Unfounded Fears Shouldn’t Drive Local Housing Plans? New Research Builds Upon Evidence that Common Complaints About Affordable Housing Impacts Are Groundless
In Connecticut’s towns affordable housing development debates often center on a familiar set of concerns: school costs, increased traffic, strained municipal budgets, and reduced public safety.
A new study examining large affordable housing developments built under Massachusetts’ Chapter 40B suggests that these concerns are generally baseless. For Connecticut local officials and state policymakers, the findings are especially significant because Chapter 40B is similar to Connecticut’s Affordable Housing Land Use Appeals Act, commonly known as Section 8-30g. Both laws were created to address exclusionary zoning practices and to ensure that municipalities contribute to meeting regional housing needs, making the Massachusetts evidence directly relevant to Connecticut’s current debate about how and where necessary housing growth should occur.
The research comes as municipalities are now charged with developing housing growth plans. Those plans should not become another place to recycle unsupported fears about housing growth. Local officials should look at this and other empirical evidence to test claims of negative impacts of desperately needed housing.
The study, Knock Knock: The Impact of Large Subsidized Housing Developments on the Surrounding Community by Sethu Odayappan, analyzed 65 large mixed-income developments built in Massachusetts communities subject to Chapter 40B. The average development studied had more than 200 apartments.
The results directly challenge many of the claims that routinely surface in local opposition.
A common argument against affordable housing is that new residents consume more in public services than they contribute to tax revenue. The Massachusetts evidence tells a different story.
The study found no evidence that large affordable housing developments weakened municipal fiscal health. Communities experienced substantial growth in their residential tax base following project completion, while bond ratings and broader fiscal indicators remained stable. Importantly, municipalities did not need to increase property taxes on existing residents to accommodate growth.
In other words, the developments added housing and population without producing the fiscal distress often predicted by opponents.
Concerns over exploding school enrollment are among the most politically potent objections to multifamily housing proposals. Other research and empirical evidence have long shown that new multifamily housing does not result in significant increases to school enrollment. In this study, while the developments did add students to local school systems, there was no measurable increase in class sizes and no evidence of declining school performance based on available indicators.
The study also examined two other frequent concerns: public safety and transportation impacts. Researchers found no measurable increase in arrest rates following development. Nor did they find evidence that the new housing worsened traffic conditions when evaluating community-level indicators such as commute times and crash data.
The parallels to Connecticut are clear. Like Chapter 40B, Section 8-30g was enacted because organized opposition and local zoning decisions often make it difficult or impossible to build affordable housing in communities with limited existing supply. Both statutes recognize that housing shortages are not merely local concerns; they are regional and statewide challenges.
Connecticut continues to face a severe shortage of both affordable and market-rate housing. Yet opposition to any new housing, but especially new multifamily development, is frequently justified by predictions of fiscal burdens, overcrowded schools, traffic congestion, and public safety concerns.
This study suggests that we can build more housing, including multifamily and mixed-income development, without assuming that new homes weaken a community. Rather, we can strengthen our communities while expanding access to the homes that Connecticut residents increasingly need without these negative effects. The Massachusetts experience shows that, across dozens of communities and thousands of housing units, researchers did not find evidence that large mixed-income developments undermine municipal finances, school quality, public safety, or transportation systems.
As Connecticut continues to grapple with a housing shortage and ongoing debates over Section 8-30g, policymakers and local officials should focus on the growing body of empirical evidence rather than longstanding unfounded assumptions. If the most common local fears about affordable housing development are baseless, then what drives opposition that can be so vicious and disturbing?
Anyone that’s spent time around affordable housing development public hearings has heard enough to believe that local opposition is too often based upon a belief that their community exists in a zero sum world where any new housing must result in a degrading of a community’s quality of life. (Thankfully for critics, residents weren’t so insistent in that belief when their homes were built.) This says nothing about the litany of classist and racist suspicions that are regularly expressed in these hearings and elsewhere. Opponents can insist that this is not the case. Either way, the fact remains that empirical evidence repeatedly shows that the most common impacts that residents and local officials point to as justification for opposition to multifamily housing development are decidedly NOT supported by evidence.
And we are left to consider a final question from the study’s author: “the findings raise a broader political economy question: why does opposition persist if large mixed-income developments do not measurably reduce municipal fiscal health or service quality?”
