NYC Affordability

Unlike a condo, where an owner can generally rent out their unit freely, a co-op shareholder’s right to sublet is set entirely by the building’s own proprietary lease and house rules — and it’s rarely unrestricted. Most buildings require a minimum period of owner-occupancy (commonly one to three consecutive years) before a shareholder can sublet at all, then cap how long they can keep subletting once they start — a common structure allows up to two years of subletting within a rolling five-year period, with the clock resetting after that window closes.

Every sublet typically requires its own board application for the prospective subtenant — financial documents, references, sometimes an interview — similar in substance to a buyer’s board package, even though no sale is happening. Boards also commonly charge a sublet surcharge on top of regular maintenance, often in the 10-30% range, to discourage buildings from functioning like rental properties.

Worked example

A shareholder paying $2,000/month in maintenance subletting under a 25% surcharge policy owes an extra $500/month to the co-op while the sublet is in effect — on top of whatever rent they’re charging their subtenant — and can typically only do this for up to two years before needing the board’s case-by-case approval to continue, per a typical (though building-specific) policy. Always confirm the actual sublet policy in your building’s proprietary lease rather than assuming these are universal rules.
