Each May, we celebrate Building Safety Month. Getting a building permit is one of the best ways you can keep yourself, others and your property safe during and after a project.

  • Demolition
  • Driveway approach and public sidewalk

  • Retaining walls
  • Fire repairs
  • Furnace and air conditioner replacements
  • Mechanical or plumbing alterations
  • Re-roofing
  • Remodeling
  • Swimming pools, hot tubs and spas
  • Water heater replacement

When don’t I need a permit?

Permits are not needed for cosmetic changes, like painting, cabinetry, carpeting, siding, lawn sprinklers and landscaping improvements.

How do I apply?

Applying for a building permit is easy at Before you apply, make sure you have basic information ready like a description of the project and the materials you plan to use.

Some projects, like decks, fences, sheds, additions, and swimming pools, require submission of a plot plan with your application showing an outline of the project drawn to scale. For decks, swimming pools, and residential additions, construction drawings are needed, too.

At, you’ll find resources to help you with your project, like project-specific guides and information about inspections.
