Frequently Asked Questions

What is a standard parking ratio?

Office: 3-4 spaces/1000 sq ft. Retail: 4-5 spaces/1000 sq ft. Medical: 5+ spaces/1000 sq ft.

Why does it matter?

Tenants require adequate parking for employees and customers. Too few spaces can hurt leasing; too many wastes land and money.
