Our Story
Eastern Mass ADU was founded in late 2025 by brothers Rafael and Yosef Ellis-Rech to help Massachusetts homeowners expand their living spaces through high-quality, affordable accessory dwelling units (ADUs). Inspired by Rafael’s growing family of five and the state’s 2025 zoning law changes, we saw an opportunity to create tailored solutions for multigenerational living, rental income, or property enhancement. With roots in Sharon, Massachusetts, and a foundation built on five years of renovating homes through our prior venture, ERBrothers LLC, we bring hands-on expertise and a commitment to community-focused building.
​
We’re not about cutting corners or chasing volume. Our lean operation keeps overhead low, allowing us to deliver top-notch craftsmanship at a price that works for you. By focusing on fewer projects, we give each client our full attention, ensuring every detail—from permitting to final finishes—meets your vision and our high standards. Rafael oversees the construction process, leveraging his engineering background and Licensed Construction Supervisor (CSL) certification to ensure precision, while Yosef drives operations and business development, streamlining every step to keep your project on track.
​
Our first ADU, a custom build in Sharon, is set to deliver by the end of 2026, marking the start of our mission to transform properties across Eastern Massachusetts. Whether you’re creating space for aging parents, young adults, or renters, we’re here to build ADUs that blend seamlessly with your home and community. Quality, affordability, attention to detail, and community integration guide everything we do.
