Building without a permit in Maryland

By Mario Bailey Last checked · 4 official sources

Quick answer

In Maryland, penalties for building without a permit are set by each county and municipality, not by state building law. The Maryland Building Performance Standards adopt the IBC statewide, but the subtitle contains no fine, misdemeanor, or stop-work provision for unpermitted work.

What Maryland law says

In Maryland, penalties for building without a permit are set by each county and municipality, not by state building law. The Maryland Building Performance Standards adopt the IBC statewide, but the subtitle contains no fine, misdemeanor, or stop-work provision for unpermitted work. Instead, state law directs that each local jurisdiction shall implement and enforce the Standards and any local amendments, including issuance of building permits and inspections, and local amendments prevail over the state Standards. Fines, stop-work orders, and civil or criminal penalties for unpermitted work therefore come from your county or city code.

Cited from Md. Code, Public Safety 12-503, 12-504, 12-505: official text. Localities enforce these rules and may add their own fees and procedures on top.

Can you get a permit after the work is done?

Maryland state law does not spell out a single statewide after-the-fact permit process; the path runs through your local permit office, which decides how already-built work gets reviewed, opened up for inspection, or corrected. Start with your locality's office below.

The typical path, whatever your locality calls it: stop any ongoing work, contact the permit office before they contact you, apply for the permit describing what was actually built, and expect the office to require opening up or inspecting concealed work. Voluntarily coming forward generally goes better than waiting for a complaint or a sale to surface it.

What Maryland permit offices charge when work starts first

The statute above sets the ceiling; the bill comes from the local office. One Maryland jurisdiction we cover publishes a specific surcharge for work started before the permit, quoted here from the fee schedule or permit page we verified, each linked to the page that carries the citation.

Jurisdictions not listed either publish no surcharge clause or publish one we could not quote from an official schedule; their permit pages state what we could verify.

Who can pull the permit

It depends on the trade and the county. Plumbing: state law exempts an individual who personally provides plumbing services in their own residence, but homeowners may not make final connections between the residence and public or private water supply or disposal systems, and Baltimore County plus the WSSC-area counties are largely carved out of the state plumbing title. Electrical: the Maryland Electricians Act prohibits providing electrical services for compensation without a license; it has no express homeowner exemption, so uncompensated work on one's own home falls outside the licensing prohibition, but each county decides whether it will issue an electrical permit to an unlicensed homeowner. Building permits are issued by local jurisdictions, which set their own owner-applicant rules.

Was a permit needed in the first place?

Not every project needs one. Across the 4 Maryland jurisdictions we have verified, 3 answered rules need no permit at all and 24 turn on a size or scope condition the jurisdiction publishes. If the work falls under one of those, the question changes from penalties to paperwork.
