Local code & loads

Merced building code & ASCE 7 design loads

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

Merced is situated in the San Joaquin Valley at the foot of the Sierra Nevada foothills, on the alluvial plain formed by the Merced River and Bear Creek. Seismicity is moderate; the Ortigalita Fault to the west and the fault systems of the central Coast Ranges are the nearest significant sources. Valley alluvial soils are generally competent but can be variable near watercourses

What's different about Merced

Local conditions that affect structural design

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

Merced is the county seat of Merced County and has experienced renewed growth following the opening of UC Merced in 2005; the newest University of California campus, located at the foot of the Sierra Nevada foothills just east of the city. The university has driven population growth, residential construction, and a modest commercial and student-housing development boom that has increased demand for structural engineering services.
The city's existing housing stock includes a large proportion of older single-family homes built in the 1950s–1980s, many of which are candidates for seismic assessment and retrofit when owners undertake major renovations. Newer subdivisions on the city's growing east side have more modern construction, but foundation conditions near Bear Creek and the lower-lying areas can still vary enough to warrant geotechnical review for significant additions.
Merced's Central Valley location means agricultural structural engineering is also part of the local market, though less dominant than in more agriculture-centric communities to the south. Dairying, poultry operations, and row crop infrastructure in Merced County can require structural review for large-span buildings, storage facilities, and equipment foundations.
California's ADU legislation has been embraced in Merced, where older single-family homes often have detached garages and generous lot sizes. Garage conversions and backyard ADUs have become common projects as homeowners seek to generate rental income or house extended family, and stamped structural calculations from a licensed PE are required for all non-pre-approved designs.

Permits

Where to submit your Merced permit

FAQ

Structural engineering in Merced — FAQs

The questions Merced contractors and homeowners ask most often.

Does Merced have specific requirements for ADU construction?+
Merced follows California's streamlined ADU permitting requirements, which significantly limit local restrictions on ADUs. For non-pre-approved or custom designs, PE-stamped structural plans are required. clearspan can connect you with a California-licensed engineer familiar with Central Valley ADU projects.
How does UC Merced's growth affect structural engineering in the area?+
UC Merced's expansion has driven residential and commercial construction on Merced's east side, including multi-family and student-housing projects that require structural engineering. Private development in the surrounding area is where clearspan connects project owners with engineers for both residential and commercial scope.
What building code does Merced use?+
Merced enforces the 2025 California Building Code (CBC), based on the 2024 IBC and ASCE 7-22 for structural loads. The City of Merced Building Division may have local amendments; confirm before submitting permit applications.
