Apartment dwellers are likely to save on maintenance costs from next year after the government decided yesterday that elevators should be serviced based on how often they are used rather than once a month. Under the current law, apartment buildings must have their lifts maintained by technicians every month, regardless of how often they are used. But a joint ministerial decision yesterday means that this system will be scrapped. Following the decision, apartment blocks will need to have their elevators serviced between a minimum of five and nine times a year, depending on how many floors they have. The cost of maintaining lifts comprises a substantial part of service charges for people living in apartments, so residents should expect some savings. Lifts in public buildings will need to be serviced between 20 and 24 times a year.
