Framing - Nails vs. Screws | John Sayers’ Recording Studio Design Forum archive

Folks, I told you all that I would take some time to look into the question of framing non-bearing partitions (in the basement or wherever) with screws instead of nails. There was quite a bit of discussion of the intent of the building codes to apply to bearing walls - but not non-bearing walls. What I did was research the IBC - 2003, BOCA 1999 and The CABO ONE and TWO FAMILY DWELLING CODE (I do not have a copy of the IBC residential code - but have no reason to believe that it is any different than anything else i see) and I find the following: In all cases within the various codes - there is no allowance for the construction of studs to plates - or of the various elements (i.e.: header construction - double stud assemblies, corner studs - Jack to stud assemblies, etc.) using anything other than nails or staples. There is no allowance for the use of screws - and this includes sheathing for floors / walls / roofs. The first refrence to screws and screw spacing comes with gypsum wallboards and laths for plaster. Although I am aware that some local building officials have the authority to modify the codes in their jurisdictions (although none are allowed in the entire state of CT) they generally won't do that when dealing with structural issue and no engineering back-up. So if you framed that way - and got away with it - you most probably did just exactly that - got away with it as opposed to being code compliant. Understand one thing - if the building official makes a mistake - and approves something that is not code compliant - that is not the same as getting a modification from the requirements of the building code, you are still responsible under the codes for complying even if the BO approves something that is not compliant The pertinent code references for the various codes are as follows: IBC Section 2304.9 fastening schedule 2304.9.1 BOCA Section 23205.2 Table 2305.2 CABO Section R-402.3 - fastening schedule R-402.3.2 Note: If there is a modification to the published Code Standards allowing this to take place - then it has to be in writing, so if your local official says it's OK - just ask for a copy of the local regulations stating that it is acceptable - otherwise it is not. I would hate to see anything happen - and then have your home owner's insurance refuse to pay because your work was not code compliant - that could get costly real fast. Remember that a mistake on the part of the building official does not constitute a granted modification to the code equiremtns - Mistakes are also addressed within the codes- and it is clear that a mistake on the part of a building official does NOT constitute acceptance of a condition that is not correct - it just places the responsibility with you - the permiy holder. I hope this helped you to understand. Sincerely, Rod
