How to Start a Homemade Food (Cottage Food) Business in Hawaii: DOH Permit Exemption Since August 24, 2025, pH 4.2 and Aw 0.88 Limits, Required Label

If you make jams, pickles, dry mixes, cookies, or other shelf-stable products in your home kitchen, Hawaii's cottage food rule may let you sell them without a Department of Health (DOH) food establishment permit. The rule took effect August 24, 2025, under Hawaii Administrative Rules (HAR) 11-50-2, 11-50-3(c), and 11-50-35(c). The exemption is narrow. It covers only certain products, it sets measurable limits, and it comes with conditions, a required label, and continued DOH inspection authority.

One point to understand before you search for a cottage food license in Hawaii: the rule works as an exemption from the food establishment permit. It does not create a separate cottage food permit you apply for. The one universal state registration you will need is the one-time $20 General Excise Tax (GET) license. This guide walks through the process in the order you should complete it.

What the 2025 Rule Covers

Under HAR 11-50, a producer who makes or packages only homemade food products in a home kitchen is exempt from the food establishment permit. You are still subject to DOH inspection, so the exemption is not an exit from state oversight.

The term “homemade food products” has a specific meaning. It includes non-TCS foods made in a home kitchen, but it excludes dried meat or seafood. It also includes pickled, fermented, or acidified plant foods (not melons) that test at pH 4.2 or lower, or that have a water activity (Aw) below 0.88. TCS stands for time and temperature control for safety, which describes foods that need temperature control to limit bacterial growth. Water activity measures how much free water is available for microbes to use, on a scale from 0 to 1.0.

May fit the exemption (confirm each product)	Does not fit the exemption
Non-TCS baked goods such as cookies and many breads, if they contain no TCS fillings or toppings	Cheese, meat pies, and sushi, which still need a DOH permit and a permitted kitchen
Dry mixes, spice blends, and other non-TCS dry goods	Dried meat or seafood, which is excluded
Jams and jellies, if tested and documented	Melons, which are excluded from the pickled and acidified category
Pickles, fermented vegetables, and acidified plant foods that test at pH 4.2 or lower, or Aw below 0.88	Acidified or pickled plant foods that do not meet either limit
Salsa, only if you can keep it at or below 41°F at all times	Salsa with cut tomatoes kept above 41°F

Materials and Equipment You Need

• A calibrated pH meter for pickled, fermented, and acidified products
• A water activity meter for any product you claim meets the 0.88 Aw limit
• Written recipes with exact ingredient weights and process steps
• A batch log recording dates, test results, lot numbers, and sales
• A handwashing sink with soap available during preparation
• A food safety certification (confirm which certifications DOH accepts)
• Finished labels with the required text (see Step 6)
• A Hawaii General Excise Tax license ($20 one time)
• A kitchen scale, measuring tools, and clean food-grade containers and packaging
• A bookkeeping system that tracks gross receipts, since GET is measured on them

Step-by-Step: Starting Your Cottage Food Business in Hawaii

Step 1: Sort Every Product Into Eligible or Ineligible

List every product you plan to sell. For each one, ask three questions. Is it non-TCS? Is it free of dried meat or seafood? If it is a pickled, fermented, or acidified plant food, does it test at pH 4.2 or lower, or at Aw below 0.88? Any product that fails stays out of your cottage food line. Products that need refrigeration or temperature control, such as cheese, meat pies, or sushi, require a DOH permit and a permitted kitchen, so the exemption will not cover them. Keep that list in your batch log so you can show how each product was classified.

Step 2: Test Each Product Before Sale

Do not rely on a recipe's ingredient list alone to prove that a product reaches pH 4.2 or lower or Aw below 0.88. Measure each product with a calibrated meter and record the reading next to the batch date. Retest whenever you change an ingredient, switch produce suppliers, or alter a process step, because small changes can shift acidity. Ask DOH which testing methods and records it expects before you rely on your own procedure.

Step 3: Obtain Your Hawaii General Excise Tax License

Hawaii has no general purpose state business license, but the Department of Commerce and Consumer Affairs (DCCA) Business Action Center states that every person doing business in Hawaii must hold a GET license from the Department of Taxation. The fee is $20, paid once. You can apply on Form BB-1 or through Hawaii Tax Online at tax.hawaii.gov/get/. Processing is immediate in person, 5 to 7 business days through Hawaii Tax Online, and 4 to 6 weeks by mail. The license stays active until you close it, surrender it, or it is revoked.

