Battery-operated smoke alarms installed in residential multi-family dwellings built before 1987 must be replaced with 10-year sealed battery smoke alarms under these conditions: if the smoke alarm is older than 10 years, needs to be replaced for any reason, does not include a date of manufacture or the dwelling’s owners cannot prove that they have a program in place to test and maintain smoke alarms and replace batteries. This requirement excludes one- and two-family homes and townhomes.
