Project questions
Frequently asked questions for Leavenworth County
Who handles permitting for this jurisdiction?
Leavenworth County Planning & Zoning Department / Director of Planning & Zoning as Building Official is the identified county-level authority for this profile. Confirm that the property is in its service area before filing.
How should I begin an application?
Begin with the online permit gateway listed in the application guide. If the portal does not recognize the address or project type, contact 913-684-0465.
How long might review take?
Allow 5-10 business days after the county confirms the building-permit packet is complete. The older zoning/subdivision regulations also state that building-permit applications must be approved or rejected within seven days of submittal; the county’s current public permit guidance publishes the 5-10 business-day estimate. A permit is valid for one year from issuance.
How are inspections scheduled?
The public permit materials do not publish a separate inspection-booking calendar. The 2025 building-code resolution authorizes the Building Official to accept written inspection reports from approved agencies or individuals. Contact Planning & Zoning at 913-684-0465 for inspection instructions and project-specific requirements. Do not begin construction before permit approval.
Which codes and exemptions should I review?
Resolution 2025-37, adopted November 12, 2025, adopts the 2012 International Residential Code for one- and two-family dwellings and the 2012 International Building Code, with county amendments and omissions, throughout the unincorporated area. The resolution applies to new residential and commercial construction; new construction includes work replacing, reconstructing, repairing or adding to an existing building when 51% or more of the building is involved. It repeals Resolution 2020-39 and includes local provisions such as a 200-square-foot exception, a 51%-repair threshold, and adoption of specified appendices. Structures under 100 square feet are not regulated. The county’s published guidance lists roofing, roof-mounted solar panels, deck replacements in the same footprint, unenclosed carports and interior modifications as not requiring a building permit. Resolution 2025-37 states that repairs constituting less than 51% of the building structure do not require a permit. Agricultural accessory-building permit fees are $0 under the published schedule but require compliance with zoning/subdivision regulations and agricultural-exemption approval; this is a fee exemption, not a blanket exemption from county review.
