OK. thanks. Maybe I will call my architect who designed the house, just to be sure. Or maybe it'll be easier to get my son to move into the basement thanks again!

Ummm.. no they are not, Commercial floors don't even meet that standard.

Residential floors are 40psf live (anything you put on the floor), and 15-20 dead (weight of the floor itself). Though in most cases a newer home with exceed that standard, depending on the type of joists that are used.

That said, you should be fine, but like others said, need to keep it off carpet, using 3/4" plywood will spread the load over the carpet.

Oh I design buildings for a living, so I have a pretty good idea what I am talking about.

Interesting. I was told that by the builder that built my house. Just goes to show you I guess. Now I'm wondering about my 2500+ tank on the main floor of my house. Good thing I have it on an outside wail where the joists sit on the sill plate.
