Modular Buildings


The Modular Building Program was created in 1993 and has been in effect since July 1, 1993. The program was established in conjunction with various modular building manufacturers, third party inspection agencies, local and state code enforcement officials. The goal of the program is to assure modular construction is built in accordance with the codes and standards adopted at the state level. Compliance with the program is witnessed by the application of New Hampshire modular labels on each unit.

Modular manufacturers are approved by the State Fire Marshal’s Office. The manufacturer must also have an approved third party inspection agency. The third party inspection agency has architects and engineers on staff to review and approve construction plans, as well as inspectors who perform in process inspections of each unit. The State Fire Marshal’s Office audits the third party inspection agencies and manufacturers on an on-going basis in an attempt to assure product quality and code compliance.

These procedures are in place to take the inspection burden from the local officials and end users. The presence of New Hampshire modular building labels on the units certify the units meet the codes and standards adopted at the state level.
