Corona FAQ
Menifee FAQ
Do I need a permit for a retaining wall in Menifee?
Yes if the wall exceeds 4 feet from bottom of footing to top of wall, or any height if it supports a surcharge (slope, vehicle, or structural load). Smaller decorative walls without surcharge generally do not need a permit, but always verify with Building & Safety.
Does a retaining wall count toward my fence height?
Often yes. Menifee Development Code Section 9.185 governs how combined retaining-plus-fence height is measured, particularly where the retaining face is visible from the adjoining property. Check 9.185.040 and 9.185.050 for measurement rules.
Who inspects retaining wall construction?
Menifee Building & Safety inspects foundations, reinforcement, and backfill at standard inspection stages. Engineered walls also require special inspections per the structural engineer's plans.
