How Much Does a Building Permit Cost? 2026 City Fees

How Much Does a Permit Cost? Real Numbers from 14 Major US Cities (2026)

This isn't just permits. It's every cost from Uncle Sam down to your friendly local government, and it adds up: government regulation accounts for 24.3% of the final price of a new single-family home. That's not my number. That's NAHB's most comprehensive study, and what it means is that nearly a quarter of the price of a new home goes to fees, compliance, and permits before a single nail gets driven or real estate agent gets a phonecall.

A quick word on the numbers you'll see throughout this piece. The 24.3% figure is the full regulatory share baked into the price of a finished home, the headline stat. Of that load, permit, hook-up, impact, and other fees specifically averaged 5.3% of construction costs in NAHB's study. The permit fee on its own is a smaller slice still. Keep that hierarchy in mind and the rest of the article hangs together.

What you're actually paying for when you pull a permit

When you pull a permit, you're not just buying a piece of paper from the city. You're paying for the infrastructure that reviews your plans, inspects your work, and certifies the structure meets code. That 5.3% average covered permit, hook-up, impact, and other fees in NAHB's 2016 special study. The upper quartile hit 7.0%.

That study, authored by Paul Emrath, Ph.D., tracked regulations at every level of government. The permit fee itself is just one line item in a stack. You're also funding plan reviewers, inspectors, administrative staff, and the building department's overhead. That much red tape doesn't roll out for free.

The U.S. Census Bureau tracks building permits monthly. March 2026 came in at a seasonally adjusted annual rate of 1,372,000 privately-owned housing units authorized. That's a lot of permit fees flowing into municipal coffers nationwide. The Census collects this data through their Building Permits Survey at the U.S., region, state, metro area, county, and place levels. 2025 annual data drops May 14, 2026.

Here's the part that bothers me. NAHB's 2025 analysis showed building permit fees alone doubled from 0.9% to 1.8% of total construction costs since 1998. That's permit fees specifically, the narrowest slice of the stack, not the broader 5.3% fee average and certainly not the full 24.3% regulatory load.

Most cities enforce permits for any project exceeding $500 in valuation. There's a few exempt jobs but not many. Any structural change will basically need a permit (or several). Denver goes further. Their policy ADMIN 138 sets the floor at $1.

That regulatory load isn't trending down. Regulatory costs grew 29.8% between 2011 and 2016. Disposable income grew 14.4% over the same stretch. That gap is widening, not closing. I don't know about you but that doesn't sit too well with me.

Why the same bathroom permit costs $200 in Boston and $411 in San Diego

A building permit for a standard bathroom remodel in Chicago costs $602. That's the minimum. The city charges at least that much regardless of project size. The formula underneath multiplies square footage by a construction factor and a scope factor from the 2026 fee tables. But for a typical residential bathroom, the $602 floor kicks in every time. This is a strange "bonus" with Chicago. Although they do have a moderately complex fee structure for most projects the math is simple on the paying for it side of things. "That'll be 602 please."

Chicago's formula, spelled out in Municipal Code 13-32-310, uses a scope factor around 0.25 for repairs and 0.75 for additions. A small repair and a small addition with the same footprint can both land at the same $602 minimum. Different work, same price.

Boston's Inspectional Services Department charges a Long Form building permit at $50 primary fee plus $10 per $1,000 of estimated cost. A $15,000 bathroom remodel comes out to $200 for the building portion alone. This means that if you were doing a $1,000 bathroom remodel (don't we all wish that was a thing) you could end up paying just $60 for that permit.

Now then, let's compare that Boston permit to San Diego. For a standard bathroom or kitchen remodel, San Diego issues a combined trade permit at about $411 under Information Bulletin 203, not a per-square-foot charge. The city does run a square-footage construction schedule, but it applies to new builds and structural work, not a routine remodel. So that same small bathroom lands near $411 in permit fees, well above Boston but nowhere near the four-figure number a misread schedule might suggest.

