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.

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.

What's different about Mesa

Local conditions that affect structural design

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

Mesa's soils lean toward variable caliche over collapsible silt deposits. Those collapsible soils can settle when they get wet, so controlled fill, moisture conditioning, and a geotechnical report are common on foundation work.
Natural washes cross many Mesa properties, and monsoon storms can send flash floods through them. Building inside a floodplain easement is restricted, and structures near a wash may need finished floor elevations set above the flood level.
Earthquakes are a minor factor here, so design usually comes down to gravity loads and the 115 mph monsoon wind, with attention to roof anchorage and patio-cover connections.
Many Mesa homes date from the 1990s and 2000s, and adding a second story or a large opening means an engineer has to confirm the existing foundation and framing can carry the new loads.
Extreme summer heat is hard on materials over time, so durable detailing is part of designing exposed structures and connections.

Permits

Where to submit your Mesa permit

Stamped calculations from clearspan are submitted directly to the City of Mesa Development Services, Building Division. Most residential structural submittals are reviewed online.

Submittal notes

Mesa's Building Division handles permits inside the city, with electronic plan review available. Mesa runs its own building code edition, which can differ from neighboring cities, so confirm which jurisdiction covers the project address before submitting.

FAQ

Structural engineering in Mesa — FAQs

The questions Mesa contractors and homeowners ask most often.

Do I need an engineer to remove a wall in my Mesa home?+
If the wall is load-bearing, stamped structural calculations from an engineer will help you avoid plan-review comments and keep the Mesa permit moving.
Does a wash on my Mesa property affect what I can build?+
It can. Structures generally cannot go inside a floodplain easement, and building near a wash may require finished floor elevations above the flood level plus freeboard. An engineer and the city's drainage requirements will shape where and how the structure can sit.
How quickly can I get stamped calculations for a Mesa 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.
