Bangkok declared all 50 districts a disaster zone, effective 25 September 2026. Relief requires a district survey and a victim certificate (หนังสือรับรองผู้ประสบภัย) before aid is assessed. Report damage at your district office, then keep photos or video of the building, stock and work tools, plus your ID, house registration and ownership papers. Relief is paid on actual damage, not a flat rate: building repair up to 49,500 baht, work-capital up to 11,400 baht if tools are unusable, rent support up to 3,000 baht a month for up to 2 months if the home is wholly damaged. Hotlines: BMA 1555 or Traffy Fondue.
