  • Finishing Your Basement Does Require A Permit
    In most cases you will also have to obtain mechanical, electrical and plumbing permits. Finishing your basement can increase the comfort and value of your home. With the assistance of the Ballwin Code Enforcement Department, you can make sure that your project is done in a safe and code-compliant manner At some point in the future, should you want to sell your house, it will have to be inspected and approved by the City of Ballwin. If you do not get a permit for a basement finish, you will have to obtain a building permit and approval before the house can be sold. This may mean that some demolition will have to take place so that the necessary inspections can be made. It is much easier to get the permit when the work is done.
