Under Mount Vernon Code ch. 149 § 149-9, operators of residential buildings—whether fully or partially occupied—are generally expected to maintain compliance with the code's occupancy, size, light, and ventilation standards at all times. Compliant operators typically conduct periodic reviews of their properties to confirm that all occupied spaces meet these requirements and that any accessory uses are applied consistently with the uniform definition established by this section. Keeping documentation of inspections and any corrective actions taken can support a record of ongoing compliance.
