The Sacramento region pairs a hot-summer climate with active residential and ADU construction across the capital area.
Title 24 in the Sacramento Region
The region spreads across the Sacramento Valley floor and rises east into the Sierra foothills. Most of it shares hot, dry summers and cool, wet winters, so a Title 24 model here has to handle both a sizeable cooling load and a real heating season. Insulation, window selection and orientation, duct location and heat pump efficiency all matter. Sacramento is also home to the California Energy Commission, which writes and updates the Title 24 energy code.
Sacramento-Area Climate Zones
- Valley floor — Sacramento is in Climate Zone 12.
- Placer County — Roseville, Rocklin and Lincoln are in Climate Zone 11, which the code treats separately from the valley floor.
We also serve Elk Grove, Folsom and Davis. Zone lines do not follow city limits, so the report always uses the zone for your project address and ZIP code. The climate zone map covers all 16 zones.

Frequently Asked Questions
Do Sacramento County and Placer County use different Title 24 rules?
The state energy code is the same in both. Each city or county building department may add local amendments and has its own submittal process, so follow the checklist your department provides.
Which report do I need for a Sacramento duplex?
Multi-unit buildings typically use an LMCC rather than a CF1R. See CF1R vs LMCC.
