Normalization makes buildings of different sizes easier to compare. A 20,000-square-foot property with 80 spaces and a 100,000-square-foot property with 400 spaces both have a ratio of 4.00 spaces per 1,000 square feet.\u003c\/p\u003e\n          \u003cp\u003eThe calculator also compares the current ratio with an optional target. That target can represent an internal design objective, a lease benchmark, a lender assumption, a market comparison, or a preliminary reading of a local parking standard.
