"Do I need a permit for this?" is one of the most common questions homeowners ask us, and the honest answer in Kansas City is: it depends on what you're doing and which city you live in. The KC metro is a patchwork of dozens of jurisdictions across Missouri and Kansas, each with its own building department, portal, and fees.
The good news is that the logic is nearly the same everywhere, because almost every metro city bases its rules on the International Residential Code (IRC). This guide walks through what needs a permit, how to apply in Kansas City, Missouri and the major suburbs, what it costs, how inspections work, and why skipping permits is the most expensive shortcut in remodeling.
What Remodeling Work Needs a Permit (and What Doesn't)
Kansas City, Missouri publishes a specific list of work that is exempt from a building permit, and most suburbs follow similar logic drawn from the IRC. The pattern is simple: cosmetic, like-for-like finish work is exempt; anything structural or anything that touches electrical, plumbing, or mechanical systems needs a permit.
| Project | Permit Needed? | Notes |
|---|---|---|
| Painting, wallpaper, trim | No | Finish work is exempt in KCMO and most suburbs |
| Carpet & floor coverings | No | On KCMO's exempt list; structural subfloor repair is different |
| Cabinet swap, same layout | No | Replacing cabinets in the same location is exempt in KCMO |
| Low platform deck (<30" high) | Varies | Exempt in KCMO if under 30" and not over a basement; some cities permit all decks |
| Kitchen/bath remodel (moving fixtures or walls) | Yes | Building permit plus electrical/plumbing/HVAC trade permits |
| Basement finish | Yes | New walls, circuits, and egress requirements all trigger permits |
| Attached or elevated deck | Yes | Footing and framing inspections required |
| Room addition | Yes | Full plan review: foundation, framing, all trades, energy code |
| Removing or altering a wall | Yes | Even non-load-bearing wall changes are permitted work in most cities |
| Water heater / furnace / AC replacement | Yes | Trade permit (plumbing or mechanical) in most metro cities |
| Roof replacement, siding, windows | Varies | Many metro cities require a permit; check your city |
| Fence (under ~7 ft) | Varies | Often exempt from building permit but subject to zoning rules |
Two important caveats. First, "exempt from a building permit" does not mean exempt from code: the work still has to be done to code even when no permit is required. Second, this table reflects the common pattern across the metro, but thresholds genuinely vary by city. When in doubt, a five-minute call to your local building department settles it for free.
How to Apply in Kansas City, Missouri (CompassKC)
Kansas City, Missouri runs all permitting through the City Planning & Development Permits Division, and every application is submitted electronically through the CompassKC online portal. There is no paper option; even homeowners doing their own work create a CompassKC account and upload documents.
For a typical interior remodel or basement finish, KCMO asks for a written scope of work plus existing and proposed floor plan drawings. After review and approval, the building permit is issued through the portal. Electrical, plumbing, and HVAC work each require separate trade permit applications, normally pulled by the licensed contractor performing that trade. Kansas City adopted the 2018 family of International Codes (effective mid-2020), including the 2018 International Residential Code with local amendments, and later updated its energy code to the 2021 IECC, so plans are reviewed against those editions. Questions go to the Permits Division at (816) 513-1500 or cdpermits@kcmo.org.
Permit Portals for Major Kansas City Suburbs
Your permit comes from the city the property sits in, not from "Kansas City" generally. Here's where to start in the largest metro jurisdictions:

| Overland Park, KS | ePLACE online system via opkansas.gov Permits & Inspections |

What Building Permits Cost in the KC Metro
Almost every metro city calculates permit fees from the project valuation, the estimated cost of the work, so a $12,000 deck and a $60,000 basement finish pay different fees even in the same city. Kansas City, Missouri publishes its building and development fee schedule with a downloadable fee calculator, and one advantage of KCMO's system is that a single valuation-based fee bundles the building and trade permits for a residential project.
Realistic ballparks we see across the metro: $100-$300 for a typical deck or small remodel permit, $200-$500 for a basement finish or larger kitchen/bath remodel, and $500-$2,000+ for room additions, where plan review fees stack on top of higher valuations. A few cities also charge small flat fees, like Gladstone's $50 residential plan review. These are budgeting numbers, not quotes; the fee schedule for your specific city and project valuation governs.
The Inspection Process, Step by Step
A permit isn't just paperwork; it buys you a series of independent inspections at the moments that matter. On a typical permitted remodel, the sequence looks like this:
Application & Plan Review
A few days to a few weeksScope of work and drawings reviewed against the adopted code; the permit is issued
Footing / Foundation Inspection
Decks & additionsInspector verifies footing depth and size before any concrete is poured
Rough-In Inspections
Before drywallFraming, electrical, plumbing, and HVAC checked while everything is still visible
Insulation / Energy Inspection
Where requiredInsulation and air sealing verified against the energy code before cover
Final Inspection
Project completeFinished work verified; smoke/CO alarms, guards, and egress checked; permit closed out
Scheduling tip: Most metro cities let you request inspections online or by phone with about one business day of notice. The critical rule: never cover work (concrete, insulation, drywall) before its inspection passes, or you may be ordered to open it back up at your own expense.
