Foundation work in Santa Ana
A seismic retrofit of an existing raised foundation, done to City of Los Angeles Standard details, qualifies for over-the-counter plan check in Santa Ana, and so do retaining walls without surcharge. The Permit Counter, on the 1st floor of the City Hall Ross Annex, answers at (714) 647-5800. Soils reports are required under CBC Chapter 18, two stamped copies from a California registered geotechnical engineer at submittal. The PCC-06 exemptions sheet (rev. 1/13/2026) skips them for retaining walls holding 6 feet or less of level grade with no surcharge, and for one- and two-story attached additions whose footings reach at least 18 inches below natural grade with four continuous #4 bars.
The building official can still ask for one where the soil or the slope is in doubt. A wall of 4 feet or less from footing bottom to top, with no surcharge, needs Planning Division review but no building permit. Grading plans need a registered civil engineer's signature under Public Works' 2022 guidelines, and any cut of 5 feet or more needs a Cal/OSHA permit. A pre-grading meeting happens on site.
The plumbing worksheet (APP-04, dated 03-11-2026) charges $98.16 per permit in issuance and General Plan surcharge. Liquefaction zones are mapped on 4 state quadrangles that cross or meet the city line, and no fault zone is, though a zone reaching the city doesn't mean it covers your lot. Your purchase disclosure from the seller has to state whether yours is. Book inspections online with the permit number and the PIN printed at the top right of the permit.
