In 2014, New York State passed a law allowing the use of sparklers and small ground fireworks leading up to the Independence Day holiday and New Years Eve. However, there's a catch to the law - It's only legal in counties that pass a local law to use them. According to syracuse.com, permanent and specialty fireworks retailers that are certified by the state are allowed to sell sparklers from June 1 - July 5. Temporary stands or tents have from June 20 - July 5 to sell them.

These are Upstate NY counties that allow sparklers:
