Should developers be required to set aside a portion of new apartments for middle-income residents?
The residential development at 263 Prospect Avenue in Brooklyn is nearing completion, though it currently lacks a certificate of occupancy. The project includes 144 total apartment units, with 20 to 30 percent reserved for middle-income households.
Why it matters
The development represents a significant addition to the area, built on the site of three former 19th-century townhouses. It utilizes the expired 421-a tax program, and the owner reportedly faces active litigation regarding alleged unsafe working conditions.
The building features 180 parking spaces, with two-bedroom units slated to rent for $4,738 monthly. Qualifying households of three earning up to 130 percent of the Area Median Income, or $198,510 annually, are eligible for the restricted units.

The Home Front
The project represents a continuation of high-density development patterns facilitated by the expired 421-a tax break program. This site reflects broader trends in New York City where developers transition from smaller residential townhouses to large-scale apartment complexes.
Prospective renters should monitor the official municipal records to confirm when a certificate of occupancy is granted before committing to a lease. Researching the status of building permits and safety records through city portals can provide helpful context for new developments.
The takeaway
Large-scale residential projects require a certificate of occupancy to ensure the safety and legality of a building before move-in. Always confirm that a property has obtained all necessary municipal approvals before signing a lease or providing a deposit for a new unit.
