We're planning to remove a wall between our kitchen and living room to open things up, but I'm worried about whether we need to install a beam or if the existing structure can handle it. How do I know if it's load-bearing before we tear into it?
Load-bearing walls need a structural beam when removed, but non-load-bearing ones don't, so the first step is figuring out which you've got - look for walls that run perpendicular to floor joists, sit above other walls on lower levels, or have a beam or posts directly beneath them, since those are usually load-bearing. You can also check your home's original blueprints if you have them, but honestly the safest move is getting a structural engineer or experienced contractor out to assess it before you make any plans, because removing a load-bearing wall without proper support can cause serious sagging or cracking in your floors and upper levels. Even if it's not load-bearing, you might need permits depending on where you live, so check your local building codes first.
The wall in question almost certainly needs a structural engineer to sign off before you touch it, and that's not optional - it's a code thing. I learned this the hard way when my wife and I wanted to open up our kitchen a few years back; we thought we'd save money by skipping the assessment, but our contractor basically laughed us out of the room and said the permit wouldn't go through without an engineer's stamp. They'll look at things like what's directly above the wall, how the floor joists run, whether there are bearing points underneath, and what kind of load is being carried - and yeah, most walls running perpendicular to those joists and supporting anything above (another floor, roof framing) are load-bearing and will need a beam. The actual beam itself can be steel, LVL, or engineered wood depending on the span and load, but you won't know what you need until someone qualified looks at your specific house.
You'll definitely need a structural engineer's assessment - that's non-negotiable and required by code. One thing people skip: before calling anyone, check your home's original blueprints from the city building department (usually free or cheap to request) to see if that wall's marked as load-bearing. Saves you from paying the engineer if it turns out the wall was never structural in the first place. If the blueprints show it is load-bearing or you can't find them, then yeah, you're looking at a beam installation, but the engineer will tell you exactly what size and how to support it during the work.
