Building Code

The Building Inspector reviews plans for the construction or alteration of buildings / structures for compliance with a number of codes. The Town has adopted a Building Code Ordinance (PDF) which summarizes the different codes enforced by this office. Copies of these codes are available for use in the Planning, Zoning and Codes office.

Prior to the construction or alteration of any building or structure, it is necessary for the property owner to obtain a building permit from this office. Link to application forms.

When applying for a building permit it is necessary to provide complete plans of the work proposed. For one- or two-family residential projects, submission requirements may include:

  • Floor plans and elevations
  • Electrical plans showing lights, switches and receptacles as well as detailed information on services and feeder circuits
  • Plumbing plans. Plumbing fixtures should be shown on the floor plans. A riser diagram of the drains and vents is also required
  • Heating system data including venting details
  • Fireplace and chimney details
  • Information demonstrating compliance with the NH. Energy Code including insulation of the entire building, window insulation values and areas of windows as a percentage of the wall area of the building
  • Second means of escape provisions as required by the Life Safety Code
  • Smoke detector locations
  • Approved Driveway Permit
  • Approved Septic System Permit
  • Plan showing well location

Commercial / multi-family projects often require plans prepared by a registered architect or engineer. Submission requirements may include the following:

  • Architectural
  • Structural
  • Mechanical
  • Electrical
  • Fire alarm
  • Fire suppression
  • Site work

Building permit fees depend upon the type of permit (One- and Two-Family Projects vs. Commercial / Multi-family Projects) and scope of work. See the Town of Hanover Rate and Fee Schedule for current charges.

Once a building permit is issued, the permit card must be displayed on the project site where it is visible from the road.
