The answer to “Can a gun safe be kept in a garage” is still in debate. but in our point of view, you shouldn’t do that.

Why Shouldn’t You Put A Gun Safe In An Unheated Garage?

A Gun Safe


Moisture is an important factor, which prevents us from storing a gun safe in an unheated garage. It is usually where less sunlight comes in and isn’t completely insulated.

Especially melting snow from car tires or running appliances in a cold garage without proper ventilation creates excess moisture. The seasonal changes also affect humidity levels.

Such a natural condition of the unheated garage makes it an unsuitable place for your firearm. High moisture buildup inside the gun cabinet will result in rust, a harmful factor to ruin all kinds of guns.

The Thief Risk 

The thief risk is another concern, which is as important as high moisture. The garage is the place where family members often go in and out every day. As being frequently opened, it is the easiest place to catch the attention of outsiders.

In modern life, we rarely think about robbery risks. But the fact that the strangers’ curiosity about the giant stack of guns can go over what we usually think about.

Besides the ease of scouting the garage, robbers can break the emergency release to enter the garage. If putting a gun safe there, they can easily use the car or a tow strap to bring the firearm out. So, a high thief risk always exists if you choose the garage.

Fire Risk 

Many of us usually store the household and vehicle accessories in the garage. If flammable items such as batteries or appliances are close to gasoline, oil, and paint thinner, it would cause a fire.

On the other hand, many people love to turn the garage into a home workshop. That is why the potentiality of overloading electricity by using many appliances and tools simultaneously is another fire risk.

Due to the major factors explained above, it is hard to answer “Yes” for the question can you have a gun safe in the garage?

What If A Garage Is The Only Place You Have?

Keeping the gun safe in the garage should be the last choice if you find it difficult to find another safe spot. You can still leave it there as long as the temperature and safety conditions are well controlled.

It is not bad to place the gun safe in the garage at a tight house. The most concerning factor is how to maintain the ideal temperature. The storage room’s temperature is 70 degrees Fahrenheit and 50 percent of relative humidity.

In most cases, we don’t have such an ideal room. So, to safely protect your valuables and weapons, it is necessary to set up a dehumidifier or pointing lights inside the safe.

Cope With Humidity

Some kinds of liquid like oil, cosmoline, or silica gel also help minimize the humidity level inside your safe and maintain a higher temperature than the outside.

  • Never put flammable things near the safe.
  • Install the heat alarm to alert once the high rise in temperature inside.
  • Plug one appliance into one outlet.
  • Don’t use the extension cords to avoid overheating.

The bedroom and basement are two places we recommend if you are searching for the best places to keep the gun. If you have a small collection of guns, put them into a nightstand gun safe or inside the closet, then bolt it down to the floor.

The outweigh of the basement is the capacity of bolting the safe into the ground easily. Furthermore, the basement is usually out of the burglary’s interest. However, at the same time, you still need to install a dehumidifier to control the moisture inside the safe.
