Retaining walls over 4 feet in Yuma require a building permit and engineering plans. The desert soil conditions (caliche, expansive clay) require special design considerations.
Retaining walls exceeding 4 feet in total height (from bottom of footing to top) require a building permit and engineered plans from a licensed Arizona professional engineer. Walls supporting surcharges require permits regardless of height. Yuma's desert soil presents challenges including caliche layers, expansive clay, and settlement issues that must be addressed in design. Proper drainage behind retaining walls is essential to prevent hydrostatic pressure failure. The Building Safety Division reviews retaining wall permits.
Unpermitted retaining walls may result in code enforcement action and potential liability for adjacent property damage.
