17R Harding Rd in Norwood is a two-bedroom ADU we designed — 756 square feet, two bedrooms, one bath. Our work was the drawings and the stamp; a contractor built it from them. It is finished, occupied, and was listed at $2,246 a month in January 2026.
“Permit-ready” is an easy thing to claim. This set went through a real building department and a real contractor, and came out the other end as a dwelling somebody lives in. More on ADUs in Norwood.
That rent is what this specific unit was listed at on that date — not a projection for your property. Rents vary by town, size, and condition, and we don't forecast them.

Under the Affordable Homes Act, ADUs under 900 sq ft are now allowed by right in single-family zoning districts statewide — no special permit, no zoning board. Boston has its own citywide path under Article 53. Either way, the old “will the town even let me?” question is answered.
Boston-area rents are among the strongest in the country. A permitted ADU turns unused yard space into a long-term income stream.
An in-law suite for aging parents, a landing spot for adult kids, or a home office — independent space without leaving the property.
A second permitted dwelling on the lot is a durable improvement — one buyers and appraisers both recognize.
Every Sequoia Lodges package is a full drawing set — the same documents a custom architect would produce over months, ready on day one.
Published by The ADU Exchange, a New England ADU network. Sequoia Lodges is a design partner.
