Permits are required for most of the improvements made to buildings and structures. Separate plumbing, electrical, and mechanical permits are required if such work is to be performed. The purpose of obtaining a permit is to allow the enforcement of the codes which have been adopted as law by the state.

The enforcement of these codes is carried out to protect the public health, safety, and welfare. As a homeowner or business owner, you have an investment in the property that will be built or remodeled, and it must comply with the codes. If not, your investment could be reduced. Therefore, a permit is used to notify the Code Official that you are constructing or remodeling a building so he or she can ensure code compliance. Some jobs may require a zoning clearance (i.e., decks or additions) before a permit may be issued.
