Thanks for reply, Miriam. I'm glad to know it doesn't have to be on the home page. It's possible for me to put it in the footer, but it would be more hassle than it's worth, so I wanted to make it clear for answering purposes that I didn't want to do that.

I have a local business with a contact page that I want to add schema markup to. However, I was wondering if having the address with schema info on the contact page instead of the home page has any adverse effects on the rich snippet showing up in search.

There's no logical place to add schema for a local business on the home page, so having it on the contact page—not in the footer or sidebar—is the only option.
