Owners of building classes 2-9 (multi-storey, dwelling units, motels, guest house, offices, shops, warehouses, factories, hospitals, public buildings and schools) are required to maintain all essential safety measures that are installed in a building. If your building was either constructed or altered since July 1, 1994 then all essential safety measures will be listed on the Occupancy Permit with the requirements for the level and frequency of this maintenance.
For buildings that were constructed before July 1, 1994, any essential safety measure installed in the building will have to be maintained to ensure that it functions properly.
The Building Commission has produced an Essential Safety Measures Maintenance Manual that lays out all the requirements and responsibilities of property owners.
