Comprehensive Guide to Maryland State Laws and Codes for Smoke Alarms, Carbon Monoxide Alarms, and Natural Gas Alarms
In Maryland, homeowners and landlords must comply with specific regulations regarding smoke alarms, carbon monoxide (CO) alarms, and natural gas alarms. This guide provides an in-depth overview of Maryland’s state laws and codes, ensuring that residents are informed and compliant with safety standards.
1. Smoke Alarms
Maryland Code: Maryland Smoke Alarm Law (Public Safety Article 9-101 through 9-109)
Installation Requirements:
- New Construction: Smoke alarms are required in every bedroom, outside each sleeping area, and on every level of the home, including basements. Maryland’s regulations align with the International Residential Code (IRC).
- Existing Homes: As of January 1, 2018, Maryland law mandates that all battery-operated smoke alarms must be upgraded to 10-year sealed battery units. Hardwired smoke alarms in existing homes must be interconnected and have a battery backup.
Power Source:
- Smoke alarms should be either hardwired with a battery backup or powered by a sealed, non-removable battery with a minimum lifespan of 10 years.
Maintenance:
- Test smoke alarms monthly and replace the entire unit every 10 years. For units with replaceable batteries, replace the batteries annually unless the unit has a sealed battery.
Key Points:
- Interconnect smoke alarms so that if one detects smoke, all alarms will sound.
- Immediately evacuate the home and contact emergency services if a smoke alarm activates.
2. Carbon Monoxide Alarms
Maryland Code: Maryland Carbon Monoxide Alarms Law (Public Safety Article 12-1101 through 12-1105)
Installation Requirements:
- New Construction and Existing Homes: CO alarms are required outside each sleeping area and on every level of the home, particularly in homes with fuel-burning appliances such as gas stoves, heaters, or fireplaces. Maryland law mandates these installations to prevent CO poisoning.
Power Source:
- CO alarms must be hardwired with a battery backup or powered by a long-life, non-removable battery. Combination smoke and CO alarms are also permitted.
Maintenance:
- Test CO alarms regularly, replace batteries as needed, and replace the entire unit every 5 to 7 years as per the manufacturer’s guidelines.
Key Points:
- Install CO alarms according to the manufacturer’s instructions and test them regularly.
- If you suspect CO poisoning, characterized by symptoms such as headache, dizziness, and nausea, seek fresh air immediately and call emergency services.
3. Natural Gas Alarms
Maryland Code: Local Building Codes and Utility Regulations
Installation Requirements:
- New and Existing Homes: While Maryland does not have a statewide mandate for natural gas alarms, local jurisdictions may have specific requirements. It is recommended to install natural gas alarms near potential sources of gas leaks, such as gas appliances or utility rooms.
Power Source:
- Natural gas alarms can be hardwired into the home’s electrical system or powered by a long-life battery.
Maintenance:
- Regularly test natural gas alarms and replace batteries according to the manufacturer’s recommendations. The entire unit should be replaced based on the manufacturer’s timeline.
Key Points:
- Natural gas alarms are vital for detecting leaks that could result in fires or explosions. Ensure compliance with local codes and recommendations for installation.
- If a gas leak is suspected, evacuate the home immediately, avoid using electrical switches or open flames, and contact your gas utility provider or emergency services.

Baltimore:
- Installation Requirements: In Baltimore, smoke alarms must be installed in every bedroom, outside each sleeping area, and on every level of the home, including basements. CO alarms are required outside each sleeping area and on every level of the home. The city may also provide additional guidelines for natural gas alarms.
- Power Source: Both smoke and CO alarms must be hardwired with a battery backup or powered by a sealed battery with a lifespan of at least 10 years.
