New ministerial regulations came into effect on 3 July 2010 to control land utilisation and development in the Kok Gloy and Tai Muang areas of Phang Na. The regulations have divided the area into ten zones in which restrictions and requirements for land utilisation in each zone vary. Most beachfront land in the area has been designated as forest conservation or agricultural zones, limiting new projects to single housing, government buildings or government infrastructure.

Individuals and/or developers are urged to conduct comprehensive due diligence exercises if new land is sought in one of the designated zones. The regulations are effective for 5 years.
