The research shows that integrated systems are transforming multifamily property management through centralised visibility, automation, and data-driven operations.

Some of the key research findings from Parks Associates include:

• 20% average increase in operating efficiency from connected building deployments
• 18% reduction in operating costs through integrated smart building technologies
• 19% reduction in energy costs and 18% reduction in water costs with smart building systems
• 21% decrease in safety and security incidents among properties deploying connected building solutions

“Smart building technologies are evolving into core operational infrastructure for multifamily properties,” said Kristen Hanich, Sr. Director, Research, Parks Associates. “When access control, IoT signals, and property data are integrated into centralised platforms, operators gain real-time visibility and automation capabilities that improve safety, efficiency, and operational resilience.”

“Multifamily is moving beyond point solutions toward a more integrated way of operating,” said Dave Lillis, CEO of Door. “As these systems come together, operators can run their properties with greater clarity and control. Building Intelligence is what makes that possible.”

The research highlights access control as a core component within the broader Building Intelligence framework, connecting identity, device data, and property operations through centralised platforms. Currently, 70% of multifamily companies report deploying smart door locks in at least one property, rising to 91% among luxury properties, as operators implement connected systems to manage resident, staff, and vendor access across portfolios.

Available to download, the analysis draws on surveys of more than 700 apartment residents in US internet households and over 300 decision makers at multifamily property companies, supplemented by executive interviews conducted between 2024 and 2025.
