Planning a custom home in 4S Ranch? 4S Ranch is a newer planned community in unincorporated San Diego County with HOA-governed neighborhoods. Proactive Edge Developments is a CSLB-licensed San Diego County general contractor. We build custom homes end to end, handle the County of San Diego permit process, and include a free 3D rendering so you see the result before we start.
This area is unincorporated, so permits go through the County of San Diego, not a city. The County publishes free pre-designed ADU plans, and it advises owners to contact the local fire district early, because fire setbacks and sprinkler requirements can shape the design. Source: County of San Diego, County ADU information page.
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 4S Ranch 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.
