Can be set to 'true' or 'false' and determines if this is a 'passive' house for the purposes of multiplayer games. A passive house is one that the game uses for firing triggers, events and actions as each must be attached to a house. Passive houses can also be used to place objects on the map (such as neutral structures like Tech Buildings) as each object must belong to a house. Note that if this is set to 'true' then you must also ensure that Multiplay= is also set to 'no' (and vice versa) otherwise you may get Internal Errors - a house should not exist as both.
