Frequently Asked Questions
Thinking about adding an ADU to your property? Here are answers to the questions we hear most often. Feel free to reach out if you'd like to talk through your specific situation.
An Accessory Dwelling Unit (ADU) is a secondary living space on your property — it can be detached, attached to your home, or converted from an existing structure like a garage or basement. ADUs are commonly used for rental income, aging family members, or guest space.
ADU regulations vary by town and lot. We're familiar with the zoning bylaws across the South Shore and can help you determine what's allowed on your specific property during our free consultation.
A typical ADU project takes 4 to 9 months depending on the type and scope. Permitting timelines vary by town, but we factor that in from the start and keep you informed throughout.
In most cases, yes. Many South Shore homeowners build ADUs specifically for rental income. We can point you toward local regulations so you understand your options before we break ground.
