For homeowners looking to add an Accessory Dwelling Unit (ADU) to their property, working with experienced ADU contractors in Essex, MA is essential to navigate the town's unique regulatory landscape.
Essex falls under Massachusetts General Law Chapter 40A, which was amended to encourage ADU development across the state. However, local zoning bylaws in Essex still play a significant role in determining what is permissible on a given property.
