A parking lot is a paved area used for the storage of motor vehicles, either as an accessory use serving a nearby business or as a standalone commercial operation. Standalone commercial parking lots require C (Commercial) or I (Industrial) zoning. Accessory parking lots that serve an existing business are typically permitted as part of the primary use and do not require separate zoning approval.
Most parking lots are accessory to another use, providing required parking for a retail store, office building, restaurant, or other business. These accessory lots are approved as part of the primary use's site plan and must meet the parking standards in the zoning code (number of spaces, dimensions, landscaping, accessibility, lighting). No separate zoning action is needed for an accessory parking lot.
A commercial parking lot that charges fees and operates as a standalone business is a different use entirely. Commercial parking operations are most common in downtown areas, near airports, sports venues, and convention centers, and in other high-demand parking locations. These operations require commercial zoning and may need a conditional use permit, particularly in zones where a surface parking lot as the primary use of a property is discouraged in favor of building development.
Parking lots are subject to extensive design standards regardless of whether they are accessory or commercial. Common requirements include minimum stall dimensions and aisle widths, ADA accessible spaces (number and location based on total lot capacity), landscaping islands and perimeter landscaping (many codes require one shade tree per 10 to 15 parking spaces), lighting standards including maximum height and light spillover limits, stormwater management (parking lots create large impervious surfaces that generate significant runoff), and screening along property boundaries adjacent to residential uses.
Stormwater management is increasingly important for parking lots. Many jurisdictions now require permeable pavement, bioswales, rain gardens, or detention basins to manage runoff from parking surfaces. These requirements add cost but address the environmental impact of large impervious surfaces on local waterways and drainage infrastructure.
In many cities, surface parking lots are being redeveloped into buildings as land values increase and parking demand shifts. Converting a parking lot to a building requires standard development approvals for the new use. Conversely, converting a building site to a surface parking lot may face opposition from planning departments that prefer building development over surface parking in commercial districts. Some downtown zones prohibit new surface parking lots entirely, requiring structured parking or shared parking arrangements instead.
Start by confirming the zoning on your target property. You can look up your property's zoning on ZoningPoint.com to identify the current classification. For accessory parking, verify that your lot design meets the parking standards in the zoning code. For a commercial parking operation, contact the planning department to determine whether a standalone parking lot is a permitted use in the zone and what conditional use or site plan approvals are required. Engage a civil engineer to design the lot to meet stormwater, grading, and accessibility standards.
It is important that you look up the specific zoning type for your parcel of land, because every jurisdiction has their own unique zoning and this is just a generalization.
