Do I need a permit to remodel a kitchen or bathroom in San Diego?

The short version

In the City of San Diego, a kitchen or bathroom remodel needs a permit when it adds or moves plumbing fixtures, adds electrical circuits, changes walls or framing, or changes a window or door opening. It does not need a permit when it is finish work: painting, flooring, cabinets and counters in the same layout, or replacing a faucet, toilet, showerhead, light fixture or appliance in place. Remodels that touch plumbing or wiring but leave the structure and fixture count alone can use the city’s No-Plan Building Permit.

That is the whole answer for most kitchens and bathrooms, and it comes straight from Municipal Code section 129.0203, the city’s own “When is a Permit Required?” sheet, and Information Bulletin 203. Everything below is the detail: the exact exemption list with its thresholds, where the line sits on plumbing and electrical, how the no-plan permit works, what the fees look like in the 2026 schedule, what happens to a permit you let sit, and why unpermitted work is a problem the day you sell. The unincorporated county runs a parallel list, covered near the end.

One framing note. People ask “do I need a permit to remodel my bathroom” hoping the answer is no. The honest answer is that the permit is rarely the expensive part; the rework after a failed inspection, or the disclosure line at sale, is. We pull permits on every job that needs one, and we would rather explain why than talk anyone out of it.

What is exempt, with the exact thresholds

Section 129.0203 of the San Diego Municipal Code exempts painting and decorating, installation of floor covering, cabinet work and outside paving from a building permit with no limit on value. Other like-for-like maintenance repairs are exempt up to $1,000 in aggregate value, provided they do not affect any electrical or mechanical installation.

The rest of the list, as published in the code (7-2026 edition), with the numbers that matter to a homeowner:

• One-story detached sheds, playhouses and similar accessory buildings with a projected roof area of 120 square feet or less.
• Fences 7 feet or less, other than pool barriers. The city’s sheet adds that fences over 6 feet are prohibited in the front yard setback and over 3 feet in visibility areas, which is a zoning rule, not a permit rule.
• Retaining walls 3 feet or less, measured from the top of the footing, unless they hold a surcharge.
• Decks under 200 square feet, no more than 30 inches above grade at any point, not attached to the house, and not serving the required exit door.
• Patio covers on single family lots in RS and RX zones: 300 square feet or less of roof area, 12 feet or less above grade, not encroaching into a yard, and not in the appealable area of the Coastal Overlay Zone or a Planned Development.
• Re-roofing where the roof structure and diaphragm are not altered.
• Prefabricated above-ground pools of 5,000 gallons or less. Every in-ground pool needs a permit.
• Replacement windows and exterior doors in existing openings, covered in detail below.

Two carve-outs sit on top of the whole list. None of the exemptions apply to work on a designated historic resource or on environmentally sensitive lands, and subsection (b) says the building permit exemptions are not exemptions from electrical, plumbing and mechanical permits. That second sentence is the one that catches kitchens and baths.

Where the line sits in a kitchen

A kitchen remodel that keeps the layout can be done without a permit: new cabinet boxes, new counters, a new backsplash, new flooring, and a dishwasher, range or hood dropped into the same spot with the existing connections. The permit is triggered by a moved sink or gas line, a new island with plumbing or power, a new circuit for a larger range or a second oven, a wall removed or opened, or a window enlarged for the view.

The gray zone is the appliance upgrade. Replacing a range with the same type on the existing circuit is a plug-in. Going from a 30 inch electric range to a 48 inch dual fuel unit usually means a new dedicated circuit and often a gas line change, and both of those are permitted work. Same with the island: an island with a prep sink or an outlet is a plumbing or electrical permit even if no wall moves.

Whether the change is worth a permit is a design question we answer at the walkthrough. If you are weighing layout changes, the kitchen page covers how we sequence cabinets, counters and the trades under one schedule.

Where the line sits in a bathroom

In a bathroom, replacing the toilet, faucet, showerhead, light fixture, exhaust fan or vanity in the same location is exempt, and so is tile, paint and flooring. Moving a drain, adding a fixture, converting a tub to a walk-in shower with new rough plumbing, adding a circuit for a heated floor or a second vanity, or removing a wall to enlarge the room all require a permit.

The tub-to-shower conversion is the one homeowners underestimate. Pulling a tub and setting a shower pan in the same footprint sounds like a swap, but the drain moves from the tub location to the center of the pan, the valve is usually replaced, and the waterproofing has to be inspected before tile covers it. That is exactly the inspection you want: a shower pan that fails after tile is the most expensive bathroom repair there is. Our bathroom remodeling page explains how we treat the waterproofing step.

Adding a bathroom, or adding a fixture to an existing one, is always permitted work and also changes the plumbing fixture count the city tracks for sewer capacity. Plan on plan review, not the no-plan permit, for anything that adds fixtures.

The No-Plan Building Permit

Information Bulletin 203 lets the city issue a building permit without plan review for a remodel of an existing kitchen or bathroom in a house, duplex or townhouse when there are no changes to structural elements, wall framing or exterior walls and no added plumbing fixtures. The same permit covers same-size door and window replacements, re-stucco and siding, drywall repair, replacement in kind, and prefabricated fireplace replacement. It is applied for through the online portal and requires a pre-construction inspection.

This is the permit most kitchen and bath remodels in San Diego should be on. It exists precisely for the project that rewires the outlets, replaces the plumbing behind a new vanity, and moves nothing structural. What disqualifies you: any structural modification, any change to an exterior wall, any added fixture, pre-engineered structural elements that need calculations, roof replacement, and homes in historic districts, which get reviewed.

