NEW YORK CITY

From their inception, housing co-ops have had procedures for screening — and interviewing — prospective shareholders, to ensure that they would be able to meet their financial obligations to the cooperative and that they understood and would meet their responsibilities to the community: to be good neighbors and to take part in the running of their cooperative. Provided that the co-op board doesn't discriminate against protected categories, it has the right to reject a prospective purchaser. This process helps populate a cooperative with individuals committed to participation and cooperation.

UPDATED 4:04 p.m. — A New York City bill requiring that landlords, including co-op boards and condo associations, disclose their anti-smoking policies to residents and prospective renters and buyers was introduced at an April 18 City Council meeting and forwarded to the Committee on Housing and Buildings for discussion.

The bill, Intro. 0833-2012, was not placed on the committee's agenda either for its meeting yesterday (April 30) nor its meeting tomorrow (May 2). Committee chairperson Erik Martin Dilan (D-Brooklyn) is the bill's chief sponsor, with five Council co-sponsors, all by request of Mayor Michael Bloomberg.

In December 2009, the New York City Council amended the administrative code to require owners of real property to submit a report to the city, benchmarking the energy and water efficiency of buildings. This was part of four legislative components known as the Greener, Greater Buildings Plan designed to increase energy efficiency and reduce carbon emissions from New York buildings. These laws require annual energy efficiency benchmarking that will be disclosed to the public and mandate a set of energy-efficient upgrades. The first component of these laws is known as Local Law 84 of 2009, which requires the benchmarking of buildings. This is probably the law your friend was referring to in your conversation.

An estimated more than 900 co-op shareholders and condo unit-owners gathered at a Queens forum and an adjacent movie theater's simulcast on April 12 to protest what they and politicians call an inequitable property-tax system, which taxes co-ops and condos at a far higher rate than any other residential property.

... the Sheffield condominium's male prostitute is getting evicted, but not for, like, a month, and there's visiting-dog trouble at a Riverdale co-op. For co-op and condo boards, we have another case of going out of your way to make life hell for older residents, and an expert says a co-op board president can let his cousin sublet longer than other shareholders can.

As a native Californian, Scott Miller says recycling is in his blood. So, it made his blood boil whenever he would see plastic laundry detergent jugs tossed into the trash bins in the laundry room at his Lower East Side co-op.

"The recycling area was just around the corner, but without signage and without an opportunity to make it easy to recycle in that area, it was all just going into a landfill," says Miller, who lives at the 1,728-unit Seward Park Cooperative.

It was one of the things that led him to volunteer last summer to take part in the Apartment Building Recycling Initiative, a two-hour program offered monthly by the city's Department of Sanitation (DSNY). There he learned about quick and often free fixes that can increase the amount of recycling and ensure that the proper things are going into recycling bins.

Committees are an invaluable tool in condominium associations and cooperative housing corporations, where it can be hard to get enough volunteers sufficiently capable of dedicating the time, attention and skills required to serve on the board. As well, since it's often effective to have a small board, having committees can extend the board's reach, ability and effectiveness. This allows the benefits of a smaller board without sacrificing the distribution of workload that comes with a larger board.

"Noise complaints are the bane of our existence," says Maryann Caputo, president of Tribor Management, which manages some three dozen co-ops and condos, mostly in Queens. "I'd rather have any problem other than a noise complaint."

They may be intractable, but noise complaints between neighbors are not insoluble — provided condo and co-op boards understand the nature of the quagmire they're getting into. And how to get out of it.
