If you are remotely interested in opening a home-based business, you need to get educated on what (if any) zoning regulations are in place. For example, the State of Virginia allows home-based businesses, and in 2016 I built a single chair salon in my basement. But a business in a residential area has to conform to pre-set “Standards” that a business in a commercial area would not have to.
Those “Standards” are the rules a business like mine needs to follow. I live in the Town of Herndon. They have written their own standards, which supersede the State and County Standards. Meaning: Regardless of what the State of Virginia says about home-based businesses, I must adhere to what my town has written. This is actually a very good thing because if you find yourself unable to follow a Standard, the appeal process should be relatively simple because everything can be done on the local government level (as opposed to the county or state level).
