Sullivan County Plumbing Permit Requirements
In Sullivan County, New Hampshire, building permits, including those for plumbing work, are typically issued at the local city or town level, rather than by a county-level building and safety division. This means that the specific requirements, application processes, fees, and inspection schedules will vary depending on the municipality where the property is located.
For properties in unincorporated areas, the New Hampshire State Building Code applies. However, not all communities in New Hampshire have local building code enforcement officials. In municipalities without local enforcement, the State Fire Marshal's Office is responsible for enforcing the code. Regardless of local enforcement, property owners and design professionals are still required to meet the New Hampshire State Building Code requirements.
New Hampshire has adopted statewide building codes, which include the International Plumbing Code (IPC). As of July 1, 2024, the state uses the 2021 International Residential Code (IRC) and the 2021 International Building Code (IBC) as base standards. All plumbing work must comply with these codes, including any state-specific amendments.
Homeowners in New Hampshire may be permitted to perform their own plumbing work on their primary, single-family residence, provided they occupy the home and it does not contain other dwelling units. However, they must still adhere to the plumbing codes and may need to schedule a pre-permit meeting. If a homeowner hires a licensed plumber, the plumber is responsible for obtaining the necessary permits.
Key aspects of plumbing permits generally include:
- Permit Application: A completed application form is required.
- Plumbing License: In many cases, permits are issued only to New Hampshire Licensed Master Plumbers.
- Plans/Drawings: A drawing, sketch, or formal plan set may be required, especially for new construction or significant alterations.
- Inspections: Plumbing work typically requires inspections, including rough-in and final inspections, before work is covered or completed. A 24-hour notice is usually required for inspections.
- Fees: Permit fees vary by municipality and are often based on the type and number of fixtures.
