Traditional building permit applications can be found in the document center or can obtained in-person from our office. Completed application packets can be submitted in-person, emailed to us at PZ@LeavenworthCounty.gov, or submitted through our new Building Permit Online Application.

After receiving a building permit packet, we will confirm that the application is complete. Please then allow for 5-10 business days for the application to be processed. Once the permit is complete our office will be in contact with the applicant to arrange payment which can be done by check, in cash, or over the phone via credit/debit card. PLEASE NOTE: there is a fee associated with processing credit/debit cards charged by the service provider that is a percentage of the overall cost.

For more information regarding associated fees, please refer to our Schedule of Fees.


Additional Information:

  • Before beginning construction, please contact Kansas811 to determine where underground utilities are located on your property.
  • When a parcel requires an entrance and is not being obtained at the same time as a Single Family Residence, an Entrance Permit Application will need to be submitted. More information about entrance permits can be found here.
  • In order to submit a building permit packet, the applicant will need to be on the deed of the property. If someone other than the owner of the property is submitting a building permit packet, an Owner Authorization form will need to be submitted with the packet.