How Long Permits Take in the KC Metro
For straightforward residential work (decks, basement finishes, interior remodels), most metro cities complete plan review in a few days to two weeks. Gladstone, for example, publishes a 3-5 day residential review target, and several Johnson County cities turn simple permits around in days. Room additions and structural projects take longer, typically two to six weeks, because they get full plan review and the city may ask for revisions. Spring and summer are the busy season; if your project is time-sensitive, apply early.
What Happens If You Skip the Permit
We get asked, quietly, whether the permit is really necessary. Here's what skipping it actually costs:
During the Project
- Stop-work orders – The city can halt the job the day it's discovered
- Doubled fees & penalties – Retroactive permits commonly cost two to three times the normal fee
- Open it back up – Inspectors can require finished walls and ceilings to be removed for inspection
- No safety backstop – Nobody independently checks the wiring, gas, or structure
Years Later
- Resale problems – Sellers must disclose known unpermitted work; buyers negotiate the price down or walk
- Appraisal gaps – Unpermitted square footage often can't be counted as finished living area
- Insurance risk – Claims tied to uninspected work can be reduced or denied
- Lending snags – Some lenders refuse mortgages until permit issues are resolved
These aren't scare stories. Legal publisher Nolo's guide to unpermitted construction walks through exactly how unpermitted work surfaces during a sale, and we've watched basement finishes that saved a few hundred dollars in permit fees cost sellers thousands at closing. The permit is cheap insurance.
Why Your Contractor Should Pull the Permit
On any professionally built project, the contractor should pull the permit in their own name. That does three things for you: it confirms the contractor is licensed to work in your city (most metro cities require contractor licensing before they'll issue a permit), it puts responsibility for passing inspections on the professional rather than on you, and it creates a public record that the work was done right.
A contractor who asks you to pull a homeowner permit for work they are doing is waving a red flag. It usually means they can't get licensed in your city, and it quietly shifts code liability onto you. Permit practices are one of the quickest ways to separate pros from pretenders; our guide on how to choose a remodeling contractor in Kansas City covers the other credentials worth verifying before you sign anything. And if you're planning something bigger, like a room addition, permit handling should be built into the contract from day one.
Project-Specific Permit Guides
Two projects generate more permit questions than everything else combined, so we wrote dedicated guides for them: our breakdown of basement finishing permits and egress window code covers bedroom egress, ceiling heights, and the basement inspection sequence, and our guide to deck permits and code requirements in Kansas City covers footing depth, railing height, and ledger attachment rules.
A note on accuracy: Code editions, permit fees, and exemption thresholds change, and each of the metro's dozens of jurisdictions adopts its own amendments. This guide reflects our best understanding as of August 2026, but it is general information, not a code ruling for your property. Always verify current requirements with your local building department before starting work.
Frequently Asked Questions
Do I need a permit to remodel my kitchen or bathroom in Kansas City?
Usually, yes. Swapping cabinets, countertops, paint, and flooring in the same layout generally does not require a permit in Kansas City, Missouri. But the moment you move or add plumbing, move or add electrical circuits, remove or alter walls, or relocate fixtures, you need a building permit and often separate trade permits. Most full kitchen and bathroom remodels cross that line.
How do I apply for a building permit in Kansas City, Missouri?
Kansas City, Missouri handles all permit applications electronically through its CompassKC online portal. For a residential remodel you submit a written scope of work plus existing and proposed floor plans. Trade work (electrical, plumbing, HVAC) requires separate permit applications, typically pulled by licensed contractors. Questions go to the Permits Division at (816) 513-1500.
How much does a building permit cost in the Kansas City metro?
Most metro cities calculate permit fees from the project valuation, so there is no single number. As a rule of thumb, typical residential remodel, deck, and basement-finish permits run roughly $100-$500 in most Kansas City area cities, with plan review sometimes billed separately. Large additions cost more because the valuation is higher. Always confirm with your city before budgeting.
How long does it take to get a permit in Kansas City?
Simple residential permits (decks, basement finishes, interior remodels) are often reviewed in a few days to two weeks in most metro cities, and some suburbs issue same-day permits for simple scopes. Additions and structural projects can take two to six weeks depending on review workload and whether the city asks for plan revisions. Build the review time into your project schedule.
What happens if I remodel without a permit?
The city can issue a stop-work order, charge investigation fees or doubled permit fees, and require you to open up finished walls so inspectors can see the work. Unpermitted work also follows the house: sellers in Missouri and Kansas must disclose known unpermitted work, buyers and appraisers discount it, and insurers can deny claims tied to uninspected electrical or plumbing.
Who is responsible for pulling the permit, me or my contractor?
On a professionally built project, your contractor should pull the permit in their name. That puts responsibility for code compliance and inspections on the licensed professional doing the work. Be cautious of any contractor who asks you to pull an owner permit for work they are performing; it can shift liability to you and is a common sign the contractor is not licensed in that city.
Do all Kansas City suburbs have the same permit rules?
No. The Kansas City metro includes dozens of jurisdictions across two states, and each city adopts and amends its own building codes and permit thresholds. The broad strokes are similar because most cities use the International Residential Code family, but fees, exemptions, and submittal requirements differ. Always check the building department for the city the property actually sits in.
What inspections happen during a remodel in Kansas City?
A typical remodel gets rough-in inspections (framing, electrical, plumbing, HVAC) after systems are installed but before insulation and drywall cover them, sometimes an insulation inspection, and a final inspection when the work is complete. Footing inspections are added for decks and additions before concrete is poured. Work covered before inspection may have to be opened back up.
