A plumbing permit is a permit issued for plumbing jobs in accordance with local and national plumbing codes. The purpose of these permits is to ensure that plumbing systems are installed in a manner that is safe and addresses the welfare of the inhabitants of the building in question and the local community.

Permits also ensure local tradespeople, who work hard for their licenses, are protected and that the county also makes some money because of it.

Your home is a major investment, and one that you’d want to protect. If in the future, you want to sell your home, getting plumbing permits for major plumbing jobs is proof for your potential home buyer that every plumbing repair and modification to the home was done in accordance with the law.

Otherwise, you may find yourself in trouble if the buyer were to schedule an inspection prior to closing the sale.
