State Building Permit Program

The NH State Fire Marshal’s Office administers the state building permit program, providing building code enforcement and periodic inspections for all state-owned property. We also provide technical code assistance to local fire departments.

This program covers the permitting, plan review and inspections for all construction work, including temporary places of assembly, such as tents.

It applies only to construction that meets at least one of the following criteria:

  1. State owned property
  2. Community college system property
  3. Municipal projects for which we have received a written request for assistance
  4. Projects in municipalities without a code enforcement mechanism, from whom we have received a written request for assistance

Permits are required for new and renovation construction based on the provisions of the current NH State Building Code and applicable amendments.

Types of Permits

  • Building
  • Mechanical (fuel-gas) – Applies to all work subject to state licensing requirements as identified in RSA 153:27
  • Mechanical (non-fuel gas) – Applies to work not subject to state licensing requirements, including ductwork
  • Electrical
  • Plumbing
  • Fire Protection: Includes fire suppression systems, fire alarms, kitchen and exhaust systems.

Permit & Inspection Process

  1. Separate permit applications and applicable payment are required for each permit at least 30 days prior to the intended start of construction. Application materials, forms and documents are located in the searchable library.

    Additional supporting documents are as follows:

    1. One set of construction documents, if not already submitted and approved by this agency. Pursuant to RSA 153:8-a,I
    2. A completed Statement of Special Inspections, if applicable
    3. All other supporting documents required by the NH State Building Code
  2. At the time of submission, one set of plans shall also be submitted to the local AHJ for their review and input.
  3. Application Review:
    If the application, construction documents or supporting documents do not conform to the requirements of statutes, rules, or state and local adopted building codes, the fire marshal or designee shall deny the application in writing within 30 days of receiving an application, stating the reasons therefor. If the fire marshal or designee approves the application, the permit shall be issued as soon as practicable and shall be posted on the project site for the duration of the construction.
  4. Required inspections need to be scheduled 48 hours in advance by contacting this office at 603-223-4289 Option 1. For all plumbing and fuel gas inspections contact the inspector assigned to your project.
  5. If inspected work in place is found to be not in compliance with applicable state building codes at the time of inspection, the inspector shall issue a written order to the permit holder to correct the non-compliant work. The corrected work shall be subject to a re-inspection to verify compliance, and the permit holder shall be subject to a re-inspection fee.
  6. Upon completion of the work, inspections for compliance with state and local codes by the fire marshal or designee and receipt of required documentation, a certificate of occupancy shall be issued.
