This bill establishes the right to create accessory commercial units on any lot with a lawful principal use across all zoning districts in the state. An "accessory commercial unit" is defined as a subordinate commercial space that is incidental to the principal use and provides neighborhood-scale goods or services without causing excessive disturbances. The bill outlines a list of permitted uses for these units, including coffee shops, bakeries, salons, and various professional offices, among others. It also sets limitations on the size of these units, capping the floor area at 1,000 square feet or 25% of the principal structure's gross floor area, and restricts operational hours and signage.

Additionally, the bill prohibits municipalities from enacting more restrictive ordinances regarding accessory commercial units, ensuring uniformity in their establishment statewide. Municipalities may implement registration and inspection procedures for these units, but such procedures cannot be more stringent than the provisions outlined in the bill. The act will take effect 60 days after its passage.
