Foundation work in Fontana
In Fontana, a lapse of 180 days between inspections voids the building permit. Inspections are regularly scheduled Monday through Thursday only, and you request one at least a day ahead, online at build.fontanaca.gov or on the voice-response line, (909) 350-7693. If the work isn't ready when the inspector arrives, a re-inspection fee may be charged. Building & Safety is at 8353 Sierra Avenue, (909) 350-7640, open 8:00 a.m. to 5:00 p.m.
Monday to Thursday. It's closed every Friday. Specific plan checks may be completed over the counter, the city says, and if you've just bought the property you must provide proof of ownership. Retaining walls have their own rows in the 2025-2026 User Fees: plan check is $65.00 for a City standard wall and $260.00 for an engineered one, and the standard wall's permit is $210.00 for the first 25 linear feet, with $52.00 per additional 50.
Rough grading plan check is $260.00 for the first 10,000 square feet. The issuance fee is $71.00 per permit, and a water heater with its vent is $52.00. Starting January 1, 2026, Engineering reviews new grading plans and issues the permits. A small job is exempt, such as a fill of 50 cubic yards or less on one lot that blocks no drainage course and stays under 2 feet deep. Expect a geotechnical report unless the building official finds it unnecessary, and read the Grading Plan Checking Guidelines on the city's Engineering Grading page.
