Two Types of Permits
San Diego issues building permits for structural work and separate trade permits for plumbing, electrical, HVAC, and roofing. Most remodels need both kinds. See the full breakdown of which projects need a permit and which are exempt.

San Diego has no valuation-based building permit fee. A bathroom or kitchen remodel with no wall or fixture changes books under a $440.82 combination permit, about $460 with the state fees. That number surprises most people because San Diego prices by item and square footage, not by what the job costs.
San Diego Permit Fees Explained
San Diego has no valuation table for building permits. Table 501A in the IB-501 fee schedule (August 2026) prices new construction, additions and remodels by square footage, and Table 501C prices individual items like decks, siding and windows. A bathroom or kitchen remodel with no wall or fixture changes skips both and takes a single combination permit instead.
That combination permit costs $440.82 per dwelling unit (IB-103 Table 3A, the path IB-203 describes). It covers plumbing, mechanical and electrical for a kitchen or bath remodel with no changes to structural elements, wall framing or exterior walls and no added fixtures. No plan review. With the state seismic fee and the $17.11 fee-collection charge, a $15,000 bathroom comes to $459.88 and a $25,000 kitchen to $461.18.
Single trade jobs run on IB-103 line items. A water heater is $122.97, a panel upgrade up to 200 amps is $176.57 and a central AC condensing unit is $131.52, each plus the state and collection fees. Deck projects cost far more because they go through plan review: $1,677.99 plan check and $264.25 inspection, plus the $737 General Plan Maintenance fee, the mapping fee and a 2.5-hour impact-fee plan check. A typical deck lands at $3,152.53.
This approach differs from most cities we track. San Diego cares about the item and its footprint more than your contractor's bid. If your job qualifies for a Simple Permit you skip plan review and the fees that come with it. The calculator on this page uses the current 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 combo fee, about four sixty with the state fees, into every bid."
Leonard "Chuck" Thompson, LC Thompson Construction Co.
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 siding work over basic maintenance and basically any electrical panel upgrade. A straight roof-covering swap is the exception: San Diego does not require a permit for a like-for-like reroof unless the work reaches the roof structure or decking. 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 in existing openings need no building permit at all (SDMC 129.0203(a)(21)).
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 $460 combination kitchen permit into over $900 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. A permit extension costs $353.13.
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 combination permit at $440.82 (IB-103 Table 3A, the IB-203 path) 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. The permit fee is the same $440.82 on a $15,000 bathroom and a $50,000 kitchen; only the small state seismic fee moves with the job cost. 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.
