Cash Side Work, an Owner-Occupied Neighbor, and a Friday Move-In
A journeyman plumber employed by a licensed plumbing contractor gets three requests in one week. First, a landlord who owns a duplex offers cash for a Saturday water heater replacement and a new exterior hose bibb, saying 'no permits, I'm the owner.' Second, a neighbor who owns and lives in a single-family house asks him to move a shower valve and add a hot-water recirculation line. Third, a property manager asks him to disconnect and cap a gas range in a rental unit and to 'just sign off' on a water heater a handyman installed last year, since the tenant moves in Friday. On the duplex water heater he finds the existing one vented with single-wall 26-gauge pipe running through a closet into a chimney, and no permit record for the original installation. Oregon adopts a statewide plumbing code enforced by local building departments or the state building agency, and permits and inspections apply to water heater replacements and gas piping.
1. Analyze the duplex request: licensing, permits, and the position the journeyman would put himself in by accepting it.

Licensing. A journeyman plumber's license authorizes performing plumbing work under the supervision of, or for, a licensed plumbing contractor. It does not authorize contracting. Anyone offering or contracting to do plumbing work for compensation must hold a plumbing contractor license, which involves the contractor registration and the qualifying plumber. Taking cash from a landlord to install a water heater and hose bibb is contracting, which puts the journeyman outside his license even though the work itself is within his skills.
The owner exemption does not reach a duplex rental. The narrow owner allowance for doing plumbing work on one's own property is framed around a single-family dwelling the owner occupies, and it is personal: no compensation, no employees, and permits and inspections still apply. A duplex with tenants is not that. So the landlord cannot lawfully self-perform unpermitted plumbing here either.
Permits and inspections. Water heater replacements and new hose bibbs require permits in Oregon jurisdictions, and the work needs inspection. Skipping the permit means the installation is undocumented, potential buyers and insurers will find it, and the licensed plumber is the one whose name gets attached when it is discovered.
Professional exposure. Unpermitted side work is the classic route to a complaint against the license and to personal liability without the contractor's insurance covering the job. The correct response is to decline the cash arrangement and offer to do it through his employer's contractor license, with a permit.
2. What is the difference between the duplex request and the neighbor's request, and how should the journeyman handle the neighbor?

The neighbor's facts are different in two ways. First, the property is a single-family dwelling that the owner both owns and occupies, which is where the owner self-perform allowance is aimed. Second, the request is to a neighbor as a favor rather than a paid contract; whether money changes hands is exactly the line that triggers contractor licensing requirements.
Practical path. Even for an owner-occupied house, plumbing work needs a permit and inspection. The cleanest arrangement is for the homeowner to obtain the owner's permit for his own residence and perform or take responsibility for the work, with the journeyman advising on how it should be done and what the inspector will look for. If the journeyman is going to do the physical work for compensation, he needs his employer's contractor license and a permit in the employer's name, plus whatever access and warranty arrangements the employer requires.
What to verify rather than assume. The parameters of the owner exemption and who may pull an owner's permit vary by jurisdiction and are set in statute. Before relying on the exemption, confirm the current requirement with the state building agency or the local building department, and confirm whether the jurisdiction will issue the permit to a homeowner for this scope.
Scope notes on the recirculation line. Moving a shower valve means opening a wall, altering the valve trim, and resetting the temperature-limiting requirements; adding a recirculation line means a return line sized correctly, an accessible pump or crossover, and insulation. These are not trivial 'favor' items if something leaks behind the tile.
3. Address the third request: capping the gas range, and the demand that the journeyman 'sign off' on the handyman's water heater installation.
Read the worked answer
Capping the gas range is real plumbing work. Disconnecting and capping gas piping in a rental unit requires a permit in Oregon jurisdictions, a proper listed cap or plug, leak testing, and an inspection. It is not a favor done after hours. The property manager's Friday deadline does not change the requirement, and moving a tenant into a unit with undocumented gas work creates a life-safety exposure for everyone involved.
Signing off on someone else's work: refuse. A licensed plumber cannot certify, approve, or 'sign off' an installation he did not perform and inspect. Only the authority having jurisdiction inspects and approves. If he signs, he has taken professional responsibility for a handyman's water heater, and if it fails, his license is the one on the line. What he can do is inspect it at the manager's request, in writing, as an observation, and convert the findings into a repair list and a permit application.
What the observed water heater needs. The vent connector is the headline defect: single-wall 26-gauge pipe requires substantial clearance to combustibles, commonly 6 inches, and it generally may not pass through a wall, ceiling, or partition. Running it through a closet means the fix is a listed double-wall vent connector with the required clearance and a proper thimble where it penetrates, or a rerouted vent, all verified against the appliance listing and the adopted code. Also check the T&P discharge termination and material, the drain pan and its discharge, seismic strapping if required locally, combustion air for a confined closet, the gas connector, and sediment trap.
How to handle the deadline. Put the refusal and the reasons in writing to the property manager, give the permit and repair path, and let the schedule problem be the manager's, not yours.
