Enter an address or tap the map. You will see how the site is zoned, what the official code means and how high you may build.

Tap the map to see the zoning at a spot.
Zoning: City of Vienna (generalised land-use and development plan), CC BY 4.0
Zoning states what a plot may be used for. It decides whether you may live there, run a business there, or build at all, which makes it the first question before any purchase or change of use. The map groups the official classes into these categories:
An example: "GB Bauklasse III" means mixed building area, building class III, so up to four storeys. The map shows the code, the field next to it spells it out.
In Vienna the building rules sit in the same plan document. The building class caps the height (I to VI, plus special forms), the building type states whether closed, semi-detached or open development is allowed.
Both appear in the "Building rules" field wherever the plan holds them for that area. What exactly follows for a single plot is set out in the city’s plan document.
This page is guidance, not legal advice. The legally binding sources are the City of Vienna’s plan and plan document; for a building project only the authority’s statement counts.

For the same address we also show how loud, how warm and how well connected the location is.
Enter the address above and pick it from the list. The map jumps there and shows the zoning at that spot. You can also tap the map directly.
The land-use plan states what an area may be used for, the development plan states how you may build on it. Vienna combines both in one plan document, which is why we show zoning and building class together.
Usually only as a non-disruptive use and mostly on the ground floor. Hospitality is generally not intended in purely residential areas. What is permitted in an individual case is decided by the authority on the basis of the plan document.
No. We show the City of Vienna’s official open data in plain language. The plan and plan document are legally binding, and for a specific project the building authority’s statement counts.
Yes, through a procedure of the city council. Such procedures take time and only appear in the published map once they are complete. You should not count on an expected rezoning when buying.
