ADU Design-&-Build Services by River City Boston

If you’re ready to add an Accessory Dwelling Unit (ADU) on your Boston-area property, River City Boston is your all-in-one partner: we handle design, permitting, construction, and full project management.

Why Choose an ADU?

An ADU offers your property flexibility, additional value, and functional living space. Whether you’re looking to generate rental income, accommodate family, or simply maximize your land — this is a smart investment.

  • Local expertise: Boston and surrounding communities.
  • Transparent process: you stay informed, on-schedule and on-budget.
  • Quality craftsmanship: built for durability, aesthetics, and functional living.
