ABOUT ONEBUILD
We turn unused yard space into legal, high-performing backyard homes for family or rental income. We guide you from ‘is this even possible?’ to a clear plan you can build.
Today’s homeowners face a new reality: rising housing costs, aging parents, grown kids moving back home, and the need for extra income. At OneBuild, we turn those challenges into lasting opportunities through Accessory Dwelling Units (ADUs), small independent living space built on the same property as an existing home.
An ADU offers flexibility and financial freedom, whether it provides housing for family, a private guest retreat, or a steady source of rental income, without the stress of traditional construction. Each OneBuild model is architect-designed, prefabricated, and precision-built to the highest standards, then delivered directly to your site and installed by our trusted team. Prefab means faster timelines, fewer surprises, and higher quality control, giving you a beautiful, efficient space ready in a fraction of the time.
Unlike others, OneBuild manages everything under one roof, from feasibility to permitting, delivery, and installation. There is no juggling contractors or navigating red tape. Our streamlined process saves time, reduces stress, and ensures every detail comes together perfectly. Rooted in the Hudson Valley, OneBuild delivers turnkey ADUs that bring families closer, create passive income, and build lasting value, one backyard at a time.
One Team. One Process. OneBuild.
WHAT WE DO
One Team. One Process. OneBuild.
FEASIBILITY & DESIGN
We start by evaluating your property’s zoning, setbacks, utilities, and site conditions. We provide a clear picture of what's possible and what it will cost. You’ll receive a feasibility report tailored to your lot, lifestyle, budget, and goals.
PERMITTING & PROJET MANAGEMENT
Our team handles permitting, approvals, and coordination with local building departments across the Hudson Valley. We keep your project compliant and on schedule so you never navigate complex regulations alone.
TRANSPARENT PRICING
We help you identify and evaluate prefab ADU options that fit your lot, budget, and goals. Your ADU is built off-site by our prefab partners and installed on-site by licensed contractors. Your new space arrives on time, on budget, and built to last.
