MANHATTAN

Jeffrey Sosnick was first shown an apartment in his Central Park West building in 1982. The property was converting from a rental to the 227 Tenants Corporation, a cooperative. "The broker," he remembers, "said, 'Prewar — like pre-World War I!" As Sosnick — the co-op board president for 30 of the 31 years he's lived there — describes, "You feel like you're going into some European apartment house because of the design elements."

That's one reason the 20-unit building is part of the "Upper West Side-Central Park West" historic district designated by New York City's Landmarks Preservation Commission (LPC) — and one reason why a window-replacement project ballooned from a $400,000 budget to $571,000. On the one hand, that triggered the first special assessment in the co-op's history; on the other, it may have added compensatorily to its apartments' value.

The installation of new windows at the Central Park West co-op had ballooned in cost from $400,000 to $571,000, since the building is in a landmarked district and the windows had to be historically accurate. "The shareholders were mostly sanguine" about paying for the overage, says board president Jeffrey Sosnick, and everyone was happy with the results. "However," he adds, "as a result of all these additional costs it became necessary for the first time in our history to declare a shareholder assessment," for $70,000. "We had always prided ourselves on never spending more than we had."

Was the Landmarks Preservation Commission asking too much? Did the co-op want to cut corners that would harm the heritage of New York City? And where was the architect in all this? In Part 2 of our story about one co-op's dealings with the LPC, we offer an oral history describing the aftermath.

The co-op where I live, 5 Riverside Drive, is a wonderful place. A classic Art Deco high-rise designed by the team of Boak and Paris in 1937, the 109-unit co-op sits on the corner of 73rd Street and Riverside Drive. The shareholders love the proximity to Riverside Park and enjoy the wide vistas of the Hudson River. The building, which went co-op in 1966, has round-the-clock service and a live-in superintendent, laundry, storage and a bike room.

With those attractions, however, come challenges, as we learned when the real estate market took off. Ten percent of our apartments were sold within three years, many for between $1 million and $2 million. A number of shareholders submitted larger and more complex renovation plans than we'd ever handled.

It might not seem as big a dilemma as the need to replace windows or other big capital projects, but in terms of your apartments' market value and your building's first impression on visitors and prospective buyers alike, a dilapidated or out-of-date lobby can be a kiss of death — or at least a hug of disappointment. Yet as many board members know all too well, lobby renovation can be one of the most contentious and time-consuming projects in any condo or co-op board's tenure. It can seem like a task of unmanageable proportions.

But it's not. You simply need to do break it down into steps. Just make sure they're the right steps.
