Foundation work in Santa Rosa
Grading in Santa Rosa costs $400.75 in plan check and $1,102.06 in inspection under the city fee schedule effective July 1, 2026. Where the row is Grading Permit with NPDES, the two lines are $601.13 and $2,103.94. Walls cost less. An engineered concrete or masonry retaining wall is $100.18 to check the plans and $300.56 to inspect. The same Building Fees list puts a fence, gate or freestanding wall at $50.10 and $150.28.
A Residential Seismic Hazard Inspection is $200.38. It's shown in the inspection column only, with no plan check charge beside it. Most other plan check and permit fees follow the value of the project, the Fees, Permit & Inspection FAQ says. Applications go to the Building Division, part of Development Services under Planning & Economic Development, through Accela Citizen Access. A liquefaction zone and an Alquist-Priolo fault zone each reach the Santa Rosa line on one California Geological Survey quadrangle map, while no earthquake-landslide zone does.
Touching the city line isn't touching your parcel, so have the company that quotes you point to your lot on that quadrangle. CGS rules call for the soil under foundations in such a zone to be checked for stability, with measures against it built into the home's design. For Santa Rosa housing, the median year built is 1980, from the Census survey covering 2020 to 2024.
