In Village of Belle Terre v. Boraas, 416 U.S. 1 (1974), the Supreme Court held 7-2 that a local government may define “family” in its zoning code to bar more than two unrelated people from sharing a home, and that such an ordinance draws only rational basis review rather than any heightened constitutional scrutiny. The ruling remains the federal foundation for single-family zoning restrictions, though later Supreme Court decisions, the Fair Housing Act, and several state supreme courts have carved significant limits into how far it reaches.1Justia. Village of Belle Terre v. Boraas, 416 U.S. 1 (1974)
What the Supreme Court Held
Justice William O. Douglas, writing for a seven-justice majority, reversed the Second Circuit and upheld the ordinance. The opinion’s central move was classifying the zoning law as ordinary social and economic legislation rather than something touching a fundamental right or a suspect class. That classification decided almost everything that followed.2Library of Congress. Village of Belle Terre v. Boraas, 416 U.S. 1 (1974)
Because no fundamental right was at stake, the Court applied rational basis review, the most deferential standard in constitutional law. Under it, a court presumes the law is valid and asks only whether any conceivable legitimate purpose supports the line the legislature drew. The challenger has to prove the law is irrational. Laws almost never fail that test, and Belle Terre’s did not.
Douglas found the village’s interests easy to accept. A community, he wrote, has a legitimate interest in preserving “family values, youth values, and the blessings of quiet seclusion and clean air.” Restricting density, noise, traffic, and the transient character of a residential neighborhood were all legitimate ends, and treating unrelated groups differently from related ones was neither arbitrary nor unreasonable in service of those ends.2Library of Congress. Village of Belle Terre v. Boraas, 416 U.S. 1 (1974)
The Court rejected each constitutional theory the challengers raised. Equal protection failed because no suspect class was involved and the related/unrelated distinction survived rational basis. The associational and privacy claims failed because the Court declined to extend the fundamental-rights precedents on voting, political association, court access, and contraception into the zoning context.
Had the Court instead found a fundamental right implicated, strict scrutiny would have applied. Under that standard the village would have had to prove a compelling interest and narrow tailoring, and its ordinance would likely have failed, because less restrictive tools existed: occupancy limits tied to square footage, parking limits tied to vehicles, noise ordinances tied to noise. The choice of standard, more than anything else, drove the outcome.
The Ordinance and How the Case Reached the Court
Belle Terre is a small village on Long Island’s north shore. Its zoning code permitted only single-family dwellings and outright banned lodging houses, boarding houses, fraternity houses, and multi-family buildings. The definition of “family” was the piece that mattered. People related by blood, adoption, or marriage counted as a single family with no cap on household size. Unrelated individuals were capped at two.1Justia. Village of Belle Terre v. Boraas, 416 U.S. 1 (1974)
The Dickmans, who owned a house in the village, leased it to six students from the State University at Stony Brook. None were related. When the village ordered the owners to fix the violation, they and three of the tenants sued under 42 U.S.C. § 1983, seeking a declaration that the ordinance was unconstitutional and an injunction against enforcement.1Justia. Village of Belle Terre v. Boraas, 416 U.S. 1 (1974)
The Dissents
Justice Thurgood Marshall dissented on the merits. In his view the ordinance burdened fundamental rights of association and privacy protected by the First and Fourteenth Amendments, and the Court should have applied strict scrutiny. The freedom to choose one’s household companions, he argued, involves “deeply personal considerations as to the kind and quality of intimate relationships within the home,” and the right to establish a home is “an essential part of the liberty guaranteed by the Fourteenth Amendment.”2Library of Congress. Village of Belle Terre v. Boraas, 416 U.S. 1 (1974)
Marshall also attacked the ordinance’s internal logic. It was, he said, both overinclusive and underinclusive: no cap on how many relatives could occupy a house, but a hard limit of two for unrelated occupants regardless of the home’s size, its residents’ income, or how many cars they parked outside. Density, traffic, and noise could be addressed directly, without a rule that turned on bloodlines.
