139 East 79th Street, Manhattan

This is an unusually quiet pre-war co-op where the head officer was recently a seller.

A 15-unit, 1928 building on the Upper East Side. For a co-op, a clean city record means issues are handled by the board and managing agent, not that issues don't happen. The paper trail here is very thin, but it does show an active, high-priced market. Three things to know:

The head officer is also a neighbor — and a recent seller. The co-op's head officer, Michael Boublik, sold a unit here for $6.5M in April 2025. It's a sign of a resident-run board. This is an active building, with three sales over the last three years, all in the $5.7M–$6.5M range.

The building keeps its records clean with the city. There are no open housing-condition complaints or violations. A plumbing permit was issued in March 2025, suggesting routine work is being filed correctly. For a nearly century-old building, this lack of a city paper trail points to internal resolution.

Street life, not building problems, is what shows up in the 311 record. The handful of recent 311 calls from this address aren't about the building's operations. They are one-off reports on sidewalk snow, illegal parking, and outdoor dining, which is typical color for the Lexington Avenue corridor.
