Vendor Essentials Guide: permits, insurance, electricity
There are a number of event details that are ubiquitous and vary per event that Canopy Season does not track in our event listings. The reason why I chose not to include licensing, permits, insurance, electricity, and weight requirements is that these items are standard across the vending landscape. Once you have set up or obtained each, you no longer need to worry about what you need to submit with an application.
The Shortlist compares booth fees, dates, deadlines, and estimated attendance. What it can't compare is the operational half of the decision — the stuff that turns a $450 show into a $900 show, or a good sales day into a $300 loss because your permit wasn't in your name. None of what follows is legal advice, and none of it is exhaustive. It's the honest briefing an experienced organizer would give you if you asked the right questions early enough.
Permits and licenses
There are usually three layers, and they don't overlap the way you'd hope. The city where the event happens may require a temporary or itinerant vendor license. The state wants you registered to collect sales tax. And the event itself may need permits — health, fire marshal, tent — that either the organizer holds or you do.
Sales tax is the layer vendors miss most. If you're selling in a state where you're not already registered, most of them offer a temporary permit for exactly this situation: California issues a temporary seller's permit through CDTFA, Colorado runs a special event license, Washington state requires that vendors obtain a master state business license then add endorsements for each city where you plan to vend. They're generally free or nominal and you can apply online, but give yourself two weeks — some states still mail the certificate. Remittance timing varies wildly: some want the return within 15 to 30 days of the event, others fold it into your regular quarterly filing. Five states won't ask at all, since they have no statewide sales tax.
Established fairs — state fairs, big juried festivals, certified farmers markets — often hold a blanket permit that covers you as a participating vendor. Most craft markets and street fairs do not, and the application language can be genuinely ambiguous about it.
So ask this before you apply, in writing: Which permits does the event hold, and which am I expected to hold in my own name? Do you need copies in advance, and by what date? An organizer who can answer that in one email is an organizer worth vending with.
Weights
Every outdoor event will require weights. This is a non-negotiable requirement and the most important safety measure you need to take to protect your inventory as well as other vendors and event attendees.
The standard weight required is 25 pounds per tent leg.
Some events require a minimum of 20lbs, some 30lbs. Don't skimp and don't take it for granted. Insurance won't be enough to save your ass if someone gets injured as a consequence of your tent taking flight during a storm because you didn't follow rules or didn't secure your weights to your tent legs.
Insurance
Nearly every event above the church-basement tier now requires general liability coverage at $1 million per occurrence and $2 million aggregate. That number has become standard enough that it's worth treating as the baseline for what you carry, not the exception.
The organizer's policy protects the organizer. If a customer trips over your cord or your display tips onto a stroller, you're a separate business and their attorney will name you separately. That's the whole reason the requirement exists.
If you sell anything consumable or wearable — food, candles, soap, lotions, jewelry, anything a kid might put in their mouth — you also want product liability. It's often bundled as products-completed operations coverage, but not always, and some cheap policies exclude it outright. Read that line specifically.
Cost breaks into two tiers. An annual policy for a typical craft or food vendor generally runs $350 to $600. Per-event riders run about $60 to $120. The math is simple: if you're doing five or more shows a year, the annual policy wins, and it wins harder because you can produce a certificate the same day instead of waiting on a carrier every time.
That certificate — the COI — is the actual deliverable. The organizer needs to be listed as an additional insured, spelled with their exact legal entity name, which is frequently not the name of the event. Some municipal events also require the city and the property owner named. Get the exact naming string from the organizer in writing, then give your carrier a week. A COI issued to the wrong entity is the same as no COI at the check-in table.
TIP: The smartest decision you can make is to obtain liability insurance for your business that covers selling at markets. Also ask about protecting your inventory at the event and at your warehouse or storage facility (this includes your home).
Electricity
"Electricity included" is the most elastic phrase in this entire business. It can mean a dedicated 20-amp circuit at your back tent leg. It can also mean one 15-amp household circuit daisy-chained down eight booths, with you at the far end.
