Pre-Approved ADU Floor Plans
These Southern California cities publish pre-approved ADU plans — complete plan sets the city has already reviewed for building-code compliance. Because the design and engineering are already done, you don’t have to pay an architect or an engineer — saving you thousands in design fees and several months of time. Permit review drops from months to weeks. Browse the plans below, filter by bedrooms, and when you find one you like, ADU Cities can build it for you — or customize it to fit your lot.
