Key Takeaways
- A public market permit approval map is a dimensioned, to-scale site plan that shows vendor stalls, fire lanes, access routes, and other layers required by each city’s permitting authority.
- Boston, San Francisco, New York City, Chicago, Los Angeles, Austin, Philadelphia, and Seattle each have distinct timelines, required map layers, and export specifications that you must follow to avoid first-review rejection.
- Common rejection triggers include missing scale bars, north arrows, title blocks, or incorrect fire-lane widths. OnePlan’s built-in calculators and auto-generated legends prevent these problems before you export.
- High-resolution PNG exports at a minimum of 150 DPI with clearly visible scale bars, north arrows, and legends meet upload requirements for all eight cities covered in this guide.

What Is a Public Market Permit Approval Map?
A public market permit approval map is a dimensioned, to-scale drawing of your proposed market site that you submit to the relevant municipal authority as part of a special-event or temporary-use permit application. It shows the physical layout of the event, including vendor footprints, emergency access lanes, crowd areas, utility connections, and ingress and egress points, so reviewers can confirm the site meets zoning, fire, and safety codes before granting approval. Reviewers use site plans to confirm zoning compliance and life-safety clearances. A screenshot of Google Maps with no dimensions is not a site plan and will be rejected outright.
Eight City Examples, Timelines, and OnePlan Export Settings
The eight cities below represent the largest and most active U.S. public-market permitting environments, and together they show three common regulatory patterns. Boston and Chicago use tiered review systems, Los Angeles and San Francisco offer express tracks for simple projects, and Austin and Seattle publish transparent, data-driven timelines. New York City and Philadelphia sit between these models, with detailed guidance and tools that help you prepare complete submissions. Timelines are typical for temporary-event or special-event permit applications and vary based on completeness of submission and local workload. Produce all OnePlan exports as high-resolution PNG at print-ready quality and convert to PDF only where the portal explicitly requires it.
- Boston: turnaround times vary with minimum advance deadlines of 2 to 6 weeks depending on tier. Export as high-resolution PNG at a minimum of 150 DPI in landscape orientation that matches the city’s Outdoor Public Events Map base.
- San Francisco: permit approvals for temporary events and street closures can take 2 to 6 or more months per SF.gov. Export as high-resolution PNG or PDF per DPW portal specifications and include a graphic scale bar.
- New York City: turnaround times vary via NYC Parks or DOT. Export as high-resolution PNG with a north arrow and title block visible.
- Chicago: DCASE informs applicants of special-event permit approval or disapproval within 35 business days after receiving a complete application per the Special Events Resource Guide. Export as high-resolution PNG and include all layer labels and a legend generated from OnePlan’s legend tool.
- Los Angeles: 4 to 8 weeks is typical, with an LADBS Express track available for qualifying small events. Export as high-resolution PNG with dimensions labeled.
- Austin: turnaround times vary, with permits typically issued within 30 days. Live turnaround data appears on the Austin open data portal. Export as high-resolution PNG.
- Philadelphia: typical turnaround for many residential and building permits is 15 to 20 business days, roughly 3 to 4 weeks, though commercial or complex projects may take longer per City of Philadelphia. Use the Permit Navigator to confirm required documents before exporting. High-resolution PNG is accepted.
- Seattle: typically processes Subject-to-Field-Inspection permits within one working day from the date of filing per SDCI Tip #316, with plan-review targets of 2 to 4 weeks for simple or medium projects and 8 to 12 weeks for complex projects per SDCI FAQs. Export as high-resolution PNG with a scale bar.
Boston Public Market Permit Approval Map
Boston requires public market organizers to submit through the Boston Outdoor Public Event portal, managed by the Office of Consumer Affairs and Licensing. Boston explicitly states that screenshots of a map with no details are not accepted and that applications submitted without a site plan will not be approved.
Required map layers for a Boston public market permit approval map include:
- Vendor stall footprints with dimensions
- 20-foot-wide unobstructed emergency access lanes
- Hydrant clearance zones with at least 10 feet of clearance on both sides of each hydrant from any equipment or object
- Ingress and egress routes clearly labeled
- Property or site boundaries
- North arrow and graphic scale bar
- Title block with event name, date, and organizer contact
Boston provides its own Outdoor Public Events Map as a recommended base layer and publishes site plan examples that show minimum standards. Turnaround times vary for complete submissions. In OnePlan, use the area calculator to confirm your emergency access lane is a full 20 feet wide before export, then export as a high-resolution PNG in landscape orientation.
