Have to use 3" square washers here in CA. Some of the washers due to bolt placement are preventing rim joist from sitting on sill flush. Is it ok to notch the rim joist where needed so rim joist sits flush on sill?

I'm confused.
Reread your question.
I'd be cutting the washers before I'd be notching the rim joist.

These washers are mandatory here in CA and are 3" by 3" so cutting may be an issue as it would reduce footprint on sill.

I clarified part of original post, :biggrin2:. The rim joist will be cut when I add vents but want to be sure ok to notch maybe 1/4"x3" at most at bottom where meets sill at each washer. Rim Joist is 11 7/8" wide.

Good question for the building inspector on how to proceed.

Rim joist is 11 7/8" wide? You mean it's a 12x12 sitting on the sill plate? Or a 2x12, narrow face sitting on the sill plate, with the cheek (11 7/8") vertical?

It's a good question for the building inspector but only when needed. Hopefully someone will be able to advise here. I'm building this house solo....so inspector and I will have plenty of time. I'd like to reserve my 1000 questions for bigger things that are sure to come up.

Hopefully I can get the help needed here on the DIY forum's other than Ask inspector. Not being specific or hostile to response above...just hoping so as I will have many more questions in all areas.

Any CA framers here?

The I joist are 11 7/8" so lvl rim matches height.

That's what I thought you meant.
Huh. You have earthquake mandated building codes in CA I think.
So some of the washer are sited to where a flush fit of the rim joist to the sill plate is compromised.
Can you look at another, nearby, build site to see what they've done?
Since you're using LVL that's an expensive notch if the building inspector tags it.
Seems like if the notch were cleanly done the Inspector wouldn't have any beef. After all the notch would capture the 3x3 and the vertical loading would lock everything in place. Maybe, maybe. Then again it might get failed cause of the potential for side slippage at the wood-washer-wood sandwich. Tough call. I'd say get an engineer to pass/fail it.

It's fine to cut little out and it's ok to cut 1/16 or so over the thickness of the washer. Don't go wild with the saw, just enough to make room. I'd think about it a little and see where the joists and beams may sit. Joists would be ok to cut, but I'm not sure about cutting anything from a beam, esp if the washers change the area of the bearing surface. If you are not sure, I'd consider recessing all washers. When you mark the bolt holes, set the saw depth and ride the blade over the area.

Thanks for responses! I found a bit of info regarding notches and holes from a mfg site. Your correct thought....expensive mistake if not a go! I've been a building office alot lately and I want to find answers if I can through research and resources when possible

"Rim is not a structural member in the traditional sense, as it is generally not required to span a distance while supporting vertical load. The purpose of rim in conventional construction is to provide lateral stability and transfer vertical loads through the structure. For this general usage, sporadic holes and/or flange notches are not critical. "

I'm going to notch a bit since small area, i'll be clean with cuts so not standing out. Not allowed to recess washers here either....welcome to CA

if this is similar to what you are discribing it is typical, but i could not tell you if its allowed in your municipality.

Mingledtrash - yes, exactly! I figured it had to be somewhere as those washers are huge! Thanks for posting

Once I had to repair a house roof here in Fla where the upper sill plate (propably there's a seperate term for it) was attaching the roof to the block wall. House was mid 50s rancher. Ticky-tacky box with low slope roof. My house😯.
In the 10' section we removed _every_ hex nut (on "J" bolts in the poured concrete) was loose.😨
