Elevators are for many public buildings not an option but essential. With elevators you may need them legally in order that the building you own or manage is accessible to disabled persons or you may need them because they are expected by customers or tenants. Buildings of a certain age often don’t have lifts but even with three or four storeys or more or even just two storey’s elevators may be expected and you may have trouble letting space without them. This includes apartments where without a lift the top floor will fetch the least rent, with a lift assuming there is a good view top floor apartments will fetch the most rent. As for offices you may be unable to let out offices or have to let them out for a pittance if there is no lift. Large businesses need to have lifts for clients including disabled clients and need to have a policy where they will give disabled people a fair chance of getting a job, if they don’t have access then they won’t be able to do this. Shops as well in malls and mini malls with no lift access will be equally difficult to let for the same reasons and because some customers will be unwilling to visit a shop if they have to climb stairs.
