Public Health Seattle and King County Temporary Food Service Business Permit (Farmers Market)

The county-issued local instance of the statewide temporary food permit, required for any vendor who handles open food, offers samples, cooks, or makes retail food sales at a Seattle-area farmers market. Every vendor obtains their own permit; the market organizer holds separate operational permits that do not cover individual booths. A farmer selling only pre-packaged produce may qualify for a permit exemption under WAC 246-215, but must apply to Public Health at least 14 days before the first market and receive written approval before assuming exempt status.

Issued by: Public Health Seattle and King County, Environmental Health Food Protection Program
Fee: Tiered by food complexity: a single-season permit runs $126 (Minimal, pre-packaged), $315 (Moderate, open food or sampling), or $441 (Complex, cooking raw animal products); unlimited annual permits are $252, $882, and $1,008. Multi-event Moderate and Complex permits also require a $126 Certified Booth Operator card
Renewal: Annual (calendar year); single-event permits cover one full market season
Processing: Apply at least 2 weeks before the first market date; approval communicated by Public Health after review

Seattle Business License Tax Certificate

Every business doing business in Seattle must hold this certificate, including a vendor based in another city or county who sells at a Seattle farmers market. An outside-Seattle vendor is only exempt if their total Seattle gross receipts for the year are $4,000 or less and they maintain no Seattle place of business. Register and file through the FileLocal portal. Applies to all five vendor models.

Issued by: City of Seattle, Office of City Finance
Fee: $73 a year at the lowest 2026 tier (under $20,000 in Seattle revenue), $147 from $20,000 to $499,999, scaling up from there; half-price if you open July 1 or later. Vendors with $4,000 or less in Seattle gross receipts and no Seattle location are exempt
Renewal: Annual (expires December 31)
Processing: Minutes to 2 to 3 business days online via FileLocal

Seattle Business and Occupation (B&O) Tax

Seattle's B&O tax is a gross-receipts tax on the privilege of doing business in the city, separate from and on top of the state B&O tax. The 2026 no-tax threshold of $2 million covers nearly every market vendor, but the annual return and the business license fee are still owed. Food and craft sales report under the retailing classification. A vendor based outside Seattle still has nexus from selling at Seattle markets and must file.

Issued by: City of Seattle, Office of City Finance
Fee: No tax owed under $2,000,000 in annual Seattle gross receipts (threshold raised effective January 1, 2026); above that, 0.342% under retailing after a $2,000,000 standard deduction. The return is still required even when no tax is due
Renewal: Annual return (due April 30 for annual filers), filed via FileLocal
Processing: Self-assessed; no separate processing

SDOT Street Use Vending Permit (only for vending in the public right-of-way)

Required only when a vendor independently sets up a cart or stand in a Seattle public sidewalk or street right-of-way. Vendors renting a stall at an established farmers market on private property or in a city park do not need this permit; the market organizer holds the authorization for that site. Applies conditionally to any vendor model that independently occupies public right-of-way.

Issued by: Seattle Department of Transportation (SDOT), Street Use
Fee: About $1,025 to issue a year-round site-specific permit ($597 to renew); a seasonal or single-event permit is $81. A Downtown Activation Plan fee waiver ran through December 31, 2025, so confirm current 2026 amounts with SDOT
Renewal: Annual (year-round permits) or seasonal
Processing: Allow several weeks for site review via the Seattle Services Portal

City of Seattle Weights and Measures Device Registration (only if you sell by weight)

Any vendor who sells by weight at a Seattle market must register their commercial scale with the City of Seattle sealer rather than the state WSDA program. Seattle is one of only two Washington cities (with Spokane) that operates its own weights-and-measures program under RCW 19.94 and SMC Chapter 7.04. Registering through the DOR state endorsement does not satisfy this requirement inside Seattle city limits.

Issued by: City of Seattle, Finance and Administrative Services, Consumer Protection (City Sealer)
Fee: Set by the City of Seattle sealer and capped at the state rate of $10 a year per small scale; confirm the current amount with Consumer Protection at (206) 386-1267
Renewal: Annual
Processing: Contact the City Sealer to schedule a sealing inspection

Seattle Fire Department LPG and Open Flame Permit, Annual (Code 8206-FVH)

Required for any non-mobile food booth at a Seattle market that uses propane, compressed natural gas, charcoal, or any open flame for cooking or heating. This is a per-vendor permit; the market organizer holds a separate permit only for venue-level propane heating units, which does not cover individual vendor cooking. A vendor attending only one event per year can use the single-event 8207-VH permit instead; two or more events makes the $408 annual permit the cheaper option.

