Local business is governed locally: the rules that matter live at city hall, the county health department and your state’s licensing boards, and they differ from one town to the next in ways no national website can promise. What follows is the map, and the method for reading your own town’s version of it.
Call the city clerk. Say: “I’m opening a ___ at ___. What do I need?” They will list it — license, zoning, inspections, fees — usually helpfully, because half their job is this call. Take the list to your SBDC advisor, who reviews it free. Do this before money moves; inspectors met early are guides, and inspectors met after you’ve built are graders.
The city or county business license ($50–150 a year, typically). A seller’s permit and sales-tax collection if you sell goods — and, in a growing number of states, certain services too. A zoning check — home businesses are broadly fine until customers start parking outside. A DBA filing if the sign says something other than the LLC’s legal name.
The health department rules everything edible: permits, plan review before you build or buy, a certified food manager, commissary kitchens for mobile units, fire suppression over hoods. And its merciful side door: most states’ cottage food laws let baked and shelf-stable goods start from a home kitchen with a simple registration — the cheapest legitimate entry into food that exists, and the right first step for almost everyone who dreams about a bakery.
Trades: contractor licenses above your state’s dollar cap; a pesticide applicator license the day you spray anything; the federal RRP lead-paint certification (~$300) for renovation work on pre-1978 homes — genuinely enforced, genuinely fined. Personal care: cosmetology and barber licensing per person plus shop inspections, which is why booth rental inside an existing shop is the low-risk entry. Any storefront: certificate of occupancy, fire inspection, ADA accessibility, and a sign permit before the sign goes up — cities fine that one constantly because it’s constantly skipped.
The pattern worth internalizing: permits aren’t the obstacle course they look like from outside. They’re a to-do list someone else already wrote, in order, with phone numbers. Businesses don’t fail from permits; they fail from discovering permits late.
