Overview
This legislation establishes a statewide preemption of local occupancy ordinances that restrict the number of unrelated individuals who may reside together in a single dwelling. The bill's central objective is to eliminate a longstanding form of housing discrimination embedded in many municipal zoning and occupancy codes — the practice of defining permissible household composition by familial relationship. By adding a new section to the preemptions chapter of Title 53, the Commonwealth asserts that decisions about who may live together in a home are not a legitimate subject of local regulation when based solely on whether occupants share blood, marriage, adoption, or foster care ties. The bill reflects a broader national trend toward housing liberalization, recognizing that occupancy restrictions tied to family status disproportionately burden non-traditional households, unrelated roommates, multigenerational living arrangements, and individuals seeking affordable shared housing. The legislation preserves local authority to regulate occupancy on genuine health and safety grounds, ensuring that the preemption does not override legitimate building, fire, and environmental standards.

Core Provisions
The bill adds § 307 to Title 53 of the Pennsylvania Consolidated Statutes, placing it within the existing preemptions subchapter that governs the limits of local legislative authority. Under § 307(a), no local government unit may impose or enforce any ordinance, resolution, regulation, or other measure that limits the number of individuals permitted to reside together in a single dwelling on the basis of familial relationship. This prohibition is absolute with respect to family-status-based restrictions and admits no local exception or variance. However, § 307(a) expressly preserves two categories of permissible occupancy limitation. First, local governments retain authority to enforce occupancy limits grounded in demonstrated health and safety standards, specifically including International Building Code standards, fire code regulations, and Department of Environmental Protection wastewater and water quality standards. Second, local governments may impose occupancy conditions required by federal, state, local, or municipal affordable housing program guidelines, recognizing that such programs often carry occupancy requirements as conditions of funding or eligibility. The bill supplies two operative definitions in § 307(b). 'Familial relationship' is defined as an individual's connection to one or more other individuals through blood, marriage, adoption, or foster care — a definition that is deliberately limited and does not extend to other relational categories. 'Local government unit' encompasses the full range of Pennsylvania municipal entities, including counties, cities, boroughs, incorporated towns, townships, home rule municipalities, optional plan municipalities, and optional charter municipalities. The act takes effect 60 days after enactment.
Key Points
- Prohibition: Local government units may not limit dwelling occupancy based on familial relationship [§ 307(a)]
- Permitted limitation: Occupancy caps based on International Building Code standards, fire codes, or DEP wastewater/water quality standards [§ 307(a)(1)]
- Permitted limitation: Occupancy conditions required by federal, state, local, or municipal affordable housing program guidelines [§ 307(a)(2)]
- Definition of 'familial relationship': Connection through blood, marriage, adoption, or foster care [§ 307(b)]
- Definition of 'local government unit': All Pennsylvania county and municipal entity types [§ 307(b)]
- Effective date: 60 days after enactment [Section 2]

Implementation
Implementation responsibility falls entirely on local government units, which must audit and, where necessary, repeal or amend any existing ordinances, zoning codes, or regulations that condition occupancy on familial relationship. The Commonwealth does not establish a dedicated enforcement agency, nor does it create a state-level complaint or adjudication mechanism. Enforcement will therefore occur primarily through litigation — affected individuals may challenge noncompliant local ordinances in state court, and local governments that fail to conform their codes within the 60-day window face legal exposure. The Department of Environmental Protection plays an indirect role as the source of the wastewater and water quality standards that define one category of permissible occupancy limitation, but the department is not assigned any new administrative duties under the bill. No funding appropriation accompanies the legislation, and no reporting requirements are imposed on local governments. The absence of a state enforcement infrastructure means that compliance will be uneven and largely reactive, dependent on affected residents or advocacy organizations initiating legal challenges against noncompliant municipalities.

Impact
The direct beneficiaries of this legislation are individuals and households whose living arrangements do not conform to traditional family structures — including unrelated roommates, communal households, intentional communities, and individuals in non-marital domestic partnerships. The bill also benefits multigenerational households that may include unrelated caregivers or extended family members not captured by narrow municipal definitions of 'family.' By removing family-status-based occupancy barriers, the legislation expands the practical supply of affordable housing by enabling more individuals to share dwelling costs without municipal interference. Local governments bear the primary administrative burden, which consists of reviewing existing codes and ordinances for compliance and making necessary amendments. This burden is modest for municipalities with modern, professionally drafted codes but may be more significant for smaller townships with older, less frequently updated ordinances. The bill carries no direct fiscal impact on the Commonwealth, as it creates no new programs, appropriations, or state administrative functions. The long-term expected outcome is a modest but meaningful increase in housing affordability and flexibility, particularly in high-cost urban and suburban markets where occupancy restrictions have historically been used to limit density and exclude non-traditional households. No sunset provision is included.
Legal Framework
The bill operates squarely within Pennsylvania's established framework of state preemption of local authority under Title 53. The Pennsylvania General Assembly possesses plenary legislative authority over municipalities, which are creatures of state law and hold only those powers granted by the Commonwealth. By adding § 307 to the preemptions subchapter, the legislature exercises its constitutional authority to define the outer limits of home rule and general municipal power, including the authority of home rule municipalities and optional charter municipalities that would otherwise enjoy broader local legislative discretion. The preemption is field-specific and targeted: it does not displace local zoning authority generally but carves out one specific subject — family-status-based occupancy limits — from the permissible scope of local regulation. The bill's structure also implicates federal fair housing law. The Fair Housing Act prohibits discrimination based on familial status in housing, and many family-status-based occupancy ordinances have been challenged under federal law. This state preemption reinforces and extends those federal protections at the state level, providing an additional, state-law basis for challenging discriminatory occupancy restrictions. The allowable exceptions for health and safety standards and affordable housing program guidelines are carefully bounded to ensure that the preemption cannot be circumvented through pretextual reliance on building or fire codes as proxies for family-status discrimination.

Critical Issues
The most significant implementation challenge is the absence of a state enforcement mechanism. Without a designated agency empowered to investigate complaints, issue compliance orders, or impose penalties, the preemption's effectiveness depends entirely on private litigation. Municipalities that are slow to update their codes face no immediate consequence beyond the risk of being sued, and residents in communities with noncompliant ordinances may lack the resources or awareness to pursue legal remedies. The definition of 'familial relationship' — limited to blood, marriage, adoption, and foster care — creates a potential gap. Domestic partners, cohabitating couples not legally married, and other relational categories outside this definition are not protected by the preemption's prohibition, meaning local governments could theoretically craft ordinances that target these groups without technically violating § 307. The health and safety exception, while facially neutral, presents a risk of pretextual enforcement. Municipalities opposed to the preemption's policy goals may attempt to use building code or fire code occupancy standards as a mechanism to achieve the same restrictive outcomes that family-status limits previously accomplished. Courts will need to scrutinize whether asserted health and safety justifications are genuine or serve as proxies for the prohibited family-status discrimination. Opposition arguments center on local control and community character — the traditional justifications for single-family zoning and occupancy restrictions — as well as concerns about infrastructure capacity, parking, and neighborhood density. Some municipalities may argue that the preemption interferes with their home rule authority, though this argument is legally weak given the General Assembly's established supremacy over municipal powers. Finally, the interaction between this preemption and existing affordable housing program occupancy requirements warrants careful attention, as the exception for such programs could create compliance complexity for municipalities administering multiple overlapping housing programs with varying occupancy standards.
