Santa Rosa is the largest city in Sonoma County and the North Bay, with steady residential and ADU activity in a mild climate.
Santa Rosa sits in Climate Zone 3 — a mild coastal climate with cool summers and moderate winters, where window performance and insulation are the primary factors in your energy model. We model every Santa Rosa project using CEC-approved software calibrated to Climate Zone 3.
Title 24 reports for Santa Rosa city projects are submitted to the City of Santa Rosa building department. Sonoma County projects go through Sonoma County. We serve both and format every report for the correct local jurisdiction.
We prepare Title 24 reports for all project types in Santa Rosa:
- 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

We also serve Petaluma, Rohnert Park, Novato, Napa, and the surrounding area.
