County Fair Site Map Requirements for Every Permit

Written by: Paul Foster, Founder, CEO, OnePlan

Key Takeaways

• A county fair site map must satisfy five departments: fire marshal, health, emergency services, zoning, and ADA/public safety, each with its own checklist.
• Fire marshal reviewers focus on 20-foot emergency access lanes, tent setbacks, generator placement, and fire extinguisher locations, all drawn to scale.
• Health departments verify restroom counts, ADA-compliant units, handwashing ratios, and vendor separation distances, often needing 60–90 days for review.
• Emergency services and ADA reviewers need continuous accessible routes, gate widths, assembly points, first-aid stations, and AED locations clearly marked and unobstructed.
• OnePlan lets you build a single, geo-accurate site map that meets every department’s requirements, so book a free demo to see how it streamlines permit approval.

Core Requirements for a County Fair Site Map

A county fair site map is a scaled, department-ready drawing submitted as part of a special event permit application. Five core departments review it: the fire marshal (emergency access, tent setbacks, extinguisher placement), the health department (sanitation counts, food-vendor separation, potable water), emergency services (ambulance routes, assembly points, gate widths), zoning and planning (property boundaries, setbacks, utilities, impervious surface), and ADA/public safety (accessible routes, ramp slopes, first-aid locations). Each department has distinct map requirements, and a single omission can trigger a rejection across all of them.

Fire Marshal Checklist for County Fair Site Maps

Fire marshal reviewers need to verify that emergency vehicles can reach any point on the fairgrounds and that ignition risks are controlled. The following checklist reflects requirements documented by California’s Office of the State Fire Marshal (OSFM) and other jurisdictions. Requirements vary by jurisdiction, so confirm details with your local authority.

• Emergency access lanes: a minimum 20-foot-wide clear path for fire apparatus, shown to scale throughout the site (illustrative: California OSFM specifies this width)
• Exit locations and aisle widths: every exit marked with its measured width, with the path of travel to each exit clearly drawn
• Tent setbacks: California Fire Code (enforced by OSFM) requires tents and membrane structures to be located at least 20 feet from buildings, except when specific conditions on floor area, egress, and fire access are met or when approved by the enforcing agency, with dimensions, wall status, and fire rating noted in a legend
• Generator and cooking locations: generators shown on hard, fenced surfaces with cable routes marked, and food trucks and cooking tents labeled with power source or gas type
• Fire extinguisher placement: each unit marked by location on the map
• Open-flame notes: any open flame or fire performance area identified with placement and duration
• Electrical panels: location of all electrical panels shown
• Stages and elevated platforms: dimensions, make or model, and stair or ramp access indicated

OnePlan’s drag-and-drop library includes to-scale tents, generators, fire extinguisher icons, and stage objects. You place them on a live satellite map and immediately see whether the 20-foot access lane fits before you submit, not after a rejection letter arrives.

Health Department Rules for Sanitation and Food Vendors

Once fire marshal requirements are addressed, the next critical review usually comes from the health department. Health departments review the site map to confirm that sanitation infrastructure is adequate, correctly placed, and serviceable. LA County, for example, requires a site map detailing the locations and quantities of toilets, handwashing stations, and related facilities as part of the event permit application that covers unit counts, ADA-compliant units, handwashing ratios, a site placement diagram, and a service schedule. Requirements vary by jurisdiction.

• Restroom count and placement: total portable toilet units shown by location, distributed so no attendee walks more than 3–4 minutes to reach a bank
• ADA-accessible units: at least 5% of total units must be ADA-compliant (minimum one unit), placed on firm, hard-path surfaces and connected to the accessible route
• Handwashing stations: LA County Public Health specifies one handwashing sink for every four public toilets at community events, each supplying warm water, liquid soap, single-use towels, and a trash container, with the ratio confirmed locally
• Potable water and grey-water locations: all potable water supply points and grey-water tanks shown with labeled function
• Vendor separation distances: portable toilets must maintain at least 50–100 feet of separation from food preparation and serving areas (illustrative; confirm locally)
• Service road access: pump-truck access routes behind each restroom bank shown on the map, wide enough for service vehicles
• Servicing schedule: health departments expect servicing schedules documented alongside the site map, not left to verbal assurances on inspection day

OnePlan’s area and perimeter calculator lets you outline restroom zones and confirm separation distances from food-vendor clusters before a single unit is ordered. The auto-generated Bill of Quantities then exports a toilet and handwashing-station count directly to your permit package.

Emergency Access and Egress Standards

Emergency services reviewers need to trace every vehicle route from the public road to any point on the fairgrounds, and back out again, without obstruction. Use OnePlan’s free exit calculator and arrival calculator to model exit capacity and entry queue length for your emergency access submission.

