RE: Wood Frame Floors - Level requireme

[Subject Prev][Subject Next][Thread Prev][Thread Next]

I went to the Arizona Registrar of Contractors web site 
( and they had 
this requirement:

"Uneveness of floor should not exceed 3/16" in 48".  Floors should be level 
within 1/2" in any 12'."

It is my understanding that the Arizona Registrar of Contractors bases their 
tolerances on HUD's, "Minimum Property Standards."

In the situation that you cite, it would seem that slightly less than 1-1/2" 
would be within tolerance *if* the slope was uniform.  However, with the 
elevation difference of 1-3/4" in 35 feet, it has to be out of tolerance 
somewhere or everywhere.

Hope this helps.

Is there an allowable tolerance?
I have a situation in which the floor is 1-3/4 inches different in
elevation in 35 feet.
