Idaho's cottage food framework is built on one idea: if your product is safe at room temperature, you can sell it from your home kitchen. Here's how the rules work and what they mean for your business.
In Idaho, cottage foods are defined as non-Time/Temperature Control for Safety (non-TCS) foods — products that don't require refrigeration to stay safe. These are the only foods you can sell under the cottage food framework, and they're the products that qualify for Idaho's no-permit, no-inspection, no-sales-cap rules.
Whether a food is shelf-stable comes down to science. Idaho uses two measurable thresholds — pH and water activity — to determine if a product can safely sit at room temperature. If your food meets either threshold, it's generally considered non-TCS and eligible for cottage food sales.
pH measures how acidic a food is on a scale from 0 (most acidic) to 14 (most alkaline). Water is neutral at 7.0. Foods with a pH below 4.6 are acidic enough to prevent the growth of most dangerous bacteria, including Clostridium botulinum. Most fruits, vinegars, and full-sugar jams and jellies fall below this threshold naturally.
Water activity measures how much moisture in a food is available for bacteria to use. Pure water has an aw of 1.0. Foods below 0.85 are too dry for most pathogens to thrive. Baked goods, dried fruits, hard candies, granola, and jerky-style products typically fall below this threshold. Crackers and cookies are usually well under 0.6.
If you're unsure whether your recipe qualifies as non-TCS, Idaho provides a clear path forward. You can submit a sample of your product to a private laboratory for pH and water activity testing. Once you have results showing pH below 4.6 or aw below 0.85, share them with your local Public Health District using the Cottage Food Risk Assessment Form. An Environmental Health Specialist will review and sign off if your product meets the criteria.
This testing route is especially useful for products like fruit butters, fruit leathers, pumpkin pies, and other borderline items that may or may not require refrigeration depending on the recipe.
Unlike most states, Idaho does not impose any annual gross sales cap on cottage food operations. You can earn unlimited revenue from your home kitchen — as long as you sell only non-TCS foods directly to consumers within Idaho.
This makes Idaho one of the most permissive states in the nation for home food sellers. There are no tiers, no thresholds, and no point at which you're required to transition to a commercial kitchen based on sales volume alone.
That said, you still need to comply with Idaho tax requirements. All cottage food sales are subject to the state's 6% sales tax, and you'll need an Idaho seller's permit to collect and remit it. Your income is also subject to Idaho's flat 5.3% state income tax and federal self-employment tax. See the Licenses & Permits guide for details.
Idaho allows cottage food sales at any venue — as long as every sale is direct to the end consumer and the buyer is located within Idaho. Here's a breakdown of every channel and its status under Idaho Code § 39-1608.
Sell directly to consumers at any Idaho farmers market. Some markets may independently require the Cottage Food Risk Assessment Form or proof of food safety training — check with the market organizer.
Set up a stand on your property or at a permitted location and sell your cottage foods to walk-up customers.
Festivals, fairs, church events, school fundraisers, and community gatherings are all approved venues.
Customers can pick up orders directly from your home. You can also deliver to local buyers yourself.
Sell through your own website, social media, or a marketplace like SellFood. Buyer's shipping address must be within Idaho.
You can ship cottage foods to Idaho addresses via mail or delivery service. No out-of-state shipments.
Selling to restaurants, grocery stores, or other retailers is not permitted. Any third-party distribution reclassifies you as a regulated food establishment.
Cottage food may not be shipped or sold to consumers outside of Idaho. If you sell outside the state, FDA regulations apply and you'd need commercial licensing.
Idaho does not require home kitchen inspections for cottage food producers, and there are no specific storage regulations in the Idaho Food Code for cottage food operations. However, safe food handling is still your responsibility — and good practices protect both your customers and your business.
Keep your kitchen clean. While not inspected, your home kitchen should be maintained to the same standard you'd expect at a bakery or food shop. Sanitize surfaces, clean equipment, and wash hands frequently during production.
Store finished products properly. Shelf-stable doesn't mean indestructible. Keep products in clean, sealed containers away from direct sunlight, heat, and moisture. Cool, dry, dark storage extends shelf life.
Manage pets carefully. Idaho allows pets in the home where cottage food is produced, but the state advises caution. Keep animals out of the kitchen during production and clean thoroughly afterward.
Test your water if private. If your home uses a private well rather than municipal water, the Idaho Department of Health and Welfare recommends testing it every three months for bacteria. More information at IDHW Water Safety.
Consider food safety training. While not required, completing the free Idaho Food Safety Exam gives you a certificate valid for five years and demonstrates to customers that you take safety seriously.
Tip: Even though Idaho doesn't require the Cottage Food Risk Assessment Form, completing it and having your local Public Health District sign off is a smart move. Many farmers markets require it, and it gives you documented confirmation that your products are approved cottage foods. The form is free — available at foodsafety.idaho.gov.
