Two Types of Permits
Kansas City 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.

Kansas City prices permits for one- and two-family homes from one valuation table in Section 18-20(b)(2): $58 for the first $2,000, plus $4.33 for each additional $1,000 or fraction. An $8,000 job pays $83.98 and a $12,000 job $101.30. Reroofing, siding and same-opening window replacement need no permit at all. A remodel takes a building permit plus separate plumbing and electrical permits, each on its share of the value: $256.27 for a $25,000 kitchen and $217.30 for a $15,000 bathroom.
Kansas City Permit Fees Explained
Section 18-20(b)(2) prices "One- and two-family detached dwelling building, mechanical, plumbing, electrical, elevator and fire protection permit fees" from one table: $52 up to $1,000, $58 up to $2,000, then $4.33 for each additional $1,000 or fraction to $100,000, and $1.41 per $1,000 above that.
Worked through: an $8,000 job is $83.98, a $7,100 deck $83.98, a $12,000 job $101.30, a $3,000 panel upgrade $62.33, a $15,000 solar installation $114.29, a water heater $58. Demolishing a house is a flat $90 permit plus a $38 pre-demolition inspection, $128.
The City files a kitchen or bath remodel as separate permits, a building permit plus plumbing and electrical permits, each priced from the table on its own share of the value. That puts a $25,000 kitchen at $256.27 and a $15,000 bathroom at $217.30.
Chuck's Take
"I bid a lot of jobs in Missouri. Kansas City permit fees are lower than people expect, and a lot of exterior work needs no permit at all. Put the permits you do need in the bid upfront. Clients forget it otherwise."
Leonard "Chuck" Thompson, LC Thompson Construction Co.
What Needs a Permit in Kansas City?
Section 18-16(b) lists work that needs no building permit. It includes fences (any fence), reroofing a one- or two-family house with a light roof covering (not sheathing or structural work), replacing exterior wall covering, replacing doors and windows in existing openings, one-story accessory buildings up to 200 square feet of roof area, retaining walls up to four feet, decks and platforms no more than 30 inches above grade, walks, patios and driveways on existing grade, cabinets, painting and floor coverings, gutters and tuckpointing.
Decks over 30 inches, remodels, water heaters, panel upgrades, solar and EV circuits need permits. Section 18-16 also lists separate mechanical, electrical and plumbing exemptions, such as replacing a defective fixture without altering the piping.
Penalties for Work Without a Permit in Kansas City
Chapter 18 is direct: "Where work for which any permit is required by this article is started prior to obtaining the permit, the fee specified for such permit shall be tripled." A $101.30 permit becomes $303.90. A conviction for a code violation can also carry a fine of up to $500.
Unpermitted work also surfaces at sale. Pull the permit before work starts.
How Long Is a Building Permit Good For in Kansas City?
An application expires 180 days after filing unless it is pursued in good faith or the permit is issued; the building official can grant extensions of up to 90 days each. Confirm the permit's own time limits with City Planning and Development when it is issued.
Who Pulls the Permit in Kansas City?
Homeowners can pull their own permit but only under strict rules. You must own the single-family house, live in it and do all the work yourself. The city website is very clear on this.
Licensed contractors must pull the permit for everything else. Two-family homes, investor-owned houses, any job where you're not swinging the hammer. This protects everybody.
Your contractor should pull the permit in their name. If they ask you to pull it that's a red flag. Insurance, liability and code responsibility all shift when the contractor pulls it.
Check the KCMO Electrical, Plumbing and Mechanical Permits page before you sign anything. The rules aren't complicated. But they matter.
Chuck's Take
"Never let a customer pull the permit if I'm doing the work. I want my name on it. That way the city calls me if something comes up. If a contractor asks you to pull it yourself walk away. It's not worth the risk."
Leonard "Chuck" Thompson, LC Thompson Construction Co.
One Valuation Table for Every Trade
Kansas City uses one valuation table for building, mechanical, plumbing, electrical and fire protection permits on one- and two-family homes, so any single permit is easy to price. A remodel that touches several trades is filed as separate permits, a building permit plus plumbing and electrical permits, each priced on its share of the job's value.
The exemption list is also unusually broad: reroofing, siding, same-opening windows and doors, and all fences need no building permit.
