Key Takeaways
- County fair vendor placement maps prevent duplicated placements and last-minute fixes by uniting vendor data, zone rules, and electrical needs in one to-scale plan.
- Begin by reviewing vendor applications and priority rules, then import an accurate aerial or CAD map so every booth reflects real-world dimensions and constraints.
- Define clear vendor zones, traffic flow, and emergency lanes early, keeping food, retail, and craft areas separate and maintaining minimum widths for pedestrian and vehicle access.
- Calculate booth sizes in standard increments (10×10, 10×20, 20×20 ft), confirm trailer footprints, and cross-check product categories to prevent duplication before contracts are signed.
- OnePlan replaces fragmented spreadsheets and static PDFs with a live, collaborative, to-scale map that auto-generates permit-ready exports and a Bill of Quantities. Book a demo to see how much easier planning becomes.
How to Create a County Fair Vendor Placement Map
Step 1: Set Vendor Priority Before You Place a Single Booth
Establish who gets placed first before any booth touches the map. Many county fairs give returning vendors priority and evaluate applicants on product uniqueness and quality, with final placements often at the organizer’s discretion. The checklist below captures the core details you need upfront so priority decisions stay consistent and defensible.
Your checklist for Step 1:
- Confirm which vendors are returning and in good standing
- Flag product categories where duplication must be avoided
- Note electrical requirements per application (30 AMP, 50 AMP, 100 AMP)
- Record minimum space requirements each vendor has requested
- Set your application deadline and contract-return date
Step 2: Import a Current, Permit-Ready Base Map
Start with the most current aerial or satellite image of your fairgrounds. If you have an existing site plan such as a PDF, a drone photo, or a CAD-derived file, convert it to a .png file and import it into your planning platform so you can build directly on top of it. Outdated GIS imagery or a Google Earth screenshot with shapes dropped on top does not meet most permitting standards. The City of Raleigh’s special-event guidance explicitly states that screenshots of a map with no additional details are not accepted for permitting. The following checklist ensures your base map meets those expectations and reflects current site conditions.
Your checklist for Step 2:
- Obtain the most recent aerial image or site plan of the fairgrounds
- Convert any existing PDF or CAD file to .png for import
- Confirm the map reflects current structures, utilities, and access points
- Mark fixed constraints such as buildings, trees, slopes, utility hookups, and hydrants
Step 3: Map Vendor Zones and Safe Traffic Routes
Divide the fairgrounds into named zones before assigning individual vendors. Separate food and beverage from retail and craft areas to simplify inspections and avoid cross-contamination. Within each zone, keep high-traffic anchor vendors distributed across the site rather than clustered at one entrance, because spreading popular vendors across the site improves foot-traffic distribution and reduces bottlenecks. After zones are defined, set lane widths that support both pedestrian flow and emergency access. Main thoroughfares should be at least 10 feet wide, secondary paths at least 6–7 feet, and emergency vehicle routes shall be a minimum of 20 feet wide and unobstructed. Requirements vary by state and county, so always confirm fire-lane widths with your local fire marshal.
Your checklist for Step 3:
- Label each zone by vendor type such as food, retail, craft, non-profit, or sponsor
- Draw primary pedestrian routes and confirm they meet minimum widths
- Mark emergency vehicle access lanes and keep them unobstructed
- Identify load-in routes separately from live-event pedestrian paths
- Place first aid, restrooms, and ATMs on the map before vendor slots
Step 4: Set Standard Booth Sizes and Zone Capacity
Use imperial measurements throughout so pricing and layouts stay consistent. The most common county-fair booth increments are 10×10 ft (100 sq ft), 10×20 ft (200 sq ft), and 20×20 ft (400 sq ft), and many fairs use these as base pricing units. For example, Duchesne County Fair prices food booths at 10×20 ft and 20×20 ft and requires vendors to confirm trailer dimensions tongue-to-bumper. Because trailers rarely match standard increments exactly, always measure the full footprint, including tongue, awning, tie-downs, and any side extensions, to decide which booth size to assign. As with fire-lane widths, confirm local buffer rules with your fire marshal and health department, since these extra clearances change how many booths each zone can hold.
