I'm planning on getting a gun safe soon. Was going to put it in a bedroom closet and was kinda concerned about the weight of it. One I was looking at was around 375 lb and another was 500lb.(only getting one) I went in the basement and figured out where the safe would be. After looking at the area I think it will be ok but thought would ask for some other opinions....home was built in the late 60s and has 2x8 joist. It has a wooden beam(triple 2x8) that runs entire length of house. The safe would be sitting on the floor above about a foot in front of that beam. Also previous owner put 2x4s under the beam spaced apart so they could nail paneling to it, So guess you could say it has some support under the beam even though its not framed like you would a wall. Then about 3' from the beam is a wall they actually framed. Safe would be sitting above the furnace. With that in the way I can't reinforce the joist at all, not sure would really need it since the beam is there. Also in the same bedroom, I'm a music fanatic so I have 3 big ikea shelves filled with vinyl records. 2 of them are stacked and are against the wall(same direction as joist run) which is right by the closet where safe would go. Other shelf is when you walk in the room but is also near the closet. Is already a good bit of weight in the room with the 3 record shelves.....attached a photo of the area below where the safe would be. You can see the 2x4s in the back, that is where the triple 2x8 beam is. concrete block wall is just to the right. On the left of photo where the 2x4 is that is white from the light, to the left is where the framed wall is that is about 16' or so long....so far don't see any issues from the record shelves and they been there for several years.....what is everyone's opinion with adding a safe? sorry for the long post!
