Free, openly licensed housing-market data for every Luxembourg commune: our own asking-price aggregates from active residential listings, together with the backfilled official time series published by the Observatoire de l'Habitat. Release 2026.08, in Parquet and CSV.
Every table is published in both formats. Parquet preserves the column types and is what you want for analysis; CSV is there so the files open anywhere. Browse the dataset on Hugging Face.

Latest sale and rental asking-price aggregates computed from active, catalog-visible residential listings, with labelled official cross-references. One row per Luxembourg commune, including communes with no publishable sample, so absence is explicit rather than silent.
32 columns · ChatHome active-listing corpus; official_* columns from Observatoire de l'Habitat / STATEC.
Registered-transaction sale prices per commune and quarter from the Luxembourg land registry, as published by the Observatoire de l'Habitat. Suppressed cells are kept as rows with null prices and a stated suppression rule, so a gap is never mistaken for a zero.
19 columns · Observatoire de l'Habitat — Ministère du Logement (Publicité Foncière), via data.public.lu.
Advertised rents per m² per month by commune, quarter, property type and dwelling-size bracket. The size bracket is part of the key: collapsing this series to one row per commune silently keeps an arbitrary slice, which is the most common way it gets misread.
9 columns · Observatoire de l'Habitat — Ministère du Logement (advertised rents), via data.public.lu.
Advertised (asking) sale prices per commune, property type and calendar year. Unlike the registered-transaction series this covers houses as well as apartments, because an asking price needs no cadastral surface.
16 columns · Observatoire de l'Habitat — Ministère du Logement (prix annoncés, with IMMOTOP.LU), via data.public.lu.
The commune dimension every other table joins to: identifier, names in the five ChatHome locales, and canton. Published so a reuser never has to guess how two tables line up.
7 columns · ChatHome commune registry.
The Lorraine communes ChatHome treats as the French cross-border residence belt, with the priority tier and commute corridor assigned to each. This is GEOGRAPHY, not prices. No cross-border price series is published, because none has been ingested — cross_border_source_status says exactly why, per country.
10 columns · French official commune registry (INSEE codes), enriched with ChatHome frontalier priority and corridor assignment.
Why this dataset carries no French, Belgian or German price series yet: one row per evaluated official source, with its reachability, licence, finest geography and the specific obstacle. Publishing the gap is more useful than publishing a silence, and it lets a reuser judge whether the missing country matters for their question.
11 columns · ChatHome evaluation of the official Grande Région statistical publishers.
