Wood deck design 97 UBC
(OP)
Is there a requirement for structural members exposed to weather (deck joists, girders and posts) to be pressure treated or naturally resistant to decay? Project is in
Lake Tahoe area.

I had a project, in the State of Washington, where the contractor did not follow the drawings (which called for P.T. wood)and installed non pressure treated beams under an outdoor deck. When the building inspector noted the variance the owner got around the issue by saying that he would coat the structure with some Snake-oil and deal with the potential reduced life of the structure.
That's my Two-Bits worth.

Does that section relate to wood within 18" of the ground surface?
I have done many exposed lumber structures, especially heavy timber structures. The have never been pressure-treated or naturally decay-resistant timbers. However, for 2 x lumber, I think you definitely have a point.
I have been involved hith a custom home building company that designs/builds post and beam frame type homes. They used decay-resistant wood, which makes sense because you don't want an expensive home that needs constant painting or staining.

We recently did a custom home where a portion of the roof trusses are exposed and painted (that does make me nervous).
