A gun safe is an important part of your security system. If you want to be sure that the firearm you own won’t fall into the wrong hands, you need to keep it in a safe place.

There are countless reasons to invest in a gun safe.

Whether you want it for home defense, to protect your firearms from an intruder, or as a place to store your collection, there are lots of good reasons to purchase one.

People who want to build a gun safe in their homes can choose from two basic options.

They can either buy an existing model or build their own from scratch.

Buying a pre-made gun safe may be the best option for many people, but it’s not the only one. You can also do it on your own following some guides.

Building a gun safe in your closet is not very complicated if you stick to these instructions.  In short-

pick a closet.

-Prepare the inside part by cleaning and making room for guns.

-Attach doors, shelves, lighting, security, dehumidifier, and

-Finally, Install it wherever you want.

If you’re ready to take on the challenge of building your own gun safe, here are some elaborated tips that will help you get started.

Can I turn A Closet Into A Gun Safe?

If you have a closet in your home, it may be possible to turn it into a gun safe.

However, the area would need to be quite large so that you can properly fit all of the things, such as firearms and ammunition inside.

It would be best always to make sure that there’s no way an intruder could get inside your gun safely, so putting obstructions in this space will help you achieve that.

Ensure that there’s also only one way in and out for any intruders trying to get at your stuff if they enter through this space unscathed!

And lastly, doing some length measurements is the only way to ensure that everything can fit there!

Can You Store Guns In A Cedar Closet?

Cedar closets, on average, have a relatively high moisture content level.

They’re not as dry as other kinds of furniture, which can sometimes put people off from using them to store their guns because the weapons may rust faster than expected.

However, this type of wood is also known to be incredibly durable over time.

That means you still think about the damage humidity could do with your items, even if it does corrode things a bit.

There’s a reason why wood gun safes have been in vogue for so long, and it has nothing to do with moisture levels!

However, there is an alternative way that you can use to get rid of the moisture issue. You can use an electric dehumidifier or desiccant dehumidifier.

What Does It Take To Make A Gun Safe Out Of A Closet?

1. Main Structure

The common method for making a closet gun safe is the front module and its door.

Then you attach them to either side of your existing structure, like shelving inside the closets themselves, as building blocks roughly 30 inches apart on each wall (measuring from center-to-center) with an end piece at one end that’s attached to both ends roughly 30″ across.

This makes up your internal frame though this space to be reinforced for strength to ensure the welds are adequate.

2. Clean-ups

Then put floorboards down and any other materials such as paint or stickers on top of this, along with a lock your family will only use once it’s set up properly, which is good enough until you need more space later.

3. Security systems

The best way to secure it with a very strong and defense level lock or multiple locks is by having the door slide under the closet so you can either put hasps overtop it.

This requires an extra bit of space but would still be plenty large enough for your weapons and ammunition as well as concealing them from prying eyes, then putting any other padlocks on there for extra safety.

4. Closet unit

Unless you have excellent measurements of your existing closet, including depth, width, and height, then it’s probably best to get the whole unit rather than rely on the size being an issue.

if not, make sure everything fits inside with its necessary hardware needed for assembly, along with any special doors or hinges that might need to be customized in order for it to operate smoothly

And if you’re clever enough, learn about printing out 3D models for things such as hinges, shelves, and other necessary things.

5. Mobility

Depending on whether this is going to be a part of your day-to-day routine, office work, and so forth, where people will need to access those firearms will play a role in how safe it is or if you have them as an extra defense to keep the bad guys at bay.

Either way, so long as they’re not mobile and can be locked up properly, along with being sturdy enough for rough handling-which cannot happen that often anyway-then you should be fine.

6. Maintenance Cost

Cleaning, maintenance, and repairs tend to make the most monetary worth increase over time, like for gun shelves or cabinets, which is usually around 2 – 5% per year with this compared to storing your guns in the extra tool shed out in the backyard where you are generally less concerned about it needing repairs since they’re both being under higher risks of human activity.

It can be estimated that gun safes have a life expectancy well above ten years if cared for properly with regards to dust and humidity, decay and decay, soil buildup.

So good quality materials are required, especially if it’s going to be in a dry environment or will have greater use.

