Our standard code is 2 stalls per 1,000 square feet but the ** in the code allows an increase beyond the maximum 25 percent of the maximum. I have a bank in a special zone where the code is written specifically for the development. It is a goofy formula used to calculate parking so I use the standard code. The difference in parking with the formula versus the standard code is about 6 percent. So with a development of over 1,000 stalls, not a noticeable difference. A bank at 3,800 square feet wants 40...40 stalls! 40 stalls would allow a general retail building of 10,000 square feet. Google Earth search of local banks during the week (city office shows full parking and sun angle is early afternoon) show perhaps 6-8 cars per bank. Banks just do not generate traffic. What is your local code standard for financial institution parking?
