The San Diego Remodeling Permit Guide for 2026: Which Permit, What It Costs, How Long It Takes

"Do we need a permit for this?" is the second question in most first meetings, right after the budget, and the honest answer in San Diego has three parts: which permit path your project takes, which office issues it, and what that office charges and takes in 2026. None of the three is hard to know. All three are hard to find in one place, because the City of San Diego, the County and the seventeen other cities each publish their own bulletins, fee schedules and review times, and the state changes the codes underneath them every three years. This guide puts the 2026 answer in one place, with the City's own fee schedule and review dashboard, the County's, what the other cities publish, what our own records say about where San Diego remodels sit and which path they take, and what the 2025 codes changed on January 1.

Every figure is from a named public source, read in November 2026, or from Kaminskiy's own records, published as shares rather than counts. Where a number could not be verified on an official page, we say so rather than guess.

Which permit your project takes

In the City of San Diego, a remodel takes one of three paths, and the path is decided by one question: does anything structural move, and is anything added? A kitchen that keeps its layout and a bathroom that keeps its fixtures take the simplest path. A wall coming down, a window enlarged, a sink added, any new square footage or any new unit goes through plan check. A handful of small jobs need no permit at all.

The City's Rapid Review track, which replaced the old over-the-counter counter, is the one most remodels should be aiming for. Its eligible scopes include first-floor additions up to 750 square feet on a single-family home or duplex, interior remodels and garage conversions, City-standard patio covers, carports and retaining walls, and master-plan pools up to six feet deep. There is no added cost, and in the autumn of 2026 its combined review averaged seven days for a first review and three for a recheck. Whether a project qualifies is decided at submittal by its scope, which is why the way the drawings are scoped is worth as much as the drawings.

Where the house sits decides which office you deal with

San Diego County has nineteen building departments: the City of San Diego's Development Services Department, the building divisions of the seventeen other cities, and the County's Planning & Development Services for every unincorporated community, from Rancho Santa Fe and Ramona to Lakeside, Spring Valley and Bonita. They enforce the same state codes and they price and schedule the work differently. Here is where the homes we are asked to price actually sit.

Three things change with the office. The fee basis: the City of San Diego and the County price a permit by the square footage and type of the work; most of the other cities price it by the construction valuation, the same project costing more or less depending on how the city's table reads. The review clock: the City publishes a live dashboard, the County publishes a typical backlog, and several cities publish a target in business days; the rest publish nothing. And the reviews that attach: historic review and the Coastal Overlay Zone are City rules; fire protection plans, septic layouts and grading reports attach in the County and the fire zones.

What our own records say: most San Diego remodels go through plan check

Because the permit path is decided by scope, we can say from our own records which path the projects San Diego families ask us about would take. Among the remodel inquiries Kaminskiy has typed since 2021, nearly two in three are projects that always go through plan check: an addition, an ADU, a whole home, outdoor structures. The rest are kitchens and baths, which can take the no-plan permit when the layout stays and go to plan check when it does not.

The second thing our records say is about timing. At the first call we ask when a family wants to start, and more than half say right away. A same-layout kitchen or bath can honor that, because its permit can issue in days and the schedule is set by cabinets and tile rather than by the City. An addition, an ADU or a whole home cannot, because weeks of design and engineering come before a submittal, and the review comes after. That gap, between when people want to start and when a plan-checked project can, is the one a permit guide is for.

The permit is the first thing I want settled, not the last. On the day a design agreement is signed I want to know three things: which office, which path, and whether the house is 45 years old, because that review runs before anything else and we start it the day we have an address. Once I know the path I can tell a family which month they will be in construction, and I can tell them honestly. The projects that go wrong on the calendar are the ones where someone assumed the permit was a formality and found out in week eight that it was plan check.

What the City of San Diego charges in 2026

The City prices construction permits by the type and square footage of the work under Information Bulletin 501, with the electrical, plumbing and mechanical permits priced separately under Information Bulletin 103. Every fee rose 7.25% on May 4, 2026, the second increase in twelve months after 12.3% in May 2025, and since July 2025 the City bills at the rate in force when it invoices rather than when the application was filed. These are the lines a remodel meets, as the August 2026 schedule reads.