7. Material

The most important thing you need in this aspect is good sample measurements that give the gauge size (meaning how thick an object is) and length measurements.

You can then get awesome custom-made items from your contractor or maker to get exactly what you need for your guns and ammunition.

Either way, if you have the skill then you can do that on your own.

8. Maximize Space

I think that this gun safe is about as easy of an install considering you already own the full-size cabinets and do not have to buy anything extra, which is a plus.

But assuming you cannot fit them in, I mean, if there are many shelves, it can get ugly really fast at fast inspection and work on them regularly, so please do not gamble that the safe only needs one inspection before being used for actual storage purposes.

If only one shelf is needed for your guns, you can simply do each of them without going through the entire cabinet.

One thing I noticed while putting together. What I felt was that four decent-sized shelves did get very cramped real fast.

So if you end up needing more than one shelf that’s going to happen throughout the years, you had better have some extra space available.

How To Build A Gun Safe In A Closet? (With 7 Step)

1. Measure the space throughout your entire house to make certain you can fit your closet gun safe where you want it.

2. Try fitting several of the same size gun safe into different spaces – this will help optimize free space and ensure that they’re all compatible with one another.

3. Show the room of your choice to a safe company and explain what type or style of gun safes you’ll be needing; they may offer customization such as different mounting brackets inside your closet (or even pre-built systems, like floor frames ) depending on your needs.

4. Once you’re happy with the placement, call a contractor to perform the job, whether it’s for interior or exterior use of objects – they can cement brick into corners and add mounting equipment from outside if necessary!

5. Once this is completed, you’ll need to put something in front of it (preferably at least 1-foot thick) and then proceed with the work that will allow you to open/close the safe easily.

6. It’s important that they’re mounted within a small space but still functional; the best practice is to opt for strong locks and bolts rather than flimsy handles.

7. Two or three safety features are highly recommended – window bars, motion detectors, mirror glass that block you see into the safe (mirrors used will require mounting on both sides of your closet to allow for a full-size opening), and constant bright LED lighting to keep the contents visible without being too “nightlight” if that’s an issue.

How to install a safe in a closet?

With that done, we can move forward with installing this nice full-size cabinet into our storage area then moving all of our extra guns up.

Some people are concerned about the safety of their guns. Locking mechanisms typically feature a crossbar that extends through to the rear or outsides so it can be locked while leaving enough room to insert your key in addition to looking for security purposes.

As you can see, you could actually pretty much put this directly ahead of your firing line, and if the safe were positioned correctly with the best locks, it would be impossible for anyone to get in there during normal range activities without a hand drill or anything similar.

So we still have some time until we can get all of these guys hung up. However, you should test the doors and bolts before installation.

In addition, very distinct attention must be paid to the hammers and screws that are going into this project – it is best if they’re guided through metal dowels in order to avoid any damage.

Where to Put Your Gun Safe to Avoid Water/Humidity Damage?

When looking for a safe, you want to avoid putting it in an area where water/moisture is common – whether sitting near the bathroom or any other type of moisture.

The high humidity around your home may not seem harmful when dry, but a 10% increase in moisture level can make it a breeding ground for molds, mildew, and other fungi/microbes.

It’s no surprise you’d experience increased intrusion in areas with higher humidity.

However, you can always do everything possible to ensure your safe stay dry.

Among them-

  • Putting it someplace where there’s no chance of water standing,

  • Covering it with good plastic if needed to stay dry (e.g., special PVC that isn’t typically used in construction),

  • Safe door sealants, including polyurethane caulk.

But note that even with this degree of protection/caulking, the safe is still exposed to airflow – meaning temperature fluctuations could affect it, or if not protected properly, water could even seep into it.

During winter, refrigerated temperature changes could potentially cause your safe to freeze, especially unless you have insulated/frost-proofed walls.

The safest options are mechanical locking mechanisms (like this ) or encapsulating moisture’s possible entryway(s) with caulk.

Closing Thoughts

When you consider the best way to build a portable closet with firearms, then some things deserve your consideration. Again, it is always better to be sure of the outcome if you decide upon one thing over another.

The model of your cabinet shall, however, depend entirely on the type of gun it houses.

Instead, please don’t underestimate the value of having an expert with you when these are made; they can bring their knowledge to ensure that all goes off without a hitch.
