Who Pulls the Plumbing Permit in Baltimore County?

In Baltimore County the plumbing permit is pulled by a plumbing and gasfitting contractor licensed by the county, not by the homeowner and not by the general contractor. The permit is tied to that license holder, who answers for the inspections. Remodel Now remodels bathrooms and kitchens throughout Baltimore County.

The short answer, and the part people get wrong

In Baltimore County, the plumbing permit is applied for by a plumbing and gasfitting contractor who holds a Baltimore County license. The county states it in one line on its plumbing and gasfitting permit page: a permit is required for all plumbing and gasfitting work, and only a Baltimore County licensed plumbing or gasfitting contractor can apply for a plumbing or gasfitting permit.

There is no homeowner exception on that page and no general contractor exception. The exceptions the county does publish are narrow and have nothing to do with a bathroom or a kitchen: propane gasfitters working under a recognized certificate, pump installers, water conditioner installers and well drillers.

Most people assume the permit belongs to whoever is running the job. It does not. It belongs to a named individual who holds a county license, signed a licensing agreement with the county, carries insurance the county can verify, and will be the name sitting on the inspection record for that address long after the tile is grouted. Once you see the permit that way, several confusing parts of a remodeling contract start to make sense.

The permit is attached to a license, not to a property

Part 104.8.1 of the Plumbing and Gasfitting Code of Baltimore County, adopted by Council Bill 94-23 and effective July 1, 2024, makes it unlawful for any individual, partnership, firm or corporation to commence any installation, alteration, repair, replacement, conversion or addition to a plumbing or gas system without first obtaining a permit. Part 104.9.1 then answers who may ask for one. Applications shall be made in writing by the license holder, or their agent, proposing to do the work covered by the permit.

Read those two parts together and the logic is plain. The county is not permitting a project. It is permitting a person to do a described piece of work at a described address, and then holding that person to it. Part 105 of the same code requires individuals performing plumbing or gasfitting work within its scope to be licensed in accordance with Article 21, Title 15, Subtitle 2 of the Baltimore County Code.

This is also why the obvious homeowner question has an awkward answer. Under state law, Section 12-301 of the Business Occupations and Professions Article does not apply to an individual who personally provides plumbing services in their own residence, though the same section bars that individual from making the final connection between the residence and a public or private water supply or disposal system. State licensing and county permitting are two separate gates. Getting past one does not get you past the other, and in Baltimore County the permit application is the gate that stops a homeowner. If you plan to do your own work, call the Bureau of Plumbing and Gasfitting Inspections at 410-887-3620 and get the answer for your address before you buy a single fitting.

Your general contractor is usually not the applicant either

A remodeling company that sells you a bathroom is operating under a Maryland Home Improvement Commission license. A plumbing contractor who opens your drain line is operating under a Baltimore County plumbing license. They come from different bodies under different law, and one does not substitute for the other.

The county's addition, alteration and structural modification page puts both in the same paragraph. All electrical or plumbing work requires a permit and must be obtained by a licensed electrician and plumber. Separately, all residential alterations or additions by a private contractor require the Maryland Home Improvement License number of that contractor. The bathroom alteration permit page says the same thing from the other direction: an alteration permit is required for all commercial bathrooms, a permit is not required for residential bathrooms, but plumbing and electrical permits are always required, and the licensed plumber and electrician may apply for their respective permit before the work is initiated.

Here is how the two credentials divide up.

  • Issued by. MHIC license: the Maryland Home Improvement Commission. Baltimore County plumbing license: Baltimore County, administered through Permits, Approvals and Inspections with the county Plumbing and Gasfitting Board advising.
  • Covers. MHIC license: selling and performing home improvement work on a residence. Baltimore County plumbing license: performing plumbing and gasfitting work within the scope of the county plumbing code.
  • Allows a plumbing permit application. MHIC license: no. Baltimore County plumbing license: yes.
  • Appears on the contract. MHIC license: required by law, with the contractor's name and address. Baltimore County plumbing license: not required by law, so ask for it in writing.
  • Renewal cycle. MHIC license: set by the commission. Baltimore County plumbing license: April 30 of every odd numbered year.
  • Where to verify it. MHIC license: the state home improvement license search. Baltimore County plumbing license: the county for the permit itself, plus the state plumbing license search for the individual.

