New Hampshire, Coos County Remodeler Permit Regulations and County Ordinances for Unincorporated Areas
Coos County, New Hampshire Remodeling and Renovation Permit Requirements
Coos County, New Hampshire, has specific building and renovation permit requirements, particularly for properties located in unincorporated areas. It's crucial to understand that Coos County's Building & Safety Division (or its equivalent, the Coos County Planning Board for unincorporated areas) is the Authority Having Jurisdiction (AHJ) for these unincorporated regions. If your property is within an incorporated city, that city's building department will handle permit applications.
1. Authority Having Jurisdiction (AHJ)
For properties in unincorporated areas of Coos County, the Coos County Planning Board acts as the AHJ. They administer zoning, site plan review, and subdivision regulations. Their office is located at 34 County Farm Road, West Stewartstown, NH 03597, with a mailing address of PO Box 310, West Stewartstown, NH 03597. They can be reached by phone at 603-237-1920 or 603-237-1905.
2. Rules for Properties in Unincorporated Areas
In Coos County's unincorporated areas, any erection, construction, reconstruction, alteration of a structure, or change of use requires a county zoning permit. Before applying for a zoning permit, it's essential to review the Coos County Zoning Ordinance for Unincorporated Places to determine the applicable zoning district and any specific requirements.
3. Specific Permit Triggers for Demolition Work During a Remodel
Demolition work during a remodel may trigger the need for a demolition permit. Generally, permits are required for the demolition of primary structures, accessory structures with utility or mechanical systems, or additions/renovations that involve a substantial amount of demolition. Minor demolition of sheds or small garages without utilities or basements may be exempt. Interior demolition for renovation purposes also typically requires a permit.
Before a demolition permit is issued, you may need to provide a completed building permit application (checking "Demolition" as the type of work), a copy of the state-required Asbestos Report, and proof that utilities have been disconnected.
4. Permit Requirements for Altering or Converting Non-Living Spaces
Converting non-living spaces like garages, attics, or unfinished basements into habitable living areas generally requires a building permit in New Hampshire. This is because such conversions involve significant alterations and the creation of new living space, which must comply with current building codes and energy code requirements.
- Garages: Converting a garage into living space will require a building permit. This includes any associated plumbing, electrical, or mechanical work. Alternative off-street parking may be required if garage parking is eliminated. Building plans detailing the proposed work, including floor plans, window/door openings, and locations of safety features like smoke alarms, are typically required.
- Attics: To convert an attic into habitable space, you will likely need a permit. This typically involves ensuring adequate ceiling height (at least 7 feet for half the space), sufficient floor space (at least 70 sq. ft.), and providing code-compliant stair access and a secondary means of egress (like an egress window). Pull-down ladders are generally not sufficient for attic access in converted living spaces.
- Unfinished Basements: Finishing a basement into habitable space also requires a permit. Key requirements include ensuring proper egress (an emergency escape and rescue opening), adequate heating (capable of maintaining 68°F), insulation, and ventilation. Smoke and carbon monoxide detectors are mandatory. If converting to habitable space, provisions for combustion air for fuel-burning appliances must be made. Minimum ceiling heights are typically 7 feet for habitable spaces.
