New Hampshire Remodeler Legislation, Codes, and Guidelines

New Hampshire Building Codes for Remodelers and Residential Renovations

New Hampshire adopts and enforces building codes based on the International Code Council (ICC) model codes. The primary codes relevant to remodelers and residential renovations are the International Residential Code (IRC) and the International Building Code (IBC), often with state-specific amendments.

1. Adopted State Statutes and Codes

New Hampshire has adopted the 2018 International Residential Code (IRC) and the 2018 International Building Code (IBC).
The state also adopts the International Fire Code (IFC) and the International Mechanical Code (IMC), among others.
While the International Existing Building Code (IEBC) is a model code, New Hampshire's approach to existing buildings is primarily addressed through the adopted IRC and IBC, with specific provisions for alterations, repairs, additions, and changes of occupancy.
Specific amendments and adopted codes can be found within New Hampshire's state statutes, particularly RSA 155-A.

2. Primary State Board or Agencies

The **New Hampshire Department of Safety, Division of Fire Safety, Bureau of Building Codes and Standards** is the primary state agency responsible for adopting, administering, and enforcing the state building codes.
Local building departments within municipalities are typically responsible for plan review, permitting, and inspections for most residential renovations.

3. Classification of Remodels and Demolition Guidelines

New Hampshire's codes generally distinguish between cosmetic improvements and structural alterations. Cosmetic remodels, such as painting or replacing flooring, typically do not require permits unless they involve changes to electrical or plumbing systems.
Structural alterations, including the conversion of attics or basements into habitable living spaces, additions, or significant changes to the building's structure or egress, will require permits and must comply with the current adopted codes.
Demolition guidelines are addressed within the adopted codes, particularly concerning safety during demolition, environmental concerns (like asbestos abatement), and the proper disposal of debris. Specific demolition permits are usually required, and the process often involves notifying utility companies and adhering to local ordinances.
