2 days ago: Greylock joins MassHousing ADU program

Overview

Updated 1 hour ago

Massachusetts needs at least 222,000 new homes over the next decade. Accessory dwelling units (backyard cottages, converted basements, over-garage apartments) are one way to add them without new land or large-scale construction.

Greylock Federal Credit Union, based in Pittsfield, has joined MassHousing's Accessory Dwelling Unit Loan Program. The credit union says it's the first Berkshire County lender in the program, which pairs interest-bearing loans with zero-interest deferred financing for income-eligible homeowners.

Why it matters

If ADU lending scales, Massachusetts homeowners gain a new way to add housing and rental income without new land or large developments.

Historical Context

2 moments from history that rhyme with this story — and how they unfolded.

2010-2016

Portland's ADU fee waiver (2010-2016)

Portland waived system development charges for ADUs starting in 2010, cutting the cost of adding a unit by thousands of dollars. Annual ADU permits rose from about 100 to more than 800 by 2016.

Then

Portland became an early US leader in ADU construction, adding thousands of units.

Now

The city reinstated some fees as the program matured, showing how financial incentives can be adjusted.

Why this matters now

Portland shows how removing cost barriers changes construction volumes. Massachusetts is using a different lever: cheaper capital through state-backed loans.

2017-2022

California's ADU boom (2017-2022)

California passed laws in 2017 and 2019 making accessory dwelling units legal by right in most residential zones, overriding local restrictions. ADU permits grew from roughly 1,200 in 2016 to more than 20,000 in 2022.

Then

ADUs became a major source of new housing in California, especially in coastal cities where land is scarce.

Now

California's by-right model became the template for other states, including Massachusetts.

Why this matters now

Massachusetts copied California's by-right approach in 2024. California's trajectory shows the potential scale, but also that financing and construction costs are the next hurdle after zoning.
