When is a Plumbing Permit Required on a Residential Project?
A Plumbing Permit is required to install, enlarge, alter, repair, remove, convert, or replace equipment, potable water supply and distribution piping, fixtures and traps, drainage and vent pipes, building drains and sewers including laterals, including their respective joints and connections, devices, receptors, and appurtenances or any other component of a plumbing system.
Some examples of typical residential plumbing projects that require a Plumbing Permit are: new house construction; fix-up/rehabilitation repair projects; plumbing work associated with remodeling, renovating or enlarging a house; resetting, relocating, or installing plumbing fixtures associated with remodeling or reconfiguring kitchens or bathrooms; installing bathrooms, bar sinks, or other plumbing associated with finishing basements; repairing or replacing the water distribution piping, building drain/waste piping, or vent system; replacing a water heater; installing or replacing a backflow device for a lawn irrigation system, etc.
With respect to repairs, a Plumbing Permit is required to repair the plumbing system in a building or structure that has been damaged from fire, flood, or severe wind; and as part of a fix-up/rehabilitation building project, to repair or replace plumbing fixtures and/or components of a plumbing system that have not been maintained in good condition due to lack of on-going maintenance or neglect.
Residential building projects within unincorporated county and contracting municipalities that include plumbing work are issued as an Integrated Building Permit (one permit for the entire job). Plumbing work must be done by a licensed Master Plumber or qualifying homeowner.
The following types of work are considered minor ordinary repairs or minor work for which a Plumbing Permit will not be required; provided such ordinary repairs are regularly performed as on-going continued maintenance for the purpose of maintaining the building's plumbing system in good condition:
- Minor repairs within the interior of any building. That includes leaks in drains, pipes, traps, and valves, opening waste or supply pipes, and traps or drains. (Note: Minor repairs shall not be construed to include any work involving connections to or replacement or rearrangement of soil pipes, supply pipes, waste pipes, vent pipes or inside rain leader pipes, or the replacing or setting of any fixture, or replacement or repairs to Backflow Prevention devices, pressure reducing or regulating valves. A permit is required for this kind of repair work.)
- Replacing internal components within a water closet tank such as a defective flush valve, float, stopper/flapper, replacing internal components such as washers on a faucet or hose bib, replacing defective TPR valves on water heaters, and replacing treaded hose bibs
- Replacing a kitchen or bathroom faucet or garbage disposal in the same location, provided that no additional repair work is required beyond the fixture tubing connections or disposal waste connections
(Note: A Plumbing Permit is required to replace and/or reset fixtures such as kitchen sinks, water closets, bathroom sinks, tubs, or showers, or to replace/install dishwashers as part of simple kitchen and bathroom remodels, as well as to extend/modify the water supply piping and/or trap arm and waste/drain piping to accommodate reconfigured kitchen cabinet or bathroom layouts on more complex kitchen or bathroom remodels, etc.)
- Installing a lawn irrigation system beyond the required backflow device
(Note: A plumbing permit is required for the installation of the required backflow device.)
