Manchester, New Hampshire Remodeler Local Permit Ordinances and Codes
Manchester, New Hampshire Remodeling and Renovation Permit Ordinances
In Manchester, New Hampshire, most construction and renovation projects require permits before work can commence. The city adheres to New Hampshire state building codes and local regulations. The Planning & Community Development Department, specifically the Building Division, is the authority responsible for administering building codes, reviewing plans, issuing permits, and conducting inspections.
1. Authority Having Jurisdiction
The Manchester Building Department, part of the Planning & Community Development Department, is the Authority Having Jurisdiction (AHJ) for building permits and renovations. They can be reached at 1 City Hall Plaza, Manchester, NH 03101, or by phone at (603) 624-6450. Their office hours are Monday through Friday, 8:00 AM to 5:00 PM ET.
2. Demolition Permit vs. Building Permit Triggers
A distinct demolition permit is required for the full demolition of a building. Partial demolition involving the removal of structural elements, such as walls, roof sections, or floors, also necessitates a building permit. For smaller accessory structures built after 1978 and not in a historic district, a demolition permit might be exempt, but utility disconnection and proper disposal are still required. Structures built before 1978 may require an asbestos survey prior to demolition.
Generally, permits are required for:
- New construction and additions.
- Alterations, renovations, and repairs to existing buildings.
- Decks.
- Demolition.
- Signs.
- Trade work (electrical, plumbing, heating/cooling).
Minor cosmetic work, such as painting, wallpapering, tiling, carpeting, and cabinet/countertop installation, may not require a permit if it does not affect structural integrity or safety systems.
3. Converting Non-Living Spaces to Habitable Areas
Converting non-living spaces like basements or garages into habitable areas requires building, electrical, and plumbing permits. The conversion must meet all residential building code requirements for habitable space, including egress, insulation, ceiling height, and ventilation.
A landowner may not need a zoning permit to expand residential use into existing space (e.g., converting an unfinished basement or attic) if the number of dwelling units or bedrooms does not change. However, a zoning permit is required if the number of dwelling units or bedrooms will change.
4. Fee Nuances and Inspection Stages
Manchester building permit fees are typically based on the project's valuation and permit type. A non-refundable application fee of $25 is required for most permits.
For residential building permits:
- New 1-2 family dwellings: Estimated cost of work × 0.006 (minimum $30 permit fee if inspections are required).
- Alterations/renovations/repairs to existing buildings: Estimated cost of work × 0.010.
For commercial and multi-family buildings, the fee is generally the estimated cost of work × 0.010. A plan review fee of $0.02 per square foot is also assessed for multi-family and commercial applications.
Inspections are a crucial part of the process. Inspectors are available Monday through Friday from 7:00-8:30 AM and 3:00-4:00 PM. Inspection requests can be made via email, including the permit/application number and project address.
A Certificate of Occupancy or completion letter will not be issued until all inspections for all associated permits are approved and all supporting paperwork is submitted. Requests for Certificates of Occupancy and final inspections must be made in advance: five business days for one- and two-family dwellings, and ten business days for commercial projects or residential projects with more than three dwelling units.

New Hampshire, Hillsborough County Remodeler Permit Regulations and County Ordinances for Unincorporated Areas
Hillsborough County, New Hampshire Remodeling and Renovation Permit Requirements
Hillsborough County, New Hampshire, has specific requirements for remodelers and renovation permits, with the Building & Safety Division acting as the Authority Having Jurisdiction (AHJ) for unincorporated areas. It's crucial for property owners and contractors to understand these regulations to ensure compliance and safety.
Unincorporated Areas
In Hillsborough County, properties located in unincorporated areas fall under the direct purview of the County's Building & Safety Division for permit and inspection requirements. This means that standard municipal building departments may not be the primary point of contact for these locations.
Demolition Work Permits
Demolition work during a remodel in Hillsborough County typically triggers a permit requirement. This is to ensure that demolition is conducted safely, with proper environmental controls (like asbestos abatement if applicable) and structural considerations in place. Specific triggers often include:
- Any demolition that affects the structural integrity of the building.
- Partial or complete demolition of load-bearing walls.
- Removal of more than a certain percentage of the building's exterior.
- Demolition involving hazardous materials.
Converting Non-Living Spaces
Altering or converting non-living spaces such as garages, attics, or unfinished basements into habitable living areas requires specific permits in Hillsborough County. These conversions involve significant changes to the building's structure, electrical, plumbing, and mechanical systems, and must meet current building codes for occupancy.
- Definition of Habitable Space: Generally includes areas designed for living, sleeping, eating, or cooking, requiring adequate light, ventilation, egress, and insulation.
- Permit Triggers: Any work that changes the use of a space from non-habitable to habitable, including adding electrical outlets, plumbing, insulation, or finishing walls and ceilings.
- Code Compliance: These conversions must meet all applicable building, electrical, plumbing, and fire safety codes, including requirements for emergency egress from bedrooms.

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.
