The San Diego Permit Process Step by Step
- Project scoping and design: Define what you're building. Our architectural team creates compliant drawings.
- Plan preparation: Architectural drawings, structural engineering (if needed), Title 24 energy calculations, and site plans.
- Plan submission: Submit to City of San Diego Development Services Department (DSD) at 1222 First Ave.
- Plan review: DSD reviews for building code, zoning, and fire safety compliance. Expect 2–10 weeks depending on project complexity.
- Corrections (if any): Address reviewer comments and resubmit. Our team handles this without additional cost.
- Permit issuance: Once approved, pay fees and receive your building permit.
- Construction with inspections: Build per approved plans. Schedule inspections at each milestone (foundation, framing, electrical, plumbing, final).
- Final inspection and sign-off: City inspector verifies everything matches approved plans. You receive a Certificate of Occupancy or completion.
Common Permit Mistakes to Avoid
- Starting work without a permit: The City of San Diego can issue stop-work orders, fines up to $5,000, and require you to tear out unpermitted work.
- Hiring unlicensed contractors: Only licensed contractors can pull permits in California. Verify at the CSLB website.
- Skipping engineering: Structural changes require a licensed engineer's stamp. Skipping this leads to plan rejection.
- Ignoring energy code: California Title 24 compliance is mandatory for all new construction and major remodels.
Frequently Asked Questions
How long does it take to get a building permit in San Diego?
Simple permits (electrical, plumbing) take 1–3 weeks. Major construction permits take 4–10 weeks depending on complexity and current DSD workload.
Do I need an architect for a building permit in San Diego?
For structural changes, additions, and ADUs — yes. Simple replacements (like-for-like roofing, water heater swap) don't require architectural drawings.
What happens if I build without a permit in San Diego?
The City can issue fines, stop-work orders, and require you to demolish unpermitted work. Unpermitted construction also creates problems when selling your home — buyers' inspectors and lenders flag it.

Can a homeowner pull their own permit in San Diego?
Yes, homeowner-builders can pull permits for their own residence. However, you must supervise the work yourself and may need to pass exams for specialty trades. Most homeowners find it easier to use a licensed contractor who handles permits as part of the project.
