It depends on zoning, agricultural or residential? Agricultural allows almost everything. You might contact the township office for the address in question and ask.
JMHO ~ What you are talking about doing is essentially a sole person "consulting" business. You do the "work" at the clients house and you simply do the business paperwork at your home. In the places where I have lived doing this kind of work has nothing to do with your place of residence being zoned commercial or business. As long as you do not do training sessions or pet sitting at your house you are a "consultant." And from a business perspective you can operate as DBA, LLC, or S corp (whichever makes more business sense from your accountants point of view).
I would also go to your local county/city and ask what their rules on consulting from home are. Usually they are fairly straight forward.
Good Luck