The GET is a tax on your gross receipts, not a separate charge on the customer's bill. Hawaii has no sales tax. The state rate is 4.0 percent, plus a 0.5 percent county surcharge, for a 4.5 percent rate on retail sales. Wholesaling carries a 0.5 percent rate. If a sale to a store for resale qualifies as wholesaling, the lower rate may apply, but confirm that treatment with the Department of Taxation. Every license holder must file periodic and annual returns, even in a period with no income. If you visibly pass the tax on to customers, the maximum pass-on rate is 4.7120 percent.

Step 4: Choose a Business Name and Structure

You can operate as a sole proprietor under your own name without forming an entity. If you sell under a different name, register a trade name with the Business Registration Division (BREG) on Form T-1. The fee is $50.00, plus a $1.00 State Archives preservation fee. A registration is valid for five years, and the Department does not send renewal notices, so put the renewal date on your calendar. Trade name registration is a filing, not a license.

If you form a limited liability company, file Articles of Organization (Form LLC-1) through Hawaii Business Express at hbe.dcca.hawaii.gov. The filing fee is $50. The name must include “Limited Liability Company,” “L.L.C.,” or “LLC.” Your registered agent must be an individual or entity authorized to transact business in Hawaii and physically present in the state, and an LLC cannot serve as its own registered agent. Check name availability for free using the BREG search at hbe.dcca.hawaii.gov/search-and-buy. If you want to hold a name while you finish paperwork, a name reservation costs $10 and lasts 120 days. An LLC also files an annual report with a $12.50 fee. It is due by the end of the calendar quarter that matches your registration quarter, and no report is required in the year you register.

Step 5: Prepare Your Home Kitchen

The rule requires a handwashing sink with soap during food preparation. Set up that sink so it is usable while you work, not only as storage space. Keep your production area separate from anything that would contaminate food, and keep your records current, since an inspector may ask for them. Hawaii has four counties (Honolulu, Hawaii, Maui, and Kauai) and no incorporated cities, so your county sets the local rules that apply to running a business from a residence. Check with your county planning department about home-based business and zoning requirements before you begin production.

Step 6: Write a Compliant Label

Every product sold under the exemption must carry a label that includes the following:

• The statement “Made in a home kitchen not routinely inspected by the Department of Health”
• The common name of the product
• All ingredients, listed by weight
• Major allergens, including sesame
• Your name and contact information

Print the statement exactly as written. Do not shorten it or replace it with wording such as “made in a commercial kitchen.” Check your allergen list against every ingredient, including seasonings, flavorings, and packaging inserts that may contain sesame or another major allergen. Do not make health, shelf-life, or nutritional claims on the label unless you can support them.

Step 7: Choose Your Sales Channels

The rule allows several ways to sell. You may sell directly in person, by phone, or online. You may sell through an agent or a third party, such as a retail store, and DOH states that wholesale is allowed. You may also deliver products by mail or shipping. Each channel still requires an eligible product, a compliant label, and a GET license. Shipping a product that fails the pH or Aw limit does not become legal because the buyer is out of state, and any sale into another state may bring that state's rules into play. Confirm those rules before you ship beyond Hawaii.

Step 8: Keep Records and Calendar Your Filings

Keep batch logs, pH and Aw readings, your food safety certification, labels, and sales records together. Your GET return periods and annual returns depend on accurate receipts. If you form an LLC, calendar the annual report deadline for the end of your registration quarter each year. If you use a trade name, calendar the five-year re-registration. If you hire employees, you must follow the Prepaid Health Care Act, so talk with a CPA or employment professional before your first hire.

Common Mistakes to Avoid

• Assuming any homemade food qualifies. Cheese, meat pies, and sushi still need a DOH permit and a permitted kitchen.
• Treating a recipe as proof of acidity. Test each product with a calibrated meter and retest when something changes.
• Skipping the GET license. The $20 license is required even if your first sales are small.
• Using incomplete labels. Missing sesame, an incorrect ingredient order, or altered required wording can cause problems at inspection.
• Selling salsa with cut tomatoes above 41°F. That product must stay at or below 41°F, so it cannot be handled like a shelf product.
• Confusing a trade name with a license. Form T-1 registers a name. It does not authorize you to sell food.
• Ignoring county rules. A home kitchen that complies with DOH may still face local zoning or home-business limits.
• Missing filing deadlines. An LLC annual report or a five-year trade name renewal lapses if you do not track it.

Expected Results

If your products qualify, your labels are complete, and your GET license is active, the exemption may allow you to sell eligible products without a DOH food establishment permit. Results depend on your product mix, your testing discipline, your pricing, and your local market, and no outcome is guaranteed. The exemption does not mean DOH will never inspect your kitchen, and it does not make an improperly tested product safe. Treat the rule as a set of conditions to meet every time you produce and sell, not as a one-time approval.
