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.

Kansas City charges $84 for an $8,000 project. That single fee covers the building permit plus mechanical, plumbing and electrical work. I dug through Section 18-20(b)(2) of the city code myself to confirm the details. The numbers are straightforward. But the structure differs from cities that nickel and dime you with separate trade permits.
How Kansas City Calculates Permit Fees
Kansas City uses a valuation based formula for one and two family homes. Projects from $2,001 to $100,000 start with a $58 base then add $4.33 per thousand. An $8,000 job comes out to $84. A $15,000 bathroom hits $114. I ran the exact math from the code several times.
Plan review costs 50 percent of the permit fee. They credit it back toward the total though. That keeps the final number reasonable. The minimum fee sits at $52. (Not cheap for a tiny job but it beats the old days.)
This single permit bundles everything. No separate charges for electrical or plumbing on houses. Section 18-20 spells it out clearly. I had to cross reference the building code chapter with the fee table to see how they folded it all together. Other cities make you file four permits and pay four times.
The tier drops to $1.41 per thousand once you clear $100,000. Bigger jobs don't punish you as hard. But don't expect the schedule to stay this gentle forever. Cities adjust these numbers. If your contractor's bid doesn't list the permit cost separately add it yourself.
Chuck’s Take
“I always add the permit cost into my bids now. Kansas City may seem reasonable at $84 but homeowners still forget. Don't get caught short when the invoice comes.”
Leonard “Chuck” Thompson, LC Thompson Construction Co.
What Needs a Permit in Kansas City?
Most structural changes need a Kansas City building permit. New decks, roof replacements and basement finishes all require approval. The city lists exempt work in Section 18-16 of Chapter 18. Simple painting and flooring usually don't trigger it.
You'll need one for a water heater replacement. Same for window swaps that change size. I checked the official site and the code. They don't let you skip inspections on plumbing or electrical work.
Do I need a permit in Kansas City to build a shed. Probably. Same for fences over six feet and most carports. The rules protect your neighbors and your future sale. Skipping them creates headaches later, and Nobody wants that.
Penalties for Skipping Permits in Kansas City
The penalty for unpermitted work in Kansas City is triple the normal fee. Section 18-20 makes that clear. You pay three times what the permit would have cost. That adds up fast on a $15,000 bathroom.
Code enforcement doesn't play around. They can issue stop work orders too. I didn't find daily fines listed but the triple fee alone hurts. Homeowners get caught during property sales, and title companies spot the missing permits. Don't risk it.
How Long Is a Building Permit Good For in Kansas City?
Permits last 180 days before you must start work. The city also gives you 180 days before abandonment kicks in. You can request extensions. The building official reviews written justification for 90 day renewals.
File early. Don't let the clock run out on a half finished deck. I saw this rule in Section 18-19. Simple but important.
Who Pulls the Permit in Kansas City?
Homeowners can only pull permits for their own owner occupied single family home. You must do the work yourself. Everyone else needs a licensed contractor. That includes two family buildings and any rental property.
The rules appear on the city's electrical plumbing and mechanical permits page. Contractors handle the paperwork for good reason. They carry insurance and know the inspections. If someone asks you to pull the permit yourself walk away.
Chuck’s Take
“If a contractor wants you to pull your own permit that's a red flag. Kansas City rules are strict on this. Hire someone who takes responsibility for the work.”
Leonard “Chuck” Thompson, LC Thompson Construction Co.
Kansas City's Single Permit System
Kansas City bundles all trades into one permit for houses. One application, and One fee. One set of inspections, and Section 18-20(b)(2) created this approach. Most cities don't operate this way.
The formula stays simple at typical remodel values. You avoid paying separate base fees for plumbing and electrical. I compared it against 26 other fee schedules. This structure saves time and reduces mistakes. (The city doesn't bury the details on page nine of some forgotten PDF either.)
The all in fee makes budgeting easier. You won't get surprised by extra trade charges. If your project value is clear from the start the math works in your favor.
