Foundation work in Pomona
Pomona's Information Handout IH-006, effective August 4, 2026, requires a grading permit for any grading, excavation or earthwork that disturbs 50 cubic yards of soil or more, or whenever the Building Official decides one is needed. Exemptions are the ones in 2025 CBC Appendix J103.2. Plans go straight to the Building & Safety Division and must give exact cut, fill, over-excavation and import quantities in cubic yards. On the fiscal 2026-27 Master Fee Schedule, from a user fee study dated May 21, 2026, a grading permit for 1 to 50 cubic yards is $195.20.
Public Works review of grading is $599.00 per project for 1 to 5 sheets, covering up to 3 reviews. There's no flat fee for block retaining walls of cement masonry units, which are valuation based. The city's standard detail for a 3-foot retaining wall with level backfill, in an April 2026 copy, requires engineering calculations when a wall retains a slope over 4 feet, with height taken from the footing's base, or carries a surcharge.
Liquefaction and earthquake-induced landslide zones each meet Pomona on two CGS quadrangle maps. Your lot could still sit outside both. Census puts Pomona's median year built at 1967. City Hall, 505 S. Garey Ave., houses Building and Safety, which answers 909-620-2311 Monday to Thursday from 7:30 to 6:00 and closes Fridays.
