The Maryland State Fire Prevention Code is a statewide set of rules covering smoke and carbon monoxide alarms, exits, fire suppression, hazardous materials, and fireworks, enforced by the Office of the State Fire Marshal. Knowingly violating it is a misdemeanor punishable by up to 10 days in jail, a fine of up to $1,000, or both, per offense.1Maryland General Assembly. Maryland Code Public Safety 6-601 – Violation of Title or Regulation The rules that matter most to you depend on whether you are a homeowner, a tenant, a landlord, or a business operator.
Smoke and Carbon Monoxide Alarms in Homes and Rentals
Automatic smoke alarms are required in every sleeping area of every residential occupancy in Maryland, including single-family homes, apartments, hotels, dormitories, and rooming houses. Public Safety Article 9-102 ties those requirements to the NFPA 101 Life Safety Code and requires that alarms be installed according to NFPA 72 spacing and placement standards.2Maryland General Assembly. Maryland Code Public Safety 9-102
If your home was built before January 1, 1989, and still uses battery-only alarms, the law required them to be replaced with sealed 10-year lithium battery units, with at least one alarm on every level. The final deadline for that upgrade was January 1, 2018.3Maryland Department of Labor. New Smoke Alarm Law Explanation – Office of the Maryland State Fire Marshal Homes built on or after January 1, 1989, that need two or more alarms must have those alarms interconnected, so that when one sounds, they all sound.4Maryland General Assembly. Maryland Code Public Safety 9-104 – Specific Requirements A separate provision effective July 31, 2025, requires smoke detectors in each interior public corridor of residential rental high-rise buildings, defined as buildings seven or more stories tall or over 75 feet in height.2Maryland General Assembly. Maryland Code Public Safety 9-102
Landlords are responsible for installing alarms and for repairing or replacing them after receiving written notice from a tenant. Tenants cannot remove or disable them.
Carbon monoxide alarms are governed by Public Safety Article, Title 12, Subtitle 11. A qualifying alarm senses CO, sounds an audible warning, and carries a listing from a testing laboratory approved by the Office of the State Fire Marshal. In hotels, rooming houses, and rental units, CO alarms may be hardwired with battery backup, sealed 10-year battery units, or tied to an on-site monitoring control unit.5Justia. Maryland Code Public Safety Title 12 Subtitle 11 – Carbon Monoxide Alarms A combination smoke and CO alarm is allowed if it meets both sets of standards.6Maryland General Assembly. Maryland Code Public Safety 12-1103 Homes with fuel-burning appliances or attached garages are the main targets of the CO rules.
What Commercial Buildings Have to Do
Commercial properties must comply with the Maryland Building Performance Standards, which adopt the International Building Code, the International Residential Code, and the International Energy Conservation Code with state modifications. Every jurisdiction in Maryland uses the same edition of these codes.7Maryland Department of Labor. Maryland Building Codes Administration
The building code sets fire-resistant construction standards, exit requirements, and occupancy limits. Commercial buildings must maintain clearly marked, unobstructed exit routes. Hotels, theaters, and other high-occupancy buildings need illuminated exit signs with backup power. Occupancy load calculations follow NFPA standards, which assign a specific square footage per person based on how the space is used; ground-floor retail generally allows one person per 30 square feet of sales area, while upper floors allow fewer.
Fire-rated doors and fire-resistant materials are required in many commercial and multi-family buildings to slow the spread of flame and smoke. Apartment buildings with multiple stories must maintain fire-resistant corridors and self-closing fire doors. High-rise stairwells must be enclosed with fire-rated materials. Fire escapes and emergency exits have to stay accessible at all times.
Fire Protection Systems and Inspections
Maryland has adopted NFPA 13 (2019 edition) for automatic fire sprinkler systems, which governs design, installation, and maintenance in commercial and high-rise buildings.8UpCodes. Maryland Fire Sprinkler Code 2019 Nursing homes, schools, and certain other commercial properties also require fire suppression systems.
Inspection and maintenance are legally required under COMAR 29.06.01. Fire alarm systems generally need annual inspections. Wet pipe sprinkler systems typically require quarterly checks, and dry pipe systems need additional maintenance because of freezing risk. Property owners must keep inspection records that local fire officials can request. Fire department connections must be clearly marked and accessible, standpipes require periodic inspection, and fire pumps in high-rises must be tested regularly.
Fireworks Rules and Permits
Under Public Safety Article 10-110, discharging or possessing fireworks with intent to discharge them is illegal without a permit, and selling fireworks without a permit is also prohibited.9Maryland General Assembly. Maryland Code Public Safety 10-110 – Prohibited Acts Certain ground-based and handheld sparklers are treated separately and may be sold and used without a license, but the line between legal sparklers and illegal fireworks is narrower than many people assume, and some counties impose stricter rules than the state.