The no-plan permit is cheaper because plan check is the expensive half of the fee. Which brings us to fees.

What a remodel permit costs in 2026

The City of San Diego prices building permits by square footage, not by the value of the project, under Information Bulletin 501 (revised August 2026). A single dwelling unit remodel or addition that needs plan review starts at a base of $3,512.92 for plan check plus $2,228.29 for inspection, with per square foot increments on top. A No-Plan Building Permit has no plan check component. Mechanical, electrical and plumbing permits, such as a water heater or a panel, are priced under Information Bulletin 103.

Two things follow from the square footage basis. First, a modest kitchen and a high-end kitchen of the same size pay the same permit fee, so the fee is a smaller share of a bigger project. Second, the cheapest permit is the one that avoids plan review, which is a reason to design a remodel that keeps the structure and the fixture count when the layout already works. On the bid, the permit fee is its own line; you should be able to see it, and on ours you can.

Fees reset with the fiscal year, so treat any number in a blog post, including this one, as a pointer to the bulletin rather than a quote.

Windows, doors, water heaters and panels

Replacement windows and exterior doors in a detached single family home, duplex or townhouse are exempt when they fit the existing rough opening, do not require changes to the weather resistive wall envelope, and were not required to be fire resistive. Water heater replacement, HVAC installation, new circuits and in-wall plumbing replacement require a permit; replacing switches, receptacles, light fixtures, appliances and surface plumbing fixtures does not.

The window exemption is generous by California standards, and it is easy to step outside it. Turning a slider into a French door, raising a header, or moving a window to a new wall all change the opening, and all need a permit. Multi-family buildings and commercial properties need a permit for any window replacement. Historic districts and environmentally sensitive lands are excluded from the exemption entirely.

Water heaters and panels are Simple MEP Permits. The city’s FAQ says homeowners generally receive one within two business days of submitting the owner-builder form, and a licensed contractor pulls it as part of the job. A tankless conversion adds gas line sizing and venting to the same permit.

Permit expiration and the 180 day rule

City of San Diego building permits expire 3 years after issuance for single family homes and duplexes and 4 years for other structures. After work begins, a valid inspection must be passed at least every 180 days, or the permit lapses and has to be renewed before the next inspection.

The 180 day clock is what bites paused projects. A remodel that stalls waiting on cabinets or a homeowner decision can quietly cross six months without an inspection, and the fix is a renewal fee and sometimes a re-review. We schedule inspections against the construction calendar so the clock is never a surprise, and if a project needs to pause we book an inspection on the work already done before it stops.

Owner-builder permits and who has to pull them

A homeowner can pull their own permit in San Diego by filing the Owner-Builder Verification Form, DS-3042. Under state law, a contractor hired for work that requires a permit, or for any job over $1,000 in combined labor and materials, must hold a California contractor’s license, and the licensed contractor is responsible for obtaining the permits for their work.

Owner-builder is a real option for a homeowner doing their own finish work, and a risky one when it is used to let an unlicensed crew work under the homeowner’s name. The permit holder carries the liability. If a contractor asks you to pull the permit for work they are doing, that is the moment to check the license number on the CSLB site. Ours is on every page of this site: California General B #1151759. What that license covers is on the general contracting page.

Unpermitted work: what it actually costs you

When the city finds unpermitted construction, code enforcement can stop the work and require a retroactive permit, which means opening finished surfaces for the inspections that were skipped and correcting anything that fails. When you sell, California’s Transfer Disclosure Statement requires you to disclose unpermitted work you know about, and buyers, appraisers, lenders and insurers all react to that line.

The practical damage is rarely a fine. It is the tile that comes off a shower wall so the inspector can see the pan, the drywall opened to check a junction box, the escrow that stalls while a retroactive permit works through the system, and the insurance claim that gets questioned because the water heater that failed was never permitted. Most of it is avoidable for the price of the permit and a few inspections during the job.

If you have inherited unpermitted work, it can usually be legalized. Interior remodels go through the standard retroactive permit route; unpermitted ADUs have their own path under the city’s Information Bulletin 242 and, for units built before 2020, state law AB 2533. Bringing older work up to code is a common part of a whole-home remodel, and we price it as its own line so you know what is legalization and what is new work.

The unincorporated county

Homes in Lakeside, Ramona, Spring Valley, Alpine, Fallbrook, Valley Center and the other unincorporated communities permit through County of San Diego Planning & Development Services, not the city. The county’s exemption list, form BD 110, mirrors the shape of the city’s: painting and finish work, accessory buildings of 120 square feet or less, fences up to 6 feet, retaining walls up to 3 feet from the footing, and patio covers up to 300 square feet, with a separate list of exempt minor electrical work.

The county’s list is a little tighter on fences (6 feet rather than 7) and it does not publish a no-plan remodel permit in the city’s form, so a kitchen or bath that touches plumbing or wiring goes in as a county building permit with the appropriate plans. Every other city in the county, from Carlsbad to Chula Vista to El Cajon, has its own building division and its own version of this list; the state building code is the same everywhere, the exemption thresholds and the fee schedule are local.

How we handle permits on a NewGen job

The permit question gets answered at the walkthrough, not after the bid. We sort your scope into exempt work and permitted work, decide whether the project fits the no-plan permit or needs drawings, and put the permit fee in the written bid as its own line. When plan review is required, the architect on our team prepares the set and submits it. During construction we book inspections against the schedule, and the permit is finaled before we call the job done.

If you are in La Jolla, Point Loma or another Coastal Overlay Zone neighborhood, we also confirm the overlay before the first drawing. See what we build on the work page or request the walkthrough.