Justice William Brennan dissented on a threshold ground. The student tenants had moved out before the case reached the Supreme Court, and Brennan questioned whether a live case or controversy still existed and whether the homeowners could assert the constitutional rights of tenants no longer affected by the ordinance.1Justia. Village of Belle Terre v. Boraas, 416 U.S. 1 (1974)
Moore v. East Cleveland: The Family Boundary
Three years later the Court signaled that Belle Terre’s deference had a hard limit when the people being separated were relatives. In Moore v. City of East Cleveland, 431 U.S. 494 (1977), the Court struck down a zoning ordinance so narrowly written that it prevented a grandmother from living with her two grandsons because they were cousins rather than siblings.3Justia. Moore v. City of East Cleveland, 431 U.S. 494 (1977)
Justice Lewis Powell, writing for a plurality, distinguished Belle Terre on the ground that it dealt with unrelated individuals, while the East Cleveland ordinance “sliced deeply into the family itself.” The Due Process Clause, Powell wrote, protects the sanctity of the family because that institution is “deeply rooted in this Nation’s history and tradition,” and the protection extends beyond the nuclear family to grandparents, aunts, uncles, and cousins. East Cleveland’s stated interests in preventing overcrowding, traffic, and school-financing strain bore only a “tenuous relation” to the restriction, and the usual deference did not apply.3Justia. Moore v. City of East Cleveland, 431 U.S. 494 (1977)
Together, Belle Terre and Moore mark the current federal boundary. A municipality may restrict groups of unrelated people, but it may not use its zoning definition of “family” to break apart a family.
Fair Housing Act Limits on Family Composition Rules
Federal civil rights law imposes its own constraints on Belle Terre-style zoning. The Fair Housing Act prohibits housing discrimination based on race, color, religion, sex, familial status, national origin, and disability.4Office of the Law Revision Counsel. 42 USC 3604 The statute exempts “reasonable local, State, or Federal restrictions regarding the maximum number of occupants permitted to occupy a dwelling,” but the Supreme Court has read that exemption narrowly.5Office of the Law Revision Counsel. 42 USC 3607
In City of Edmonds v. Oxford House, Inc., 514 U.S. 725 (1995), the Court divided local housing rules into two categories. Occupancy limits based on floor space or number of rooms, designed to prevent overcrowding, fit within the exemption. Zoning definitions of “family” that cap unrelated occupants to preserve neighborhood character are family composition rules and do not qualify for the exemption.6Justia. City of Edmonds v. Oxford House, Inc., 514 U.S. 725 (1995)
The distinction matters most for group homes serving people with disabilities. Where a city’s family definition excludes a recovery house or a group home, the Fair Housing Act may require the city to grant a reasonable accommodation in its zoning code. A Belle Terre-style rule cannot be used to block housing for protected groups without exposing the municipality to federal liability.
States That Have Rejected Belle Terre
Belle Terre sets a federal floor, not a ceiling. Several state supreme courts have interpreted their own constitutions to give household arrangements more protection than the federal Constitution provides.
California struck down a materially identical ordinance in City of Santa Barbara v. Adamson (1980), holding that the state constitution’s explicit right to privacy protects the choice of household companions and that capping unrelated occupants bore no rational relationship to the city’s stated goals. Density could be controlled through floor-space rules, parking through vehicle-based limits.7Justia Law. City of Santa Barbara v. Adamson
Michigan’s high court parted company with the U.S. Supreme Court explicitly in Charter Township of Delta v. Dinolfo (1984). Belle Terre, the Michigan court wrote, “made no attempt to suggest how a line drawn between the related and the unrelated advances” the stated goals of zoning. Whether the line bore a rational relationship to those goals was a judicial question, and the ordinance failed under the state constitution’s Due Process Clause.8Justia Law. Delta Charter Township v. Dinolfo
New Jersey took a different path in Borough of Glassboro v. Vallorosi (1990), adopting a functional-family test. A municipality may restrict a zone to single housekeeping units, but the standard for qualifying “must be functional, and hence capable of being met by either related or unrelated persons.” Unrelated occupants who show stability, permanency, and a shared domestic life can meet the definition.9Justia Law. Borough of Glassboro v. Vallorosi
New York reached a similar functional test in City of White Plains v. Ferraioli, decided the same year as Belle Terre. A municipality cannot exclude a household that is “the functional and factual equivalent of a natural family” from a single-family neighborhood.
What Belle Terre Means Today
Belle Terre remains good law at the federal level. Zoning codes that limit unrelated occupants are still evaluated under rational basis review in federal court, and many communities continue to enforce them. What has changed is what surrounds the rule. Moore prevents municipalities from using zoning to split up extended families. The Fair Housing Act, as read in Edmonds, subjects family composition rules to federal anti-discrimination requirements and can require accommodations for group homes. Several of the country’s most populous states have rejected Belle Terre’s reasoning under their own constitutions, applying either a functional-family test or a stricter rational-relationship review.
The practical answer for anyone facing a household-composition restriction depends on three layers: the federal constitutional floor from Belle Terre and Moore, the federal statutory overlay of the Fair Housing Act, and the state constitution and case law of the jurisdiction where the property sits. The Supreme Court’s 1974 ruling still frames the analysis, but it no longer supplies the whole of it.
