    Last updated: February 2026

    Introduction to Construction & Building Law

    Thailand's construction and building sector is regulated primarily by the Building Control Act B.E. 2522 (1979), which establishes building codes, permit requirements, and safety standards. The Engineering Act B.E. 2542 (1999) and Architecture Act B.E. 2543 (2000) regulate professional licensing. Construction contracts are governed by the Civil and Commercial Code. Key concerns include building permits from local authorities, compliance with fire safety and earthquake-resistant design standards, and contractor licensing. Foreign construction companies face additional restrictions under the Foreign Business Act but can operate through BOI-promoted structures or joint ventures.
