I'm building a small house with a crawlspace foundation in Northern California. Is it ok to use the brown pressure treated DF rated UC4A for the sill? I believe ok to use if rated above UC1 but want to be sure.

Also, if the end of a sill splits a bit at the bolt, do I need to replace the whole sill? Lots of sill bolts here in CA!

check with your lumber supplier as to if the brown treated wood is rated for your purpose.. as for the split if the part thats split is going to be fastened down i will cut the defect out of the pc of wood and go from there

Would be great if someone knows from here. I will check with building but I'm going to spend alot of time with building so I want to use only when needed. I'm hoping someone knows this from California. Its all that local hardware supplier stocks (big local chain). :biggrin2:

Below is from AWPA site:

"Note that in most cases, wood treated to a higher Use Category may be used for applications in a lower Use Category. For example, sill plates are a UC2 application, but you may use wood treated to UC2 requirements or higher, such as UC3B. "

I'm in NJ. The only brown pt lumber I see is rated for under ground or for weather exposure beams. Non critical fence posts are green pt only, comparing.
There or here, I would think green pt was good for sills. Sills must never be getting wet. Example, I replaced 4' high driveway retaining wall. 6x6 pt, and probably about 40 yrs. Bottom course, always saturated with water, came out looking new. The tops were mostly eaten away by the oxygen using bacteria between the wet-dry cycles.

Thanks for all responses. That's the confusion I have. The brown pressure treated wood is rated for ground and mild water exposure. Hopefully someone that works on framing will see this. I know Contractor Talk has a strict "pro" filter but I'm betting many of my questions will be a bit more specific in knowledge need that DIY as I'm building my own house.....:vs_no_no_no:

Wanted to follow up with findings. I spoke with building and he determined that although not as clear as should be in code, should be fine. That's all I needed. Building a house will school me fast!