Issued by: Seattle Fire Department, Fire Prevention Division
Fee: $408 a year; SFD requires a field inspection before issuing the permit
Renewal: Annual
Processing: Submit the application and payment; SFD schedules a field inspection before issuing the permit. Allow 2 to 4 weeks

Seattle Fire Department LPG and Open Flame Permit, Single Event (Code 8207-VH)

The single-event alternative to the annual 8206-FVH permit, suited to a hot-food vendor attending only one Seattle market or event per year with propane or open flame. Two events at $273 each ($546 total) costs more than the $408 annual permit, so a vendor working two or more events in Seattle should apply for the annual permit instead.

Issued by: Seattle Fire Department, Fire Prevention Division
Fee: $273 per event, with a 50% late fee for applications received fewer than 10 business days before the event
Renewal: Per event
Processing: Submit at least 10 business days before the event; applications received 3 or fewer business days before the event may not be processed in time

Seattle-specific things to watch for

1The county, not the city, runs the food permit. There is no Seattle city health department for farmers market vendors. Public Health Seattle and King County, a county agency, issues all temporary food service business permits for markets anywhere in King County, including inside Seattle city limits. Do not look for a Seattle city food permit; it does not exist for market vendors.

2The farmers market organizer's permits do not cover individual vendor booths. The organizer holds a tiered operational permit for the market itself and may hold a 2500-LPG permit for shared propane heating units. Neither covers a vendor who handles open food or cooks on site. Every food vendor must obtain their own King County temporary food permit.

3Outside-Seattle vendors still need the Seattle business license. The city license is triggered by where you do business, not where you are based. A vendor from Tacoma, Bellevue, or rural King County selling at a Seattle market must hold a Seattle Business License Tax Certificate unless total annual Seattle gross receipts are $4,000 or less (effective 2026 threshold). Most market regulars exceed that and need the license.

4Seattle operates its own scale sealer. Washington has two cities with independent weights-and-measures programs: Seattle and Spokane. A vendor selling by weight at a Seattle market must register their commercial scale with the City of Seattle Consumer Protection office, not through the DOR state endorsement. Registering with the state does not satisfy the city requirement, and the city sealer must inspect and seal the device.

5The Certified Booth Operator card gates the Moderate and Complex multi-event health permits. King County requires a CBO card before issuing a Moderate or Complex unlimited or 5-event permit for a hot-food vendor. The course runs monthly and costs $126 for a two-year card. A vendor planning a full market season with open or cooked food needs to complete the course before the permit application, making the CBO course the actual long-lead item at 4 to 6 weeks.

How long does it take?

A craft or produce vendor can sell within 1 to 3 weeks, limited mainly by state UBI processing and the nearly instant Seattle business license via FileLocal. A cottage food vendor adds the county health permit, which needs at least 2 weeks before the first market, putting the total at 3 to 6 weeks. A hot-food vendor cooking on site needs the longest runway: the King County Moderate or Complex unlimited permit requires a Certified Booth Operator card first (the course runs monthly, so allow 4 to 6 weeks just to get a seat), and the Seattle Fire annual LPG permit needs a field inspection at 2 to 4 weeks, making 6 to 10 weeks realistic from scratch.

Frequently asked questions

Do I need a permit to sell at a Seattle farmers market?

Craft vendors handling no food need only the Seattle Business License Tax Certificate ($73 at the lowest tier in 2026). Any vendor who handles open food, offers samples, or cooks on site also needs a King County Temporary Food Service Business Permit, which runs $126 to $441 for a single-season permit depending on food complexity. Hot-food vendors cooking with propane or open flame additionally need a Seattle Fire Department LPG permit ($273 for a single event or $408 for the year). A farmer selling only pre-packaged produce may qualify for a county health permit exemption but must apply for it in writing at least 14 days before the first market.

Do I need a Seattle business license to sell at a farmers market if I live outside Seattle?

Yes, in most cases. Selling at a Seattle market counts as doing business in Seattle, so a vendor needs the Seattle Business License Tax Certificate regardless of where they live or are based. The only 2026 exception is if total annual gross receipts earned inside Seattle are $4,000 or less and the vendor maintains no place of business in the city. Most vendors who attend more than a handful of markets exceed that threshold and need the license.

Does the farmers market organizer's permit cover my food booth?

No. The market organizer holds their own operational permits and may hold a blanket heating permit for shared propane units, but those documents do not extend to individual vendor booths. Every vendor who handles open food, offers samples, or cooks on site must obtain their own King County Temporary Food Service Business Permit.

I only sell jam and baked goods at Seattle markets. Do I need a health permit?

Possibly not, but you must confirm it before selling. If your cottage food products are shelf-stable and you are not offering open samples, you may qualify for a Public Health permit exemption under WAC 246-215. The exemption is not automatic: you must submit an exemption application to Public Health Seattle and King County at least 14 days before your first market and receive written approval. If you offer taste samples or your goods require temperature control, a Minimal-tier permit is required ($126 single-event or $252 unlimited).
