Foundation work in Modesto
Modesto's Building Safety Fees page, on the FY 2025-26 tab of the city's Development Fee Schedule, charges $216.00 an hour for inspection and reinspection. Minor mechanical, plumbing or electrical work is $242.00 per permit. A water heater replacement is $139.00, re-roofing $558.00, and the strong-motion tax $2.00 per valuation. There's no foundation row, so ask Building Safety. Homeowners can apply, pay and get water heater and reroof permits online through the city's Expedited Permits page.
Contractors can also get service-upgrade and HVAC permits 24-7 and schedule inspections online, and minor work is available over the counter. Before permitted work is covered up or built over, request its inspection through the eTRAKiT Online Permits Portal. Over half of the homes here predate 1980: 44.8% of units went up from 1950 to 1979 and 9.9% before that, for a median year built of 1978 (ACS, 2020 to 2024).
No state liquefaction, landslide or fault-rupture zone is drawn in or along Modesto. That isn't a finding about your lot, because those maps exist only where a quadrangle has been studied. For environmental health and groundwater questions, the Stanislaus County Department of Environmental Resources is at 3800 Cornucopia Way, Suite C, (209) 525-6700. Since January 1, 2025, someone without a contractor's license may take a job under $1,000 only if they hire no workers and the job needs no building permit, CSLB says. Unlicensed contracting can bring administrative fines up to $15,000, so don't pay anything until you've looked the license up.

Permits for foundation repair work in Modesto
If Modesto has its own building department, start there and ask who issues permits for foundation, waterproofing and sump work.
