The Clock Is Ticking: What NYC Developers Need to Know About the June 15, 2026 421‑a(16) Deadline

NYC residential developers are you ready for June 15, 2026? The 421-a(16) / ANYHP Completion Date deadline for NYC new construction projects is rapidly approaching (the date by which the NYC Department of Buildings must have issued a temporary or final Certificate of Occupancy for all residential areas / dwelling units).

All 421-a(16) projects with a Completion Date of June 16, 2026 – June 15, 2031 must have previously filed a “Letter of Intent” with NYC Housing Preservation & Development and committed to use a less generous 421-a(16) affordability option or else they will be ineligible for 421-a(16) benefits.

For additional insight on the 421‑a(16) Completion Date extension and its implications for developments, acquisitions, and financings, please refer to my prior blog post, available here.

If you have questions or would like to explore how the 421‑a(16) rules affect your development, acquisition, or financing, please reach out to me and my team at Rosenberg & Estis, P.C.  We look forward to helping you move your project forward.
