That joist is carrying something, even if it the weight of the material that make up that part of the house. I would say it is more than that since the new 2X with the framing anchor is attached to it, is telling me it is passing the load from the new 2X onto the one you wish to drill. Now onto drilling dimensional lumber. Code only allows you to drill a ...

As J comments, this is not a joist, it is a beam on which the joists are hung. Likely there used to be a load-bearing wall there that a prior owner had removed to enlarge the space. They could have opted to have the beam under the joists, which would have allowed space above it but would have reduced ceiling height. Instead they opted (surely at higher cost) ...

Clues that it is likely load bearing are the sheer size (two side by side planks, you don't do that without a reason) and the fact that it looks like it's supporting the studs. What is the span between walls if you follow its length? I don't think you can safely put a hole in that without reinforcing it, and you'd need an engineer to tell you how much ...

This bracket provides a building code approved solution for holes up to 6" through as many joists as you want - Joist Hole Reinforcer. Full disclosure, this is a product that I sell for the exact application in question. There are other ways to reinforce joists with holes, but I believe this is the only one that is code compliant out of the box. Hope ...

I suppose there must be a way you could splice dimensional lumber and make a longer span, but... why? Have a look at wood I-joists. Boise Cascade (BCI), LP Building Products (SolidStart) and Weyerhaeuser (TJI) are three options widely available in the US. (photo below from lpcorp.com) As a single point of reference, a BCI span table shows spans up to or ...

The person that told you grease will collect there was correct. The other issue is each bend creates flow restrictions reducing the flow from the blower. Everything may work fine with 1 or 2 elbows but 4 is beyond the norm and your hood may not work well plus the built in grease trap. I would try and lower the hood 4” and box that in it may look “different “ ...

You not allowed to make that type off hole there is double LVL beam supporting the second floor exterior wall

Depends what it's venting, which may be just the sink, or may be more than the sink, depending how things are presently arranged. Per ICC, a kitchen sink (alone) is 2 DFUs, so if this is a dry vent serving ONLY the kitchen sink, if could be as small as 1-1/4" (which is suitable for JUST 2 DFUs, no more) or it could be 1-1/2" (suitable for up to 8 ...

Anchor bolts are used to: 1) keep your house from sliding along the concrete foundation, 2) resisting the house from being peeled away from the foundation (like a zipper), or 3) keeping the house tight to the foundation so the house doesn’t float away. Your house has shear walls that need to be fastened to the foundation. I live in a high wind area so our ...

You’re better to go with Option C which you haven’t thought of. Those jack studs will need to be replaced as well. Not sure about the codes where you’re at, but I’m not aware of any region that would allow you to scab on to the top of the jacks to fill in the gap between them and the header. Everywhere I’ve built in my 25+ years in the industry requires a ...

Install a suspended ceiling. attach eye anchors to the masonry and use wires to suport the channel which supports the drywall pack your batts above the channels then attach the rigid foam and the drywall using screws.

structurally it looks ok. (assuming you'rte going to fill that 3/4" gap or put blocking in there) 8'x13'5 was going to take 4 sheets of plywood sheet 8'5x13'5 is still going to take 4 sheets. Either use the off-cuts to fill the ends or join sheets end to end

I’d use trusses made with an open area that you can stand up in, in the middle third of the span. Consult a truss manufacturer or a lumber yard. They can design a void in the middle third so you can use it as a storage room or an extra bedroom.

Assume: The two halves of the door are of equal length and weight. (L and W) Let Theta be the angle between vertical, and the upper portion, measured from the opening. Thus, when the door is closed, theta is 0, and when open all the way (impossible in real life) theta is 90 Constraint: The door will form an isosceles triangle at all times when closing. (two ...

Aside from the electrical concerns, whoever installed your plumbing pipe and cut notches in the bottoms of all the floor joists, SERIOUSLY weakened the floor system. Sure, you can cut all sorts of holes into the web of the joist, but DON'T cut the bottom chord. If those joists were 10" or a foot deep, they probably don't have the strength of a 2x6 now....