Your checklist for Step 4:
- Record each vendor’s full footprint in feet, including awnings and tongues
- Assign booth sizes in standard increments such as 10×10, 10×20, or 20×20 ft
- Calculate total square footage needed per zone
- Confirm electrical capacity per zone against vendor load requirements
- Apply any mandated buffer distances around food stalls and other risk areas
Step 5: Place Vendors and Eliminate Product Duplication
Place vendors one by one once zones and booth sizes are set. Start with returning priority vendors, then fill remaining slots with new applicants. Check for product duplication in each zone as you go, because organizers often focus on quality and want to avoid oversaturating any category. A live, to-scale map makes duplication visible instantly. If two funnel-cake vendors end up in the same zone, you see it before contracts are signed and can adjust placements.
Your checklist for Step 5:
- Place returning vendors first, then assign spaces to new applicants
- Cross-check product categories within each zone for duplication
- Confirm each booth fits its assigned space at scale
- Verify electrical hookup proximity for each assigned slot
- Flag any vendor whose footprint exceeds the assigned space
Step 6: Coordinate the Map With All Departments
A vendor placement map only works when every stakeholder uses the same version. Operations, parks and recreation, the health department, the fire marshal, and contracted vendors all need to see and sometimes edit the plan. Eagle Mountain City Events Manager Dawn Hancock describes the shift: “Gone are the days of creating separate layouts for fire, police, facilities, and other departments. Now I can create a single, all-encompassing layout,” cutting planning time from 8–10 hours down to a few hours per event. Real-time collaboration on one live plan replaces the cycle of emailed PDFs and version confusion. The checklist below turns that collaboration into a simple, repeatable workflow.
Your checklist for Step 6:
- Share the live plan with operations, parks, fire, and health departments
- Provide view-only access to vendors so they can confirm their assigned slot
- Collect feedback in one place rather than across separate email threads
- Update the map in real time as changes are approved

Step 7: Export Maps and Quantities for Permits and Vendors
The finished map needs to serve permitting, vendor communication, and on-site operations. Permit applications, vendor confirmation packets, and event-day teams all rely on clear, professional outputs. Raleigh’s special-event site-plan requirements call for legible, close-to-scale site plans showing streets, structures, fire lanes, fencing, exits, and a key, which reflects the level of detail many jurisdictions expect. A Bill of Quantities converts every object on the map into an exportable inventory of tent stakes, linear feet of crowd barrier, electrical hookups, and more so procurement and contractors stay aligned.
Your checklist for Step 7:
- Export a high-resolution map, print-ready up to A0 size, for permit submission
- Generate a Bill of Quantities listing all infrastructure by type and quantity
- Send each vendor a map showing their assigned booth location
- Prepare a separate load-in map showing vehicle access routes and timing
- Keep a live version of the plan available for day-of operations updates
Why OnePlan Is the Modern Alternative for Fair Maps
Most county fair vendor maps are still built in PowerPoint, Excel, Canva, Photoshop, Google Maps, or internal static, top-view screenshots and plan files. None of those tools are to scale, none support real-time collaboration, and all of them fragment into emailed versions that go stale the moment someone makes a change. The impact shows up on setup day as a food trailer that does not fit its slot, a fire lane that has been accidentally blocked, or a permit submission rejected because the map lacks required detail.
OnePlan serves as a single source of truth that replaces all of those tools: PowerPoint, Excel, Canva, Photoshop, Google Maps, and static screenshots. Its base layer is a live, zoomable satellite or street map built on leading GIS technology, and every object placed on it stays accurately to scale as you zoom. Drag a 10×20 ft food booth onto the fairgrounds and it occupies exactly 200 square feet on the map. The area calculator instantly confirms how much space remains in each zone. The auto-generated Bill of Quantities turns the finished map into a procurement list without any re-keying.
