You're standing in your kitchen with a sledgehammer, looking at the wall between you and the dining room, and somewhere in the back of your mind you're remembering that someone told you you might need "a letter from an engineer." What is that? Do you actually need one? How much does it cost? Where do you even start?
Here's the short version: in almost every Utah jurisdiction, if the wall you want to remove is load-bearing, yes — you need a signed and sealed letter from a licensed structural engineer before the city will permit the work. It's not a hoop the city invented to annoy you. It's the only thing standing between your remodel and a sagging ceiling six months later.
What "load-bearing" actually means
A load-bearing wall is any wall that's holding up something above it — roof framing, a second floor, an attic, or another wall. When you remove it, that load has to go somewhere, and in almost every case the answer is "it has to go through a new beam to new bearing points." The engineer's job is to size the beam, locate the new bearing points, and design the connections.
Walls that are not load-bearing are called partition walls. They're just dividing space. You can take them out without engineering as long as you're not changing anything else.
How can you tell if a wall is load-bearing?
A few starting checks (none of them are guaranteed):
- Look at the floor joists above. If the joists run perpendicular to (across) the wall, the wall is probably bearing. If they run parallel to the wall, it might not be.
- Look at the basement or crawlspace below. Is there a beam or wall directly under the one you want to remove? If yes, the upper wall is probably bearing.
- Look at the wall itself. Bearing walls are usually framed with 2x6 studs or with 2x4 studs at tighter spacing than partition walls. Headers above doors and openings are another tell.
- Look at the original house plans if you have them. Bearing walls are usually marked. Most homeowners don't have the plans.
Important: none of these are definitive. Houses in northern Utah have lateral systems (shear walls) that look like ordinary walls but aren't supposed to be removed even though they're not technically gravity bearing. The only way to be sure is to have an engineer look.
When does Utah require an engineer letter?
Every Davis and Weber county jurisdiction we work in (Syracuse, Layton, Clearfield, Kaysville, Farmington, Ogden, Roy, etc.) requires engineered documentation for the removal of any load-bearing element. The relevant code is the IRC adopted by your city, with Utah amendments. Specifically:
- Removal of any load-bearing wall, post, or beam requires engineered design.
- The design has to include the new beam size, bearing points, and connections.
- The deliverable has to be signed and sealed by a Utah-licensed professional engineer.
Some homeowners try to skip this and "just remove the wall." Don't. If your city catches it (and they often do, because permit-required work without permits is one of the first things that comes up in a future home sale inspection), you'll have to retroactively get the letter, and the engineer will often have to design more conservatively because they can't see what's behind the drywall anymore.
What's actually in an engineer letter?
A typical load-bearing wall removal letter is one or two pages. It includes:
- A description of the existing wall and what it supports
- The design loads used (dead, live, and snow as applicable)
- The required beam size — LVL, glulam, steel, whatever the situation calls for, with the exact dimensions
- The bearing point locations and the post/column requirements to take the new load down to the foundation
- The connection details — how the new beam attaches to existing framing
- Any temporary shoring requirements during construction
- The engineer's signature and PE seal
That's it. It's a focused, specific document. A good letter is not 40 pages of disclaimers — it's the answer your contractor needs to do the work and the answer your building department needs to approve the permit.
How much does it cost?
For a single straightforward wall removal, expect $400-$700 in northern Utah. Prices go up if:
- The wall is on a second floor or has unusual loading
- You're removing multiple walls
- The new beam needs to be very long (very long beams force a switch from LVL to steel, which adds complexity)
- A site visit is needed because the existing framing isn't visible from drawings
We give a fixed fee up front, so you know exactly what you're paying before we start. See our pricing page for the full ranges.
How long does it take?
Most letters are 3-7 business days from the time we have the information we need. If you're under a permit deadline, say so — we can often prioritize.
What we'd ask you to send
To give you a fee and start the work, we need:
- A photo of the wall from inside the room
- A sketch or photo showing the floor plan around the wall (or just measurements)
- Whether there's a basement or crawlspace under it (and a photo if you can)
- The number of stories above the wall
- The address (so we can use the right snow load and code year)
That's enough to get a fixed-fee quote back to you the same business day. From there, the letter is usually in your hands inside a week.
One more thing
If you're not sure whether the wall is even load-bearing, send us photos before you commit to anything. Ten minutes of our time can save you a $600 letter fee — and we'd rather tell you "you don't need us for this one" than charge you for a letter you didn't need. That's not the long-term play we're running.
