Full Breakdown
Menifee Municipal Code Section 9.185.030(A) exempts retaining walls less than 3 feet in height from development review, while noting a building permit may still be required; the City's Code Enforcement Division confirms block walls and retaining walls require a permit. Section 9.185.060(C) requires that an embankment to be retained over 48 inches in height be benched so that no individual retaining wall exceeds 36 inches above finished grade at the low side, with each bench at least 36 inches deep. Taller single retaining walls require engineering review through the Building and Safety Division, and walls combined with fences remain subject to the height limits in Table 9.185.040-1.
