Section 157-7 of Clarkstown's Code of Ordinances establishes the foundational vocabulary for the town's residential housing chapter, defining key terms such as "dwelling unit," "family," "habitable space," "multiple dwelling," and "exit," among many others. These definitions set the boundaries for how the rest of Chapter 157 is interpreted and applied to residential properties throughout Clarkstown. For example, the definition of "family" includes specific criteria for determining whether a group of four or more unrelated individuals qualifies as the functional equivalent of a traditional family, which affects how occupancy rules are applied.

Compliant operators pay particular attention to definitions like "dwelling unit," "multiple dwelling," and "family," as these terms directly shape occupancy limits and permissible uses of their properties.

Tenants living in Clarkstown should be aware that the definitions in § 157-7 of Chapter 157 shape many of the rights and protections that apply to their housing, including what qualifies as a lawful dwelling unit, what constitutes a proper exit, and how "family" is defined for occupancy purposes. The "family" definition in § 157-7 is particularly relevant for households of four or more unrelated individuals, as it outlines the criteria used to determine whether such a group may lawfully occupy a single dwelling unit together. Tenants who believe their living conditions or occupancy status may be affected by these definitions can consult local tenant-rights organizations or raise relevant provisions when responding to any enforcement action under Chapter 157.
