Gaithersburg, Maryland Plumbing Local Permit Ordinances and Codes
Gaithersburg Plumbing Permit Ordinances
In Gaithersburg, Maryland, plumbing permits are primarily handled by the Washington Suburban Sanitary Commission (WSSC Water), while the City of Gaithersburg's Permit Center manages other construction-related permits. It's important to note that Gaithersburg operates independently from Montgomery County regarding permitting and code enforcement, meaning city-specific rules apply.
Authority Having Jurisdiction (AHJ)
For plumbing permits specifically, the WSSC Permitting Portal is where applications must be submitted. The City of Gaithersburg's Permit Center is responsible for issuing building, electrical, mechanical, and fire system permits.
Local Zoning and Fee Nuances
- Plumbing Permit Fees: Estimated fees for plumbing work in Gaithersburg range from $50 to $200, depending on the project's scope and valuation. For instance, adding a fixture typically costs between $50 and $200, while rerouting plumbing can range from $100 to $400. A specific fee schedule from 2017 indicates a base fee of $12.00 for the first fixture, with additional charges for subsequent fixtures and specific installations like water heaters or gas ranges.
- WSSC Jurisdiction: While Gaithersburg has its own permitting department for general construction, plumbing permits fall under WSSC's purview, which covers both Montgomery and Prince George's Counties. This means that licensed plumbers must be WSSC-licensed, and homeowners can only perform plumbing work if it aligns with specific WSSC regulations.
- Permit Requirements: Permits are generally required for new plumbing installations, alterations, and repairs. This includes adding fixtures, water heater work, and rerouting plumbing. Replacing a fixture is often exempt, but specific details of the project determine the need for a permit.

This includes a Maryland Home Improvement Contractor (MHIC) license for building permits, a Master Electrician License for electrical work, a Master HVAC Contractor License for mechanical permits, and a Master Plumber License for plumbing permits.

Montgomery County Plumbing Permit Requirements
In Montgomery County, Maryland, plumbing permits are not issued by the county itself but by the Washington Suburban Sanitary Commission (WSSC Water). WSSC Water handles water and sewer services for both Montgomery and Prince George's Counties. Most significant plumbing work requires a WSSC permit and inspection, and must be performed by a WSSC-licensed plumber. This includes projects such as replacing a water heater, installing new water lines, or converting a system from gas to electric. Gas appliance replacements or installations require a specific WSSC gas permit and must be done by a WSSC-licensed gas fitter. Minor repairs, such as fixing a leaky pipe or replacing a small section of piping (less than 10% of the total), may be exempt, but it's best to confirm with WSSC Water.
The Montgomery County Department of Permitting Services (DPS) is the county-level jurisdiction for building and safety. While DPS handles building permits, electrical permits, and mechanical permits, plumbing permits fall under WSSC Water's purview. For properties in unincorporated areas, such as Bethesda, the county's DPS still administers building permits. However, plumbing permits remain under WSSC Water's jurisdiction, regardless of whether the property is in an incorporated or unincorporated area.
- County-Level Jurisdiction: Montgomery County's Department of Permitting Services (DPS) oversees building, electrical, and mechanical permits.

Maryland Plumbing Code and Legislation
The state-level plumbing standards in Maryland are primarily governed by the Maryland Board of Plumbing, which operates under the Maryland Department of Labor. The state adopts model codes published by the International Code Council (ICC) to establish minimum installation standards for plumbing systems, including potable water, drain-waste-vent (DWV) systems, and fuel gas piping.
While Maryland establishes statewide standards, it is important to note that certain jurisdictions, specifically Baltimore County and areas served by the Washington Suburban Sanitary Commission (WSSC), maintain their own independent licensing requirements and may enforce their own specific plumbing codes. Practitioners should always verify the specific code edition and any local amendments with the local authority having jurisdiction (AHJ) where the work is being performed.
