Whether you are replacing your countertops, adding a wood floor, installing a window, replacing the backsplash or converting from a gas stove to an electric model, don't assume you do not need a permit. In some areas, even what seems to be a small project may need a permit. Also, don't expect your contractor to acquire the necessary permits since he may expect you to.
Permits help ensure that the remodel is done to current building code, either by you or your contractor. If you don't get the proper permits, you may be ordered to stop your remodeling project and be fined. In addition, government officials may require you to remove some of the work already done so inspectors have access to hidden systems, such as plumbing and electrical work. In addition, if you later sell your home, you might run into issues if the work was not done with the proper permits. Your home could be valued less, as well, if your kitchen remodel did not have the proper permits on record.
If you are replacing a tile floor or widening a window, you will likely need a building permit. If you are moving the kitchen sink or making other plumbing changes, including repairing or updating the plumbing, you may need a plumbing permit. If you are adding or moving light fixtures or making other electrical changes, you'll likely need an electrical permit.
Contact your local town hall or city or county planning and building office to obtain the proper permits for your kitchen remodel. Fill out the permits as directed and submit them to the corresponding address or office. You will also need to pay permit fees, which are submitted at the same time as the permits. Do not start work until you are given certificates of the permits required for the project.
