Lifts are vital to have in any modern new building for accessibility it is expected and often a legal requirement, this may even cover apartment buildings. If you own a building though you will want to have elevators anyway to boost your credibility and rental incomes. It isn’t just people in wheelchairs that use lifts, people with other disabilities and illnesses may find them easier and people will often simply not want to take the stairs to get to their office or apartment especially if they are in a hurry. For a business staff being able to get to their floor by an elevator is preferable as it will be quicker for them and not tire them out making them more efficient.
Even in older buildings then you should if possible add lifts, it may boost your rental income and make it easier to rent premises but even if it is a building use for your own business or a business you work for there are benefits for your company. For clients visiting a business an old building can be impressive but without a lift it will just come across as being somewhere you are using because it is cheap.
