Local code & loads
Rocklin building code & ASCE 7 design loads
Rocklin enforces the 2022 California Building Code (CBC), based on the 2021 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 Rocklin. Site Class and seismic spectral values may shift based on geotechnical investigation.
| Building code | 2022 California Building Code (CBC), based on the 2021 IBC |
|---|---|
| ASCE 7 edition | ASCE 7-22 |
| Seismic Sₛ | = 0.52g |
| Seismic S₁ | = 0.21g |
| Site class | Default |
| SᴅS | = 0.53g |
| Sᴅ₁ | = 0.36g |
| Seismic Design Category | D |
| Ultimate wind speed | = 94 mph |
| Ground snow load | 0 psf (valley-foothill transition elevation; no design snow load) |
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.
Rocklin sits at roughly 241 ft elevation at the valley-foothill transition — no design snow load applies. Decomposed granite and hard rock outcroppings are characteristic of the area; foundation design may need to address shallow bedrock or abrupt soil transitions. Always pull site-specific values from the ASCE 7 Hazard Tool (https://ascehazardtool.org) for the actual project address.
