As the New York City development community awaits a possible extension of the Section 421-a completion deadline, developers can still preserve, and even increase, the value of their asset in the event no such extension is granted.

A New Path for Unfinished Portions of Section 421-a Projects

The deadline for completing construction for Section 421-a real estate tax benefits is currently June 15, 2026. However, developers who will not be able to timely achieve that goal may be comforted to learn that Seiden & Schein, P.C. offers an alternative solution if a Temporary Certificate of Occupancy for all residential apartments has not been issued by that date: Apply for 421-a benefits for the completed section and create a for-sale condominium for the incomplete section of the building.

Maximizing Development Potential

By converting the residential apartments that will not be covered by at least a Temporary Certificate of Occupancy on or before June 15, 2026 into for-sale condominium units, developers can open doors to new markets and transform a timing setback into new possibilities for recovery of capital, all while maintaining Section 421-a eligibility on the residential rental apartments that were completed in accordance with the time requirements of the Section 421-a program.
