New Hampshire, Cheshire County Remodeler Permit Regulations and County Ordinances for Unincorporated Areas

In New Hampshire, building permit requirements are primarily determined at the municipal level, though all towns must adhere to the State Building Code (RSA 155-A), which adopts versions of the International Building Code (IBC) and International Residential Code (IRC). Cheshire County, like other areas in New Hampshire, relies on individual towns and cities to administer their own permitting processes.

1. Cheshire County's Building & Safety Division (Authority Having Jurisdiction)

New Hampshire does not have a statewide building code enforcement office. Instead, each municipality is responsible for issuing building permits and enforcing codes through its building department or code enforcement officer (CEO). For Cheshire County, this means that the specific "Authority Having Jurisdiction" will be the building department of the town or city where the property is located. While Cheshire County has a Safety Department that ensures a safe workplace and manages safety protocols for county facilities, it does not appear to be the primary authority for issuing building permits for private property renovations.

2. Rules for Properties in Unincorporated Areas

In New Hampshire, unincorporated areas may not have local building code enforcement officials. In such cases, the State Fire Marshal's Office is responsible for enforcing the state building code. However, this does not exempt property owners or design professionals from meeting the requirements of the NH State Building Code.

3. Specific Permit Triggers for Demolition Work During a Remodel

Demolition work during a remodel generally requires a permit. This includes the demolition of primary structures, accessory structures with utility or mechanical systems, or any addition/renovation that involves a substantial amount of demolition. Even interior demolition where the intent is to renovate or change the structure typically necessitates a permit. Some minor demolitions, like sheds or decks, may be exempt, but it's crucial to verify with the local building department. An asbestos report may also be required.

4. Permit Requirements and Definitions for Altering or Converting Non-Living Spaces

Converting non-living spaces such as garages, attics, or unfinished basements into habitable living areas almost always requires a building permit. This is because such projects involve structural changes, alterations to occupancy type, and the creation of new habitable space.

Garages: Converting a garage into living space typically requires a building permit, as it involves structural changes and often the addition of plumbing and electrical work. This is considered a change in occupancy type.
Attics: Finishing an attic into habitable space, such as bedrooms or offices, requires a permit. Habitable attics must meet specific egress requirements, including vertical access (stairs or ramp) and an emergency escape and rescue opening.
Basements: Finishing an unfinished basement into habitable space also requires a permit. This includes ensuring adequate light and ventilation (often through windows or mechanical systems), proper heating, insulation, combustion air for fuel-burning appliances, and emergency escape and rescue openings. Minimum ceiling heights are also specified.

In all cases of converting non-living spaces, the new areas must comply with current building codes, including electrical, plumbing, energy efficiency, and structural standards. Detailed plans, often prepared by a licensed architect or engineer, may be required.

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.
