When do I need a building permit?

You need to obtain a building permit for new construction or for altering existing construction. You generally do not have to obtain a building permit to make repairs, although there are exceptions to this rule. Additions, finishing an attic or basement, or changing interior walls are examples of alterations that require a building permit. A wood-burning stove or an indoor hot tub may also require a building permit. In addition, exterior additions such as a deck, pool, fence, shed, or garage require a building permit.

The following are examples of work requiring a building permit. Note, this is not an all inclusive list:

  • New construction
  • Alteration of an existing building
  • An addition to an existing building
  • Change in use of a building
  • Cutting of part or all of a wall or partition
  • Removal or cutting of any structural beam or bearing support
  • Removal or change of any required means of egress
  • Work affecting structural or fire safety
  • Work that increases the non conformity of an existing building
  • Work that affects public health or safety
