ADUs in Central Los Angeles

Bungalows, duplexes and older homes on compact lots, often with a detached garage at the back: Central Los Angeles is garage-conversion and compact-ADU territory.

What applies to your lot

Building an ADU in Central Los Angeles

Who approves your ADU

City of Los Angeles: plans are checked by LADBS (Department of Building and Safety), and zoning is read on ZIMAS for your parcel. LADBS also runs a Standard Plan Program of pre-approved ADU designs.

Garages at the back of the lot

Many older lots have a detached garage near the rear line. Converting it keeps its existing setbacks and needs no replacement parking.

Compact lots, smart plans

A 400 to 600 sq ft unit with a 4 ft setback often fits where a larger one would not. Our plan books show layouts made for narrow lots.

Historic districts

Some neighborhoods are Historic Preservation Overlay Zones (HPOZ): what is visible from the street may need design review. We check this on ZIMAS first.

FAQ

ADU questions in Central Los Angeles

Who issues the permit in Central Los Angeles?

The City of Los Angeles, through LADBS. We prepare the plans, submit them and follow the plan check until the permit is issued.

Can I convert my old garage?

In most cases yes. A legal garage can become an ADU within its existing footprint, and the city cannot require replacement parking.

Do you come to my property?

Yes. The visit is free: we look at the lot, the access and the utilities, then give you a realistic estimate.
