Do ceiling joists need to rest on cross beams?

This is fine. It's a wooden open web truss system. The weight is transferred to the column at the one top point. The lower bar and diagonal bracing are to prevent the top bar from sagging over a ...

Is it safe to screw into a single support beam holding up an entire house?

At least in the area where I live, that type of support post is used when a house is modified (wall was removed, to prop up a sagging beam, etc). If the house was designed to have a support post ...

Is it safe to screw into a single support beam holding up an entire house?

Notice the post is not just supporting the beam, it’s holding up ends of the boards that make up the beam! Would strongly recommend consulting an engineer ASAP and having the beam supported correctly. ...

Contact surface between subfloor and joists

Just add (nail, screw, and/or glue) additional framing material to the side face of the joist to provide more bearing area for the subfloor.

How much weight can lagbolts hold, or how can I support this piece of slate on a wall?

Shear strength of the hardware isn't going to be a real concern. A single 1/4" Grade 5 lag bolt, in a configuration like this, will fail at roughly 13,000 lbs. Even 1/8" lag screws (well down into "...

How to support 20 feet of 4 inch pvc drain pipe horizontally along a concrete wall?

Any of the pipe hangers available at your local big-box home improvement store are designed to support a full pipe. They would be just decorations if they didn't... Pick a type that seems simplest to ...

does this look like an up to code support beam?

For an 8.5' span I'd say no. The purpose of the jack studs isn't just to hold up the header - it also helps distribute the load more evenly to the foundation. For that wide of a span the IRC calls ...

How to calculate sizing for treehouse footing?

Hmmm...no digging in the ground and no concrete. Sounds like the four perimeter beams will be your foundation. They’ll need to be treated for ground contact (pressure treated) as you indicate. ...

Can I safely remove stringer in garage?

Unless there is more to this than you've shown, this was added AFTER construction to permit the installation of the squat rack. As such, it's NOT a part of the garage's structure and so removing it ...

Is there any way to stop a low-profile desk from racking back and forth?

The "very minimalist look" is a bit too minimalist for boring old function. You may regret "living with it" when it fails and a hunk of rock lands on your foot (or other body part),...

Choosing the correct LVL beam size

Nope, a 2 ply 1-3/4" x 11-7/8" LVL can't span that long with this much roof on it. With a 19' span (and completely guessing on the roof span and live loading for your area) you're looking at at least ...

Vertical loft supports doing nothing?

Your picture suggests that they are different truss types. The fact that one doesn't have the vertical member in the middle doesn't mean that it isn't needed. I could design a roof without any bracing ...
