What are USF and RSF?
This refers to Usable Square Feet vs. Rentable Square Feet. USF is the amount of the space that you can actually occupy. The RSF refers to the USF plus a portion of the common areas, such as hallways, that you are charged for. Rent is typically based on RSF, even though you are only occupying USF.
