Buddy of mine wants to move his used safe to his new apartment.
Safe weighs 750 lbs empty and is 27 inches X 24 inches. Its 6 feet tall buts thats not needed in the sq foot of the base. Landlord wont allow it because he says it exceeds 150lbs per sg foot. 2nd story floors are concrete commercial type apt building. Landlord is demanding 150lbs per sg foot max. That means 27X24 at 150lbs = 675lbs max, and that means its over by 75 pounds. I know.....its only 75 pounds. BUT we have to comply with the landlord otherwise he refuses to allow it to be moved in. Question: If the safe is installed on top of a 1/2 inch plywood square pad 30X26, would that be structurally accurate to distribute the weight and stop the landlords claim that its too heavy. 30X26 at 150lbs per sq foot = 812 lbs max allowed and now the safe is under the max weight. By adding this 1/2 inch plywood pad, would the landlord still have a valid claim that its overweight? Thanks. |

Quoted: Adding a slightly larger base at the bottom will make no difference on a safe that is that light. The landlord ultimately gets to make those decisions, but the safe is nowhere near being too heavy for that floor. Edit to say check the link below posted by mchasal. If you want to enlarge the base to spread the load, you will need more that a single sheet of 1/2" plywood (i.e. dimensional lumber to actually carry the load). |

Here's a link about aquariums, ok, so not a gun safe, but a heavy box, so it's the same thing: http://badmanstropicalfish.com/articles/article28.html
The landlord may be referring to the design load of the building which could be 150 psf. But what that means is that the floor is designed to take 150 pounds over EVERY square foot at once. I assume there's a fair amount of empty floor space in the apartment so having a higher loading at a few points, refrigerator, water heater, gun safe, fat guy, is totally ok. See myth #1 and maybe share it with the landlord. |

Since we're probably dealing with "pseudo-engineering" here, you don't have to actually get the load distributed, you just have to get the landlord to think the load's been distributed. So if the landlord goes for the idea of a larger piece of plywood (though I'd probably say 3/4 just to make it sound good) go ahead and stick that plywood under there and enjoy the safe. |
