Retaining Walls: Encinitas vs San Diego

Retaining walls over 4 feet in height require a building permit with engineered structural plans. Walls under 4 feet are generally exempt but must comply with setback and grading requirements. Walls supporting surcharge loads may need permits regardless of height.

What about retaining walls on coastal bluffs in Encinitas?

Properties on coastal bluffs are subject to the Bluff and Hillside Overlay Zone with additional setback, design, and environmental requirements. A Coastal Development Permit is typically required. Contact Development Services at (760) 633-2710 for bluff property requirements.

Can I build terraced retaining walls to avoid the permit requirement?

Terraced walls in a series are typically measured from the lowest grade to the highest point for permitting purposes. This means multiple shorter walls may still trigger permit requirements if the total height exceeds 4 feet.

Only if each tier is under 3 feet and the tiers are spaced at least the height of the taller wall apart. Otherwise they are measured as a single wall.
