633 Park Avenue, Manhattan

This is a pre-war Park Avenue co-op with a nearly spotless public record.

A 16-unit co-op from 1913, managed by Brown Harris Stevens. For a building this old, the city-level data is exceptionally clean. Co-ops resolve issues internally, so a quiet record points to a board that handles its business without needing city intervention. Three things to know:

The city's record is pristine. There are no open housing or building violations. No permits have been filed recently, either. For a building over a century old, this suggests a proactive board and a solid managing agent who stay ahead of maintenance and capital needs.

Units here trade between trusts and estates. Of the four sales in the last three years, three involved a trust or an estate. This is typical for this kind of building on Park Avenue and signals a certain kind of ownership culture.

Complaint logs are virtually empty. There has been only a single 311 call from this building in the last few years — one closed noise complaint. No housing-related complaints were filed with HPD at all. Residents are not using city agencies to solve problems.
