Title 24 Reports in San Diego, California
$245 flat fee — delivered in 2 business days. CF1R reports accepted by the City of San Diego Development Services Department and San Diego County.
What’s Required in San Diego
The City of San Diego is served by the Development Services Department. Unincorporated areas of San Diego County are permitted through the San Diego County Planning & Development Services department — a separate agency with its own permit process. We serve both.
Coastal/central San Diego sits in Climate Zone 7 — mild marine climate with low heating and cooling loads, but strict infiltration and window performance requirements. Inland East County communities like El Cajon, Santee, and Ramona fall in Climate Zone 10, with hot summers and greater cooling demands.
The 2025 Title 24 code introduced expanded heat pump requirements for new construction in both zones. CZ 7 projects must meet tight envelope and ventilation standards; CZ 10 projects require higher SEER2-rated equipment, radiant barriers, and low-SHGC glazing.
San Diego has one of the strongest ADU markets in California, driven by state legislation and city-friendly permitting. Active new construction in Chula Vista, National City, Escondido, and unincorporated San Diego County keeps permit volume high year-round.
