Design, city permits, build — you deal with one team
ADUs, single-family and commercial across San Diego County — drawn, submitted, corrected and approved. We deal with the city so you don’t have to.
Three kinds of project, one permitting team.
ADU
Junior · Attached · DetachedAccessory dwelling units — the fastest route to added square footage and rental income.
Residential
New build · Additions · RemodelsSingle-family work — ground-up construction, additions, second storeys and full remodels.
Commercial
TI · Change of use · New buildTenant improvements and occupancy changes taken through plan check start to finish.
Where projects stall
Plan check is the hard part.
Most delays aren’t construction — they’re corrections. Drawings that don’t anticipate what a reviewer will flag go back around, and every round costs weeks.
Which ADU can I actually build?
Three types, three different rulebooks. The right answer depends on your lot, your existing structure and your jurisdiction.
