Yes. Almost all major construction—including ADUs, garage conversions, custom homes, and extensive retaining walls—requires strict San Diego County permitting. Bernal Builders handles the entire permitting and engineering process on your behalf to keep your project compliant, legal, and on schedule.
Alpine's rugged terrain often requires extensive site preparation before vertical construction can begin. This typically includes land clearing, heavy excavation, precision grading for proper water drainage, and sometimes specialized structural engineering for hillside foundations.
A full custom home build generally takes 10 to 14 months from the start of site preparation to the final walkthrough. Your exact timeline will depend heavily on the initial permit approval phase, seasonal weather conditions, and the complexity of your property's specific land development needs.
You need a general contractor with proven experience in San Diego's backcountry and rural terrain. They must intimately understand local grading ordinances, possess a strong portfolio of heavy architectural builds, and prioritize transparent communication.
