The Mamdani administration announced March 18 the launch of new tools to help homeowners construct an ancillary dwelling unit (ADU) on their property, including several pre-approved plans and a reopened financing program.
Under the major zoning reforms collectively called City of Yes for Housing Opportunity, adopted in Dec. 2024, the city cleared the way for owners of one- and two-family homes to add a small extra unit to their property, such as a detached “tiny home,” a unit built above a new or existing garage, a unit attached to the home, or an attic or basement apartment — all of which create an extra home while maintaining neighborhood character.
