Starbucks has definitely no minimum separation rules. In large cities in America I've seen blocks with more than four starbucks in total, that is to say, more than one outlet per side, and single stretch of street with three Starbucks: two in one side, one in the other.

When I was in Tokyo recently, walking to the Gotanda station, I counted four (!) Family Mart variety stores within the distance of maybe 300m.  Variety stores do huge business in Japan, but four stores so close together was still a shock.

Most franchisers will try to keep the locations somewhat separate to ensure the health of the individual franchises.  Two locations too close together are not good for anyone's business -- the question is just what constitutes "too close".
