Permitting: Commercial

Effective 11/1/2015, ALL Commercial Permit Applications must be completed online

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. Project plans should be submitted to Johnson County Wastewater at the same time 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 Johnson County Wastewater Permit Site Plan and other project drawings.

Once all required documents are provided to the department, please allow up to 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 in which 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) occurs, Johnson County Wastewater requires the property owner and/or tenant to complete an application and submit construction plans for review by Johnson County Wastewater. A Johnson County Wastewater permit is required in all locations where a new water utility meter is installed, the water utility meter size is increasing, and for food service facilities. The documents included on this page are provided to guide the property owner, building owner, engineer, contractors, and tenant through the permitting process and to identify the requirements for Johnson County Wastewater's Commercial Permit Site Plan and other project drawings. Once all required documents are provided to Johnson County Wastewater, please allow 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 in which they are received.

Commercial Project Fees - Fee Change is Effective January 1, 2017

Effective Jan. 1, 2014, sewer connection fees are based on the water meter size for each building or tenant space as issued by the water utility (e.g. WaterOne, City of Olathe, BPU, et al). The Johnson County Wastewater connection fee schedule applies and customers are required to obtain a sewer connection permit for all new water meters or when a water meter size increases. Fees are due to Johnson County Wastewater at the time the meter or meter size change permit is issued by the water utility. Fees for meter size increases will be calculated as the difference in fee between the existing meter and the new meter. The $220 Johnson County Wastewater permit fee, the $440 commercial review fee, additional special inspection fees, and/or grease permit fees continue to be charged for permits as applicable.

Connection Fees: The 2017 connection fee schedule by meter size is as follows. This schedule does not include the $220 permit fee, special inspection fees, or grease permit fees. Please contact a Johnson County Wastewater Commercial Plan Reviewer at 913-715-8520 to discuss meter fees when the meter is larger than two (2) inches and the size is required to accommodate water-in-product or cooling tower makeup water.

Permit Execution Requirements

Johnson County Wastewater permits shall be issued to the Property Owner. The Property Owner may sign the permit or may authorize another individual to pick up and sign the permit on the Owner’s behalf. The Owner must provide the company name(s) and individual’s name(s) for permitting. The individual authorized to execute the permit is responsible for providing a copy of the permit and all associated documentation to the Owner.
 
By authorizing another individual to execute the permit on the Owner’s behalf, the Owner acknowledges the following understanding in addition to all conditions of the permit:
The Owner understands and acknowledges that connection fees assessed pursuant to the Johnson County Wastewater Sewer Use Code (the Code); are assigned based on the water meter size and use of the building as it is designed at permit issuance and when a new meter or existing meter size is changed by the water utility or if the use, expansion or modification to the building occurs for tenant finish, the plans must be submitted to Johnson County Wastewater for review. Based upon that review, a Modified Use Permit may be required that could result in the assessment of additional connection fees.  Upon completion of the review process, the Owner remains responsible for the payment of any additional connection fees associated with the Modified Use Permit and satisfaction of any conditions contained in the permit.
 
The Owner further understands and acknowledges that if a Modified Use Permit is not obtained and additional connection fees paid prior to the issuance of a City or County Occupancy Permit, the additional permit fees are considered delinquent and shall be assessed and collected (plus interest) in the manner provided by the Code and applicable Kansas law.
