Do I need a permit to replace a water heater in Little Rock?

Yes. Replacing a water heater typically requires a plumbing permit in Little Rock. The work must also meet the current 2018 Arkansas Plumbing Code requirements for installation, venting (if applicable), and safety devices. A licensed plumber can pull the permit and handle the inspection.

Do minor repairs need a permit?

Usually not. Simple repairs such as replacing a faucet cartridge, toilet flapper, or supply line generally do not require a permit. If the work involves changing the plumbing system itself (new pipes, relocating fixtures, or major drain work), a permit is normally required.
