Della OS is an integrated smart building and property operations platform designed for multifamily residential communities and property management portfolios. The software unifies building automation, access control, resident communications, maintenance management, and connected device administration within a centralized system. Della Connect provides property managers with dashboards for monitoring building operations, managing resident information, processing maintenance requests, and coordinating staff activities. Its Della Resident application enables tenants to control compatible smart locks and thermostats, receive building announcements, manage visitors, and reserve amenities. The platform supports connected technologies such as HVAC systems, smart access devices, leak detection sensors, and building network infrastructure. Della AI uses building-specific information to answer operational questions, retrieve relevant records, and assist with authorized management tasks. Mission Control helps certified integration partners configure devices, standardize deployments, and manage connected building infrastructure across different properties. The platform also provides energy optimization, automated move-in and move-out workflows, digital signage, and a resident marketplace for booking services from approved vendors. Della OS integrates with property management systems including Yardi, Entrata, RealPage, ResMan, and AppFolio to synchronize information and support consistent operations across residential portfolios.