San Francisco Public Market Permit Approval Map
Boston requires a 20-foot emergency access lane, while San Francisco’s fire code specifies a minimum 14-foot lane with wider lanes required in some situations, which affects how closely you can pack vendor stalls. San Francisco temporary-event and street-closure permits are coordinated through the San Francisco Department of Public Works and, for parks-based markets, SF Recreation and Parks. The San Francisco Department of Building Inspection offers an Over-the-Counter process that issues qualifying permits during the same visit when scope and drawings meet criteria.
Required map layers for a San Francisco public market permit approval map include:
- Vendor and stall footprints with dimensions in feet
- Fire lane and emergency vehicle access routes at a minimum of 14 feet wide, with a wider lane typically required in some instances
- Hydrant and utility clearance zones
- Ingress and egress points labeled
- Property boundaries and setbacks
- North arrow, graphic scale bar, and title block
Permit approvals for temporary events and street closures can take 2 to 6 or more months per SF.gov. Follow the same export process you use for Boston, then include the auto-generated legend and confirm the graphic scale bar is visible at the printed size.
New York City Public Market Permit Approval Map
New York City routes public market and farmers market permits through NYC Parks for park-based markets and the NYC Department of Transportation for street-based events. DOB NOW handles structural and alteration filings where applicable, and Professional Certification by a licensed PE or RA can issue many alteration permits within days.
Required map layers for a New York City public market permit approval map include:
- Vendor stall footprints with dimensions
- Emergency access and fire lane widths at 20 feet wide, as noted above
- Ingress and egress points with widths labeled
- Adjacent street names and curb lines
- Hydrant and utility clearance zones
- North arrow, scale bar, and title block
Turnaround times vary for complete submissions. Follow the same export process as Boston and confirm the north arrow and title block remain clearly visible at the intended print size.
Chicago Public Market Permit Approval Map
Chicago’s Department of Cultural Affairs and Special Events manages special-event permits through the Chicago Special Events portal. Chicago’s Department of Buildings operates a tiered permit system that includes an Easy Permit Process for small work and Standard Plan Review for most commercial projects.
Required map layers for a Chicago public market permit approval map include:
- Vendor and stall footprints with dimensions
- Emergency vehicle access lanes at 20 feet wide, as noted above
- Fire hydrant clearance zones
- Ingress and egress routes labeled
- Site boundaries and adjacent street names
- North arrow, graphic scale bar, title block, and layer legend
Chicago DCASE informs applicants of special-event permit approval or disapproval within 35 business days after receiving a complete application per the 2025 Special Events Resource Guide. Follow the standard export process and use OnePlan’s legend generator to produce a clean, labeled legend as a separate PNG, then attach both files to your submission.
Los Angeles Public Market Permit Approval Map
Los Angeles public market and farmers market permits are coordinated through the Los Angeles Fire Department for fire clearance and the Los Angeles Department of Building and Safety for site plan review. LADBS offers Express Permits for qualifying small projects, which are typically issued the same day at the counter.
Required map layers for a Los Angeles public market permit approval map include:
- Vendor stall footprints with dimensions in feet
- Fire access lanes at 20 feet wide per standard, unobstructed
- Fire hydrant clearance zones
- Ingress and egress points with widths
- Property boundaries and setbacks
- Parking areas with space counts
- North arrow, graphic scale bar, and title block
Average turnaround is 4 to 8 weeks for standard review, with an Express track available for qualifying scope. Follow the standard export process and confirm all dimensions are labeled and the scale bar is visible.
Austin Public Market Permit Approval Map
Austin manages special-event and temporary-market permits through the Austin Special Events Office. Austin publishes live permit turnaround data on its open data portal, which makes it one of the most transparent permitting environments in the country. In Austin, AI-assisted building permit reviews already reduce processing time and allow staff to focus on more complex applications.
Required map layers for an Austin public market permit approval map include:
- Vendor stall footprints with dimensions
- Emergency access lanes at 20 feet wide per standard
- Fire hydrant clearance zones
- Ingress and egress routes labeled
- Site boundaries and adjacent street names
- North arrow, graphic scale bar, and title block
Permits are typically issued within 30 days. Follow the standard export process from OnePlan and check the Austin open data portal before submission to confirm current review timelines.
Philadelphia Public Market Permit Approval Map
Philadelphia coordinates its permitting process through the Department of Licenses and Inspections. Philadelphia launched its Permit Navigator in 2023, and by March 2026 it covered all 190 property-related permit requirements. The tool generates customized guides that list required permits, estimated costs, timelines, and review processes after a short questionnaire. Run the Navigator before preparing your map to confirm which documents your specific market type requires.