Public displays require a permit from the Office of the State Fire Marshal or local fire authorities. Applicants have to submit safety plans, storage arrangements, and emergency response procedures. Displays must be run by certified pyrotechnicians using fireworks from licensed distributors, and organizers must carry liability insurance scaled to the size of the event.
Penalties are set out in Public Safety Article 10-111. Illegal possession or discharge is a misdemeanor with a fine of up to $250 per offense. Selling without a permit is a misdemeanor with a fine of up to $1,000 per offense. In either case, the State Fire Marshal must seize the fireworks at the owner’s expense, and the materials are forfeited and destroyed.10Maryland General Assembly. Maryland Code Public Safety 10-111
Hazardous Materials
Businesses that keep flammable liquids, compressed gases, or other dangerous substances on site must meet containment and labeling rules under COMAR 26.13. Storage units have to be fire-resistant with secondary containment, and facilities handling large quantities of chemicals must maintain current Safety Data Sheets and provide employee training.
Transportation rules incorporate federal law by reference. COMAR 11.07.01 adopts U.S. Department of Transportation regulations at 49 CFR 171 through 177 and 397, along with applicable Nuclear Regulatory Commission rules.11Library of Maryland Regulations. COMAR 11.07.01 – Transportation of Hazardous Materials Under Maryland Transportation Article 22-409, the Motor Vehicle Administrator and the Secretary of the Environment jointly adopt regulations covering vehicle placarding, approved routes, and driver certification.12Maryland General Assembly. Maryland Code Transportation 22-409 Drivers hauling hazardous materials must hold a Hazardous Materials Endorsement on their commercial driver’s license, which requires background checks and specialized training.
Workplace Fire Safety for Employers
Federal OSHA rules add another layer for Maryland employers. Under 29 CFR 1910.38, employers must maintain a written emergency action plan covering evacuation procedures, exit route assignments, methods for accounting for employees after an evacuation, and contact persons who can answer questions about the plan. If alarm systems are used, employees have to understand what each signal means.
Where portable fire extinguishers are provided for employee use, employers must train workers on the general principles of extinguisher operation and the hazards of early-stage firefighting. Training is required at hire and at least annually after that.13Occupational Safety and Health Administration. 1910.157 – Portable Fire Extinguishers Employers who use standpipe or hose stations connected to a sprinkler system in place of portable extinguishers must still train employees annually on that equipment. OSHA’s Hazard Communication Standard also requires Safety Data Sheets rather than the older Material Safety Data Sheets; the 16-section SDS format became mandatory for all shipments of hazardous chemicals after June 1, 2015.14Occupational Safety and Health Administration. Clarification on Effective Date of SDSs Replacing MSDSs
Inspections and Notices of Violation
Fire officials conduct routine inspections at a frequency that depends on property type and risk. Hotels, schools, and healthcare facilities typically face annual inspections; industrial sites handling flammable materials are reviewed more often. Inspectors check alarms, exits, suppression systems, and how combustible materials are stored.
When something is wrong, a fire marshal issues a Notice of Violation describing the problem, the required fix, and a deadline. Serious violations can trigger stop-work orders, license revocations, or temporary closures. Re-inspections follow to confirm the fix. Abatement orders directed at an occupant or owner must be served within five days of issuance, either by hand-delivery or, if the person cannot be found, by posting the order on the premises and mailing a copy by certified mail.15Maryland General Assembly. Maryland Code Public Safety 6-319
Penalties for Code Violations
Knowingly violating the State Fire Prevention Code or any regulation adopted by the State Fire Prevention Commission is a misdemeanor. A conviction under Public Safety Article 6-601 can result in up to 10 days of jail, a fine of up to $1,000, or both.1Maryland General Assembly. Maryland Code Public Safety 6-601 – Violation of Title or Regulation Penalties apply per offense, so multiple problems found in one inspection can compound.
When violations contribute to injury or property damage, additional criminal charges are possible, including felony charges if a violation led to a death or major structural damage. Civil exposure is a separate concern: a landlord who fails to maintain working smoke alarms or blocks emergency exits becomes a straightforward target in a personal injury or wrongful death lawsuit, and documented code violations create a record plaintiffs’ attorneys use.
How to Appeal a Citation
If you receive a citation or enforcement order from the State Fire Marshal and disagree with it, you can appeal to the State Fire Prevention Commission. The appeal has to be filed in writing within 20 days of receiving the order, and the petition must explain your reasons.16Justia. Maryland Code of Regulations 29.06.02.01 – Hearings – Contested Cases Before the State Fire Prevention Commission Missing that 20-day window usually means the original order stands.
At the hearing you can present evidence, call witnesses, and submit documents disputing the violation. If the Commission denies the appeal, you can seek further review through the Maryland Office of Administrative Hearings, where an administrative law judge weighs both sides. Judicial review in state court remains available after administrative remedies are exhausted. A successful appeal can produce a modified compliance order, reduced penalties, or dismissal of the citation.
