Local code & loads
Davis building code & ASCE 7 design loads
Davis enforces the 2025 California Building Code (CBC), based on the 2024 IBC. Stamped calculations submitted for permit reference the design parameters below.
Values shown for reference only — project-specific values from the ASCE 7 Hazard Tool should be used for engineering design at the actual project address.
ASCE 7 design parameters
Default values used for most residential and light-commercial projects in Davis. Site Class and seismic spectral values may shift based on geotechnical investigation.
| Building code | 2025 California Building Code (CBC), based on the 2024 IBC |
|---|---|
| ASCE 7 edition | ASCE 7-22 |
| Seismic Sₛ | 0.96g |
| Seismic S₁ | 0.31g |
| Site class | Default |
| SᴅS | 0.85g |
| Sᴅ₁ | 0.54g |
| Seismic Design Category | D |
| Ultimate wind speed | 93 mph |
| Ground snow load | 0 psf |
Risk Category II assumed for typical residential and light commercial use — confirm with your engineer if the occupancy or use may require a higher category.
Davis is a flat university city at roughly 50 ft elevation with relatively lower seismicity compared to Sacramento; the Putah Creek fault is in the area but the Calaveras/Hayward systems are farther west. Heavy clay soils (Yolo clay) are characteristic; expansive soil conditions govern slab and foundation design
