Multifamily buildings built after 2000 have the best fire safety records in Massachusetts and across the nation, according to a new study from  The Pew Charitable Trusts.

Massachusetts apartment buildings built before 2000 saw a fire death rate of 4.7 per million residents in 2023 and 2024. During the same time frame, the fire death rate for apartments built in the last 25 years was zero.

Nationally, the discrepancy was even greater. In 2023 the fire death rate in post-2000 buildings was 1.2 per million residents, compared to 7.7 for older buildings.

“Modern apartments are often the best, fastest and most affordable way to construct new housing and ease the growth in housing costs — and they are also by far the safest homes in the U.S. in terms of fire deaths,” Alex Horowitz, project director of Pew’s housing policy initiative, said at a media briefing. “This data can help policymakers remove unnecessary barriers to new apartment construction, help address the housing shortage and actually save lives over time by providing renters and homeowners with safer housing.”
