Frequently asked questions

What is an ADU

12

 An Accessory Dwelling Unit (ADU) is a secondary living space located on a single-family residential property. ADUs can be detached, attached, or converted from existing structures, subject to local zoning regulations. 

Are ADUs legal in Massachusetts?

15

 Yes. Massachusetts allows ADUs statewide, though local zoning bylaws, setbacks, size limits, and permitting requirements vary by town. We work directly with local building departments to ensure compliance. 

How long does it take to build an ADU?

22

 Typical timelines:

  • Design & permitting: 3–6 months (varies by municipality)
  • Construction: 6–9 months

Total project duration depends on permitting, site conditions, and complexity. 

Do you handle permits and approvals?

22

 Yes. We assist with:

  • Design coordination
  • Engineering
  • Local permitting
  • Inspections

Final approval timelines are controlled by the municipality. 

Why do site conditions affect cost so much?

22

  

Items like soil quality, utilities, drainage, and access are often unknown until evaluation. These factors can significantly impact excavation, foundations, and infrastructure.

This is standard for all residential construction in Massachusetts.

Do ADUs increase property value?

22

  

 In many cases, yes. ADUs can:

  • Increase property value
  • Provide rental income
  • Support multigenerational living
  • Improve long-term usability of the property

Market impact varies by location and design. 

Do you offer design-build services?

22

  

  Yes. We work with trusted designers and engineers to provide a streamlined design-build approach, reducing delays and miscommunication. 

Can an ADU be fully ADA-compliant?

22

   Yes. We have extensive experience building fully ADA-compliant and universally designed homes, including features for mobility, aging-in-place, and long-term accessibility.