San Diego isn't cheap, but for remodels it isn't the outlier some people claim either. The genuinely punishing permit markets are cities like Seattle, where an $8,000 project already runs over $900 and a mid-size job clears $1,400. Those are the fee tables I'd weigh before starting a contracting business somewhere, not a San Diego combined remodel permit.

Denver's Community Planning and Development charges $20 for projects under $500, and the fee ramps up to $220 base plus $8 per $1,000 above $25,000. Their ICC valuation table lists residential interior renovations at $60 per square foot, with finished basements at $35 per square foot.

Phoenix bases fees on square footage multiplied by a standard rate per occupancy. One building permit covers all trades. You don't pay separate plumbing, electrical, or HVAC fees. That's the opposite of Boston and Austin, where each trade stacks separate base fees. Austin's FY 2025-26 schedule charges by square footage, splits across building, electrical, plumbing, and mechanical, and adds a flat $66 energy code review fee. A basic and a high-end bathroom with the same footprint pay identical permit costs there.

Permit cost by project type

Bathroom and kitchen remodels hit differently than roof replacements or new construction. Each project type has its own minimum, its own fee structure, and its own trade permit stacking.

In Boston, plumbing permits run $20 primary fee plus $5.00 per fixture. Electrical permits are $20 plus $10 per $1,000 of estimated cost. These stack on top of the building permit for any kitchen or bathroom job. You're paying three times for one project.

Denver handles residential shingle roof replacements through their Quick Permit program. No plan review required when repairs exceed 10% of the roof area or two roof squares, whichever is smaller. The valuation table sets those projects at $5.25 per square foot. Quick Permits aren't available for commercial buildings 25,000 square feet or larger, green roofs, or structural framing changes.

Solar gets a break in Denver. A flat $50 permit fee reduction for photovoltaic and other renewable energy projects. Zero dollar plan review fees. One of the only project types where the city undercharges.

New construction in San Diego is genuinely expensive, because a ground-up permit uses the square-footage construction schedule rather than the flat combined remodel permit. The exact figure scales with size and scope, so pull the city's current IB-501 schedule rather than trust any rule of thumb. For a remodeler the takeaway is simpler: your bathroom or kitchen permit is the roughly $411 combined fee, not a new-construction number.

Seattle's 2026 numbers jumped hard. A 1,500-square-foot single-family house with garage permits at $6,853 in plan review and permit fees. That's a 19% increase from 2025's $5,759. A 500-square-foot DADU runs $3,453, up 18.7% from $2,908 the year before. Even the smallest residential project costs over $3,000 in city fees.

Phoenix pool permits start at $180 minimum plus a $30 aquatics program surcharge. That's $210 before plan review kicks in. Their Building Valuation Table was revised January 20, 2026.

Atlanta sets project-type minimums that override the standard floor. Single-family decks, balconies, and porches minimum at $350. Re-roofing at $360. Residential demolition at $650. Los Angeles ranges from $200 for minor work like water heaters to over $15,000 for major construction, calculated automatically by their permit fee system based on project valuation.

Boston also requires a separate Trench permit at $60 primary fee with three signatures needed. Valid for six months. Site work for additions or pool projects often gets missed when scoping the full permit cost.

City-by-city snapshot: 14 major US markets

A few of these last figures (Miami's per-trade minimum, Portland's state surcharge, San Francisco's percentage range) come from general industry reporting and contractor experience rather than a single linked fee schedule. Treat them as ballpark. The cities with direct links above (Chicago, Denver, Seattle, NYC, Atlanta) are the ones you can verify line by line. Always confirm with the building department before you budget.

Plan for Plan Review (or Plan for a Headache)

Plan review fees catch people off guard more than anything else. Denver charges 50% of the building permit fee as a separate plan review fee for projects over $2,000, and the review won't begin until that fee clears. Most jurisdictions land between 50% and 65% of the permit fee. San Diego County and Federal Heights, Colorado both set it at exactly 65%. Houston takes 25% of the estimated building permit fee upfront, so a $400 permit triggers $100 before the city looks at your drawings.

