Spring is an ideal time for home improvements. Before beginning any home or construction project, it is important to verify whether a building permit is necessary. Permits help ensure that the work meets city safety standards and complies with building codes and regulations.

When Is a Permit Needed?

• Interior and exterior remodeling
• Window or roof replacement
• Structural changes
• New construction
• Commercial tenant improvements
• Business signage

If you’re unsure whether your project needs a permit, it’s best to contact the city before you begin.

Own a Historic Property?
If your property is a designated landmark or located in a historic district, you’ll need a Certificate of Appropriateness (COA) before making any exterior changes. This helps preserve the historic character of your property and neighborhood.
