Residential Buildings & Homes
These are the bread and butter buildings of Mobile DayZ. Majority of loot found in these buildings will be food or drink items.
Police stations are high loot buildings usually containing 3 to 4 items. There's a high chance for guns and ammo to spawn here and a small chance to find a civilian tent.
Factories generally have a grab bag of items but usually include food, drinks, and helmets.
Town Hall or Government Building
The town hall building usually have decent loot with a chance to spawn guns and the rare civilian tent.
Churches usually have two or three items inside, often including food and drink. I haven't ever seen a gun spawn here.
Deer Stand or Guard Tower
While not technically a building, these deer stands do spawn items at their base. Deer stands normally show up in pairs so it's worth scouting around to find the second one. Deer stands have a pretty high chance to spawn guns.
These broken down buses actually act as buildings and provide a heat bonus when inside. Loot will spawn inside, usually a max of two items. It's a good place to find ammo and clothing.
Military Checkpoint Tents - Map One
These are the only military installments you will find on map/island 1. They are found at crossroads and are inhabited by four or more well armored military zombies. I generally avoid these unless well equipped. Some of the zombies that spawn here have guns (glock) and will shoot you. That being said, the zombies do drop ammo often and you can occasionally find a gun here.
Not a building but I included the crashed Humvee because it does have items that spawn near it. From what I've seen these items do not respawn. You can find the crashed Humvee on map/island 1 and on.
Military Bunk House - Map Two and Three
Great source for military gear and by map/island 2 you are usually geared enough to take them on and even if you are not I find it easier to outmaneuver the zombies here than those in the zombie checkpoints.
Military Building - Map Two and Three
Another great place for high end gear including the tortilla backpack (7 slots) and the mountain backpack (8 slots).
Military Compound - Map Three
Another great source of high end gear and easier to loot than the previous military buildings.
