Most safes are designed to bolt down, which gives you more security to your valuables. Bolting down your safe is not difficult. It can increase your safe's security and protection. But before moving your safe upstairs, there are issues that you must study and resolve. With this guide, we'll walk you through on how to bolt down a safe upstairs. We'll also share with you the reasons why you need to bolt down your safe. 

Weight capacity of floor upstairs

Detailed knowledge about floor wood structure is needed to assess the floor joist load capacity. You also need to understand the building code requirement for residential properties. However, knowing the basics will help you learn the current floor weight limits of your house. 

The local building codes state the smallest live load that floors require bearing. The International Residential Code specifies that floors must support 40lbs per square foot of live load The bedroom floor must handle 30lbs per square foot of the live load. 

A live load considers the weight factor a second floor can take. Live load is considered, such as furniture and people that the second floor needs to support. 

How to bolt down a safe upstairs

You may connect the safe to floor beams upstairs, whether they are wide or near together enough. A tape measure and stud finder allow you to pick these beams. 

Mark an area on the floor where you intend to mount your safe. Use a pen to label the mounting holes inside of the safe on the floor upstairs. That way, you know the spot where you can begin to drill. 

Installing a Safe Upstairs

Moving a safe upstairs requires careful planning and personal safety. You also need to make sure that the floor can support the safe's weight. Then you have to mark the holes of the safe on the floor, so you know where to drill. 

Fortunately, the process is simple. Most second floors can bear the weight of heavy safes. If the floor studs are wider than of the safe's hole, you can install the safe to wide sheet metal. You can now fit the sheet of metal and bolt the safe to the floor studs. 

However, we recommend consulting a skilled gun safe installer before bolting down your safe. Making sure everything suits your second-floor structure to prevent such damage to the house. 

You can follow these steps on how to bolt down a safe upstairs: 

  • Place the safe at the desired spot and mark the holes where you'll be drilling. 
  • Use a hammer drill to cut a hole on the floor. Insert the washers on top of the bolt before running it through the floor. 
  • Drive the bolts into the floor using a hammer. You can tighten the bolts with nuts to allow the safe to be anchored. 
  • Position the safe carefully on top of the holes where you placed the bolts. 
  • Put the plastic covering on top of the bolts inside the safe. 

The procedure to finish bolting down a safe is easy. But remember to take extra protection when drilling into the floor because you might get hurt yourself. 

Advantages of bolting down your safe

  • Bolting your safe is necessary for safety
    The wide and shallow safes tend to tip over if you don't bolt it down. The door weighs almost 30% of the total weight of the safe. A safe may tip over when you open the door of the safe. You don't want thick metal falling into your feet after opening the door.  It's foolish to spend hundreds of dollars to burglar-proof a gun safe but not spend $40 to bolt down a safe. 
  • Bolting down a safe makes it harder to open. The thickest part of the safe is the door.  Intruders will strike each five sides of the safe that are much thinner than the door.   
    It is difficult to strike a safe horizontally using a sledgehammer, or other heavy tools. It's dumb and risky to hit a safe while standing. But if your gun safe is not bolted down, attackers can position and swing down on it with brute force. 
  • Bolting your gun safe makes it harder to steal. No gun safe in the world can't be opened, given the right tools and enough time. Most burglars would carry out a safe where they can take their time and make all the noise they want to open a safe. That's why most burglars would want to steal a safe.  

    Remember that burglars will do anything to take out your safe even if they destroy your house. But if you bolt down your safe, whether it's mid-size or large safe, you added a layer of protection to your safe. 


Once you've picked and bolted down your safe, the work isn't hard. This will take you extra steps to protect your valuables and guns from theft. Remember to check your second floor's load limit before following these steps on how to bolt down a safe upstairs. It’s also advisable to consult a structural engineer to verify your floor's weight stability and integrity.
