Local code & loads
Sacramento building code & ASCE 7 design loads
Sacramento 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 Sacramento. 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 | = 0.66g |
| Seismic S₁ | = 0.24g |
| Site class | Default |
| SᴅS | = 0.65g |
| Sᴅ₁ | = 0.24g |
| Seismic Design Category | D |
| Ultimate wind speed | 94 mph |
| Ground snow load | 0 psf on the valley floor (no ground snow at Sacramento's elevation) |
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.
Sacramento sits on the valley floor with low-to-moderate seismicity relative to coastal California, but liquefaction and expansive/soft soils near the rivers and Delta frequently govern foundation design. Always pull site-specific values from the ASCE 7 Hazard Tool (https://ascehazardtool.org) for the actual project address.