The vocabulary that matters is amperage, and the math is one line: watts divided by 120 equals amps. A 1,500-watt griddle draws 12.5 amps by itself. Because anything running longer than three hours counts as a continuous load, you plan against 80% of the circuit — roughly 1,440 usable watts on a 15A circuit, 1,920 on a 20A. Two crock pots and a card reader will trip a 15A circuit before lunch. Add up the wattage on the nameplate of every heating device you're bringing and hand the organizer that number, not a vague "I need power."
Heat is the whole problem. Candle warmers, hot plates, panini presses, espresso, wax melters, hot glue. LED string lights, a laptop, a phone charger, and a card reader together draw less than a single lamp. If you have nothing with a heating element, you probably don't need to pay the power fee at all.
Outdoor circuits are required to be GFCI protected, which is a safety win and an operational headache. GFCIs nuisance-trip on damp cords, worn insulation, and motor startup — a neighbor's cooler compressor kicking on can take your booth down with it. Test your setup in the morning while there's still time to move, and carry a spare cord.
Generators are increasingly restricted. Many events ban them outright; others allow inverter models only, under a decibel cap, with fuel storage prohibited inside the booth footprint and refueling permitted only when the unit is cool. Conventional open-frame generators are loud enough to be a neighbor complaint by 10am. Ask about quiet hours and whether a fire extinguisher is required.
Bring your own cords regardless of what's promised. Heavy-gauge outdoor-rated, 12-gauge for any run over 50 feet — a thin indoor cord at length drops voltage, runs hot, and is the single most common thing a fire marshal will pull you up on. Tape every run down or ramp it. Trip hazards are where your liability policy earns its premium.
TIP: If your electricity needs are minimal — running a Square Stand with iPad or similar checkout device, lighting, phone, or a small fan — I'd recommend a portable power station like Jackery or Ecoflow. I own two Ecoflow products: a Delta 2 and a River 3. The Delta I use for Christmas events where I need to power multiple lights and my checkout station. My daily driver is the River 3 (which I love). I carry one of these to every event so I will never be without power.
Load-in and load-out
Nobody quotes you the two hours on either end, but they're the hours that decide whether you sell well on day two.
Access windows are usually staggered, and the rule at most urban events is vehicle-in, unload, park out, then set up. That can mean twenty minutes at the curb before you're moved along, so stage your load in the order you need it. If the site is grass, gravel, or has any distance from parking, a dolly with pneumatic tires is not optional — hard plastic wheels stop dead in turf.
Ask about stakes early. Many urban and paved events forbid them entirely, because of asphalt, irrigation lines, and buried utilities. That makes weights mandatory: 40 pounds per leg is the common minimum, and exposed or waterfront sites justify more. Plan on carrying that weight from your car twice.
Teardown is where the pressure lands. Thirty-minute windows are normal at street fairs, and vehicles usually can't return until the street clears of the public, so you're hand-carrying to a staging point first. Pack the truck in reverse order of how you'll need it.
Weather contingency
If the show cancels day-of, most events do not refund. The booth fee is generally treated as earned when the space was assigned, and the application language will say so if you look for it. Read that clause before you send money, especially for a spring or fall date.
"Rain or shine" is a promise the event will run — it isn't a refund policy, and it doesn't stop an organizer from closing for lightning or wind. Sustained winds around 25 to 30 mph are the typical trigger for a shutdown, and that's about where most pop-up canopies are rated fully weighted. Unweighted, a canopy becomes airborne well below that.
Sidewalls are the trap. They make a tent comfortable and they also make it a sail — in real wind you take them off, not put them on. Carry more weight than you think you need, ratchet straps for the frame, lidded bins so a gust doesn't redistribute your inventory across the parking lot, and a tarp big enough to cover the table when you walk away.

We publish what we can verify and we flag what we can't. Ask the organizer to defend the rest, in writing, before you send a check — and keep a running vendor-essentials binder for markets you return to, so year two takes an afternoon instead of a week.
If you got here another way, your saved events are on The Shortlist.
