepted listings

Accepted listings are plan-location records. They show where a public source says a plan appears as accepted or pre-approved.

Official sources

Official city, county, state, PDF, and provider-linked source records are kept separate so each detail can be checked before use.

Unsupported cities

Cities without reviewed public source data are not listed here. Submit an official program URL for review when a city is missing.
