Maryland’s New Smoke Alarm Law – Have You Complied?

Maryland’s New Smoke Alarm Law – Have You Complied?







The New Year marked the deadline for Maryland property owners to bring their smoke alarms up to date under the new law. Doing so will aid in passing a home inspection and avoiding penalties, not to mention ensuring that your home is equipped with safer, more dependable alarms. There is some confusion as to what the requirements are for smoke alarms as well as where they need to be placed, to which the chart below and this article will clarify.

First, gather the answers to these questions:

  1. What year was the property built?
  2. Is the current system hardwired, hardwired with a battery back-up, or only battery-operated?
  3. Where are the smoke alarms located?

Section 9-104 of the Public Safety Article requires that any battery-operated smoke alarm in residential property must now be a sealed, tamper resistant unit incorporating a silence/hush button and using long-life batteries, projected to have a ten (10) year lifespan.The silence/hush button allows an occupant to temporarily silence an alarm when they have set it off accidently and the occupant is aware of and can fix the issue (for example, burnt food on the stove).  Down the road, when these units are ten years past the date of manufacture (written on the unit), the law requires that they be replaced.The property owner is responsible for complying with the law; however, tenants are responsible for notifying their landlord of any problems with alarms, such as hearing the “end of life” sound during the ten-year cycle, to which the landlord is then on notice to repair.

If the property is currently hardwired, leave the system alone, and do not replace it with battery-operated units.  However, you still need to ensure that the property has smoke alarms in all areas required by the statute. If not, the long-life battery smoke alarms must be installed where necessary.