Put together, a same-layout kitchen or bath in the City is a $441 permit plus the mapping fee. A kitchen that takes a wall out, or an addition of up to 500 square feet, is $5,741 in plan check and inspection plus the $737 general plan fee and the trade permits, around $7,000 by the time the circuits and the gas line are in. An 800-square-foot addition is about $9,900 to the City and $4,304 to the school district. A detached ADU of 500 square feet is priced like a small addition; one of 750 square feet lands in the schedule's larger tier at about $16,500 before the general plan fee, with a school fee on the space above 500 square feet. The school fee is where a round number matters: California lets a district charge it only when a project adds more than 500 square feet of assessable space, San Diego Unified's rate is $5.38 per square foot since May 2026, and the same $5.38 applies in Poway Unified. An addition of exactly 500 square feet pays nothing; one of 501 pays on all 501.

Impact fees are a separate matter and mostly a non-issue for a remodel: the City waives development impact fees on an ADU of 750 square feet or less, and state law says an ADU is not a new use for water and sewer capacity charges unless it is built with a new house. The 2026 City permit fees are in our cost articles for a kitchen, a bathroom, an addition and an ADU, where they sit beside the rest of the budget, and in every one of them the permit is the smallest line by far.

The County and the other cities

If the house is in an unincorporated community, the permit comes from the County of San Diego's Planning & Development Services under fee schedule PDS 613, revised July 2026. The County's lines are simpler than the City's and, for a plan-checked remodel, usually cheaper.

The County publishes what the City's dashboard shows: the typical backlog before a first residential plan check is about four weeks, about half of projects need more than two cycles, and a plan check stays valid for a year. Some minor projects with clean drawings can be processed over the counter at the counter staff's discretion, usually with one return visit. The County's own triggers are the ones a city homeowner never meets: in a high or very high fire hazard zone the fire authority can require a fire protection plan and does require a landscape plan for any addition, with fuel modification 100 feet out from the building; a house on a septic system needs the Department of Environmental Health to approve a layout before a bedroom or a bathroom is added, and in almost every case an ADU exceeds the existing tank; and a grading permit attaches when a cut or fill exceeds eight feet or 200 cubic yards, though excavation for a pool or a retaining wall under a valid building permit is exempt.

The seventeen other cities each run their own building division. Most price permits by construction valuation rather than square footage, and the ones that publish a review target are worth knowing, because a first review of two to three weeks becomes six to nine weeks across three cycles.

How long it takes in the City in 2026, from the City's own dashboard

The City publishes a permit timeline page that is updated weekly: how many projects sit in each queue and the average days to complete a first review and a recheck over the previous 30 days, by discipline and by track. Read on November 6, 2026, with data as of October 30, it says what a remodel should expect this season.

Three points of reading. The clock starts when the project is deemed complete and the set-up fees are paid, not when the drawings are uploaded; a submittal with a missing document sits in intake, which averaged two days in the queue. A project is reviewed by every discipline it touches at once, so its first cycle takes as long as its slowest reviewer: a kitchen with structure is a combined review, about two weeks on the standard track, while a project that needs a storm water or electrical review waits a month. And two cycles is the honest planning number: a first review, corrections, a recheck, then one business day to issue. On the standard track that is five to six weeks; on Rapid Review it is under two; with Express it is about three. The County's four-week backlog before a first review, with half of projects needing more than two cycles, puts a plan-checked County project at two to three months.

Two state clocks sit on top of the City's. An ADU application must be approved or denied within 60 days of being complete or it is deemed approved, and from this year the City has 15 business days to tell an applicant what is missing. And since October 2025, any project that adds a dwelling unit of any kind, an ADU included, has a 30-business-day limit on each building-permit review under the state's post-entitlement law; if the City misses it, the applicant can hire a licensed third-party plan checker and the City reviews that report within ten business days. A remodel that adds no unit has neither clock, which is one more reason the ADU reviews in the chart run shorter than they used to.

What changed on January 1, 2026: the 2025 codes

Every permit application filed since January 1, 2026 is reviewed under the 2025 California Building Standards Code, and the City's local amendments to it took effect on April 22. A state law passed in 2025 now freezes local amendments to the residential codes until June 2031, except for emergencies, wildfire and specified emissions rules, so the set below is the set San Diego will build to for the next five years. These are the items that reach a remodel.

Inspections, expiration and the paper that follows the permit

A permit is a schedule of inspections. In the City they are requested at least one day ahead, through the portal or the automated line, and performed on weekdays between 8:30 and 3:30; the City warns that a high volume of requests can push an inspection to the next day. The sequence on a typical remodel is foundation and underground, rough framing, rough electrical, plumbing and mechanical, insulation and drywall, then the finals for each trade and the building. Nothing is covered until the inspection before it has passed, which is why a remodel's calendar is a chain of inspections with the trades sequenced between them.

