DPS Jul 1, 2026
A new Maryland state law (House Bill 149) takes effect October 1, 2026, requiring automatic fire sprinkler retrofits and other life-safety upgrades when a residential rental high-rise undergoes substantial renovation. A high-rise is defined as a building with an occupiable story floor more than 75 feet above the lowest level of fire department access. Substantial renovation is defined as permanent alterations costing at least 40 percent of the building's assessed value as determined by SDAT.
