Planning a garage conversion in Mission Hills? Mission Hills is one of San Diego’s older neighborhoods, with early-1900s homes, canyon-edge lots, and detached garages. Proactive Edge Developments is a CSLB-licensed San Diego County general contractor. We convert garages end to end, handle the City of San Diego permit process, and include a free 3D rendering so you see the result before we start.
The City of San Diego requires a building permit for every ADU and junior ADU, with no exemptions. Its rules are summarized in Information Bulletin 400. Source: City of San Diego, Information Bulletin 400.
State timeline: when there is already a home on the lot, California law (Gov. Code §66317) requires the city or county to approve or deny a complete ADU application within 60 days.
We prepare the plan set, submit it, answer plan-check corrections, and schedule every inspection through final sign-off.

At 3680–3682 Curlew St in San Diego, we added a second story to the main house and converted the garage into a separate unit. The owner now has two rentable addresses on one lot. It's the project we point Mission Hills homeowners to first, because it shows our permitting, structural, and finish work in one place.
Every new client gets one free 3D rendering, made with our in-house design software — so you see the finished result before a single nail goes in.
Mission Hills projects are permitted by the City of San Diego (Development Services Department). The City of San Diego requires a building permit for every ADU and junior ADU, with no exemptions. Its rules are summarized in Information Bulletin 400.
Under California law (Gov. Code §66317), when there is already a home on the lot, the City of San Diego has to approve or deny a complete ADU application within 60 days. Plan corrections and resubmittals add time, so we give you a written schedule at your estimate.
