Permit and Supervision Dispute on a Three-Unit Apartment in New Hampshire
A New Hampshire licensed master plumber is asked by a general contractor to rough-in plumbing for a new three-unit apartment building in a town that has its own plumbing inspector. The contractor wants to start before the permit is issued because the framing crew is ahead of schedule. The contractor also wants the plumber’s unlicensed helper to install the water heater vents and gas piping while the plumber is on another job. The town inspector has not yet approved the plans, and the building department has a local amendment requiring backflow preventers on each unit’s water service. The plumber is told that the state license is enough and that local permits are only for the general contractor. The project is 10 days from a scheduled inspection.
1. What permit and licensing requirements apply before the plumbing and gas work can start?
Read the worked answer
The work cannot legally start before the required plumbing permit is issued. A state plumbing license authorizes the licensee to perform plumbing work, but it does not replace the local permit and inspection process. The local plumbing inspector has authority to require plans, permit applications, and inspections before work is concealed. The unlicensed helper may assist only under the direct supervision of the licensed plumber; the helper cannot independently install water heater vents, gas piping, or any other plumbing work for compensation. Gas piping may also require a separate gas-fitting qualification or license depending on the scope and local requirements, so the plumber must confirm that the helper is qualified and supervised. The plumber should refuse to start without a permit and should not allow the helper to work alone on regulated plumbing or gas systems.
2. How should the local amendment requiring backflow preventers on each unit be handled?
Read the worked answer
The local amendment must be followed. State codes generally set minimum requirements, and local amendments may be more stringent. If the town requires a backflow preventer on each unit’s water service, the plans and installation must include them even if the state code does not require them in every case. The plumber should obtain the amendment in writing, incorporate it into the plan review, and verify the type, size, and test requirements for each device. The devices must be accessible for testing and maintenance, and the installer must coordinate with the water utility and local inspector. The plumber should not treat the state license as a waiver of local requirements; the local inspector can reject the work if the amendment is not met.
3. What are the likely consequences if the contractor proceeds without the permit and with unsupervised helper work?
Read the worked answer
Proceeding without a permit can result in a stop-work order, required removal or exposure of concealed work, re-inspection fees, fines, and delays. Unsupervised plumbing or gas work by an unlicensed helper can expose the plumber and contractor to disciplinary action by the state licensing board, civil liability, and potential criminal penalties if the work is performed without required authorization. The plumber’s license is the professional responsibility; allowing unlicensed work under the plumber’s permit can be treated as a violation even if the plumber was not on site. The proper response is to stop, obtain the permit and plan approval, assign only qualified and supervised personnel, document the correction, and schedule the inspection with the local authority. The plumber should put the refusal and the reasons in writing to the contractor.
