Is it "of modern block" or has the building been there for years and had a upgrade.....usually the elevator is the LAST thing to be modernised ... who has been doing the maintenance up to now you should be able to get any and ALL info on service/breakdowns from them for free...if there has been noone then the previous manager/owners have been negligent in their safety to the tenants...
there are so many different rules and regulations in regard to installation/service etc that we need to know where you are from!!