Maryland removed one source of confusion here in 2016, when it eliminated the home improvement subcontractor license category. A plumbing company doing home improvement work for an MHIC licensed contractor does not need its own MHIC license for that work. The county plumbing license is untouched by that change. It is still required, and it is still the only way the permit gets filed.

So the practical arrangement on most jobs is that your contract is with the remodeler, and the plumbing permit is in the name of a plumbing contractor you may never meet. Ask for that name and that license number in writing before demolition. Remodel Now remodels bathrooms and kitchens in Woodlawn, Towson, Parkville and the rest of Baltimore County, and homeowners comparing bathroom remodeling proposals around Towson should be able to get that information from any bidder without friction. If a bidder cannot tell you who is filing the plumbing permit, that is worth a second conversation. The number here is (301) 798-4696.

What a Baltimore County plumbing license actually involves

The county's plumbing licensing and certification page lists the tiers: master plumber gasfitter, master plumber, master gasfitter, the journeyman equivalents, plus onsite utility contractor, disposal system contractor and drain and sewer cleaner. The Plumbing and Gasfitting Board advises the director of Permits, Approvals and Inspections on how all of it is administered.

Two details on that page matter to a homeowner more than the rest.

The first is insurance. The county requires general liability and property damage coverage, and it requires the policy to be in the licensee's own name rather than the company name, with Baltimore County listed as an additional insured on the policy. That is an unusual structure. It means the coverage behind your permit follows the individual who pulled it, and the county can check the certificate itself rather than take a contractor's word for it.

The second is reciprocity. The Baltimore County Plumbing Board reciprocates only with the State of Maryland, the Washington Suburban Sanitary Commission, and Baltimore City for gas only. The traffic is just as narrow going the other way. The Maryland State Board of Plumbing issues a reciprocal master or journey license only to plumbers currently licensed in Baltimore County, WSSC or the District of Columbia, and it reciprocates with Delaware for the master plumber gasfitter license alone. A plumber holding a perfectly valid Maryland master license who has never reciprocated into Baltimore County cannot apply for your permit, and getting that license is not a same week errand. It involves a letter of good standing, a current license copy, backflow prevention certification for anyone licensed after October 1, 1993, an insurance certificate, a business letter, and a signed Plumbing License Agreement with the county.

County licenses expire April 30 of every odd numbered year, with a renewal window that opens sixty days before expiration. An expired license is a stopped job.

Which parts of a bathroom or kitchen job actually need the permit

Part 104.8.2 of the county plumbing code lists the work that escapes a permit, and the list is short. Stopping leaks in water, drain, vent or fuel gas piping, with the caveat that if the defect requires removal or replacement with new material it becomes new work and a permit is required. Clearing stoppages or obstructions to flow. Repairing leaks in valves or fixtures. Removing and reinstalling a water closet to reach a cleanout, provided the reinstallation does not require replacement or rearrangement of valves, pipes or fixtures. Repairing faucets and replacing water closet parts.

Essentially nothing in a real remodel fits. A new vanity on a new drain connection is replacement work. A tub to shower conversion moves a drain and swaps a valve body. A relocated toilet rearranges pipe. A kitchen sink moving to an island is new drain and new vent. The code also notes that an exception from obtaining a permit is not authorization to perform work that violates the code, so a repair that stays permit free still has to be done correctly.

The county's language is worth repeating because it closes the usual loophole. Pulling a toilet to snake a line is exempt. Pulling the same toilet and setting it eighteen inches to the left is not.

What the permit holder is actually signing up for

The permittee, meaning the license holder, carries obligations that outlast the invoice.

