Full Breakdown
' A wall taller than 4 feet, or any wall regardless of height that supports a surcharge (extra load behind the wall, such as a driveway, sloped fill or adjacent structure) or holds back flammable or combustible liquids classed I, II or IIIA, needs a permit and engineering review. 130(A). 76's Hillside Planned Development standards and other grading chapters can require retaining walls as a design condition even where the wall itself falls under the 4-foot permit exemption, so a small retaining wall built as part of a graded hillside lot may still need city sign-off through the grading or design review process rather than a building permit.
Violations & Fines
Building a retaining wall over 4 feet without a permit, or one of any height that carries a surcharge or holds Class I, II or IIIA liquids without one, exposes the owner to the same stop-work, correction-notice and re-inspection remedies the Building and Safety Official uses for other unpermitted work under Chapter 20.04, and the wall can be ordered removed or engineered and permitted retroactively before it is allowed to remain.
