Monroe Township (Gloucester County), NJ Building Safety: Plumbing Permits (2026)

Plumbing work in Monroe Township answers to the Plumbing Subcode Official, a member of the Monroe Township Construction Code Enforcing Agency established by § 104-17 A. The fee schedule sits in § 104-18 C(1)(b), 'Plumbing fixtures and equipment,' and the same section sets a $75 minimum for a basic construction permit covering any or all of building, plumbing, electrical or fire protection work.

The standard charge is $15 per fixture, piece of equipment or appliance connected to the plumbing system, and for each appliance connected to gas piping or an oil piping system. Special devices cost $91 each. The printed list is grease traps, oil separators, water-cooled air-conditioning units, water connections, sewer connections, refrigeration units, utility service connections, backflow preventers, steam boilers, hot-water boilers (excluding those for domestic water heating), gas piping, gas service entrances, active solar systems, sewer pumps, interceptors and LP gas cylinder, sump pump and pressure booster pump. An LP fuel pipe other than heaters and an LPG tank install are also $91.

Other flat fees: $40 for a lawn sprinkler and $75 for a swimming pool heater, including the gas piping. Mechanical inspections performed by a plumbing inspector in R-3, R-4 or R-5 are $75 for the first device and $15 for each additional device.

Backflow preventers carry recurring costs. The annual reinspection of backflow preventer devices designed to be field tested, which isolate cross-connections between water supply and contaminants, is $75. A visual inspection by the Plumbing Subcode Official to confirm a device is on site before annual certification is also $75.

Permit timing follows § 104-21: the agency must grant or deny a permit application within 20 business days, and a permit expires if no work starts within one year or work stops for six months. Section 104-17 E requires 24 hours' notice before work begins.
