Best accessory dwelling unit — Cambridge, MA

In Cambridge, an accessory dwelling unit (ADU) refers to a secondary, independent living unit created on a lot with a single-family or multi-family dwelling. These units must contain basic provisions for living, sleeping, cooking, and sanitation. Cambridge has specific zoning regulations that dictate the size, placement, and occupancy of ADUs, often with requirements to maintain neighborhood character and housing affordability. Understanding these local rules is critical for any ADU project.

While a precise figure requires a detailed site assessment and quote, expect costs to reflect the premium nature of construction in this area.
