What Backyard ADUs does
Backyard ADUs is a New England-based design-build construction company founded in 2019 that plans, designs, develops, and constructs Accessory Dwelling Units (ADUs) — small detached or attached backyard homes — for residential property owners across Maine, Massachusetts, and New Hampshire. The company operates from offices in Easthampton, MA (headquarters) and Brunswick, ME, with a team of 11-50 employees including licensed professional engineers and licensed general contractors in multiple states.
The core product is a factory-built modular ADU combined with on-site construction, using PBS Modular as its factory partner for climate-controlled module production (approximately two-week factory cycle) and specialized on-site techniques including Insulated Concrete Form (ICF) foundations and frost-protected shallow foundations that enable year-round construction in New England winters. The product lineup includes the S-Line, Square, and Jade design paths (400-575+ SF), all offered as Net Zero Ready — surpassing stretch energy code by approximately 20% and capable of operating for less than $700 per year including heating and cooling, with optional solar lease add-on. Revenue is generated primarily through one-time design-build construction contracts with homeowners, with a $600 feasibility study serving as the front-end conversion tool. The go-to-market motion is direct-to-consumer, with dedicated Small Home Advisors covering Massachusetts (Easthampton, Whately, Northampton, Amherst, Cape Cod) and Maine (Portland, Brunswick, Rockland), supported by content marketing, email newsletters, earned media in major regional outlets, and active community engagement including municipal zoning board participation and policy advocacy. Customer segments are residential homeowners seeking ADUs for multigenerational living, housing aging parents, generating rental income, or downsizing; a secondary segment involves landowners for "Tiny Home Infill Villages" micro-development projects.
