Foundation work in Riverside
A flat $102.50 for plan check and $102.50 for the permit covers a residential foundation repair or Earthquake Brace + Bolt job on Riverside's Building and Safety fee sheet (July 1, 2026). Retaining walls up to 100 linear feet carry the same two charges, with $45.00 for each additional 100 feet. Foundation-only work is 25 percent of the building permit and plan check fee. Public Works grading plan check for 0 to 500 cubic yards starts at $1,280.00, and grading permit issuance is $1,624.00.
The same July 2026 schedule charges $138 for a special inspection of unpermitted activity. The Building & Safety Division issues about 6,000 permits and runs over 50,000 inspections a year, and it posts a Daily Inspection List. Its new Public Permit Portal for booking them online is "coming soon." Until it opens, ask the division how to schedule one. For a retrofit, the CRMP directory lists contractors who've completed special FEMA training on wood-framed houses, searchable by ZIP, name or license number.
CRMP says you or your contractor must get the permit from Building & Safety before work starts. Confirm the license on CSLB's site. Census counts for 2020 to 2024 date 46.4% of Riverside's housing units to 1950 through 1979 and 10.1% to before 1950. The state hasn't mapped a liquefaction, landslide or fault zone reaching the city boundary. That may reflect a quadrangle nobody has zoned yet, and it doesn't rule out a soil problem at your address.
