In the state of Florida you can only qualify one business with your license without going before the board.
You can only pull a permit under the business name your license is attached to, unless you pull one as a homeowner (which only works for your house).
So, if you pull a permit for work that is being done by someone other than the company your license is attached to....well, it's my understanding that's illegal.
I think the same restrictions apply when "advertising" using your license number for a business your license isn't attached to (i.e. either the primary or secondary qualifier).
I believe other states are very similar.
Maybe consulting would be different as you really don't need a license to "consult" depending on what you claim you can do.
