Do I Need a Permit to Replace Windows in Leawood, KS?

Last updated: September 18, 2026

Leawood exempts residential window replacement when no structural modifications are made. City Code §4-905, which amends IRC R105.2, lists “Window replacement where no structural modifications are made” under work exempt from a permit. Enlarging an opening or changing structural framing falls outside that exemption. Identify the actual work before deciding whether your project qualifies.

The source is the Leawood City Code, §4-905, Building item 6 (PDF page 183), reviewed September 18, 2026; the published code is marked updated September 14, 2026. The same section says permit exemption does not excuse code violations. This residential-code provision should not be assumed to govern a commercial or multifamily project.

Which window projects fit the exemption?

The key distinction is structural modification, rather than the number of windows or a contractor's marketing name for the installation. Use this scope worksheet to prepare a conversation with your installer and, where the scope is unclear, the city.

This is a planning checklist, not a substitute for the city's project-specific interpretation. If concealed damage changes the work, reassess the scope before proceeding with structural repairs.

Who handles permits and project questions?

Leawood Code Services / Building Permits identifies Codes Administration as responsible for plan review, permits and inspections. The published building-permit phone is 913-663-9165. Use the city website to confirm current contact information.

Start by confirming the property's actual jurisdiction. A mailing address, contractor's service area or nearby city's rules should not determine which office handles a project. For a Leawood property, use Leawood's requirements rather than assuming a neighboring city's process applies.

What information should I prepare before asking the city?

Create a one-page scope record with your installer:

• Property address and type of building.
• Number of openings and a room-by-room list, noting bedrooms.
• Photos of the interior, exterior and visible damage.
• Existing and proposed dimensions and operating styles.
• Insert or full-frame installation method for each opening.
• Whether headers, studs, opening size or other structural members will change.
• Whether the work includes an addition or other remodeling.
• Who will apply for any required permit and coordinate inspections.

A useful question is: “Our proposed residential project replaces these windows with the attached scope. No structural modifications are planned at these openings; these other openings involve the framing changes shown. Which portions require a permit, and what documents and inspections apply?” Keep the city's response with the final scope so later revisions can be checked against it.

Applying when the project requires a permit

The city links applications through Access Leawood. Follow the current instructions for the relevant permit type. Before setting an installation date, clarify what documentation is needed, who submits it, how fees are calculated for that scope and which inspection stages apply.

Do not budget a generic percentage of the window price as a confirmed city fee. Ask for the applicable fee or calculation and show it separately from the contractor's administrative charge, if any. Likewise, a general permit processing estimate is not a promised approval date for your project. Review completeness and structural details can affect the sequence.

For inspections, establish who schedules them and whether any work must remain visible for review. Keep application details, issued documents, inspection results and closeout records together. If the city requests corrections, get the actual correction list rather than relying on a paraphrase.

What should the contractor's quote say?

The written scope should distinguish exempt nonstructural replacement from work that needs municipal review. It should assign responsibility for applications, fees, inspection scheduling and addressing corrections where applicable. Homeowner participation in paperwork is not, by itself, evidence of poor workmanship or improper licensing; clarify the responsibility and verify the applicable requirements.

Ask which city or county license categories apply to the work and how to verify them. Do not assume one license description covers every trade or project. Use the city's current Codes Administration information as the starting point.

For hidden deterioration, agree on a stop-and-document process: photographs, proposed repair, price or pricing method, written homeowner approval and any necessary city review. A nonstructural replacement can become a different project if damaged structural framing needs repair.

HOA approval is a separate question

A city permit exemption does not answer whether your property's covenants require architectural approval. Read the association's current documents and submission instructions. Ask specifically about exterior color, frame material, glass appearance, grid pattern and changes to opening proportions.

Prepare product sheets and exterior elevations or photos as requested. Obtain the applicable association decision before placing a nonreturnable order. There is no verified universal Leawood HOA turnaround time; use your association's actual review schedule. City approval and association approval address different requirements, so retain both records when both apply.

Frequently asked questions

Does replacing one window automatically require a permit?

No. For residential work covered by the cited provision, the distinction is whether structural modifications are made, not the number of windows. Describe any additional work before relying on the exemption.

Does full-frame replacement always require a permit?

The phrase alone does not establish whether structural modifications occur. Have the installer specify what is removed and changed. Obtain clarification from Codes Administration when the work goes beyond the clear nonstructural replacement case.

Can I change a bedroom window's operating style?

Check the applicable clear-opening and safety requirements before selecting the unit. The new product's nominal dimensions do not establish the size of its usable opening. A permit exemption does not waive code compliance.

How much is a window permit and how long will it take?

For work that needs a permit, obtain the applicable fee and current processing information from the city for the actual scope. This guide does not assign an unsupported flat fee, percentage or approval deadline.

What if hidden rot appears during installation?

Document it, identify whether the repair changes structural members, approve the written repair scope and confirm any municipal requirements before proceeding with that changed work.

Does this guide cover every Kansas City suburb?

No. It explains Leawood's cited residential provision. Other cities and other building types need their own current requirements checked.
