Two Types of Permits
Building Permit
Structural & Major Work
Covers structural changes, additions, remodels, and major renovations. Required when you're changing the layout, load-bearing walls, or footprint of your home.
Usually pulled by: General contractor or homeowner
Trade Permit
Specialty Systems
Covers plumbing, electrical, HVAC/mechanical, and roofing. Required when you're touching water lines, wiring, ductwork, or roof structure. Most remodels need trade permits on top of the building permit.
Usually pulled by: Licensed trade contractor (plumber, electrician, HVAC tech)
Work that typically requires a permit:
• New construction (residential or commercial)
• Additions: garage, deck, porch, ADU, carport
• Expanding or demolishing an existing structure
• Swimming pool installation
• HVAC installation or replacement
• Adding, moving, or removing walls
• Roof installation or replacement
• Finishing a basement
• Solar panel installation
• EV charging station installation
• Generator installation
• Fence installation
• Siding installation
• Window installation or replacement
Work that usually doesn't need a permit:
• Painting interior or exterior walls
• Installing cabinets without changing the layout
• Replacing carpet or flooring
• Replacing fixtures in the same location
• Cosmetic updates (countertops, backsplash, trim)
• Landscaping and yard work
Rules vary by city. When in doubt, call your local building department before starting work.

San Diego charges $180 for the building permit on a $12,000 bathroom remodel. Add the trade permits and you're looking at $624 all in. That number surprises most people because San Diego doesn't use the usual valuation method everyone expects.
San Diego Permit Fees Explained
San Diego uses square footage for most building permits instead of project cost. Table 501A in the IB-501 Fee Schedule sets the rates. A garden-variety bathroom hits $411.02. A $25,000 kitchen runs $411.02. Those compiled benchmarks come straight from the January 2026 tables we pulled.
The city also offers an IB-203 combo permit at $411.02. It covers plumbing, mechanical and electrical for kitchen or bath remodels with no structural changes. No separate plan review. Simple Permits skip plan review entirely for qualifying residential work. We had to cross reference IB-501 and IB-103 to sort this out. The fee schedule PDF buries the combo option on page 3.
Trade permits run separate. Expect $165 for electrical, $115 for plumbing and another $165 for mechanical on a standard job. Add state surcharges based on valuation. Those include the SMIP seismic fee and the $4 per $100,000 building standards fee. Not cheap. Deck projects jump to $1,811 because they trigger full review.
This approach differs from most cities we track. San Diego cares about footprint more than your contractor's bid. If you stay under the thresholds for Simple Permits you save real money. The calculator on this page uses the exact 2026 tables.
Chuck’s Take
“I bid jobs in Missouri where they use straight valuation. San Diego's square foot method throws all that off. A $25,000 kitchen and a $50,000 one can cost the same in permits. Contractors hate surprises like that. Build the $411 combo fee into every bid.”

What Needs a Permit in San Diego?
San Diego requires permits for most structural changes and many replacements. You need one for a new deck. Same for roof replacement, siding work over basic maintenance and basically any electrical panel upgrade. The official infographic from February 2025 lays this out clearly.
Exemptions exist but they stay narrow. Painting, flooring, cabinet installs and maintenance repairs under $1,000 with like materials don't need permits. One story sheds 120 square feet or less slide through. Fences max out at 7 feet and can't sit in certain setbacks. Same size window and door swaps need a permit but skip plan review.
Bathroom and kitchen remodels get tricky. No structural changes and no added fixtures in R-2 or R-3 zones can use the combo permit path. The rules don't bend much beyond that. We pulled the exact list from San Diego Municipal Code Section 129.0203. Don't assume your project qualifies. Check first.
Penalty for Unpermitted Work in San Diego
San Diego doubles your cost if they catch unpermitted work. You pay an investigation fee equal to the original permit fee plus the permit itself. That turns a $411 combo kitchen permit into over $800 real quick.
The building department doesn't play around here. Stop work orders come quick once neighbors complain or inspectors drive by. Selling the house later gets painful too. Title companies flag unpermitted changes every time. We saw this pattern repeat across the California fee schedules we reviewed. Nobody wins when you skip the permit.
How Long Is a Building Permit Good For in San Diego?
San Diego building permits require you to start work within a set window though the exact commencement period isn't listed in the current IB-501. Once started the permit can expire if work stops for too long. Extension requests cost $329.26.
Plan your schedule tightly. The city grants extensions but they don't hand them out forever. File early if you know delays are coming. We couldn't find a clean abandonment period in the latest PDF. Check directly with Development Services before you pull the permit.
Who Should Pull the Permit in San Diego?
California law requires licensed contractors for work over $500. That covers almost every real remodel. The contractor must pull the permit in their name. Homeowners can go owner-builder but only on their chief residence.
If you choose owner-builder you sign the DS-3042 verification form. You take full responsibility for code compliance and inspections. Most contractors we hear from won't touch a job where the homeowner pulls the permit. It creates insurance headaches. If your bid says you pull it yourself treat that as a red flag.
Chuck’s Take
“Never let a homeowner pull the permit on my jobs. I want my license and insurance tied to the work. If a San Diego contractor asks you to sign that DS-3042 form yourself walk away. Decent contractors pull their own permits.”
Leonard “Chuck” Thompson, LC Thompson Construction Co.
San Diego's Combo Permit and Square Footage System
The IB-203 combo permit at exactly $411.02 stands out as San Diego's best deal. One flat base combo permit fee covers electrical, plumbing and mechanical for kitchen or bathroom remodels without structural changes. It covers the trade permit bundle only, so state surcharges, mapping fees, general plan maintenance and any valuation-based surcharges may still apply.
This beats piecing together three separate trade permits in many cases. We saw the same $411 price on both a $15,000 bathroom and a $50,000 kitchen. Square footage rules create that consistency. The system doesn't care if you use premium finishes. It only measures the footprint.
State surcharges still apply on top based on your estimated valuation. Mapping fees and general plan maintenance can appear too. The quirk makes budgeting easier than valuation-based cities but surprises people who expect everything to scale with their project cost. If your remodel stays simple this structure saves time and money. If it gets complex the price climbs fast.