Seattle splits the bill differently: 75% of the total permit fee when you submit the plans, the remaining 25% at pickup. You commit most of the money before knowing if your plans pass, and pushing back on that structure doesn't work. It's policy.

Reinspection fees also add up fast. Denver charges $100 per hour for reinspections or any inspection outside normal business hours, with a two hour minimum for off-hours work. Fail one inspection and you're paying at least $200 to bring someone back. Their policy notes permit fees cover customary inspections only.

Denver also charges $125 per hour with a two hour minimum for additional plan review on incomplete or modified drawings. That kicks in automatically on the third review cycle if your plans didn't address any prior comments.

Boston's ISD charges $100 per event for off-hour applications and $250 for off-hour inspections, both standard and on top of base permit fees.

Chicago's $600 non-refundable application deposit carries a matching $600 penalty if the application is incomplete. That's real money at risk.

Denver's Phased Construction Permit policy adds 25% for two-phase permits, 50% for three or more. Projects that elect to permit foundations separately from the superstructure get surcharged.

California's 2025 Title 24 energy standards hit permits filed January 1, 2026 and later. Many cities pass the review cost through as a separate surcharge. Denver's contractor license runs $250 every three years. You're paying that whether you see it itemized or not.

When to fight the cost vs just pay it

Don't start work without a permit. Full stop. Boston's ISD doubles the permit fee when they catch work started without authorization, and Phoenix does the same. Many Florida cities explicitly list a 2x penalty. Repeat violations can triple or quadruple the cost. You're not saving money by skipping the permit. You're borrowing trouble at a steep interest rate.

Denver offers Express plan review at 20% of the permit fee, with a minimum charge of $100 and same-day turnaround. It costs less than full plan review for projects over $2,000 plus all demolition jobs. That's worth paying if you can move faster.

Know when the cost just reflects reality. San Diego charges by square footage, not valuation. Austin does too. A basic bathroom and a luxury bathroom of the same footprint get identical permit fees in those cities. There's no fighting that formula. It's how they built their schedule.

Homeowners can only pull permits themselves for single-family homes in Denver, not ADUs. Every other project requires a licensed contractor, and the contractor's license fee gets folded into your invoice. You're not negotiating that away.

You don't actually get to negotiate much, but here's a solid tip. Declared valuations matter if a city uses valuation-based fees, so don't inflate your project cost. Declare what the work actually costs. Denver uses ICC tables to set minimum valuations if your number looks low, so don't pretend your whole remodel is 93 dollars either. Be accurate, maybe even conservatively accurate. That's about the only "cost saving" method that exists, and only in places that use fees based on value of course.

Get your exact number before you budget

The fee schedules above give you ranges. They give you formulas. They don't give you your exact number on your specific project at your specific address.

Chicago's Department of Buildings runs a permit fee calculator on their website. Punch in your project details and it computes the fee using the square footage, construction factor, and scope factor formula from Municipal Code 13-32-310. Minimum $602. That number will hold for virtually every project.

Boston's Inspectional Services Department publishes their full fee schedule online. The Long Form building permit at $50 plus $10 per $1,000 of estimated cost is straightforward math, but the trade permits stack. Plumbing, electrical, each with their own formula. You need all three numbers to get your real total.

San Diego's Information Bulletin 501 lays out the full FY 2026 construction permit fee schedule. The square-footage formulas for residential remodels are all there. Base fees, per-square-foot rates, plan check side, inspection side. Run your project square footage through their numbers and you'll get close.

Don't guess. Don't use 2022 numbers. Fee schedules change. Seattle raised fees 6.5% to 18% on January 1, 2026. San Diego's schedule is fiscal year 2026 specific. Pull your city's published schedule or call the building department, or both. It's best to budget the correct amount. Oh, and do budget something. The only thing worse than not planning your costs correctly is not securing your permits at all. Under budgeting is an oversight. Getting hit with double or triple penalty fees plus project delays is a nightmare.
