Plus One Accessory Dwelling Unit (ADU) Program

ADU Program

An Accessory Dwelling Unit (ADU) is a small, independent residential dwelling unit located on the same lot as your home. The unit could be located within the existing home or could be a fully independent and detached structure. ADUs come in a variety of types, including basement apartments, attic conversions or in-law suites. 

ADUs can serve a number of different purposes providing housing to family members or serving as an added source of income for household expenses by renting an additional unit.

How Does the Program Work

ADU Program

The Plus One ADU Program will combine low or no-interest capital loans and construction financing grants provided by the New York State Homes and Community Renewal for up to 15 eligible homeowners to build or convert ADU’s on their property.

In partnership with Restored Homes HDFC, the program will provide homeowners with financial and technical support, including predevelopment and construction resources on a single-family property where the existing zoning allows for one additional unit. ADUs financed through the program will become safe, habitable, and potentially rent-restricted units that will help homeowners generate additional income and support long-term homeowner and neighborhood stability.

Eligible Homeowners

  • May earn up to 165% AMI or $186,450 for a two-person household. Preference will be given to homeowners who are at or below 100% AMI or $113,000 for a two-person household.
  • Must be owner-occupant
  • Must be current on any existing mortgages and not have outstanding municipal arrears or be in an active payment plan

Eligible Buildings

  • One-unit, single-family detached residential homes
  • Homes that allow for two-family construction under the existing building and zoning code
  • Homes must pass a housing quality inspection and need no major repairs other than repairs that are essential to the ADU construction scope
  • Eligible homes must either be free of housing or building code violations prior to receiving program financing, unless the violations are directly related to ADU, or the owner must agree to address all existing violations prior to ADU construction completion.
  • For basement conversions, the applicable ADU space must meet ceiling height requirements prior to conversion and must be located outside of the 2050 Stormwater Flood area as well as the 2100’s 100-year coastal flood zone.

The following ADU typologies may be eligible to participate in the program:

  • Attached or detached existing structures or newly constructed structures
  • Basement or attic unit conversions
