If you are starting a home-based business, you will need to be aware of any restrictions on the operation of your business, and any licenses or permits that will be required—whether you are baking pies, washing cars, babysitting children, grooming dogs, or providing counseling services. Some of the common sources and types of these restrictions, licenses, and permits are: (1) local zoning laws—including for signs for your business; (2) restrictions from your HOA (homeowners’ association), property deed, or residential lease agreement; (3) tax permit (sales and use tax) or resale/reseller’s certificate; (4) occupational license; (5) city or county business license; and (6) health and safety permit.

In Montana (MT), starting a home-based business requires compliance with various regulations. Local zoning laws may restrict the type of business activities you can conduct in a residential area, including the use and placement of signs. It's important to check with your local planning department for any zoning restrictions. If your home is part of a homeowners' association (HOA), you'll need to review the HOA's covenants, conditions, and restrictions (CC&Rs) for any prohibitions or limitations on running a business from your home. Additionally, your property deed or residential lease agreement may have clauses that affect your ability to operate a business. For tax purposes, if you're selling goods, you may need a tax permit for sales and use tax or a resale/reseller's certificate from the Montana Department of Revenue. Depending on the nature of your business, you might require an occupational license, which is profession-specific and regulated by various state boards. A city or county business license may also be necessary, and this can be obtained through your local city or county clerk's office. Lastly, if your business involves food preparation, childcare, or other activities that impact health and safety, you may need to obtain a health and safety permit from the appropriate state or local health department. It's advisable to consult with an attorney to ensure that all legal requirements are met for your home-based business.
