Storing guns in a garage is legal in Canada as long as you follow the same storage rules as anywhere else in the house. The problem is the climate. A garage can swing from minus 20 to plus 25 over a year, sometimes in a week, and every swing is a chance for water to condense on cold steel. Here is how to keep guns in a garage without finding rust in the spring, and what changes if the safe is in the basement instead.
Is storing guns in a garage legal?
Yes. The federal storage regulations say how a gun must be stored, not which room it is in. A non-restricted gun has to be unloaded. It has to be locked with a secure locking device, have the bolt removed, or sit in a locked container or room that can’t readily be broken into. And it can’t be readily accessible to ammunition unless the ammo is locked up. A restricted gun needs a lock fitted and a locked container, or a vault, safe or room built for it. A detached garage is held to the same rules. The full text is in the storage regulations, and our gun storage laws guide explains it.
Garages do get broken into, so bolt the safe to the floor or wall and keep it out of sight when the big door is open.
Why guns rust in a garage
Rust needs water on the steel, and in a garage that water comes from condensation. Steel changes temperature slowly. After a cold night, a mild damp day or an open garage door lets humid air in, and where that air touches the cold steel it drops below its dew point and leaves water behind. A car coming in covered in snow does the same thing as it melts. Inside a closed safe the effect is smaller, but any moisture that gets in stays there.
The concrete floor is the other source, and the one most people miss when storing guns in a garage. A slab can wick ground moisture, and a safe sitting right on it can rust from the bottom up.
Storing guns in a garage: the setup
- Get the safe off the concrete. A rubber mat or a pressure-treated base under it keeps the bottom out of the damp.
- Use an inside wall. An exterior wall is colder, and the steel next to it sweats first. Keep away from where the car parks too, since melting snow and road salt add moisture.
- Bolt it down.
- Put a dehumidifier inside. Most garages have no outlet near the safe, which rules out an electric rod, so use a rechargeable block. The Silent Dry Hypercube Large ($64.88) has a hygrometer on the face, so you see the humidity every time you open the door.
- Protect the steel. A thin coat of oil, plus a VaporTack SilentDry in the chamber of the guns you care most about ($24.99 for 5.56/.223, with other calibres too). Take it out before you load.
- No soft cases in the safe. They hold moisture against the gun.
- Keep the ammo somewhere steady. A garage that bakes in July and freezes in January is hard on ammunition, and gas cans and propane make bad neighbours. See how to store ammo.
Storing guns in a garage over the winter
- Check the hygrometer every couple of weeks and recharge the block when it sits above 50 percent.
- When you take a gun out to use it, carry it into the house in a closed case and let it warm up before you open the case. The water condenses on the case, not on the gun.
- When it comes back wet, dry and oil it before it goes back in the safe. Our guide to cleaning a gun after rain has the steps.
- Spring is the worst stretch. Thaw, rain and warm afternoons after cold nights mean more condensation, so check weekly in March and April.
Done this way, storing guns in a garage costs you a few minutes a month.
What about the basement?
A basement is steadier on temperature but damper. Many Canadian basements sit at 60 to 70 percent humidity from spring to fall, well above the 30 to 50 percent a safe wants. The same kit works: a desiccant block in the safe, oil on the steel, nothing soft inside, and the safe off a damp floor. A room dehumidifier helps everything down there, guns included. Our gun safe humidity guide has the numbers, and our dehumidifier picks cover sizing.
