Modular Buildings
The modular construction safety inspection and certification program has been in effect since July 1, 1993. The goal is to ensure modular construction is built to state fire and building code standards.
Program Highlights
Manufacturers are approved by the State Fire Marshal’s Office. Then, a NH certification label is issued and affixed to each modular unit, indicating the manufacturer complies with these standards.
Each manufacturer must also have an approved third-party inspection agency.
This agency has architects and engineers on staff to review and approve construction plans, and inspectors who perform in-process inspections of each unit.
The State Fire Marshal’s Office audits the third-party inspection agencies and manufacturers to ensure product quality and code compliance. We also conduct
on-site inspections of modular buildings that are being set within New Hampshire.
These procedures are in place to remove the inspection burden from local officials and end users.
Builders & Dealers, please notify our office and local officials at least 72 hours prior to the erection of a modular building or building component within our state.
