Bunkhouses are buildings in Tropico 3 and Tropico 4. Their quality is considerably better than shacks and shanties, being on par with poorly maintained tenements. Bunkhouses are also the cheapest form of housing that can be rented out to citizens. Their small maintenance cost means they can earn a profit even with a rent of $1/month. Bunkhouses are also very useful for filling in tight places with extra housing, as they're very slim and long, and hold a good number of people.
