ADU Service Areas in Santa Monica and West Los Angeles

Santa Monica Neighborhoods Permitted by the City

North of Montana, Wilshire Montana, Mid-City, Pico, Ocean Park and Sunset Park all sit inside Santa Monica city limits. ADUs there go through the city's Community Development Department, with City Planning applying the ADU standards and Building and Safety running plan check. The rules come from Municipal Code Section 9.31.025, and approval is ministerial.

Within the city, the differences between neighborhoods come from the land and the buildings. North of Montana has the largest lots. Ocean Park has narrow early-1900s parcels and Coastal Zone questions. Sunset Park has small 1940s homes. Pico and Mid-City have many apartment buildings and rent-controlled tenants. Wilshire Montana mixes bungalows, duplexes and condos.

ADUs in the Los Angeles Neighborhoods We Cover

Santa Monica Canyon, Venice, Mar Vista and Sawtelle all belong to the City of Los Angeles. ADUs there are permitted by LADBS under LA's ADU ordinance, and utilities come from LADWP rather than the city of Santa Monica and SCE.

The canyon trips people up the most. It has a Santa Monica 90402 ZIP code, but Adelaide Drive marks the city boundary, and parcels below it are in Los Angeles. Venice adds coastal and specific plan rules. Mar Vista includes a historic preservation overlay zone in the Mar Vista Tract. Sawtelle has many apartment lots suited to multifamily ADUs.

• Santa Monica Canyon: hillside, fire and coastal mapping
• Venice: Coastal Zone and specific plan
• Mar Vista: postwar lots and one HPOZ
• Sawtelle: apartment lots and older houses

How We Confirm the ADU Rules for Your Address

ZIP codes and mailing addresses are not reliable guides to jurisdiction on the Westside. Before we design, we look up the parcel in the correct city's zoning records to confirm which city it is in, its zone, and any overlays such as the Coastal Zone, hillside or fire hazard mapping, or historic status.

That lookup decides which ADU code applies, who reviews the plans, which utility serves the property, and whether extra approvals are needed. Getting it right at the start avoids redrawing plans later.

ADU Types Common Across Our Santa Monica Service Area

Garage conversions are common everywhere we work, because so many Westside lots have an old garage at the rear. Detached cottages are most common where lots are larger, such as North of Montana and parts of Mar Vista. Two-story units over garages suit the tight lots of Ocean Park and Venice. Multifamily ADUs fit the apartment-heavy blocks of Pico, Mid-City and Sawtelle.

Junior ADUs work in any single-family house with a spare room or attached garage. Whichever city has the parcel, the same state baseline holds. New units can sit four feet from side and rear lines, a complete application must be decided within 60 days, and no one can make you live on site.
