Alma Realty is a privately held real estate management and development firm founded in 1988 by Efstathios "Steve" Valiotis. The company operates from its headquarters in Long Island City, New York, with more than a dozen branch offices across the Tri-State area. The firm focuses on acquiring, owning, and managing multifamily, commercial, retail, and industrial properties throughout New York City and northern New Jersey. Its portfolio comprises approximately 146 properties totaling 7.4 million square feet with more than 6,700 residential units valued at $1.4 billion. The firm pursues a long-term ownership model supported by active property management and reinvestment in existing buildings. Portfolio composition includes multifamily walk-ups, mid-rise elevator buildings, mixed-use assets, and warehouse spaces distributed across neighborhoods in Washington Heights, Astoria, Murray Hill, Upper Manhattan, and throughout Queens and Brooklyn. Manhattan holdings represent roughly 37-42% of the portfolio by square footage and residential unit count, followed by Queens at approximately 30% and Brooklyn at 26-30%. Alma Realty maintains vertically integrated operations with professional staff handling leasing, compliance, maintenance, legal affairs, construction oversight, and tenant services. The company executes steady acquisition and redevelopment activity while selectively divesting properties where investor demand is strong. Notable projects include the Astoria Cove waterfront development in Queens, where the company partnered with Newark-based KS Group in September 2024 and secured $300 million in construction financing from S3 Capital in March 2025 for the first phase comprising 731 residential units. The project spans approximately 9 acres along the East River and is planned as a multi-phased development. George Sakellaris, founder and CEO of renewable energy corporation Ameresco, holds an investment stake in the company.
