Housing Cooperatives

A housing cooperative is a legal structure in which residents collectively own a corporation that holds title to a residential building or development. Rather than owning their individual unit outright (as in a condominium), each resident purchases shares in the cooperative corporation. Those shares entitle the shareholder to a proprietary lease on a specific unit and the right to vote on building governance.

Housing cooperatives come in three main forms. Market-rate cooperatives allow shareholders to sell their shares at whatever the market will bear — these are common in New York City's Upper East Side and Upper West Side, where apartment co-op boards are legendary for their rigorous buyer approval processes. Limited-equity cooperatives restrict resale prices to keep units affordable for future buyers; residents build modest equity but cannot profit fully from housing market appreciation. Leasing cooperatives (common in Scandinavia) own no property directly but lease from a property cooperative.

Sweden's HSB and Riksbyggen models demonstrate cooperative housing at national scale: over 500,000 homes are held in cooperative tenure in Sweden, with residents enjoying security of tenure, democratic governance of their buildings, and access to cooperative financing. In the United States, Co-op City in the Bronx — 35 residential towers built under the Mitchell-Lama programme — remains the largest cooperative housing development in the world, housing approximately 50,000 residents in 15,000 units.
