Why joining matters

Every ADU-proficient pro who joins makes the next project easier.

The hard part of an ADU isn't the build. It's the handoffs. A single project passes through eight or more sets of hands, and it moves at the speed of the one who doesn't know ADU rules. The ADU Exchange exists so that, in every territory, every one of those hands already does.

Two minutes on why an ADU is not a small addition, and what the Ecosystem does with a pro who already knows that.

For homeowners

One place where everyone already speaks ADU.

  • 1No re-explaining. The electrician doesn't need the zoning lecture. The lender doesn't ask "what's an ADU?" The appraiser has comps.
  • 2Fewer stalls. Most ADU delays aren't construction. They're a permit bounced for a setback error, a design that ignored the state's by-right size limit (up to 900 sq ft in Massachusetts, for example), a loan that didn't fit. Proficient pros don't make those.
  • 3A real roster, by territory. Not a national lead site reselling your phone number. Pros who actually work where you live, placed by the towns they serve.

For professionals

A denser network sends you better-prepared work.

  • 1Cleaner handoffs. When the designer upstream knows the bylaw and the GC downstream knows your scope, your part of the job starts ready instead of half-baked.
  • 2Referrals that flow both ways. Master GCs need trades. REALTORS® need lenders. Lenders need appraisers who understand ADU value. Every proficient member in a territory is a referral source for every other one.
  • 3You compete on ADU competence, not price. Homeowners here are looking for someone who has done this before. That's the whole filter.

What "ADU-proficient" means here

Membership isn't a badge for showing up. It's a signal to homeowners and to every other member that you can carry your part of an ADU project without slowing it down.

  • Knows the state ADU law that applies to the property
  • Knows how the local bylaw differs from the state floor
  • Has run a job through a building department, start to finish
  • Hands off clean: drawings, specs and status the next trade can use
  • Quotes ADU work as ADU work, not as a "small addition"
  • Answers a homeowner request within two business days

Limited seats · first come, first served

Every trade has four seats per territory. That's it.

Like the Master GC program, membership is capped. In each of our 40 New England territories, every trade and service gets one Sponsor, one Territory and two Verified seats. When all four are taken, the trade is closed in that territory, and free listings there come off the map.

only until the 4 paid seats fill
Why cap it? Homeowners get a short list of committed ADU pros instead of a phone book, and every member competes with three others at most, not thirty. Seats are sold one territory at a time. REALTORS® are not seat-limited.

Regional Sponsorships

Manufacturers & regional companies

Modular and prefab builders, suppliers and companies that serve a whole region don't fit a single-trade, single-territory seat. Regional sponsorships are arranged separately, sit outside the four-seat grid, and never take a local pro's seat.

Important: Membership provides profile visibility, positioning and access to the ADU Exchange ecosystem. It does not guarantee a specific number of leads, projects or closed jobs. Master General Contractor participation is a separate reviewed program.
Separate Builder Pathway

Master General Contractor Partners

The Master GC program is separate from standard professional membership. One Master GC is selected for each territory and serves as the accountable build-side connection for homeowners moving from feasibility toward construction.
