    Obtain a building permit from the Bangkok Metropolitan Authority

    Agency: Bangkok Metropolitan Authority

    As of April 1, 2013 the Bangkok Metropolitan Administration (BMA) now allows district directors to act on behalf of the Bangkok Governor under Building Control Act B.E. 2522 (1979) for simple buildings. The district director can issue the building approval for buildings that are not more than 10,000 sq. m. and not taller than 23 meters. This fast-track option has significantly reduced the time to obtain the building permit.

    Notify the Bangkok Metropolitan Authority on the commencement of construction works

    Agency: Bangkok Metropolitan Authority

    After the building permit has been granted, the name of the construction supervisor must be given to the Bangkok Metropolitan Authority with the permission of that supervisor. The latter could be any qualified person, including the building owner, unless that person is prohibited by the regulations of the Engineering or Architectural Profession Act.

    It is assumed that one of BuildCo’s employees or owners satisfies the requirements for being a construction supervisor. It is common for the supervisor to be the owner or one of the employees of the construction company. The construction supervisor should verify building conditions periodically.

    BuildCo must also submit a notification to commence construction works.