Required map layers for a Philadelphia public market permit approval map include:
- Vendor stall footprints with dimensions
- Emergency vehicle access lanes at 20 feet wide per standard
- Fire hydrant clearance zones
- Ingress and egress points labeled
- Property boundaries and setbacks
- North arrow, graphic scale bar, and title block
Philadelphia’s typical turnaround for many residential and building permits is 15 to 20 business days, roughly 3 to 4 weeks, though commercial or complex projects may take longer per the City of Philadelphia. Follow the standard export process from OnePlan and attach the Permit Navigator’s downloadable guide to your submission package.
Seattle Public Market Permit Approval Map
Seattle manages special-event and temporary-market permits through the Seattle Special Events Office and the Seattle Department of Construction and Inspections. SDCI publishes intake-to-issuance medians on its performance dashboard, and Subject-to-Field-Inspection permits issue immediately online for minor work that does not require plan review.
Required map layers for a Seattle public market permit approval map include:
- Vendor stall footprints with dimensions in feet
- Emergency access lanes at 20 feet wide per standard
- Fire hydrant clearance zones
- Ingress and egress points with widths labeled
- Site boundaries and adjacent street names
- North arrow, graphic scale bar, and title block
Seattle typically processes Subject-to-Field-Inspection permits within one working day from the date of filing per SDCI Tip #316. Plan review targets are 2 to 4 weeks for simple or medium projects and 8 to 12 weeks for complex projects per SDCI. Follow the standard export process and confirm the scale bar remains clearly visible at the intended print size.
What Your Submission Map Must Show
Missing or incorrect scale is the single most common reason site plans get rejected, followed closely by missing setback dimensions and no north arrow. These failures occur because reviewers rely on standard engineering scales with scale bars to verify that your fire lanes are actually 20 feet wide and that hydrant clearances meet code. If the scale is wrong or missing, reviewers cannot confirm compliance and your application is rejected immediately. Every public market permit approval map submitted to any U.S. city should include the following elements as a minimum, and each one addresses a common rejection trigger:
- Property boundaries and lot dimensions that match the legal description, not a Google Maps estimate
- Setback lines that show required and actual distances from structures to boundaries
- Vendor and stall footprints that are dimensioned, to scale, and labeled as proposed
- Fire lanes and emergency access routes that are at least 20 feet wide, unobstructed, and clearly labeled
- Fire hydrant clearance zones with at least 10 feet of clearance on both sides of each hydrant
- Ingress and egress routes labeled with widths
- Parking areas with space counts and accessible parking routes shown
- Utility connections with water, electrical, and waste points noted
- North arrow specifying true or magnetic north
- Graphic scale bar and written scale, for example 1 inch equals 20 feet
- Title block with event name, site address, organizer name and contact, date, and sheet number
Site plans are rejected for stating “not to scale” or using inconsistent scales, because reviewers depend on standard engineering scales with scale bars to verify accuracy. OnePlan’s map-based canvas keeps every object to scale automatically, so this failure mode disappears before you export.

Exporting from OnePlan for City Portals
OnePlan exports plans as high-resolution PNG files and generates a separate legend from the built-in legend tool. The following file-naming conventions and settings work well for each of the eight city portals covered in this guide. Portal requirements change over time, so always verify current upload specifications on the relevant city portal before submitting.
- Boston:
BOSTON_[EventName]_SitePlan_[YYYY-MM-DD].png, landscape orientation, minimum 150 DPI, with the legend attached as a separate PNG. - San Francisco:
SF_[EventName]_SitePlan_[YYYY-MM-DD].png, portrait or landscape per DPW portal guidance, graphic scale bar visible, legend attached separately. - New York City:
NYC_[EventName]_SitePlan_[YYYY-MM-DD].png, north arrow and title block visible at print size, legend attached separately. - Chicago:
CHI_[EventName]_SitePlan_[YYYY-MM-DD].png, all layer labels visible, legend generated and attached as a separate PNG. - Los Angeles:
LA_[EventName]_SitePlan_[YYYY-MM-DD].png, all dimensions labeled on the plan face, scale bar visible, legend attached separately. - Austin:
AUS_[EventName]_SitePlan_[YYYY-MM-DD].png, high-resolution PNG with north arrow and scale bar visible, legend attached separately. - Philadelphia:
PHL_[EventName]_SitePlan_[YYYY-MM-DD].png, with the Permit Navigator guide attached alongside the PNG export. - Seattle:
SEA_[EventName]_SitePlan_[YYYY-MM-DD].png, scale bar clearly visible at intended print size, legend attached separately.
