DOOR, formerly Latch, has hardware on the doors of many apartment buildings. Della OS connects those locks to the lease, the resident app and the rest of the building.

Access is issued at move-in and revoked at move-out, automatically.
Unit, building and amenity doors in the Della Resident app.
Existing DOOR locks, including those installed as Latch, join the same Della standard as the rest of the portfolio.

Owners don't have to replace working locks to run every building the same way, even when different properties use different hardware.
No, you don’t. That’s the beauty of the DOOR and Della partnership: the DOOR hardware already installed at your property, including equipment installed under the Latch name, keeps working for you, now connected to Della OS. Planning a retrofit or a new building? You can also install new DOOR products and run them on Della OS from day one.
Della OS connects to Yardi, Entrata, RealPage, AppFolio and ResMan, so changes follow the lease in the system your team already uses.
Della OS connects property management systems, access control, smart locks, climate, Wi-Fi, cameras and more, so every building in a portfolio runs the same way, whatever hardware it already has.
