How we build an ADU in San Francisco
Six steps, from the first look at your building to the final inspection.
Step by step

- Design and estimateA floor plan and a written, itemized construction price.
- PermitState Program review within 60 days of a complete application, or the Local Program with its own steps.
- ConstructionFoundation to finishes, with city inspections along the way.
- Final and move-inFinal inspection, sign-off and a walk-through with you.
Choosing the program
We decide between the State and Local Program before design, because it changes how many units you can add, which waivers are available and whether rent control applies.
Inspections
The Department of Building Inspection inspects the work in stages. We schedule them as the job moves.