Part 104.11.1 puts the burden of checking and testing the work on the permittee, with all work subject to inspection by the authority having jurisdiction. Part 104.11.2 requires the permittee to notify the county when work is complete and ready, to coordinate scheduling, and to provide access and the means of testing. The sentence in that part that costs the most money is the last one: where the work has been concealed prior to inspection, it shall be made accessible as required until the necessary inspections are complete. New tile over an uninspected rough is not a fait accompli. It is a demolition order waiting to be written.

Part 104.12.1 forbids connecting any plumbing piping to a fixture, appliance or equipment before county approval. Part 104.6.4 lets the county issue a written stop work order. Part 104.10.4 covers the aftermath of skipping all of it: where work is performed on site without first obtaining a permit, the county investigates and the investigation fee is paid before a permit may be issued.

Reinspection exposure sits with the permittee too. The code lists six conditions that can trigger a reinspection fee, and only one of them is bad workmanship. The others are failure to provide access at the scheduled time, no approved plans on site where required, work not complete when the inspection was called, corrective work not finished by the rescheduled visit, and work that deviates from the approved plans and has to go back through review. Four of those six are scheduling and paperwork, which is why an organized plumbing contractor is worth more than a fast one.

The permit moves with the license holder, not with the house

This is the part that surprises people mid project, and it is the clearest proof that the permit is not yours.

Baltimore County publishes three separate forms for it. A license holder who wants out files a request to cancel, and must attach a copy of the signed notice of cancellation sent to the property owner, on business letterhead or from a company email. A property owner who wants to remove a plumber files a different form, and must attach a copy of the signed notice of cancellation sent to the licensee, confirming in writing that the owner has already notified them. Both forms ask for a description of the permitted work already completed and the permitted work still to be done.

The transfer form is stricter. Along with notice to the property owner, it requires a letter from the incoming license holder, on business letterhead, stating that they are taking responsibility for all new work to be completed under the new permit. Nobody inherits another plumber's rough-in by accident.

Think through what that means if a job stalls. You cannot simply hand the open permit to the next plumber and carry on. Somebody has to cancel or transfer it, the incoming licensee has to accept responsibility in writing, and the second plumber is entitled to look hard at work they did not do before signing anything. Price that risk into how you pay. A plumbing contractor who has been paid ahead of the inspection schedule has less reason to come back.

The county amendments that decide whether your layout passes

Baltimore County does not enforce the model plumbing code as printed, and the differences land squarely on small bathrooms.

Part 104.2.1 is the first surprise. The plumbing and fuel gas requirements of the International Residential Code in chapters 20, 24, 25, 26, 27, 28, 29, 30, 31, 32 and 33 shall not be used for residential plumbing and fuel gas systems in Baltimore County. The county's own plumbing code applies to houses instead. Anyone quoting an IRC plumbing chapter at you for a Baltimore County bathroom is reading the wrong book.

Wet venting is amended. Under the county's version of 912.1, fixtures in one bathroom group or two adjacent bathroom groups on the same floor level may be wet vented, and the fixtures that can be wet vented are lavatories, water closets, bathtubs, showers and tub showers. Then comes the restriction that kills a lot of clever layouts: water closets and urinals shall not be drained by wet vent piping, which is limited to draining waste, although they can be vented by wet vent piping. Two bathrooms back to back on the same floor can share a wet vent. Two bathrooms at opposite ends of a hallway cannot, because they are not adjacent. The model chapter the county starts from is IPC 2021 chapter 9, but the county bill sits on top of it and wins.

Air admittance valves are the other trap. The county deleted IPC sections 918.2 through 918.8 outright and wrote its own 918.1 in their place. An AAV may vent an individual fixture only if the authority having jurisdiction permits it, only where the fixture is an addition or modification to an existing plumbing system, only on a lavatory, sink or standpipe with a small drain connection, only where an existing condition prevents proper installation of vent piping, and only when installed vertically at least 4 inches above the top of the fixture trap arm with free air movement and access for replacement. A contractor who plans an island sink around a stock AAV without asking the county first is planning a failed inspection.

