Many new home buyers/owners are asking if building permits are really necessary for various home upgrades. The main purpose of building permits is the safety of the inhabitants and the immediate neighboring structures. A building permit may be required when a residential structure or portion within a structure is erected, constructed, enlarged, altered, repaired, improved, removed, converted, moved, or demolished. Some examples of when a permit is required may include the following:
installation of a new roof;
adding or blocking off a door or window;
adding or relocating electrical outlets;
adding or relocating plumbing fixtures, such as showers, sinks or toilets;
converting a garage or storage area to an air-conditioned, occupied area, or installation of central air-conditioning systems; and
Other minor changes such as adding a sink disposal or dishwasher.
