Laws affecting the use and possession of land itself fall under the umbrella of "land use laws." Sometimes land you own may be used by someone who does not legally own or possess your land. This may include public entities, such as the government or city workers, or individuals who may frequent the land in a variety of settings, such as mail carriers, service workers, and even trespassers. There are special rules concerning land use in all states. This section provides information and resources on a variety of land use matters, including easements, eminent domain, trespassing, and zoning.
