Common house (Megaton)

The Common House located in Megaton contains food and alcohol that you can loot without obtaining bad Karma. Several Megaton Settlers can be seen sleeping in beds which, if you sleep in, will get you bad Karma. The Common House was created by the Megaton "government" to house transient Wastelanders and potential citizens. While most residents of the Common House work in Megaton and receive rations of food and water, they are not technically citizens as they do not own a home within the settlement.

The only good loot one could grab in here would be from anyone they pickpocket. In the Common House itself there is a large supply of food and a few beverages. In the fridge is a nuka-cola just incase you are doing The Nuka-Cola Challenge side quest.
