Other things that can add cost fast are having too many elevators. I've been in 4 story buildings with 4 separate elevator shafts before that didn't have nearly the population or staff to ever get more than two moving at once. That just means higher rent to make a return on those 4 shafts mandated by some ordinance, which probably hurts you especially if you can't work and are living cheaply on disability. A lot of ordinances have been written with no understanding of how it would look in practice or the costs to implement them in the market and what that will mean for people who have to rent these units.
