The **Real Estate Board of New York (REBNY)** is a pivotal trade association formed in 1896, originally named the Real Estate Brokers of New York and renamed in 1913. It serves as a leading organization representing New York City's real estate professionals, including brokers, owners, managers, builders, developers, law firms, banks, architects, and service providers[1][2][3]. REBNY's mission revolves around facilitating real estate transactions, promoting ethical industry standards, advocating for favorable public policies, expanding New York’s economy, encouraging property development and renovation, and enhancing the city’s attractiveness for business and residents[1][2][3]. Historically, REBNY has played a significant role in shaping New York City's real estate landscape. Early achievements include its involvement in the Westside Improvement Project, which led to the development of key infrastructure like the Henry Hudson Parkway and Riverside Park under Robert Moses' vision. During the Great Depression, REBNY focused on tax reductions, infrastructure support such as the 8th Avenue subway, and combating rent control measures that could harm the industry. The Board also established its research arm in that era, producing influential market studies on foot traffic, occupancy, and urban challenges[1]. Over the decades, REBNY evolved from a primarily commercial brokers’ alliance to include residential brokers and a broad spectrum of industry stakeholders by the 1970s, reflecting the diverse and complex New York real estate market[2]. Today, it operates more than 69 member-led committees that address issues like tax law, zoning, land use, and rental policy, shaping best practices and public policy[5]. The Board of Governors, composed of prominent industry leaders, guides REBNY’s strategic direction[5]. REBNY is also known for its professional education programs offering state-certified courses, continuing education, and seminars to elevate industry expertise. It maintains the Seymour B.
