Permit & Structure FAQs
- What is a Building Permit and why do I need one?
A Building Permit is the first step to making any change to property you own. This permit is issued from the Town and allows the building process to begin. The Building Permit process allows you to know that your project is built to code, inspected, and legally recognized by the Town so you can live in your home with peace of mind that it has met all safety and legal standards. In addition, by working with the Town to achieve compliance, you will obtain a Certificate of Occupancy (CO), which home owner's insurance and mortgage companies require. You must have a CO before you can live in this structure. Structures that are built without a building permit are subject to fines. A Building Permit is a formal written approval, stating all requirements and it is subject to various inspections by the Town allowing you to, in any way, alter property that you own.
