Approval Paths
Three Ways to Get ADU Plans Approved in Los Angeles
Every ADU in Los Angeles needs a permitted plan set. The plan you start from changes how long design takes and how much the city reviews.
| Plan path | Design time | City review | Best for |
|---|---|---|---|
| LADBS Standard Plan Program | Plan already drawn; site plan still needed | Faster plan check, since the city pre-reviewed the building | Owners who like one of the city's listed designs |
| ADU Build LA floor plans | 2 to 3 weeks to adapt to your lot | Standard ADU plan check, 8 to 16 weeks | Most lots: proven layouts with a fixed starting price |
| Full custom design | 6 to 12 weeks | Standard ADU plan check, 8 to 16 weeks | Two-story ADUs, hillside lots, or a unique program |
Pre-approved or not, every plan still needs a site plan for your parcel, utility design, and a building permit before construction starts.
