How to Lay Out a Parking Lot Vendor Event

A good parking lot vendor event layout uses the existing stall striping as a grid: vendors set 10x10 tents at the front of the stalls, facing the drive aisle, and the drive aisle becomes the shopper aisle. Keep fire lanes and building exits open, weight every tent because you can't stake into asphalt, put food trucks and generators where the fire marshal approves and block every vehicle entrance with barriers. Mark an accessible route from parking to the aisles. This guide covers each step and works through a layout for an example lot.

Measure the Lot and Its Striping

A parking lot is already a grid. A typical 90-degree stall is roughly 9 ft wide x 18 ft deep, and two-way drive aisles between rows are often about 24 ft wide, but every lot differs, and angled stalls change the math. Measure your lot rather than assuming. Mark on your drawing:

• Stall rows and drive aisles, with their real widths and lengths.
• Vehicle entrances and exits, and which ones will be closed during the event.
• Fire lanes and fire hydrants, which must stay clear.
• Building entrances and exits that open onto the lot.
• Curbs, islands, light poles and trees, which break up rows.
• Drains and slope. Lots slope toward drains, and water pools there in rain. Don't put a food truck or a jewelry vendor in the low spot.
• Accessible parking stalls and curb ramps.

An aerial image or the property's site plan is a good start, but walk the lot with a measuring wheel to check it. For general principles that apply to any market, see our guide to vendor market layout.

Use the Stalls as Your Grid

The simplest way to set up vendors in a parking lot is to turn each drive aisle into a shopping street:

• Tents face the drive aisle, set at the front of the stalls. A 10 ft deep tent in an 18 ft stall leaves about 8 ft behind for vendor storage, coolers and a hand truck.
• The drive aisle is the shopper aisle. At about 24 ft, it is wide enough for browsing, strollers and crowds in front of popular vendors.
• Back-to-back stall rows become back-to-back vendor rows, with storage space shared behind them.
• The striping is your layout guide. Vendors and volunteers can find spaces by stall lines, which saves marking out the lot.

A 10x10 tent is wider than a 9 ft stall, so tents don't line up one per stall. A planning assumption is about 8 tents for every 10 stalls of frontage, which leaves small gaps between tents for weights and for people to step through. Number spaces along each row and mark them with chalk or cones on setup morning.

Other space sizes

Some vendors want 10x20 spaces, and some markets sell table-only spaces with no tent. Put larger spaces at the ends of rows, where they don't break the rhythm of the grid. The event tent size calculator helps if you are renting a larger tent for seating, a stage or a sponsor area.

Keep Fire Lanes and Exits Clear

The fire marshal decides what has to stay open, and in a parking lot that usually includes a fire apparatus lane that reaches the building and the event area. Many fire codes use 20 ft as the minimum width for fire apparatus access, but your fire marshal decides the width and the route. Plan for:

• A marked fire lane with no tents, tables, coolers or signs in it.
• Clear access to hydrants and the building's fire department connection.
• Clear building exits. Tents can't sit in front of any door that opens onto the lot.
• Space between tent rows if the fire marshal sets a maximum length for a continuous row of tents.

Send your drawing to the fire marshal before you sell spaces, because moving a whole row after vendors have paid is much harder than moving it on paper.

Require Tent Weights

You can't drive stakes into asphalt, and an unweighted pop-up tent can lift in a gust and hurt someone. Every tent needs weights on every leg. Many markets require at least 40 lb per leg, and some cities or fire marshals require more. Put the rule in the vendor agreement, say what counts as a weight (sandbags, water barrels or purpose-made tent weights, not a bucket of rocks tied with string), and check every tent before the market opens. Tell vendors that tents come down if winds pass a set speed.

Place Food Trucks and Generators

Food trucks need more room than tents. They need length for the truck, a serving side facing shoppers, space for a queue that doesn't block the aisle and space behind or beside them for a generator or propane. Common rules:

• Give food its own row or zone, usually along the edge of the lot, so trucks can drive in and out without crossing vendor rows.
• Point generators away from shoppers and tents, and keep exhaust away from seating and building air intakes.
• Ask the fire marshal for spacing between trucks, between generators and tents, and around propane. These rules vary, so don't guess.
• Add seating, shade and trash near the food row, so people don't eat in the vendor aisles.

Block Vehicle Access

A parking lot is built for cars, and drivers will try to use it. Close every vehicle entrance during market hours with barriers that a car can't drive through by mistake, such as water-filled barriers or parked vehicles, and add signs at each entrance well before the lot. Keep one entrance staffed for emergency vehicles. Plan where vendors park once they unload, and where shoppers park, so neither group ends up circling the market. Set a hard cutoff time for vendor vehicles on setup morning, and don't let any vehicle move inside the market until it closes.

Mark an Accessible Route

• Keep accessible parking in use or replace it nearby, and keep the route from it to the aisles level and clear.
• Use curb ramps where the route crosses a curb, and don't block them with tents.
• Cover cables with low, beveled cable ramps where they must cross a path.
• Avoid the steepest slopes and drains for the main route.
• Add shaded seating along the route. Asphalt gets hot in summer sun.

Worked Example: A Parking Lot Market

Here is the method with round numbers. The lot is an example, and the stall, aisle and fire lane widths are planning assumptions.

• Lot: 240 ft x 200 ft, with stall rows running the long way.
• Parking modules: three modules of stall row + 24 ft drive aisle + stall row, each 18 + 24 + 18 = 60 ft, take 180 ft of the depth.
• Fire lane: the remaining 20 ft along one long side stays clear as the fire lane.
• Row length: a 24 ft drive at each end leaves 192 ft of stalls per row, or 21 stalls.
• Cross aisle: removing 2 stalls in the middle of each row splits it into two halves of about 85 ft, each fitting about 7 tents, so 14 tents per row.
• Rows: 6 stall rows. Five carry tents, so 5 x 14 = 70 tents.
• Food row: the sixth row, along the lot edge opposite the fire lane, holds about 5 food trucks with generators behind them, at whatever spacing the fire marshal sets.
• Services: giving up 4 tent spaces near the entrance for an information tent, first aid and accessible drop-off leaves about 66 tent spaces and 5 food trucks.

Treat the result as a starting point. Light poles, islands and a sloped corner always cost a few spaces, and the fire marshal may ask for more space around the food row. Place every space on a to-scale drawing to get the real count.

Plan Load-In and Load-Out

Parking lot markets load in fast when vendors can drive to their space. Assign arrival windows by row, starting with the rows farthest from the entrance, so early arrivals don't block later ones. Vendors unload into their space, then move their vehicle to the vendor lot before the cutoff. Reverse the order at close, and don't let vehicles back into the lot until shoppers are gone.

Draw It to Scale and Share It

A to-scale map is what the fire marshal, the property owner and your vendors all need to see. With event floor plan software you can trace the lot from a site plan, place tent spaces and food trucks on the stall grid and update the map as spaces sell. An interactive floor plan lets vendors see which spaces are open, and lets shoppers find food, restrooms and their favorite vendors on the day.
