Accessory Dwelling Units (ADUs) are secondary housing units on a single-family residential lot. ADU’s benefit homeowners, renters and the community by creating more housing options while maintaining the character of single family residential suburban and rural communities. For homeowners, a code-compliant ADU can provide additional source of income, flexibility for multi-generational housing, and an increase in property value.

CDCLI has been selected by New York State Homes and Community Renewal to administer the new Plus One ADU Program in the Town of Shelter Island. The Plus One ADU Program provides a full-service program to support low- and middle-income single family homeowner occupants who wish to:

• Build a new accessory dwelling unit on their property OR
• Improve an existing ADU that needs to be brought into compliance with code requirements.
