Chula Vista FAQ
Do I need a permit for a retaining wall in Chula Vista?
Retaining walls over 4 feet high (measured from footing bottom to wall top) require a building permit with engineered plans. Walls 4 feet or less are generally exempt.
Can I put a fence on top of a retaining wall?

Encinitas FAQ
Do I need a permit for a retaining wall in Encinitas?
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.
