What is Della OS?

Della OS is a smart building operations platform developed to help multifamily property owners, managers, and technology integrators manage connected residential buildings through a unified system. The software integrates property management applications, building automation equipment, access control systems, resident services, and operational workflows across individual properties and larger portfolios. Its Della Connect interface provides centralized tools for managing residents, maintenance work orders, access permissions, building communications, and connected devices. Maintenance management capabilities support digital service requests, photo attachments, progress tracking, and synchronization with compatible property management systems. The Della Resident application allows tenants to interact with smart locks, adjust supported thermostats, receive announcements, reserve amenities, and manage visitor access. Della AI provides conversational assistance using building-specific records, including units, residents, connected devices, and access rules, to answer questions and perform permitted actions. Its AI workflows apply role-based permissions and validation controls while maintaining activity logs for operational oversight. Mission Control enables certified integrators to configure building technology, commission devices, verify installations, and maintain standardized deployments across different properties. Energy management capabilities integrate with compatible smart thermostats and environmental sensors to help operators optimize heating and cooling usage and monitor building conditions. Additional features include digital signage, automated resident onboarding, building notifications, approved vendor services, payments, and resident marketplace functionality.
