Temporary buildings refer to simple structures or facilities built and used temporarily by units and individuals for production or living needs, and which must be demolished within a specified period. Examples include shacks, work sheds, and short-term exhibition rooms (model rooms, exhibition rooms). Structurally, they must not exceed two stories, and except for special engineering requirements, durable structural forms such as cast-in-place reinforced concrete are generally not used.
The usage period of temporary buildings is legally mandated. According to the *Urban and Rural Planning Law* and the *Land Administration Law*, "The usage period of temporary buildings shall not exceed two years, and they shall be demolished by the owner within the approved usage period." Temporary buildings are not granted property rights certificates, and their use cannot be changed. If an extension is required due to special reasons, the construction unit must apply for an extension before the expiration date, and only one extension application is allowed. If the two-year period has expired without an approved extension, it is considered an illegal building.
