Local code & loads
Bakersfield building code & ASCE 7 design loads
Bakersfield 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 Bakersfield. 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 | 1.09g |
| Seismic S₁ | 0.34g |
| Site class | Default |
| SᴅS | 0.93g |
| Sᴅ₁ | 0.59g |
| Seismic Design Category | D |
| Ultimate wind speed | 94 mph |
| Ground snow load | 0 psf (Bakersfield at ≈410 ft elevation; no design snow load at city elevations; foothills to the east begin to accumulate snow) |
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.
Bakersfield is the largest city in the southern San Joaquin Valley and the seat of Kern County. The region has significantly higher seismicity than the northern Central Valley: the White Wolf Fault (source of the 1952 M7.5 Kern County earthquake; one of the largest California earthquakes of the 20th century) lies about 30 miles to the north; the Garlock Fault crosses east of the city; and the San Andreas Fault runs along the western mountains roughly 45 miles to the west. Additionally, Bakersfield sits atop one of the nation's most productive oil fields, and soil conditions in some areas may be affected by decades of subsurface fluid extraction
