What Quinlan Development Group does

Quinlan Development Group is a privately-held, family-owned real estate investment and development company headquartered in New York City, founded in 1971 by Robert C. Quinlan. The company develops, renovates, and owns real estate across multiple asset classes including mixed-use residential rentals, luxury condominiums, retail, self-storage, and commercial office properties, with a portfolio exceeding 3 million square feet across 36+ properties. Its holdings include more than 125 retail stores totaling over 400,000 square feet, concentrated primarily in Manhattan and Brooklyn, with growing exposure to New Jersey, Florida, Georgia, and Arizona markets.

The firm's business model combines ground-up development, redevelopment, and long-term ownership of physical assets, generating revenue through rental income, property sales (including condo sell-outs), and management fees. It vertically integrates property management and retail leasing through its wholly-owned affiliate Walker, Malloy & Company, Inc., which manages co-ops, condos, rentals, and retail buildings in Manhattan with 24/7 tenant services. Recent product expansion has been focused on self-storage facilities in New Jersey (six completed between 2019 and 2024) and industrial/warehouse assets in secondary markets. The company also offers construction loans, mezzanine financing, and acquisition bridge loans as a financing services line.

Day-to-day operations are led by second-generation principal Timothy C. Quinlan (who took over in 2007), supported by an institutional-grade team including Partner Tyler A. Wilkins (ex-DTZ Rockwood) and specialized heads of acquisitions, development, and asset management. The company employs between 11 and 50 people, makes substantial personal co-investments in its projects, and operates without external institutional capital. Its go-to-market relies on direct, relationship-driven deal sourcing, with project-specific websites deployed for tenant acquisition on major developments.
