One of the most common questions we get from homeowners is: "Do I actually need a permit for this?" The answer is: it depends — and the wrong answer can cost you significantly more than the permit itself.
Here's the straightforward breakdown of what requires a permit in the City of San Diego, what doesn't, and what happens when people skip the process.
Permit Required vs. Not Required
| Project Type | Permit Required? |
|---|---|
| Kitchen remodel (moving plumbing or electrical) | Yes |
| Replacing cabinets only (no electrical/plumbing changes) | No |
| Bathroom remodel (new shower, relocated fixtures) | Yes |
| Replacing a toilet or sink in same location | No |
| Adding a new circuit or subpanel | Yes |
| Replacing existing light fixtures (same circuit) | No |
| Room addition (any size) | Yes |
| ADU (any type) | Yes |
| Structural changes (removing walls, adding beams) | Yes |
| Interior painting, flooring, trim | No |
| Deck over 30" from grade or attached to house | Yes |
| Replacing a water heater | Sometimes |
| Window replacement (same size, no structural change) | No |
| HVAC replacement (same location) | Yes |
When in doubt, pull the permit. The cost of a permit is almost always less than the cost of tearing out finished work because an inspector flags it later — or because you can't sell your house with unpermitted work.
What Happens If You Skip a Permit?
Some contractors will offer to skip permits to save you time or money. This is a red flag. Here's what can go wrong:
Problem 1: You May Have to Demo the Work
If the city discovers unpermitted structural or mechanical work — during a neighbor's complaint, a fire, or any city inspection — they can require you to open walls, remove work, and have it inspected before allowing it to be closed again. This is almost always more expensive than just pulling the permit to begin with.
Problem 2: Insurance Won't Cover It
If a fire or flood involves unpermitted work, your homeowner's insurance may deny the claim. Insurance companies look for unpermitted work as a reason to reduce or deny payouts. This is a real risk people don't think about until it's too late.
Problem 3: It Creates Problems When You Sell
In California, sellers must disclose unpermitted work. Buyers frequently ask their lenders about it — and lenders sometimes won't fund a loan on a home with major unpermitted work. Even if the sale proceeds, you'll likely end up crediting the buyer for the cost of bringing the work into compliance. In our experience, that cost is always higher than what the permit would have been.
How the Permit Process Works in San Diego
- Plans prepared. For most structural or significant mechanical work, your contractor submits plans to the city's Development Services Department.
- Plan check. City reviewers check the plans for code compliance. Simple projects may get over-the-counter approval in a day. Larger projects take 4–12 weeks.
- Permit issued. Once approved, the permit is issued and posted at the job site. Work can begin.
- Inspections during construction. The city inspector visits at key milestones — framing, rough electrical, rough plumbing — before walls are closed.
- Final inspection. When work is complete, a final inspection is called. Upon passing, the permit is closed and the work is on record.
Who pulls the permit matters: Your licensed contractor should always pull the permit in their name with their contractor's license number. When they do, they assume legal responsibility for the work meeting code. If you pull a homeowner's permit for work a contractor is doing, you take on that liability yourself.
