ADU Construction — Frequently Asked Questions
What is the MA 2024 Affordable Homes Act ADU rule?+
The Affordable Homes Act of 2024 allows homeowners to build ADUs up to 900 sq ft as-of-right (without variance or special permit) in single-family zoning districts statewide. This is a massive change that makes ADU construction far easier.
How much does an ADU cost to build in MA?+
ADUs in Massachusetts typically cost $150,000–$350,000+ depending on whether they are attached, detached, or a conversion. Basement/garage conversions are typically more affordable.
Can I rent my ADU?+
Yes! ADUs can be rented as long-term units. In Greater Boston, ADUs typically rent for $1,500–$3,000+/month depending on location and size.
Do I need to notify my insurance company before building an ADU?+
Yes. Adding an ADU changes your home's risk profile. We recommend notifying your insurer before construction begins and consulting a licensed MA insurance agent.
