The All-In-One Solution for Your ADU Project
Your all-in-one ADU partner in Boston for design, permitting, and construction. Quality spaces, built efficiently.
As a full-service design-and-build partner, River City Boston takes full accountability for your ADU from design through construction and livraison. We make the process transparent and predictable, giving you a single trusted team rather than multiple dispersed contractors.
From your first conversation through handing you the keys to your finished ADU, you’ll work directly with us. Our experience means we anticipate issues less seasoned teams might overlook, and bring deep expertise to your project.


Why Choose River City Boston for Your ADU Project?
A strong ADU partner isn’t just a builder or an architect — it’s both. Here’s what sets us apart:
- Easibility & Budget: We evaluate your property to ensure an ADU fits your Boston lot, budget, and timeline—giving you clear, upfront expectations.
- Architectural Plans: Choose from efficient, pre-designed ADU floor plans or customize your own for flexible, cost-effective living space.
- Permitting & Compliance: We handle all ADU permitting and local code requirements across Greater Boston for a smooth, stress-free approval process.
- Design Selection: Select from curated interior and exterior finishes or collaborate on a custom design that complements your home.
- Construction: From site prep to final inspection, our team manages every phase of your ADU construction with precision and care.
- Project Management: Stay informed with transparent updates on progress, costs, and milestones—your ADU project, delivered on time and on budget.
