Compared to the 2001 census, the 2011 Register-based Census (reference day: 31 October) captured a plus of 144 568 buildings (+7.1%). The highest increase is located in the western Austrian Laender of Tyrol and Vorarlberg (each with a plus of about 10%), followed by Upper Austria (8.8%), Salzburg, Styria and Burgenland (each with a rise of about 8%). In Lower Austria, the number of buildings has risen on average (6.8%), in Carinthia the growth has been below average (6.4%). Only in Vienna, the total number of buildings has declined compared to the 2001 census, which is related to the number on non-residential buildings only.

The 2011 Census results show that since 2001, the number of apartment buildings has risen to a higher extent than that of single or double family homes. In the federal province of Burgenland this difference can be best observed. Here, the number of residential buildings with three or more dwellings has increased by 76% from just under 2 000 to approximately 3 500 in 2011. However, the percentage of apartment buildings is still the lowest among all federal provinces of Austria.

The ownership structure of the buildings depends very much on the type of the building. Residential buildings, hotels and similar buildings, buildings for wholesale and retail trade and buildings for manufacturing and storage are predominantly owned by one or more than one persons. Buildings for public entertainment, education and health care predominantly are in possession of the public sector and other public bodies. The ownership structure of buildings for traffic and communication is characterized by similar proportions of buildings owned by private persons and companies whereas in case of office buildings the percentage of private-person owners outweighs the percentage of companies as owners. Buildings designed for institutional households have the most heterogeneous ownership structure.

Approximately one building in seven was erected before 1919. In the period between World War I and II and during the Second World War fewer buildings were built, only about one in 13 originate from the years 1919 to 1944. The distribution of the buildings erected after 1944 does not show significant fluctuations. The largest proportion was built during the years 1971 to 1990 (28.8%). One fourth of the buildings was constructed after 1990, about as many as in the period between 1945 and 1960. In Vienna, the inventory of older buildings (erected before 1945) differs significantly from that of the other federal provinces. One fifth of the buildings was built before 1919, another 15.2% in the years between the two World Wars and during World War II, respectively.

The proportion of old buildings is higher for apartment buildings than for single or double family homes. It is highest among non-residential buildings which are designed for public entertainment, educational and health care purposes.
