Final answer:
The ability of an owner-builder to pull a permit for plumbing varies and depends on state regulations, with some states allowing it for personal residences and others requiring licensed professional supervision.
Step-by-step explanation:
Whether an owner-builder can pull a permit for plumbing work depends on state regulations. In some states, owner-builders are allowed to perform plumbing work on their property without the supervision of a licensed plumber, as long as they are pulling the permit for a personal residence and not for commercial purposes. However, other states may require that all plumbing work be performed under the supervision of a licensed professional, or that the owner-builder passes certain tests or obtains specific credentials. Therefore, the correct answer to the question would be d. Depends on the state regulations. It's essential for an owner-builder to check the specific requirements of their state or local building authorities before proceeding with any plumbing work.
