One platform for Hausverwaltung and smart building operations in Austria
Unitify connects access control, video intercoms, smart meters, dispatching and a resident app into one system, and keeps the building documentation a Vienna Bauwerksbuch needs in order as it goes, rather than reconstructed under deadline pressure.
Built for how a Hausverwaltung actually runs a building
Under the Wohnungseigentumsgesetz 2002 (WEG 2002), owners of a building form an Eigentümergemeinschaft, and a Hausverwaltung (Verwalter) is appointed to run day to day operations on the community’s behalf: collecting Betriebskosten, maintaining the building, and organizing the Eigentümerversammlung.
In Vienna specifically, Section 128a of the Bauordnung für Wien (informally referred to in the industry as Paragraf 128a WBO) requires a Bauwerksbuch, an ongoing electronic record of a building’s structural condition, for new buildings, additions and larger conversions, and on a phased deadline for older buildings. Unitify is built to keep that record current as part of normal operations instead of a one-off compliance project.
Payment rails already in use
Betriebskosten collection runs on the payment method Austrian owners already use for recurring bills.
SEPA-Lastschrift
The standard direct debit rail for Betriebskosten across the EU’s SEPA area, which includes Austria. Owners authorize a mandate once; collection then runs automatically each period.
SEPA-Überweisung
Standard bank transfer for owners who have not set up a direct debit mandate, or for one-off charges.
Built around Austrian building law, not around it
Every claim below links to the primary or official-source citation it is verified against, not a summary.
Bauwerksbuch obligation (Section 128a Bauordnung für Wien)
Vienna’s building code requires a Bauwerksbuch, kept electronically and registered in the city’s online Bauwerksbuch database since 1 July 2024, before the completion notice is filed for new buildings, additions and conversions, and on a phased deadline for existing buildings. The law names three exemptions: Kleingartenhäuser and Kleingartenwohnhäuser (garden houses) and buildings with a built-up area of 50 square meters or less. This is a Vienna city building-code provision, not a nationwide Austrian law: it applies within the city and does not extend automatically to other Austrian states.

Buildings erected before 1 January 1919 must have a registered Bauwerksbuch by 31 December 2027; buildings from 1 January 1919 to 1 January 1945 by 31 December 2030. Buildings from 1945 to 2014 that have had no approved conversion since are not currently required to create one for the first time.

Intercom, access, video, meters and EV charging connect through mini apps, alongside your requests and billing.
Digital intercom
Calls go straight to the resident’s phone. Entry by app, BLE tag or face.
Access control
Contactless entry by phone or tag. Vehicle access by plate recognition.
Video surveillance
Live cameras, digital archives and plate recognition at the gate.
Meter telemetry
Electricity, water, gas and heat readings arrive automatically, no manual rounds.
EV charging
Stations on the map, sessions booked, billed and tracked in the app.
Building management
Ventilation, heating, lifts and other systems monitored from one dashboard, with instant alerts.
Devices, orchestrator, resident app
Devices
Intercoms, access control, cameras, meters, EV chargers and building systems, from any vendor.
Orchestrator
Unitify connects every device to one dashboard. New hardware plugs in as a mini app, nothing gets replaced.
Resident app
One app for doors, meters, intercom calls and charging. No fifth login to remember.
Questions Hausverwaltungen ask
Was ist ein Bauwerksbuch?
An ongoing electronic record of a building’s structural condition and maintenance history, required under Vienna building law so the city and the owners have a current picture of the building’s state rather than reconstructing it from paper files when something needs checking.
Ist eine virtuelle Eigentümerversammlung zulässig?
Under WEG 2002, an Eigentümergemeinschaft can pass resolutions in writing (Umlaufbeschluss) without a physical assembly if the required majority agrees in that form; whether a fully virtual assembly format is available follows the community’s own rules and the Verwalter’s process, not a single blanket provision comparable to Germany’s 2024 virtual-assembly rule.
Für welche Gebäude gilt die Bauwerksbuch-Pflicht?
New buildings, additions and conversions within Vienna, before the completion notice is filed, under Section 128a Bauordnung für Wien. The law exempts Kleingartenhäuser, Kleingartenwohnhäuser and buildings with a built-up area of 50 square meters or less. It is a Vienna city rule, not automatically applicable in other Austrian states.
Bis wann muss ein Bauwerksbuch für Altbauten in Wien erstellt werden?
Buildings from before 1 January 1919 by 31 December 2027, and buildings from 1 January 1919 to 1 January 1945 by 31 December 2030, registered electronically in the city’s Bauwerksbuch database.
Was ist eine Eigentümergemeinschaft nach dem WEG 2002?
The community formed automatically among the owners of a building once more than one unit exists, which decides on shared matters and appoints a Hausverwaltung to run day to day operations on its behalf.
