The word is made up of 'Haus' (house) and 'eigen' (own). It literally means that something belongs to the 'eigenen Haus' (one's own house), with 'Haus' often standing for a company, hotel, or institution.

'Hauseigen' (in-house) is almost always used as an adjective before a noun. Predicative use (e.g., 'Der Wein ist hauseigen' — the wine is in-house) is rare and often sounds unnatural.

Common combinations are 'hauseigene Produkte' (in-house products), 'hauseigener Parkplatz' (private / on-site parking lot), 'hauseigene Bäckerei' (in-house bakery), or 'hauseigene Marke' (in-house brand). It often describes a special service or an exclusive offer.

own / peculiar
'eigen' and 'hauseigen' both have to do with belonging. 'eigen' is very general and can refer to a person or a thing: 'mein eigenes Zimmer' (my own room), 'deine eigene Idee' (your own idea). 'hauseigen' is much more specific. It means that something belongs to a particular company, hotel, publishing house, hospital, or similar institution, or is made there in-house. Learners may confuse the words because both express 'belonging to someone or something'. For personal possession, use 'eigen'; for offers or products of an institution, 'hauseigen' fits.
