RSA 48-A:11: Minimum Standards; Barring the Use or Occupancy; Violations and Punishment.

Any municipality may (by ordinance adopted by its governing body):

I. Prescribe minimum standards for the use and occupancy of dwellings throughout the municipality;

II. Prevent the use or occupancy of any dwelling which is injurious to the public health, safety, or welfare.

III. Enact, in the sections of their housing codes dealing with infestations of insects, provisions directed at the unique problems posed by infestations of bed bugs, provided that such provisions are no less protective of the residents of dwelling units in which bed bug infestations are found than are the provisions dealing with infestations of other kinds of insects.