• Fire lanes and ambulance routes: drawn to scale with labeled widths throughout the site
• Gate widths: every vehicle entry and exit gate measured and labeled on the map
• Vehicle ingress and egress: separate entry and exit flows shown, with turning radii that accommodate emergency vehicles
• Assembly points: designated gathering areas for evacuees marked with the internationally recognized symbol
• Helicopter landing zones: helicopter landing zones marked clearly on all emergency services site maps and communicated to the local airspace management authority before the event
• Overflow areas: overflow areas included in the site design to prevent audience members from blocking roads or designated emergency escape routes

The calculators mentioned earlier produce defensible figures for your emergency access submission and support conversations with local emergency services.

ADA and Public-Safety Mapping Requirements

Event site planning must prioritize mapping accessible routes before placing vendor tents, stages, or barricades so the path remains unobstructed from accessible parking through to exits.

• Continuous accessible route: firm, stable, slip-resistant path connecting accessible parking, entrances, activity areas, restrooms, and exits, with a minimum 36-inch clear width throughout
• Gate and passage widths: all gates along accessible routes must maintain at least 32 inches of clear width
• Temporary ramp slopes: no steeper than 1:12, with landings at top and bottom and edge protection shown on the map
• ADA restroom minimum: at least 5% of total portable toilet units ADA-compliant (minimum one), placed on hard-path surfaces and distributed across clusters rather than grouped in one location
• Temporary surfacing: grass or gravel sections of the accessible route require temporary flooring panels or rubber mats shown on the map
• First-aid station locations: first-aid stations must be shown using the internationally recognized first-aid cross symbol, with the main medical facility accessible for wheelchairs and ambulance cots
• AED locations: AED locations should be included on all site maps distributed to event staff

Zoning and Utilities Details Reviewers Expect

Zoning reviewers confirm that the event footprint respects property boundaries, setbacks, and land-use conditions. Caroline County, Virginia requires that event boundaries at minimum meet the required setbacks for the zoning district, with greater setbacks possibly required for public health, safety, or welfare. Requirements vary by jurisdiction.

• Property boundaries: full boundary polygon with dimensions that close correctly, not derived from Google Maps or real estate listings
• Setbacks: distances from all proposed structures to property lines, measured from the outermost point including eaves and overhangs
• Generator locations: shown on a protective, fenced surface with cable routes marked and spill-kit location noted
• Electrical panel locations: all panels labeled on the map with voltage and amperage for each piece of equipment
• Lighting details: Caroline County requires outdoor lighting to be downward directed with shielding details shown to prevent glare beyond the property line (illustrative; confirm locally)
• Impervious surface notes: total square footage and percentage of lot area covered by structures, driveways, and hardscape
• Utility shut-off locations: electrical breaker panels, water main valves, and gas valves should be clearly labeled on the map, with access restricted to trained personnel

Common Map Rejection Reasons and How to Avoid Them

The most common site plan rejection triggers are missing or inaccurate boundary information, omitted scale indicators, and non-to-scale elements. These problems stay hidden when you work in PowerPoint, Canva, or a static screenshot.

Rejection Trigger	Why It Fails Review	How OnePlan Prevents It
Missing scale bar or written scale	Reviewers must be able to measure distances on the drawing and confirm they match labeled dimensions	Every OnePlan export includes a to-scale map on a live satellite base, so distances are geo-accurate at any zoom level
Missing north arrow	Reviewers rely on it to verify setbacks relative to street frontage and orient the plan within the neighborhood	OnePlan’s map base is geo-referenced, so orientation is inherent, and a north arrow can be added to the exported legend
Non-to-scale or hand-drawn elements	Fire lanes, tent setbacks, and exit widths cannot be verified if objects are not drawn to their actual dimensions	Every object in OnePlan uses the to-scale approach described earlier, so a 20-foot fire lane measures exactly 20 feet on the map
Static screenshot submitted as site plan	Boundaries derived from Google Maps or real estate listings rather than a recorded survey are a top rejection trigger	OnePlan exports high-resolution PNG maps (up to A0, print-ready) built on GIS-accurate satellite imagery, not screenshots
Omitted property boundaries or setbacks	Zoning reviewers cannot confirm compliance without a complete boundary polygon and setback measurements	You draw the boundary polygon in OnePlan, and the area calculator instantly returns dimensions for the title block
Incomplete title block	A complete title block must include property address, owner and preparer details, date, revision history, scale, and north arrow	You export data and map together, then add title-block details to the accompanying legend before printing

Permit Submission Sequence and Realistic Timelines

Multi-department permit reviews usually run sequentially, so a delay at one desk pushes every downstream approval. Sanitation plans should be submitted 60–90 days before the event, as health department reviews can take two to four weeks and revisions add more time. Linn County, Iowa recommends applications at least 60 days before the event start date and charges a $500 expedited fee for submissions received 14 days or fewer before the event (illustrative; confirm with your local authority).

