Question 1

Which Los Angeles neighborhood builds the most ADUs?

Accepted Answer

North Hollywood leads every neighborhood in the City of Los Angeles with roughly 281 ADU permits in 2025. The rest of the top five are Reseda (197), Van Nuys (192), Granada Hills (164), and Northridge (130). All five are in the San Fernando Valley, where large flat single-family lots and R1 zoning make detached ADUs straightforward to site.

Question 2

Why does the San Fernando Valley dominate LA ADU permits?

Accepted Answer

The Valley has the combination an ADU needs: large, flat, single-family lots zoned R1, existing detached garages that convert cheaply, and rear yards deep enough to place a new detached unit while keeping the four-foot side and rear setbacks state law allows. Denser, hillier, or more expensive parts of the city run into small lots, hillside grading requirements, or overlay zones that add cost and review time. Nine of the ten highest-permitting neighborhoods in the table below are Valley neighborhoods.

Question 3

Are these exact ADU permit counts for each neighborhood?

Accepted Answer

They are close estimates, not exact counts. LADBS publishes permits keyed to ZIP code, and LA ZIP codes do not line up with neighborhood boundaries, so each ZIP's ADU permits are split evenly across the neighborhoods that share it. A neighborhood covered by a single ZIP is effectively exact; one spread across five or more ZIPs carries more smoothing. The zip count for every row is in the downloadable CSV so anyone can judge the uncertainty themselves.

Question 4

Why is the neighborhood total lower than the City of Los Angeles total?

Accepted Answer

This table covers the 101 Los Angeles neighborhoods PermitPathLA maintains area pages for, which is not every neighborhood in the city, so the 4,849 permits shown for 2025 are a subset rather than a city-wide total. The counting rule also differs from the state's: this table counts distinct parcels per year from the LADBS permit feed, while the state's Annual Progress Report counts each permit row. For a city-wide and county-wide figure on the state's definition, see the ADU permits by LA County city table.

Question 5

How do I find out how many ADUs were permitted near me?

Accepted Answer

Find your neighborhood in the table below, or open its PermitPathLA area page, where the same permit count appears alongside that neighborhood's zoning, overlay zones, and typical ADU pathway. If you want the answer for your specific parcel rather than your neighborhood, the free address feasibility check reads the parcel's zoning, lot size, and overlays and returns what is buildable on it.
