Why Now Is the Best Time for New England Homeowners to Build an ADU

In Massachusetts, homeowners are seizing the moment to invest in ADUs, turning unused backyard space into income and long-term value

Massachusetts homeowners have more financing opportunities than ever before to make building an Accessory Dwelling Unit (ADU) — also called an additional dwelling unit — affordable and achievable. With housing costs rising across New England, new programs from local lenders, credit unions, and state-backed initiatives are making ADU financing simpler—helping families unlock fresh income, flexibility, and long-term property value.

This article is for homeowners still “on the fence” about adding an ADU. Funding is available now, but the sooner you start, the faster you’ll enjoy the financial and lifestyle benefits.

ADU Financing Options in Massachusetts

Massachusetts homeowners can access a broad mix of financing solutions through local lenders and statewide programs, such as:

• Home equity loans and ADU-specific mortgages.

• HELOCs (Home Equity Lines of Credit) that let you borrow against the value of your home.

• Construction loans and conventional mortgages for larger projects.

• Refinancing programs that factor in projected rental income.

• Long-term loans (15–30 years) where rental income may help with approval.

Municipal & State-Backed Programs

• Boston Home Center ADU Program — Up to $50,000 in zero-interest loans plus $7,500 in technical assistance for qualified homeowners.

• Boston ADU Bank Pilot — Zero-interest loans offered in partnership with local institutions.

• Home Modification Loan Program (HMLP) — 0% interest, deferred loans up to $50,000 statewide for accessibility-focused ADUs.

With so many options available, there has never been a better time to finance an ADU in Massachusetts.

Why Build an ADU or Prefab ADU Now?

Homeowners across New England are embracing ADUs and prefab ADUs as a smart, long-term investment. The benefits speak for themselves:

• Boost property value — Significantly increase resale potential.
