Local code & loads

Sacramento building code & ASCE 7 design loads

Sacramento 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 Sacramento. Site Class and seismic spectral values may shift based on geotechnical investigation.

Ground snow load0 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.

What's different about Sacramento

Local conditions that affect structural design

City-specific factors that show up in many Sacramento calculation — and the things plan reviewers look for.

Expansive clay and soft, saturated soils near the American and Sacramento Rivers and the Delta often drive foundation and slab design — a geotechnical report is commonly recommended.
Sacramento's large stock of older and mid-century homes means seismic retrofit and load-path upgrades are frequent projects.
California's pro-ADU legislation has made backyard ADUs and garage conversions one of the most common reasons homeowners need stamped structural calculations.
The City of Sacramento has Permit Ready ADU plans available. For more on ADUs see the city's website: https://www.cityofsacramento.gov/community-development/planning/housing/accessory-dwelling-units

FAQ

Structural engineering in Sacramento — FAQs

The questions Sacramento contractors and homeowners ask most often.

Do I need an engineer to remove a wall in my Sacramento home?+
If the wall is load-bearing, structural calculations from an engineer will help avoid comments from the city and streamline the permit process.
Can I apply for a minor permit for a kitchen remodel?+
The City of Sacramento offers minor permits for certain non-structural scope like kitchen remodels. However minor permits are not available if there are alterations to structure, including wall framing. https://www.cityofsacramento.gov/community-development/building/permit-services/minor-permits
How quickly can I get stamped calculations for a Sacramento permit?+
Most residential beam and wall-removal calculations are turned around within a few business days through clearspan's process. Timelines depend on scope, and availability of an engineer to review and accept the design through clearspan.
