COMMON QUESTIONS

ADU Construction FAQs for Westborough Homeowners

  • How long does ADU construction take in Westborough?

    Timeline varies by ADU type. Garage conversions take 3-5 months, while detached ADUs take 6-10 months from permits to completion. We provide detailed schedules during planning.

  • Can I rent out my ADU in Westborough?
