These rules can vary from state to state. We recommend checking with your state real estate inspection licensing services for these guidelines. Unfortunately, we are unable to give legal advice in Home Inspection Professional License Law. From your maps, it seems like you are in New York. I have provided a link to the Division of Licensing Services in New York which can give you more information on whether you can advertise for these services.
Please let us know if you have any questions. We will do our best to help where we can.