1. 60–90 days out, pre-application meeting: holding a pre-application meeting with planning staff reduces rejection risk by surfacing jurisdiction-specific requirements not obvious from published checklists. A draft OnePlan map gives staff a concrete reference point to identify potential issues before formal submission.
2. 45–60 days out, primary application submission: submit the scaled site map, sanitation plan, severe weather plan, and certificate of liability insurance together. Charles County recommends at least 45 days’ lead time to allow for review and coordination (illustrative).
3. Fire marshal review: usually the first or a concurrent department sign-off, with likely requests for revised access-lane widths or tent setback corrections.
4. Health department review: sanitation counts, handwashing ratios, and food-vendor separation distances verified against the site map. Alameda County Environmental Health requires complete applications at least 30 working days prior to the event, and incomplete applications are rejected (illustrative).
5. Zoning and planning review: boundary polygon, setbacks, impervious surface, and lighting details confirmed.
6. Emergency services sign-off: ambulance routes, gate widths, and assembly points verified.
7. ADA/public safety review: accessible route continuity, ramp slopes, and ADA restroom placement confirmed.
8. Final multi-department approval and permit issuance: digital submissions are increasingly accepted, so confirm format (PDF, PNG, or paper) with each department before exporting.

Because OnePlan is a live plan, revisions requested at step three do not require rebuilding from scratch. You move an object, recalculate the affected area, and re-export a print-ready map in minutes.

Frequently Asked Questions

What file format should I submit my county fair site map in?

Most jurisdictions accept high-resolution PDF or PNG files for digital submissions, though some fire marshal and zoning offices still require paper prints at a specified scale (commonly 1 inch = 20 feet or 1 inch = 40 feet). Confirm the accepted format with each reviewing department before exporting. OnePlan exports print-ready, high-resolution PNG maps that can be printed at up to A0 size, which makes them suitable for both digital upload and large-format printing at any copy shop.

Do all five departments review the same site map, or do I need separate drawings?

In most counties, a single comprehensive to-scale site map is submitted with the primary application and routed to each department for its specific review. Some jurisdictions request a simplified version for public display or a separate route map for emergency services. The safest approach is to build one complete map that satisfies every department’s checklist, then export copies for each reviewer. OnePlan’s single live plan means every department sees the same up-to-date drawing, not five different versions emailed at different times.

How far in advance should I submit my county fair permit application?

A 60-day minimum lead time is the most commonly cited benchmark across jurisdictions, with 90 days recommended when health department sanitation reviews and fire marshal inspections run concurrently. Some counties charge significant expedited fees for late submissions. Pre-application meetings with planning staff, held 75–90 days out, reduce the risk of first-round rejections that eat into your timeline.

What is the minimum number of ADA-accessible portable toilets required at a county fair?

The widely cited standard is at least 5% of total portable toilet units must be ADA-compliant, with a minimum of one accessible unit regardless of event size. ADA units must be placed on firm, hard-path surfaces, distributed across restroom clusters rather than grouped in one location, and connected to the accessible route by a continuous, slip-resistant path. Always confirm the exact ratio with your local health department, as requirements vary by jurisdiction.

Can I use OnePlan to produce a site map that satisfies fire marshal requirements?

Yes. OnePlan’s drag-and-drop library includes to-scale tents, generators, stages, fire extinguisher icons, and emergency access lane markings. Because every object stays accurately to scale on a live satellite map, a 20-foot fire lane measures exactly 20 feet on the exported drawing, which provides the verifiable accuracy fire marshal reviewers require. The area and perimeter calculator confirms setback distances, and the high-resolution PNG export is print-ready for submission. OnePlan is not a regulatory authority, so always verify your final map against your local fire marshal’s specific checklist before submitting.

What happens if a department requests revisions after my initial submission?

With a static PDF or hand-drawn sketch, a revision request usually means starting over. With OnePlan, you move the flagged object, recalculate the affected area, and re-export a corrected print-ready map, often in under an hour.

Conclusion

County fair permit approvals depend on a to-scale, department-ready site map that gives every reviewer exactly what they need to sign off without sending it back. Static screenshots, hand-drawn sketches, and PowerPoint layouts fail that test regularly, not because the event is poorly planned, but because the map cannot prove it.

OnePlan replaces guesswork with a live, geo-accurate plan where every tent, fire lane, restroom cluster, accessible route, and generator is placed to scale on a real satellite map. The area calculator confirms your setbacks. The Bill of Quantities counts your infrastructure. The high-resolution export goes straight to the fire marshal, health department, zoning office, and emergency services, all from one plan, built once, updated in real time.

Eagle Mountain City cut event planning from 8–10 hours down to a few hours per event and reported a 5x return on investment after switching to OnePlan. The National Cherry Festival uses it to plan for 600,000 attendees. From a single county fair to the Olympics, the tool stays the same: accurate, collaborative, and built for people who plan events, not engineers.
