The Consequences of Skipping Permits
We hear it all the time: "My neighbor didn't pull a permit and nothing happened." Here's why that's a gamble:
When Selling Your Home
Home inspectors and buyers' agents will check permit records. Unpermitted work must be disclosed in California. Buyers often demand price reductions — or walk away entirely. Some require the seller to obtain permits retroactively, which can involve opening walls for inspection.
Insurance Issues
If a fire or flood originates from unpermitted work, your insurance company may deny the claim.
Fines
If the City discovers unpermitted work (often through neighbor complaints), you'll pay permit fees plus penalties — typically double the original permit cost.
Safety
Permits exist to ensure work meets building codes. Electrical or structural work done incorrectly can kill you. It's not bureaucracy — it's basic safety.
How to Get a Permit in San Diego
- Determine permit type: Over-the-counter (simple projects) vs. plan check (complex projects requiring review)
- Prepare documents: For simple permits, a description of work is enough. Complex projects need architectural plans.
- Submit application: Online via San Diego Development Services portal or in person at their office.
- Pay fees: Typically $150-500 for simple permits; more for major work.
- Complete work: Display permit on-site during construction.
- Schedule inspections: Inspector verifies work meets code.
- Final approval: Permit is closed once all inspections pass.
