Common questions

How big can an ADU be in Massachusetts?

Potential downsides include the upfront investment and the importance of navigating complex local permitting processes. Proper insulation and heating systems are crucial for the Massachusetts climate. We manage these factors to ensure your ADU is a sound, long-term investment.

Exploring prefabricated or modular ADU options can also reduce build times and associated labor costs. We guide you toward efficient solutions for your New Bedford property.
