Commercial Building Sanitary Sewer Permitting
New Commercial Building Construction
To acquire a building permit for a new commercial building (including multi-unit residential) in Johnson County Wastewater’s service area, a Sanitary Sewer Connection Permit must first be issued to the Property Owner from Johnson County Wastewater (JCW). Project plans should be submitted to JCW when they are submitted to the City for building permitting. The following documents are provided to guide the Property Owner, Building Owner, Engineer, Contractors and other interested parties through the Commercial Building Sanitary Sewer Connection permitting processes and to identify the requirements for the JCW Permit Site Plan and other project drawings. Once all required documents are provided to JCW, please allow up to fourteen (14) calendar days to receive initial review comments. Please allow up to seven (7) calendar days to receive comments for all subsequent reviews until permit issuance. Reviews are completed as quickly as possible in the order they are received.
Tenant Finish, Building Expansion, or Change of Use for Commercial Buildings
For building expansions or tenant finish of existing building space(s), where a change of use, expansion or modification to an existing building use occurs, JCW requires the Property Owner and/or Tenant to complete an application and submit construction plans for the issuance of a Modified Usage Permit. The Modified Use permit shall be issued to the Property Owner. The following documents are provided to guide the Property Owner, Building Owner, Engineer, Contractors, and Tenant through the Modified Use permitting process and to identify the requirements for the JCW Commercial Permit Site Plan and other project drawings. Once all required documents are provided to JCW, please allow fourteen (14) calendar days to receive initial review comments. Please allow seven (7) calendar days to receive comments for all subsequent reviews until permit issuance. Reviews are completed as quickly as possible in the order they are received.
Commercial Project Fees
JCW determines fees for commercial projects (including new construction, tenant finish, building expansion, of change of use ) by JCW usage type categories and the size of the building space. JCW must review project drawings and the completed commercial application for the project to verify fees. Please contact the JCW Permit Group at 913-715-8520 for additional information.
