Requirement for a Building Permit
A building permit is usually required whenever a structural changes is made to a residence (demolition or construction of new walls, or addition of a bay window). Permits are required for the construction of new homes or additions to an existing home. Permits are also required for many "home improvement" projects like fences, decks, sheds or cisterns. A demolition permit is necessary when completely removing a fixed structure from a property.
