Backyard ADUs

Backyard ADUs is a modular accessory-dwelling-unit design-build company that says it is headquartered in Brunswick, Maine and works across Maine, Massachusetts and New Hampshire, with a Massachusetts phone line and a model ADU in Barnstable. Its founders say the company started in late 2019, after they realised people could build tiny homes in New England backyards, and that their first client came from a neighbour's post in a local town Facebook group; the site claims six years in business. The business is led by Chris Lee, Head of Design & Development, a Maine native based in Brunswick, with Austin Gregory as Chief of Operations & Engineering. Its units are built modularly off-site in either Maine or Pennsylvania and then delivered and set — one 2025 report describes a unit delivered in two modular boxes and craned into place. There is real Massachusetts activity behind that. The Boston Globe described a 740-square-foot model unit in Cotuit in April 2025; Banker & Tradesman published an example of one of the company's units installed at a property in Concord in November 2025; and Canary Media reported in August 2026 that Marsha Gleason built an 800-square-foot accessory dwelling unit in her backyard in Northborough, Massachusetts, when she decided it was time to downsize. Chris Lee told NBC Boston in 2024 that interest had exploded in the preceding month. What is missing is customers. There are no customer reviews on file from any platform — not one. The only opinion in the record is a Reddit commenter in August 2026 who wrote that Backyard ADUs "is a reputable and good regional company", which is genuine word of mouth but is one person's view, and a second commenter who described it simply as a modular ADU company. Everything else is press coverage that names the firm rather than assessing it, so no rating is published here. Two things to establish directly. The company's own site names Austin Gregory as a Licensed Professional Engineer in six states and a licensed General Contractor in Massachusetts, but states no licence or registration numbers and nothing has been verified against any registry — ask for the numbers and check them with the Commonwealth. And the firm is Maine-headquartered with modular production in Maine or Pennsylvania, so confirm who holds the Massachusetts contract, who does the site work and foundation, and who warranties the finished unit. This is a company to talk to if you want a factory-built ADU set on a Massachusetts lot rather than a stick-built addition. Ask for references from completed Massachusetts installations, since the public record has coverage but no customer accounts.
