Local code & loads
Mesa building code & ASCE 7 design loads
Mesa enforces the 2024 Mesa Building Code, 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 Mesa. Site Class and seismic spectral values may shift based on geotechnical investigation.
| Building code | 2024 Mesa Building Code, based on the 2024 IBC |
|---|---|
| ASCE 7 edition | ASCE 7-22 |
| Seismic Sₛ | 0.19g |
| Seismic S₁ | 0.06g |
| Site class | Default |
| SᴅS | 0.2g |
| Sᴅ₁ | 0.11g |
| Seismic Design Category | B |
| Ultimate wind speed | 102 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.
Mesa is low-seismic, with most sites in Seismic Design Category B, so wind and soils drive design rather than earthquakes. The county's 115 mph design wind covers monsoon microbursts and dust storms. Mesa's soils trend toward variable caliche over collapsible silt deposits that settle when saturated, with localized expansive clay. The values below are regional placeholders only. Always pull site-specific values from the ASCE 7 Hazard Tool (https://ascehazardtool.org) for the actual project address.
