9A.52.010

(1) "Building" in addition to its ordinary meaning, includes any dwelling, fenced area, vehicle, railway car, cargo container, or any other structure used for lodging of persons or for carrying on business therein, or for the use, sale or deposit of goods; each unit of a building consisting of two or more units separately secured or occupied is a separate building.
(2) "Dwelling" means any building or structure, though movable or temporary, or a portion thereof, which is used or ordinarily used by a person for lodging.
(3) "Enters or remains unlawfully." A person "enters or remains unlawfully" in or upon premises when he or she is not then licensed, invited, or otherwise privileged to so enter or remain.
A license or privilege to enter or remain in a building which is only partly open to the public is not a license or privilege to enter or remain in that part of a building which is not open to the public. A person who enters or remains upon unimproved and apparently unused land, which is neither fenced nor otherwise enclosed in a manner designed to exclude intruders, does so with license and privilege unless notice against trespass is personally communicated to him or her by the owner of the land or some other authorized person, or unless notice is given by posting in a conspicuous manner.
(4) "Premises" includes any building, dwelling, structure, real property, or any real property fenced or otherwise enclosed or posted in a manner designed to exclude intruders.
