Our ADU experience in San Diego

SnapADU has built and is in the process of building dozens of ADU projects within the City of San Diego. As such, we know the city’s regulations and processes very well. Turnaround times at the city are improving, with permitting taking 4-6 months in most cases (down from 8-10 months a year ago).

Of note, San Diego promotes the building of more ADUs through the affordable ADU bonus program. Some of San Diego is in the coastal zone, which will add additional time and cost to the permitting process.
