The CIty of Winchester contracts with Ballwin to review, approve and perform the necessary inspections for building permits.  You will need to go to Ballwin City Hall at #1 Government Center to complete the application, pay their fee and obtain the permit when it is required.   

BUILDING PERMIT COST - The fee for a building permit depends upon the type of project, the number of inspections required, and the cost of the project.  A certificate of insurance or construction bond may also be required. 
Reminder:  Municipal Code stipulates that building permit fees are doubled if work begins before a permit is secured. 

PERMIT DEPOSIT - Residential and commercial permit applications require a non-refundable deposit.  Upon Building Department approval of your application, the deposit will be credited to the total cost of your permit.  If the Building Department does not approve and issue a permit, the deposit will help cover the Building Commissioner's fee for review of the plans.
