Local code & loads

Henderson building code & ASCE 7 design loads

Henderson enforces the Southern Nevada Amendments to the 2024 International Building Code (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 Henderson. Site Class and seismic spectral values may shift based on geotechnical investigation.

Building code	Southern Nevada Amendments to the 2024 International Building Code (IBC)
ASCE 7 edition	ASCE 7-22
Seismic Sₛ	0.51g
Seismic S₁	0.16g
Site class	Default
SᴅS	0.46g
Sᴅ₁	0.28g
Seismic Design Category	D
Ultimate wind speed	98 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.

Henderson shares the valley's Seismic Design Category D setting and the same demanding soils: loose sand over hard caliche, with collapsible alluvial-fan soils in places that can settle when they get wet. Localized expansive clays show up too. 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 Henderson

Local conditions that affect structural design

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

Henderson is a fast-growing community, and backyard casitas have become one of the more common reasons homeowners look for stamped structural calculations. Recent Nevada legislation has made the casita path easier in many cases.

Like the rest of the valley, Henderson sits over caliche and, in places, collapsible alluvial-fan soils that settle when saturated. A geotechnical report is the usual way to confirm what a lot needs for footings and slabs.

Flood washes and retention basins run through parts of the city. Properties in a FEMA flood zone may have drainage and finished floor requirements that affect the structure.

Seismic Design Category D applies here, so even though the valley is calmer than coastal California, lateral design and solid connections still carry weight.

Permits

Where to submit your Henderson permit

Stamped calculations from clearspan are submitted directly to the City of Henderson Development Services Center. Most residential structural submittals are reviewed online.

Submittal notes

Henderson's Development Services Center handles permits inside the city and coordinates code adoption with Clark County and the other valley cities. Plan review pulls in several city departments, so complex projects can take longer. Confirm the jurisdiction for the project address before submitting.

FAQ

Structural engineering in Henderson — FAQs

The questions Henderson contractors and homeowners ask most often.

Do I need an engineer to remove a wall in my Henderson home?+

If the wall is load-bearing, stamped structural calculations from an engineer will help you avoid plan-review comments and keep the Henderson permit moving.

Does a backyard casita in Henderson need stamped structural calculations?+

Most detached casitas and ADUs include engineered framing and foundation calculations in the permit set. An engineer through clearspan can provide the sealed calcs, and the valley's soils often mean a geotechnical report goes along with them.

How quickly can I get stamped calculations for a Henderson 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.
