Special Requirements to Know About
Coastal zone projects require a Coastal Development Permit (CDP). If your project is within San Diego's Coastal Overlay Zone, you'll need a CDP in addition to the standard building permit. This adds 2–6 months to your timeline.
ADU regulations are contractor-friendly. Units under 750 sq ft may qualify for fee exemptions, and the city offers pre-approved ADU plan sets.
Title 24 energy compliance is mandatory. Every permit in California requires Title 24 energy compliance documentation.
Pro Tips for Contractors
Use pre-approved ADU plans if possible. The time and cost savings are substantial — 2–3 weeks vs. 4–12 weeks.
Check the Coastal Overlay Zone map early. A project inside vs. outside the zone boundary can mean a 6-month difference in timeline.
