State guidance for Maryland
For plumbing in Maryland, prepare access to the affected fixture, shutoffs, mechanical area, drain, or buried line. Confirm the inspected scope, credentials, permits, inspections, exclusions, and restoration responsibility before authorizing work.
Credential verification
Plumbing in Maryland is regulated by the Maryland State Board of Plumbing within the Division of Occupational and Professional Licensing at the Maryland Department of Labor. For most plumbing work, hire a licensed plumber and verify the license through the Department of Labor before work begins.
State plumbing licenses are required throughout Maryland except in Baltimore County and the areas served by the Washington Suburban Sanitary Commission (WSSC) — Montgomery and Prince George's counties — which issue their own licenses and have their own plumbing code. The Board issues Master, Journey, and Apprentice plumber/gas fitter licenses, so it is fair to ask which credential a plumber holds and where it applies.
Permits and inspections
Permit and inspection requirements are set and enforced locally, so they vary by city and county. Your local building or permits department issues plumbing permits and inspects work before it is concealed, and homeowner-permit rules and fees differ from one jurisdiction to the next — Baltimore County and the WSSC counties also operate under their own plumbing codes. Always check with your local building or permits office first.

Plumbing in Maryland: FAQs
How do I prepare for plumbing in Maryland?
Document whether the symptom is isolated, shared by several fixtures, or affecting the whole property and prepare access to the affected fixture, shutoffs, mechanical area, drain, or buried line. Ask the professional to confirm the inspected scope, credential, permit responsibility, and exclusions in writing.
Does Maryland guidance diagnose my plumbing problem?
No. State information helps with credential, permit, and planning questions. The cause, responsibility, and repair or project scope still need to be confirmed for the specific property.
What does a plumber actually handle?
Most plumbing professionals handle leaks, clogged and slow drains, sewer lines, water heaters, pipes, toilets, faucets, sinks, garbage disposals, and sump pumps. If you are unsure who to call, describe the symptom and Plumbing Advisors can help point you to the right service.
How do I know if my plumbing issue is urgent?
Active leaking water, sewage backups, a burst pipe, or no water at all are usually urgent. Slow drains, minor drips, and a running toilet are important but typically not emergencies. When in doubt, call and describe what you are seeing.
Should I shut off my water before calling?
If water is actively leaking and the shutoff is safe and accessible, turning it off can prevent damage. You can shut off an individual fixture valve or the main water valve for the home. Avoid using the affected fixture until it is inspected.
Does Plumbing Advisors do the repair?
Plumbing Advisors is a connection and guidance service. We help you understand the problem and connect you with plumbing professionals that service your area. The professional you are connected with performs the work.