If a portal requires PDF format, export the PNG from OnePlan first and convert using any standard PDF printer at the same DPI. Keep the original resolution during conversion, because reviewers need to zoom in to verify dimensions.
Reusing Approved Maps and Tracking New Approvals
Once a city reviewer approves your public market permit approval map, save the approved plan as a reusable template inside OnePlan. Import the approved PNG back into OnePlan, scale it onto the map, and use it as the base layer for next year’s application. Your starting point for every future submission becomes an already-approved layout instead of a blank canvas.
Markets that run annually, such as farmers markets, seasonal food markets, and holiday markets, benefit most from this workflow because the site footprint rarely changes dramatically year to year. Update vendor stall assignments, adjust crowd areas for new capacity targets, and export again with the current date in the file name. Reviewers then see a submission that reflects a proven, previously approved layout with only the changes that actually occurred.
Cities including Cambridge, Massachusetts now offer interactive permit dashboards that let organizers search permits by address, view permit locations on a map, and filter by permit type. As more U.S. cities follow this model, tracking the status of your submission will become easier, but the quality of your initial map remains the single biggest factor in whether you pass first review.
Frequently Asked Questions
Do I still need CAD software to produce a public market permit approval map?
You do not need CAD software to produce a public market permit approval map. CAD tools were built for engineers and technical drafters, carry a steep learning curve, and are expensive for most market organizers. Reviewers actually require a to-scale, dimensioned site plan with the correct layers, not a file produced in any specific software.
OnePlan produces exactly that: a map-based, to-scale plan where every vendor stall, fire lane, and ingress or egress route is accurately placed and dimensioned, then exported as a high-resolution PNG that meets the upload specifications of every portal in this guide. If you already have CAD-derived files, convert them to PNG and import them into OnePlan as a base layer to build on.
What if my city is not listed in this guide?
The eight cities above cover the largest and most active U.S. public-market permitting environments, but the universal checklist in the “What Your Submission Map Must Show” section applies to almost every U.S. municipality. Start with that checklist, then visit your city’s special-events or licenses-and-inspections department website to confirm any additional local requirements.
Most cities publish site plan examples or minimum-standard guides. Build your map in OnePlan using the universal layer set, then add any city-specific elements before export.
How does OnePlan handle the 20-foot emergency access lane requirement?
OnePlan’s area and perimeter calculator lets you draw the emergency access lane as a polygon and instantly confirm its width in feet. If the lane is narrower than 20 feet, you see it immediately on the to-scale map and can adjust vendor stall placement before export. This approach removes the most common fire-access rejection reason, which is a lane that looks wide enough on a non-scaled screenshot but fails the dimension check in review.
Can I use OnePlan for a market that runs every week, not just once a year?
You can use OnePlan for weekly markets as well as annual events. Save your approved layout as a reusable template and open it for each new permit cycle. Update the date in the title block, adjust any stall assignments or crowd areas that have changed, and export a fresh PNG.
Recurring markets benefit most from OnePlan because the base plan is already approved, so you only document changes instead of rebuilding from scratch every time.
What crowd capacity information should I include on my permit map?
Show crowd areas as dimensioned polygons on your map. OnePlan’s standing crowd capacity calculator lets you outline any crowd area and instantly calculate how many people that space can safely hold based on your chosen density setting. Include the calculated capacity figure as a label on the crowd area polygon in your exported map.
Always follow your local authority’s specific density requirements and consult the relevant fire, police, and licensing bodies for your jurisdiction, because requirements vary by city and event type. For arrival and exit flow planning, use OnePlan’s free arrival calculator and exit calculator to estimate queue lengths and exit capacity before your event day.
Plan Your Next Public Market with OnePlan
Every public market organizer filing a permit in the next 30 days faces the same problem: scattered municipal portals, inconsistent layer requirements, and static files built in PowerPoint or Google Maps that fail first review because they are not to scale and do not show the layers reviewers actually check. OnePlan solves all of this in one place.
Your base layer is a live satellite map. Every vendor stall, fire lane, hydrant clearance zone, and ingress or egress route you place on it stays accurately to scale as you zoom. The area calculator confirms your emergency access lane is a full 20 feet wide. The standing crowd capacity calculator dimensions your crowd areas. You then export as a high-resolution PNG with a title block and legend, name the file to match your city’s convention, and upload directly to the portal.
Your first event is free, up to 25 objects, so you can start placing objects on your map right now with no payment details required.
