Is there somewhere in the residential code book what the minimum requirements for plumb walls are and the minimum requirement for level floors are?

How far out of plumb is everything?

I don’t want to sound smart a$% about this but plumb is plumb and level is level. The minimum requirement is just that, plumb and level. I don’t see how
you can build any other way. The only things I can think of not being plumb is a roof and not level a deck.

The “Standards” used by the NAHB, many warranty companies, etc are in a published book called “Residential Construction Performance Guidelines” or one called “Quality Standards For The Professional Remodeler”.
The have different tolerances for walls, floors, concrete cracks, etc. as to what is considered acceptable and within normal tolerances.
You can get it from the NAHB, ITA or the Construction Bookstore. Cost is about $31.

There are no code requiremens. That is the long and short of it.

R. Michael Gray -
Do you ever use the guidelines like L/240, etc?

Dan … that deflection limit of L/240 is also actually a pretty reasonable limit for sloping floors and slabs as a rough guide. Works out to be a slope of about 1" in 20’, which is a common upper limit for HI’s …
Anything greater than that, and my big kids marble will go flying towards the edge ...

Hi. guys;
Out of plumb and level is mostly thought of ,as a performance specification to control human error that is acceptable. No one is perfect, in Construction, especially when it comes to level and plumb.
The ACI, dictates most times, that a concrete floor when checked with a ten foot straight edge, shall not exceed 1/4" at any point. This would not be true when super-flat floors are specified. Walls constructed of masonry will also state the the plumb will not deviate more that 1/4" out of plumb for every ten feet of wall vertical. I have no specific spec.
number to give you, but just what comes at hand at to moment. I believe that this would fall in to performance standards, then anything else.

All measurements have a degree of accuracy.
We have some mighty fine laser levels at work and the accuracy on many of them is 1/4" @ 100' That is pretty level across a 10' room.
You can take my word for it buildings are not absolutely plumb or level.

Hi. Bob;
You need to up-grade, mine is 1/4" in 500’. ha. ha.

for existing buildings. Be careful applying that to slabs which are sometimes sloped for drainage.
I think the NAHB documents Dan referenced are a good guide. Also check out the Texas Residential Construction Commission "Limited Statutory Warranty and Building and Performance Standards" as another guide.
Just my opinion and 2-nickels ...

Mr Knowsbetter
Did I give you permission to address me by my given name? I don’t remember doing so. In the future if you wish to address me you will please use a more formal method of address or, do not bring me up in your inane posts as I do not tolerate informality from nameless posters who have no business being on the message board.

Hi. Larry;
Know the feeling, but calm down, and enjoy the holiday.
Always nice to communicate on this message board, but not worth getting heart-burn over it.
Talk to you later and take care over this ending weekend.
Marcel
