Do home-based businesses need a business license?

Usually yes. Running a business from home does not exempt it from licensing; it often adds a requirement instead. Most cities and counties expect home businesses to hold the same general business registration as any other, and many also require a home occupation permit confirming the use fits residential zoning. State activity licenses apply exactly as they would from an office.

The home occupation layer

Zoning is the piece unique to home businesses. Residential zones limit commercial activity, and the home occupation permit is how a city allows business use while capping its neighborhood impact: limits on signage, customer traffic, employees working on site, inventory storage, and sometimes the share of the home used for business. HOA rules and lease terms can add private restrictions on top of the public ones. The permit is usually inexpensive; operating without it where required is what gets costly.

Everything else is unchanged

The rest of the stack ignores your address. A home-based bookkeeper, contractor, lender, or collection operation needs the same state licenses as one in an office tower, and a regulated activity run from a spare bedroom across state lines is licensed by the states it reaches.