The Cheese & Chilli Festival, which manages food vendors across several annual events, replaced Excel, PowerPoint, and Google Maps with OnePlan. They report, “With the software we were using before, the ability to scale wasn’t great. We couldn’t rely on it to be accurate and we would often get to site and have to make changes to layout due to plans not being to scale.” The National Cherry Festival, which has an annual attendance of 500,000, rates OnePlan “10 out of 10” as the best layout software on the market. OnePlan has powered more than 200,000 events across 150 countries, from community fairs to the Olympics.
For county fair teams specifically, the platform delivers:
- To-scale booth placement with exact imperial dimensions, removing guesswork
- Duplication checks visible at a glance on one shared map
- Real-time collaboration so operations, fire, health, and vendor teams work from the same plan
- Auto-generated Bill of Quantities for permit submissions and supplier orders
- High-resolution map exports ready for permit applications and vendor packets
- Fewer site visits, because layouts are validated remotely before setup day
Frequently Asked Questions
How far in advance should a county fair start building its vendor placement map?
Most county fairs open vendor applications three to six months before the event. The placement map should be started as soon as the fairgrounds layout is confirmed, ideally at the same time applications open, so that zone capacities and electrical hookup locations are known before acceptance decisions are made. Building the map early means you can tell applicants exactly what space sizes are available rather than discovering conflicts after contracts are signed.
What booth sizes should we plan for, and how do we handle trailers that do not fit standard increments?
Use the standard booth increments described in Step 4 as your baseline. For food trailers, always measure tongue-to-bumper and include awnings, tie-downs, and any side extensions in the total footprint. If a trailer exceeds a standard increment, assign the next size up or charge for additional footage in 5-foot increments, as many fairs do. Record every vendor’s full footprint on their application so the map reflects the actual space each booth will occupy on setup day. Confirm local spacing and buffer rules with your fire marshal and health department so those clearances appear on the map as well.
How do we prevent two vendors selling the same product from ending up in the same zone?
The most reliable method is to tag each vendor application with a product category before placing anyone on the map. As you assign booths zone by zone, check the category list for that zone before confirming each placement. A live, to-scale map makes this visible in real time. If two similar vendors end up adjacent, you see it immediately and can reassign before contracts go out. Some fairs also hold exclusive category rights for certain products, which should be noted on the map as reserved zones.
What documentation does a vendor placement map need to include for permit submission?
Requirements vary by city, county, and state, so always check with your local permitting authority. As a general guide, many jurisdictions require a legible, close-to-scale site plan that shows a north-pointing compass, all street names, building footprints and exits, tent and temporary structure locations with dimensions, food truck and vendor positions, stage locations, first aid stations, restrooms, generators, fire extinguishers, and clearly marked emergency access lanes. A Bill of Quantities listing all infrastructure by type and quantity supports contractor coordination and can accompany the map in permit submissions.
Can a small county fair with only 30–40 vendors benefit from a digital planning tool?
Yes. Even at 30–40 vendors, the coordination between the events team, parks department, fire marshal, and individual vendors creates enough version-control complexity to cause errors on setup day. A to-scale digital map removes the back-and-forth of emailed PDFs, confirms that every booth fits its assigned space before setup begins, and produces a professional permit-ready export in one click. OnePlan’s first event is free, up to 25 objects, and paid plans scale from there, so a small fair can access the same accuracy and collaboration tools as a large state fair without a significant upfront investment.
Conclusion: Build Your County Fair Vendor Map With Confidence
A well-executed county fair vendor placement map follows a repeatable seven-step process. Review applications and priority rules, import an accurate base map, define zones and traffic flow, calculate booth sizes in feet, assign vendors without duplication, collaborate with every department on one live plan, and export professional maps and a Bill of Quantities for permits and vendors. Each step builds on the last, and the whole process becomes faster and more accurate when it happens on a single, to-scale, collaborative platform instead of across disconnected spreadsheets and static files.
OnePlan is built for exactly this workflow. The platform consolidates the disconnected tools described earlier into a single live map where every booth, lane, and infrastructure item stays to scale, every stakeholder works from the same plan, and every output, from permit maps to supplier orders, is generated automatically from the work you have already done.
