There may be several options for you. My grandfather is retired from a fire department that worked with tall buildings and has told me about several ways to climb a building with only a small amount of equipment. They don’t use many of these techniques anymore because of advances in trucks or for liability reasons but one or two guys that knew what they were doing could in an emergency access a 4 story building easily. Also plan for and or prepare some good anchor points ahead of time for where you are. Shock loading a rope will make you need a bigger anchor than you think. If you are tying off to something make it several things always double up so Murphy and his little silver hammer will strike somewhere else. Oh best book in my library for this is called “On Rope” by Allen Padgett and Bruce Smith.
