- Wall requires a drainage system connected to storm drains
What you need for the permit application:
- Site plan showing wall location and dimensions
- Engineering plans (for walls over 4’ or with surcharges)

Cost: Permit fees $500–$2,000 + engineering $2,000–$5,000

Frequently Asked Questions
Do I need a permit for a patio in San Diego?
Most standard paver patios in San Diego do not require a building permit if they're at ground level and don't involve structural changes, electrical, or plumbing. Raised patios, covered patios with a solid roof, or patios in coastal overlay zones may require permits. Always check with the San Diego Development Services Department for your specific situation.
Do I need a permit for a retaining wall in San Diego?
In San Diego, retaining walls over 3 feet tall (measured from the bottom of the footing) require a building permit. Walls supporting driveways, pools, or structures almost always need permits regardless of height. Walls over 4 feet typically need engineered plans from a licensed structural engineer.
Do I need a permit for a fence in San Diego?
In San Diego, fences under 6 feet in side and rear yards do not require a permit. Front yard fences are limited to 3 feet without a permit. Pool fences must be at least 5 feet tall with self-closing gates. Fences in coastal zones, historic districts, or on retaining walls may require permits.
How much do building permits cost in San Diego?
Building permit costs in San Diego vary by project. Simple over-the-counter permits (electrical outlet, gas line) cost $100–$500. Building permits for retaining walls or structures cost $500–$2,000+. Plan check fees add 65–85% of the permit fee. Expedited processing is available for an additional fee.
How long does the permit process take in San Diego?
Simple over-the-counter permits (gas, electrical) can be issued same-day. Building permits requiring plan check take 4–8 weeks for initial review. Coastal overlay zones can take 3–6 months.
