You can franchise any business, but franchises are suprisingly complex legally--there is a whole body of law relating to franchises. There are many other options you can explore: giving them some ownership interest in your business's LLC or corporation (you do have an LLC or corporation, don't you, to protect you from liability), though you should keep a majority ownership interest (and control) for yourself); creating new LLCs for them, partially owned by them, and partially by you/your LLC; giving them a share of profits without giving them ownership (e.g. they get X% of the revenue); etc. Consult with a local business attorney to explore what option is bet for you.
