Prohibits sale and use of certain gas-powered leaf blowers; provides CBT credit for purchase of electric leaf blower that replaces gas-powered leaf blower.

S 623 bans the sale and use of gas-powered leaf blowers with two-stroke engines after two years and restricts four-stroke models in residential areas after four years, allowing limited non-residential use only during March 15-May 15 and October 15-December 15. It exempts gas blowers used for pest management applications and imposes penalties: $500-$1,000 for businesses and $25 for individuals for violations. The bill also creates a 50% tax credit (up to 50% of purchase cost, including batteries) for homeowners and businesses replacing gas blowers with electric models, valid for five years after the bill’s effective date. This directly affects residents, property managers, and landscaping businesses operating in New Jersey.
