Re: Nominal lumber specifications

[Subject Prev][Subject Next][Thread Prev][Thread Next]
In the early fifties, my Dad added a garage to our house and I remember him grumbling that they had just reduced the lumber sizes. I believe that may be when they went from 1 5/8" x 3 5/8" to 1.5" x3.5" for a 2x4, but as a typical teen-ager I wasn't paying that much attention.

My house was built in California in 1958 using nominal lumber: 1 5/8" thick.  I believe in the '70s, they went to the 1 1/2" nominal thickness x whatever depth dimensions were used.  UBC '67 notes nominal lumber dimensions but I can't find an older code.

Time to place a little bet with an Architect.

Subject: Nominal lumber specifications

Does anyone have any information when the "UBC" or other building codes for California 1st started specifying nominal lumber dimensions? For example 1.5" x 3.5" instead of 2" x 4".



We have a project and the architect is saying that nominal lumber began to be used during the 1970's, but I have seen homes in the 50's and 60's framed with nominal lumber and not "rough" dimensions.

Any information would be greatly appreciated
