Thailand's Department of Public Works and the Bangkok governor's office are drafting zoning and building rules for data centres. Large facilities would be limited to designated zones; small and medium ones could go in residential, commercial, rural or industrial zones with setback and coverage conditions. Electricity and water use criteria are still under discussion, and the Energy Ministry may set power or solar requirements. For most SME owners this is a background change: it matters mainly if you plan to lease land or buildings near data centre projects, or supply them.
