ADU Parking Requirements in Worcester, MA

ADU Regulations in Worcester

Worcester may also have additional local regulations that supplement the state baseline.
Transit Parking Exemption in Worcester
Worcester has transit stations, which means properties within 0.5 miles qualify for a complete parking exemption. This exemption applies to subway, commuter rail, bus rapid transit, light rail, and ferry terminal stations. Use our address checker to see if your property qualifies.
Meeting the Parking Requirement
To meet Worcester's 1-space requirement, you can use existing driveway or garage spaces, create new on-site parking, or (if near transit) qualify for the exemption. Consider how the parking layout affects your ADU's size and placement on the lot.
How the Transit Exemption Works
The transit parking exemption in Worcester is measured as a straight-line distance from your property to the nearest transit station entrance. If you're within 0.5 miles, your ADU has zero parking requirements — this right is guaranteed by the Affordable Homes Act. This can free up significant lot area for the ADU itself.
