The State of Florida Department of Community Affairs does not review the design of parking areas for individual buildings, nor does any other state agency. Parking areas are regulated by either municipal or county zoning codes (depending on whether the site is in an incorporated or unincorporated area). Parking regulations will include requirements for so many spaces per area occupied by a certain type of use (for example, one space per 30m2 of retail use), along with specifics on stall size, layout, aisle width, number of curb cuts, amount of landscaping, hardscaping, lighting, pavement surface, valet parking, parking for the disabled, shopping cart corrals, and other elements. These requirements vary from place to place, with rural and lower income areas typically having more lenient regulations (i.e. few or no landscaping, access control and/or paving requirements).
The expansion of parking areas in response to a change in the use, intensity or building size on a site is also regulated by zoning regulations. Zoning regulations governing parking in pedestrian-oriented areas, such as large city business districts, may include on-street parking in calculating required parking, and often require fewer spaces per use. A new Applebee’s in Lake Mary may require one off-street parking space per table plus one off-street parking space per employee on the busienst shift, while a new restaurant with the same amount of tables and employees in downtown Orlando will require no off-street parking.
Zoning regulations will not account for business popularity. Usually, codes require far more spaces than a use will ever need. This results in large, ugly parking lots that stay empty most of the time. Urban planners in the United States are fleeing from “worst case scenario” parking requirements, and promoting more reasonable standards; engineers are resisting them, assuming that parking demand for a business will be like the day after Thanksgiving every day, everywhere. Despite the amount of parking available at most businesses, some places will be crowded with cars; they’re a victim of their success. If you don’t like it, take your patronage elsewhere.
“Parking lanes,” usually known as drive aisles, range from 3.5 m wide, for a one way aisle accessing spaces angled at 60 defrees, to 8.5 m wide for a two way aisle accessing spaces angled at 90 degrees. Drive aisle widths are regulated in municipal and county zoning regulations.
(Of course I know this stuff. I’m writing a new zoning/subdivision.architectural design code for a Florida city.)