The clocks on the permit itself are worth knowing before you sign anything. In the City, a building permit application that has not been issued two years after it was deemed complete is closed, with one 180-day extension for circumstances beyond the applicant's control. An issued permit is void if substantial work has not been completed and validated by an inspection within 12 months, or if the work is suspended for 180 days; a permit on a house, a duplex or a townhouse expires three years after issuance, with one 180-day extension requested at least a month before the end. A stand-alone trade permit expires after 180 days without an inspection and cannot be extended. In the County, work must start within two years, pass an inspection at least every 180 days, and finish within three; a lapsed permit is renewed at half the current fee, or a quarter if only the final is left. A phased project lives inside those windows by design.

Unpermitted work, owner-builders and who pulls the permit

The Contractors State License Board puts the rule plainly: no building may be constructed, enlarged, altered or repaired unless a permit has first been obtained from the building official, and the requirements vary by city and county. On a contracted job the contractor pulls the permit under their license; the City's permit records are public, so a homeowner can confirm one exists before the first check clears. California also caps a contractor's down payment at $1,000 or 10% of the contract price, whichever is less, and a contractor may not collect for work not yet done. A homeowner who pulls the permit as an owner-builder is taking on the contractor's role under Business and Professions Code 7044: the exemption holds only when the owner does the work or hires licensed contractors directly, and a sale within a year of completion is presumed to have been the point.

Work done without a permit does not go away. The state's Transfer Disclosure Statement, which every seller of a house signs, asks whether any additions, structural changes or other work were done without the necessary permits, and an undisclosed answer is the buyer's claim later. A lender's appraiser and a buyer's inspector both look for square footage the assessor does not show. Legalizing after the fact means opening finished walls for the inspections that were skipped, bringing the work to the current code rather than the code of the year it was built, and paying the fees with an investigation surcharge on top. The one amnesty on the books is for ADUs: under Information Bulletin 242, the City cannot deny a permit for an unpermitted ADU built before January 1, 2020 unless it is substandard, and no water or sewer capacity fees apply, though the standard permit and school fees do.

How we run the permit on a Kaminskiy project

Design-build means the permit is ours to run, not yours to chase, and it runs in parallel with the work that takes longer. The sequence on our projects: the path and the office are named at the first meeting; the historic review is filed the day the design agreement names the address; drawings are scoped to qualify for Rapid Review when the project allows it, and submitted on Express when a family's calendar is worth the premium; the Title 24 energy forms, the structural calculations and the trade permits go in with the building permit so no discipline waits on another; corrections are answered in days, not weeks, because the designer and the engineer who drew the set are the ones answering; and selections and long-lead orders run through the review, so that the week the permit issues is the week the cabinets are on a truck. Our timeline guide shows where the permit sits on each project's calendar, and our process page shows who does what at each step.

Before you start

1. Find out the year the house was built and the zone it sits in. Built before 1981 means a historic review before anything else; the Coastal Overlay Zone, a very high fire hazard zone and an HOA each add a review of their own.
2. Decide the layout question before the finishes. Keeping the walls and the fixtures where they are is the difference between a permit that issues in days and one that takes six weeks, and between $441 and $7,000 in fees.
3. Keep an addition at 500 square feet or less if 500 does the job. The school fee starts at 501 and is charged on every square foot.
4. Ask which track the drawings will be submitted on. Rapid Review costs nothing extra and runs in a week; a set scoped to qualify for it is worth more than a set that is merely complete.
5. Budget the fixtures the permit will touch. On a pre-1994 house, every old toilet, showerhead and faucet is replaced before the final, and every altered light is high efficacy.
6. Confirm the permit exists before the work starts. The City's records are public; a contractor who will not show you the permit is telling you something.

How we built this guide

The first-party figures come from Kaminskiy's own customer records, 2021 to 2026, analyzed in November 2026: every inquiry with a project address in San Diego County, mapped to the building department that would issue its permit; every remodel inquiry carrying a project type, mapped to the City of San Diego permit path that type takes (handyman and commercial work excluded); and the start date homeowners gave at the first call, grouped into right away, within about three months, and later or flexible. Our records cannot see whether a kitchen kept its layout, so the no-plan share is the share eligible by type. We publish shares, never counts, and no client's information leaves the analysis. The City and County figures are the published schedules and the City's dashboard as read on November 6, 2026; the City updates its fee schedule each spring and its timeline page weekly, so these numbers will move, and this guide is refreshed quarterly. Three items we could not verify on an official page are left out rather than guessed: the City's current water and sewer capacity charge amounts, a published processing time for a Coastal Development Permit, and whether the City or County requires a seismic gas shut-off valve on a remodel permit.
