BALLSTON SPA, N.Y. — When a 7-year-old boy’s lemonade stand was shut down by a health inspector here last month, it became the talk of the town. Gov. Andrew M. Cuomo weighed in. A New York State senator introduced legislation in the boy’s name, and the roadside drink entrepreneur’s photo was splashed across newspapers around the country.

But, at the end of the day, Brendan Mulvaney just wanted to sell lemonade. So, on Saturday, Brendan and his family reopened the lemonade stand for one more day. Instead of raising money for a trip to Disney, as Brendan had planned to do the first time around, he and his family sought to capitalize on his newfound fame to raise money for a local family in need.

Last month, Brendan set up his lemonade stand on the side porch of his house, just as he had done for the past two years during the Saratoga County Fair. This year, Brendan hung new signs, printed by a family friend, and with the help of his parents, added water and snow cones to the stand’s menu.

But an inspector with the state Department of Health soon told the Mulvaneys that they needed a permit because their venture was similar to those of permitted vendors at the fair, said Jill Montag, a health department spokeswoman. (Ms. Montag said at least four vendors inquired about the Mulvaney family’s stand.)
