Last updated: August 2026
A neighbourhood (Grätzl) in Vienna's 23rd district. Strongest on Air quality and Green space, while Quiet is more of a trade-off.
The Alterlaa residential park shapes daily life here, with its striking terraced blocks and plenty of green in between. Much happens outdoors, from the communal gardens to the paths between the buildings. It doesn't always stay entirely quiet, though.
The streetscape is almost solidly Gründerzeit apartment houses.
The six dimensions
Light & built form
Erlaa is densely and tall built — light falls narrow between the facades, and the lanes turn shady earlier in the day. Measured at the Grätzl centre: about 12.8 hours of direct sun on the longest day, about 4.8 in December. In the evening the sun disappears early behind the buildings. How bright a single flat is comes down to floor, orientation and courtyard vs. street side — the measurement is for the Grätzl centre.

Where is Erlaa?
Erlaa is in Vienna's 23rd district (Liesing), postal code 1230.
How safe is Erlaa?
Safety in Erlaa: Excellent (8.5/10), based on official police crime statistics. A non-binding orientation value for the area, not a statement about any single address.
Is Erlaa dangerous?
Short answer: no — Vienna consistently ranks among the safest large cities in the world, and that holds across all 23 districts. Erlaa sits at 8.5 out of 10 on the safety dimension (Excellent). One thing worth knowing when reading such figures: crime statistics count offences where they HAPPEN, not where those affected live. Districts with major stations, nightlife and many visitors therefore collect more reports without a residential street a few corners away being any different. Within a district, the gap between a busy hub and a quiet side street is usually larger than the gap between two districts.
How good is public transport in Erlaa?
Public transport in Erlaa: Excellent (8.5/10) – based on proximity to metro, tram and bus (Wiener Linien).
Is Erlaa noisy?
Quiet in Erlaa: Average (6.1/10), based on traffic-noise exposure. Part of the area sits along Altmannsdorfer Straße; a few streets further in it gets noticeably quieter. Right there, traffic drowns out a conversation with the window open (calculated above 75 dB by day). At night it calms down noticeably — the level drops below the threshold at which mapping begins. The busiest named axes nearby, by official annual traffic volume: Altmannsdorfer Straße (~80,901/day), A23 (Südosttangente) (~63,394/day), Sagedergasse (~24,692/day).
How hot does Erlaa get in summer?
In summer Erlaa is moderate — cooler than the Vienna average. Heat index 49 of 100 (Vienna average 57), modelled. Green cover, trees and open, low building form let the night cool down. This is a MODELLED index (from building form, density, green space, street trees, water and elevation, checked against the City of Vienna's climate analysis map), not a measured temperature and not a count of hot days. Within one area it varies a lot: a green courtyard and a treeless street a few metres apart are not the same place.