None of these are details a homeowner should have to referee. They are, however, exactly what you are buying when you pay for a county licensed plumbing contractor instead of a handyman with a van.

How to confirm the permit was actually pulled

Do not take a verbal yes. Three checks take about fifteen minutes between them.

Start with the county's permit search map. Accept the disclaimer, use the add data tool to load the permit layers, and note that plumbing, electrical, gas and building permits are separate layers. Add the ones you care about, then open the find tool and enter your address. Permits populate on the right, grouped by trade. A permit number works too, and will show whether the permit was issued and what work was completed. The county's records search page is the hub for all of it, and it also warns that most files are retained for three years and then destroyed, which is a good reason to save your own copies at the end of a job rather than assume the county will hold them.

Second, verify the people. Maryland's home improvement license search covers the remodeling company. The plumbing license search covers the individual plumber. Read the status line carefully on the plumbing side, because the state board publishes an insurance status and only insured master plumbers may contract to perform plumbing or gas services. An active license marked not insured to contract is not a green light. The same page notes that a master plumber must display the license number on each vehicle used on the job, which is a free check from your front window.

Third, watch the sequence. Permits before demolition, rough plumbing inspection before anything covers it, no fixture connections before approval. If the schedule a contractor hands you shows backer board going up before a rough inspection date, the schedule is wrong, not clever.

What a missing plumbing permit does when you sell

Baltimore County permit data is public and searchable by address, so a buyer's agent, a home inspector or an underwriter can see what was permitted on your house and what was not. A bathroom that is visibly newer than the rest of the house, with no plumbing permit on record, becomes a question that has to be answered during a contract.

Maryland's disclosure law then puts the seller on the spot. Under Section 10-702 of the Real Property Article, a vendor of single family residential property must deliver either a written residential property condition disclosure statement or a written disclaimer statement on the State Real Estate Commission's form. The disclosure form covers water and sewer systems, structural systems, and plumbing, electrical, heating and air conditioning systems, along with any other material defects within the seller's actual knowledge. The disclaimer route, the one that sells a house as is, still requires disclosing latent defects the seller actually knows about, defined in the statute as material defects a purchaser would not reasonably ascertain by a careful visual inspection and that would pose a direct threat to health or safety.

An unvented fixture drain behind finished tile fits that definition uncomfortably well. The usual outcome is not a courtroom. It is a credit at the table, a retrade after the inspection, or a lender who wants the work permitted before closing. Permitting after the fact runs through the investigation path in Part 104.10.4, and because concealed work has to be made accessible until the required inspections are complete, that often means opening a finished bathroom back up.

What to ask before the first pipe is cut

Five questions. None of them are about tile.

Who is applying for the plumbing permit, and what is their Baltimore County license number? You want a name, a number, and the ability to check both. A shrug is an answer.

Is that license current, and is it a Baltimore County license rather than a Maryland or WSSC license alone? Reciprocity exists, but it has to have already happened. Ask when the license was last renewed, given the April 30 odd year cycle.

Who schedules the rough inspection, and what happens if it fails? The permittee is responsible for coordinating inspections and providing access. You want to hear that the plumbing contractor handles the scheduling and absorbs a reinspection caused by their own work.

Will anything be covered before the rough passes? The correct answer is no, in plain language, with no qualifiers about keeping the schedule.

What is the plan if the plumbing contractor leaves mid job? A contractor who has read the county's cancellation and transfer forms will tell you that the permit has to be formally cancelled or transferred and that the incoming licensee has to accept responsibility in writing. A contractor who has not will tell you it never happens.

Your home improvement contract is where several of these answers belong in writing. Maryland requires the contract to be in writing and legible, to carry the contractor's name, address and MHIC license number, to describe the work and the materials, to give approximate start and substantial completion dates, and to be signed by both parties, with a signed copy in your hands before work starts. A contractor may not take more than a third of the contract price as a deposit and may not take any payment before the contract is signed. Nothing stops you from adding the plumbing contractor's name and county license number to that document before you sign it.

