You may have to check with your local town laws too. IIRC I went around to my closest neighbors and had them sign a simple note saying they were okay with my opening a dc, then I presented it to my local zoning board. There are many things to consider with this type of business, noise, parking, extra traffic, clients. Some neighborhoods wouldn't care for lots of kids making lots of noise while others are family oriented and approachable.
And while you're right that it is *your* home, we don't always get to do everything we want.
Just to build a deck or change the outside of our homes, we have to go through all kinds of @rap.
