What are the local zoning regulations for 316 Union St ?

RH-3 (RESIDENTIAL- HOUSE, THREE FAMILY)

RH-3 districts are similar to RH-2 districts, but it's more common to find buildings with 3 units alongside one and two-family homes. These areas are mainly made up of large flats rather than apartment-style housing, with each unit typically having its own separate entrance.

The number of residential units in the RH-3 district is calculated based on the size of the lot, but it cannot exceed 3 dwelling units per lot.

Dwelling Unit: A room or suite of two or more rooms that is designed for, or is occupied by, one family doing its own cooking therein and having only one kitchen.

Accessory Dwelling Unit (ADU): Also known as a Secondary Unit or In-Law Unit. It is accessory to at least one other Dwelling Unit on the same lot. A detached ADU should not share structural walls with the primary structure on the lot.

Junior Accessory Dwelling Unit (JADU): JADU is a secondary living space within a single-family home, limited to 500 square feet. It must have its own entrance, an efficiency kitchen, and can either share or have separate sanitation facilities. The property owner must live on-site unless a government agency, land trust, or housing organization owns the unit.

These districts are predominantly made up of large flats rather than apartments. Building styles are varied but generally complementary. Outdoor space is available at ground level, as well as on decks and balconies for individual units. Nonresidential uses are more common here than in RH-2 districts.
