San Diego is California’s second-largest city, with extensive ADU, residential, and multifamily construction across varied coastal and inland climates.
San Diego sits primarily in Climate Zone 7 — one of California’s mildest zones thanks to its coastal Mediterranean climate. Title 24 requirements here are less heating and cooling intensive than inland zones, but solar PV and heat pump requirements still apply under the 2025 code.
San Diego projects go through the City of San Diego Development Services Department. We format every report for San Diego submission.
We prepare Title 24 reports for all project types in San Diego:
- New single-family home construction
- Room additions of any size
- ADUs and Junior ADUs including garage conversions
- Remodels and alterations affecting insulation, windows, or mechanical systems
- Multifamily duplexes, triplexes, and fourplexes
- HVAC replacement projects
- Window replacement projects
We also serve Chula Vista, Oceanside, El Cajon, Escondido, and all of San Diego County.
