Mass. special committee hears expert, tenant and landlord testimony on proposed rent‑stabilization measure (H5008)

The Special Joint Committee on Initiative Petitions held a public hearing March 17 on initiative petition 20521 — filed as House Bill 5008 — a proposed statewide rent‑stabilization measure that would cap annual rent increases at the lower of the consumer price index or 5% and exempt owner‑occupied buildings of four units or fewer and new construction for 10 years.

Whitney Ergood Del Berkey, a senior research associate at the Harvard Joint Center for Housing Studies, opened the hearing with data on Massachusetts housing: “From 2019 to 2024, rents rose by 12% in real terms, while renter household incomes rose by just 4%,” she told the committee, adding that more than half of renters in the state are cost‑burdened. Her presentation outlined five central design questions for any rent regulation law — the size of allowable increases, which housing is covered, whether new construction is exempted, how vacancy resets are handled, and how oversight, enforcement and dispute resolution work in practice.

Proponents, represented by Carolyn Chu of Homes for All Massachusetts, framed H5008 as a second‑generation rent‑stabilization policy aimed at protecting tenants from rapid, investor‑driven increases. Chu said the campaign collected roughly 124,000 signatures and described the proposal as revenue‑neutral and targeted to stabilize communities while production and other affordability tools proceed. “This policy exempts owner‑occupied buildings with no more than four units,” Chu said, and “limits annual rent increases to the consumer price index with a maximum of 5%.” Tenants who testified, including Laura Frost from Arlington, described sharp rent hikes after out‑of‑town purchases and recounted organizing and legal fights to preserve housing.

Academic and national experts on the proponents’ side urged the committee to weigh recent empirical evidence. Dr. Mark Paul, an associate professor of economics at Rutgers, said that well‑designed stabilization can reduce turnover and protect long‑term residents. Traum Huang of PolicyLink described implementation lessons from other U.S. jurisdictions and said broad stabilization can reach large numbers of households quickly.

Opponents warned of unintended consequences. Tony Lopes of the Small Property Owners Association and municipal leaders argued the cap would squeeze small landlords and reduce incentives to maintain or invest in rental housing. Several witnesses cited a Tufts analysis that estimated a very large aggregate reduction in property values under statewide rent caps; Tony Lopes told the committee the Tufts analysis showed about a $300 billion fall in real estate value over 10 years if the proposal passed. John Gruber, chairman of MIT’s economics department, testified that high‑quality studies — including work on San Francisco — find rent regulation can lower rental supply and reduce property values, and he urged the committee to prioritize production and regulatory reform to increase housing supply.

Committee members pressed both sides on specifics: why a four‑unit owner‑occupied exemption was chosen, how short‑term rentals were carved out, the campaign’s signature and funding details, and empirical evidence about development or disinvestment. Proponents emphasized the grassroots signature effort and the policy’s exemptions; opponents urged caution about statewide, across‑the‑board price caps and warned of fiscal impacts for cities and towns if property values fell.

The committee did not take action on the petition at the hearing. Chairs and staff said written testimony would be accepted through 5 p.m. Friday, March 20, and the committee adjourned after a motion to close the hearing.

What happens next: The committee will collect written testimony through the stated deadline and may hold additional meetings or produce a report to the legislature recommending action on the petition. Any formal legislative action (a recommendation, referral or enactment) would be recorded separately.
