California is not the hurricane coast. Most metros sit near the ASCE 7-22 baseline (~95–100 mph). But the wind check is still required on every permit — and five mountain passes spike well above the map.

In most of California, seismic drives the lateral system. Wind still has to be run, documented, and compared — and on some elements wind wins outright.
Across LA, the Bay Area, San Diego, and the Central Valley, the design wind speed sits near the ASCE 7-22 contour.
Wind stops being a formality on specific elements and locations, regardless of the seismic story.
WindLoadCalc computes to ASCE 7-22, the newest and most conservative edition of the wind-load standard.
California's current building code, the 2025 Building Standards Code (Title 24) built on the 2024 IBC, references ASCE 7-22 statewide — the edition WindLoadCalc applies. The calculator outputs basic wind speed, exposure, MWFRS, and C&C zone pressures.
ASCE 7-22 shades mountain passes as Special Wind Regions where terrain funnels wind past the smoothed map. Inside these zones, use the county value — not the contour line.
The gap between the San Bernardino and San Jacinto mountains, funneling marine air into the Coachella Valley. Palm Springs (92262) sits on the edge. Riverside County publishes the design wind speed.
Between the southern Sierra Nevada and the Tehachapi Mountains. Tehachapi (93561) and Mojave (93501) fall inside it. Kern County holds the jurisdictional numbers.
The I-580 corridor from the Bay Area to the Central Valley. Livermore (94550) and Tracy (95376) are affected. Alameda and San Joaquin counties publish values.
The I-15 climb from the LA basin to the High Desert. Hesperia (92344) and Victorville (92392) sit downwind. San Bernardino County is the source.
The fifth shaded set covers Sierra crest and coastal headland areas (Donner, Carson, parts of the Mendocino coast). The calculator flags any SWR ZIP in the output — confirm the value with the local building department.

| Metro / region (sample ZIP) | Risk Cat II speed | California note |
|---|---|---|
| Los Angeles (90015) | ~95 mph | Urban Exposure B. Seismic governs the MWFRS. |
| Beverly Hills (90210) | ~95 mph | Westside baseline; hillside lots may pull Exposure C. |
| San Francisco (94102 / 94110) | ~95 mph | Bay shoreline can shift to Exposure D. |
| Oakland (94612) | ~95 mph | East Bay hills run higher; Hayward Fault nearby. |
| San Jose (95110) | ~95 mph | Santa Clara Valley baseline. |
| San Diego (92101) | ~100 mph | Coastal influence on the shoreline. |
| Sacramento (95814) | ~95 mph | Central Valley baseline. |
| Ventura coast (93001) | ~95 mph | Exposure D on open-water sites. |
| Palm Springs (92262) SWR | ~100 mph map | Special Wind Region: Riverside County may require a higher local value than the map. |
| Tehachapi / Mojave (93561 / 93501) SWR | ~95–120 mph map | Special Wind Region: Kern County publishes the governing local speed. |
| Livermore / Tracy (94550 / 95376) SWR | ~95 mph map | Special Wind Region (Altamont Pass): Alameda / San Joaquin County governs. |
| Hesperia / Victorville (92344 / 92392) SWR | ~100 mph map | Special Wind Region: San Bernardino County publishes the governing value. |
These are references, not design values. Risk Cat III (schools) and Cat IV (hospitals, EOCs) use higher speeds at the same site. For any SWR ZIP, the county value supersedes the contour map.

Yes. Most populated California metros sit near the ASCE 7-22 baseline — about 95 to 100 mph for Risk Category II, depending on the ZIP.
That is far below Gulf and Atlantic hurricane speeds. But lower wind is not zero wind: the building code still requires the calculation on every permitted project, and components and cladding are always wind-governed.
ASCE 7-22 shades five major mountain-pass regions as Special Wind Regions. Banning / San Gorgonio Pass (Palm Springs 92262), Tehachapi Pass (Tehachapi 93561, Mojave 93501), Altamont Pass (Livermore 94550, Tracy 95376), and Cajon Pass (Hesperia 92344, Victorville 92392).
Inside these zones the contour line does not apply — use the county jurisdictional value. The calculator flags these ZIPs in the output.
Downtown Los Angeles (90015) and Beverly Hills (90210) sit around 95 mph for Risk Category II.
San Francisco (94102 / 94110) runs about 95 mph, with the bay shoreline pushing Exposure D. Confirm the exact ZIP-level number in the calculator — micro-terrain and exposure shift it.
WindLoadCalc computes to the latest ASCE 7-22 standard — the most current and conservative edition.
California's current building code, the 2025 Building Standards Code (Title 24) built on the 2024 IBC, references ASCE 7-22 statewide — exactly the edition WindLoadCalc applies. No edition ambiguity in California.
Routine residential and small commercial work needs a California-licensed PE; an out-of-state seal is not accepted as the original.
Hospital projects under HCAI review (formerly OSHPD) and most DSA-reviewed public school projects require a California SE, the higher credential. WindLoadCalc generates the wind calculations and the report; your in-state PE or SE seals it.
No. Our in-house Professional Engineer is licensed in Florida only, up to three stories. We do not provide California PE or SE stamps.
For sealed work in any state, the firm's PE network can route sign-and-seal to a licensee where required — engage that separately from the calculator subscription.
