Calling All Universal Designers!!!

The challenging space in my universe is the 5-story walk-up apartment building, where I live on the fifth floor. Obviously a more universally designed space would allow for an elevator, but given the space accomodations that is permitted for the stairs, there simply is no room for an elevator or other apparatus to help.

Perhaps I could move to the first floor of the building, or install a pulley system to raise me up to my bedroom window, but isn't there a better idea? Can I utilize the fire escape on the outside of the building to make it more universally designed. Would an elevator be the only equitable, flexible and easy-to-use option?
