Frequently Asked Questions
Can I build an ADU in New York City?
Yes, as of September 30, 2025. NYC's 'City of Yes for Housing Opportunity' zoning amendment, approved by the City Council in December 2024, allows ADUs in 1- and 2-family homes citywide. You can convert interior space (basement, attic, garage) or add a detached ADU in the rear yard. The owner must reside on the property as a primary resident. ADUs require NYC Department of Buildings permits.
What is the Airbnb law in New York City?
NYC Local Law 18 (2022), effective September 5, 2023, requires hosts to register with the city ($145/year), be present during all guest stays (no whole-home rentals when not home), and allows a maximum of 2 guests. Airbnb removed non-compliant NYC listings in September 2023. Violations carry fines from $1,000 to $7,500. This is one of the strictest short-term rental laws in the United States.
Do the ADU rules differ between NYC boroughs?
Yes. ADU applicability depends heavily on your borough and zone. Staten Island and Queens have the most single-family R1-R3 zones where detached ADUs are most applicable. Brooklyn and the Bronx have mixed zones. Manhattan has very limited single-family residential — most ADU activity there would be basement apartment conversions in brownstones. Additionally, the 152 Historic Districts add LPC review requirements that can significantly extend timelines in neighborhoods like Brooklyn Heights, Park Slope, and Harlem.
What is the City of Yes for Housing Opportunity?
City of Yes for Housing Opportunity is the largest zoning reform in NYC history, approved by the City Council in December 2024. It allows more housing types citywide including ADUs in 1- and 2-family homes, transit-oriented development near subway stations, Universal Affordability Preference (UAP) for affordable housing, and eliminates minimum parking requirements citywide. Most provisions took effect September 30, 2025.
