Summary
Baldwin Park caps retaining walls at 10 feet overall height, with the fill-retaining portion excluded from the standard fence height limits. Any retaining wall over 4 feet from footing to top needs a building permit from the Building Official.
(D) Retaining wall height. A retaining wall containing fill shall comply with the above height requirements, except the height of the wall used to retain the fill shall not contribute to the height of the wall. However, the overall height of the wall, including the retaining portion of the wall, shall not exceed ten feet. ... (5) Retaining walls which are not over four feet (1,219 mm) in height measured from the bottom of the footing to the top of the wall, unless supporting a surcharge or impounding Class I, II or III-A liquids.
Full Breakdown
060(A) through (C), which cap walls at 3 feet in a front yard (5 feet for open wrought iron with pilasters covering no more than 30% of the run), 6 feet in a side or rear yard in residential zones, and 8 feet in commercial and industrial side or rear yards. But the code carves out the retaining function itself: the height of the portion of the wall used to hold back the fill does not count toward those limits. The tradeoff is a hard ceiling on the combined structure.
The overall height of the wall, including the retaining portion, cannot exceed 10 feet under any circumstance in any zone. That means a homeowner grading a sloped lot can build a taller retaining structure than the ordinary fence limit would allow, but only up to the 10-foot combined cap, after which no amount of fill retention buys additional height. 062(A)(5) of the Building Code separately controls when a permit is triggered: a retaining wall is exempt from the building permit requirement only if it is not over 4 feet measured from the bottom of the footing to the top of the wall, and only if it is not supporting a surcharge and not impounding Class I, II or III-A liquids.
A retaining wall over 4 feet, or any retaining wall regardless of height that holds back a surcharge load or liquids, needs a full building permit reviewed by the Building Official before construction. 210 before construction or significant modification can begin.
Violations & Fines
Building without the required permit is enforced through the Building Official's inspection process, and unpermitted retaining wall work can be red-tagged and required to be removed, retrofitted or permitted after the fact with as-built engineering. Because the general penalty at § 10.99 applies code-wide, a code violation carries misdemeanor exposure of up to a $1,000 fine and up to six months in jail, or an infraction track of $100 for a first offense, $200 for a second within a year, and up to $500 for a third; each day a wall remains out of compliance can count as a separate violation.
