Greenwich, Conn., Town Code ch. 5 § 5-30
Basement space; use
Operative Text
(a) No basement space shall be used as a habitable room or dwelling unit unless: (1) In every dwelling of three (3) or more dwelling units the ceiling height of the basement shall be at least eight (8) feet six (6) inches from the finished floor to finished ceiling; (2) In every dwelling of one (1) and two (2) dwelling units the ceiling height of the basement shall be at least eight (8) feet from finished floor to finished ceiling; (3) The floor and walls are impervious to leakage of under-ground and surface runoff water and insulated against dampness; (4) The window area is located entirely above the grade of the ground immediately adjoining such window area.
Greenwich Town Code ch. 5 § 5-30 establishes minimum conditions that must be met before any basement space may legally be used as a habitable room or dwelling unit. Buildings with three or more units must have basement ceiling heights of at least 8 feet 6 inches, while one- and two-unit buildings require at least 8 feet. Additionally, basement floors and walls must resist water intrusion and dampness, and all windows must be positioned entirely above the surrounding ground grade. Unless every one of these conditions is satisfied, the basement space cannot lawfully serve as living quarters.
Plain English — not legal advice.
Operators of residential properties in Greenwich should verify that any basement space offered or marketed as a habitable room or dwelling unit fully complies with each requirement listed in ch. 5 § 5-30 before tenants occupy that space. This means confirming ceiling heights meet the applicable threshold for the building type, ensuring floors and walls are properly waterproofed and insulated against dampness, and confirming that all basement windows sit entirely above the adjacent exterior grade. Maintaining documentation of these conditions—such as inspection records or construction specifications—is a practice commonly associated with compliant property management.

Under Greenwich Town Code ch. 5 § 5-30, tenants living in a basement unit have a right to occupy space that meets specific habitability standards, including minimum ceiling heights, moisture-resistant floors and walls, and windows positioned above ground grade. If a basement unit appears to fall short of these requirements—for example, showing signs of persistent water intrusion or having windows below grade—tenants may consider raising the violation with local housing or building code enforcement authorities. Tenant-rights organizations in Connecticut can help explain available options, including how a code violation might be relevant to housing complaints or other remedies.
