Wikidata lists Dalarö Tullhus as heritage-listed and gives 1788 as its founding or opening date. Its rooms are rented to companies, associations and private individuals for meetings, and for smaller social gatherings such as birthday, christening and funeral receptions. The venue says it does not run a regular banquet-hall business.

The larger rooms hold up to 50 people and cost from SEK 2,500 (about $241 or £191) per booking. Cups, glasses, plates and cutlery are included. Smaller meetings for about 10 people start at SEK 200 (about $19.3 or £15.3) an hour. Cleaning and washing-up may add to the cost. Renters must leave the room in the condition in which they received it, and can pay for cleaning and dishwashing services when booking.
