The County of Westchester Model Ordinance for Accessory Dwelling Units (ADUs) is a guide for other municipalities in the county to adopt (in part or in whole) to promote and regulate ADUs. The goal of ADUs in the area is to increase the housing stock efficiently, increase affordability, and provide smaller and more accessible housing options. The model includes ADU requirements such as eligibility, number of ADUs permitted, occupancy and use, creation, density, approval, application feeds and information, and design. Design requirements vary based on if the ordinance is addressing accessory apartments or accessory cottages.
