The Codes require that “No building, structure or service equipment shall be erected, constructed, enlarged, altered, repaired, moved, improved, removed, converted or demolished unless an appropriate permit has been obtained from the Building Official.” There are some exceptions where a permit is not required. The exceptions include: painting, papering, stucco repair, counter and partitions not over five feet high, replacement of plumbing fixtures where no modification is necessary to the water or sewer piping, and portable electrical appliances energized by a cord or cable having an approved factory attached plug end. As an example, a permit is required for replacement of windows and water heaters, but removal and re-installation of dishwashers, garbage disposals, and water closets is exempt.