Frequently Asked Questions

Who pulls the plumbing permit in Baltimore County?

A plumbing and gasfitting contractor licensed by Baltimore County. The county's plumbing permit page states that a permit is required for all plumbing and gasfitting work and that only a Baltimore County licensed plumbing or gasfitting contractor can apply for one. Part 104.9.1 of the county's plumbing and gasfitting code says the application must be made in writing by the license holder or their agent. The published exceptions cover propane gasfitters, pump installers, water conditioner installers and well drillers, none of which apply to a bathroom or kitchen remodel.

Can my general contractor pull the plumbing permit?

Only if that contractor also holds a Baltimore County plumbing and gasfitting license, which is a separate credential from a Maryland Home Improvement Commission license. The MHIC license lets a company sell and perform home improvement work on a residence. The county plumbing license is what allows a permit application to be filed. On most remodels your contract is with the remodeler while the plumbing permit sits in the name of a plumbing contractor, so ask for that name and license number in writing before demolition starts.

Can I pull my own plumbing permit as the homeowner in Baltimore County?

The county's permit page lists no homeowner exception. State law is a separate question: Section 12-301 of the Business Occupations and Professions Article does not apply to an individual who personally provides plumbing services in their own residence, although that same section bars that individual from making the final connection to a public or private water supply or disposal system. State licensing and county permitting are two different gates. Call the Bureau of Plumbing and Gasfitting Inspections at 410-887-3620 about your specific address before starting.

Does a Maryland state plumbing license let someone pull a Baltimore County permit?

Not by itself. Baltimore County issues its own plumbing and gasfitting licenses and its Plumbing Board reciprocates only with the State of Maryland, the Washington Suburban Sanitary Commission, and Baltimore City for gas only. A plumber holding a valid Maryland master license still has to reciprocate into a Baltimore County license before applying for a county permit, and that process requires a letter of good standing, an insurance certificate, a backflow prevention certificate in many cases, and a signed Plumbing License Agreement with the county.

How do I check whether the plumbing permit on my house was actually pulled?

Use the county's permit search map. Accept the disclaimer, load the permit layers through the add data tool, then enter your address in the find tool. Plumbing, electrical, gas and building permits appear as separate layers, so load the trade you are checking. A permit number also works and will show whether the permit was issued and what work was completed. For formal copies, the county's records page explains the confirmation of records request, and it notes that most files are retained for three years before being destroyed.

What happens to the permit if my plumber walks off the job?

It has to be cancelled or transferred on paper. Baltimore County publishes separate forms for a license holder cancelling a permit, a property owner cancelling a permit, and a license holder transferring one. Each requires written notice to the other party and a description of the work already completed and still outstanding. A transfer additionally requires a letter from the incoming license holder, on business letterhead, stating that they are taking responsibility for all new work to be completed under the new permit.

Does a small bathroom update really need a plumbing permit?

Almost always, yes. Part 104.8.2 of the county plumbing code exempts only stopping leaks, clearing stoppages, repairing leaks in valves or fixtures, removing and reinstalling a water closet to reach a cleanout where no pipe is rearranged, and repairing faucets or replacing water closet parts. A new vanity on a new drain connection, a tub to shower conversion, a relocated toilet or a sink moved to an island are all new work. Tile and paint on their own do not trigger a plumbing permit.

What does a missing plumbing permit cost me at resale?

Usually a credit, a retrade after inspection, or a lender requiring the work to be permitted before closing. Baltimore County permit data is searchable by address, so the gap is visible. Section 10-702 of the Real Property Article requires a seller to deliver a condition disclosure or a disclaimer statement, and even the as is disclaimer route requires disclosing known latent defects that a careful visual inspection would not catch and that threaten health or safety. Permitting after the fact runs through the county's investigation process and often means opening finished work back up.
