Case Study: SL Green Realty Corp. achieves a best-in-class tenant experience across New York City with Building Engines

How SL Green Delivers a Best-inClass Tenant Experience Across New York City with Building Engines

SL Green Realty Corp., New York City’s largest owner of Manhattan office space with over 23 million square feet across 30 buildings, faced a major operational challenge: managing roughly 75,000 tenant service requests a year while meeting the high expectations of marquee tenants. Their previous property management system was difficult to use, slowing teams down and generating user complaints, so SL Green needed a streamlined, tenant-focused solution to improve speed and reliability.

SL Green implemented Building Engines’ unified operations platform—including a web tenant portal and a customized mobile app—to handle work orders, inspections, preventive maintenance, broadcast messaging, and analytics. The platform improved response and completion times, drove strong tenant adoption, and delivered measurable outcomes: 94% tenant satisfaction, 98.6% work-order completion, 97.94% inspection completion, and 94.25% preventive-maintenance completion, while giving the company better transparency and accountability.
