Summary
Palm Springs exempts short retaining walls from a building permit under Municipal Code § 8.04.015, amending CBC § 105.2. A retaining wall not over 3 feet high, measured from the bottom of the footing to the top of the wall, needs no permit unless it holds back a surcharge or impounds flammable or combustible liquids. Taller walls, or any wall carrying a surcharge load, require a full building permit.
105.2. Work exempt from permit. Building:
4. Retaining walls that are not over 3 feet in height measured from the bottom of the footing to the top of the wall, unless supporting a surcharge or impounding flammable or combustible liquids.

Full Breakdown
015. 2 measures a retaining wall's height the same way the state code does: from the bottom of the footing to the top of the wall, not from finished grade, so a wall with a deep footing can end up taller overall than 3 feet while still qualifying for the exemption on its measured height. The exemption breaks in two situations even under 3 feet: a wall supporting a surcharge, meaning it retains an additional load beyond the soil itself such as a slope, a driveway, a structure, or parked vehicles above it, or a wall impounding flammable or combustible liquids.
Either condition pulls the wall back into the full building permit process regardless of height, which means engineered plans stamped by a licensed engineer given the added load. Because retaining walls interact with grading, a wall built as part of a larger grading operation can also fall under Appendix J, Grading, where § J101 designates the City Engineer, or a designee, as the building official for administration and enforcement of grading work, a separate approval track from the standard building permit process for a stand-alone wall.
Violations & Fines
Building a retaining wall over 3 feet, or a shorter wall that supports a surcharge or impounds flammable or combustible liquids, without a permit exposes the owner to code enforcement by the Department of Building and Safety, which can order the work stopped, the wall engineered and retroactively permitted, or removed if it cannot be brought into compliance. An unpermitted wall that later fails or shifts soil onto a neighboring lot also carries direct liability exposure separate from the permit violation itself.
