The city of Beregost is full of generic homes which do not serve much purpose in the overall story. This list contains information on any home not already named in-game or without a central defining occupant who owns the house (e.g. Firebead's Home, Mirianne's Home, etc.).
One convenient method of differentiating between these homes is referring to them by their internal area codes as defined by the game's developers.
Unless otherwise specified, assume that NPCs carry nothing, containers are unlocked, and that NPCs will call the Flaming Fist if they witness the party looting their containers. Locks all have a specific difficulty class for a thief to be able to open them, referred to here as the lock's DC.
