Housing law — New York
Statewide ADU mandates have not passed in New York; the action is in New York City, which legalized ADUs across much of the city and opened basement/ADU filings through DOB NOW.
NYC's 'City of Yes for Housing Opportunity' (adopted December 2024) legalized ADUs, cut parking mandates near transit, and enabled office-to-residential and transit-oriented development.
