What Does It Cost to Remove a Load-Bearing Wall in Washington?

Almost every open-concept kitchen and great room in a Puget Sound remodel starts the same way: a wall comes out. Done right, it is a well-understood structural project with predictable costs. Here is what the work involves in the Seattle–Snohomish area and what actually drives the price.

The typical numbers

For a single-story home — or a wall on the top floor — removing a load-bearing wall and installing a properly sized beam typically runs $5,000–$12,000 in this market, including engineering, permit, shoring, the beam, and basic patching. When the wall carries a second floor, spans get long, or the beam needs to tuck flush into the ceiling, $10,000–$20,000 is realistic. Projects where plumbing, ductwork, or a main electrical run live inside the wall — common in kitchens — can reach $25,000–$30,000 once rerouting and finish work are counted.

How the work actually happens

First, a structural engineer confirms what the wall carries and sizes the replacement beam and posts — typically a few hundred to a thousand dollars, and required for the permit everywhere we build. Then the crew builds temporary shoring walls, opens the wall, sets the beam — usually engineered lumber (LVL or glulam), occasionally steel for long spans — and carries the new point loads down through posts to footings that can take them. Finally comes the part photos skip: patching floor, ceiling, and walls so nobody can tell a wall was ever there.

What moves the price

  • What is inside the wall. Empty stud bays are cheap. Drains, supply lines, ducts, and packed electrical are not — this is the single biggest variable.
  • Dropped vs. flush beam. A beam below the ceiling is simpler; recessing it into the floor framing above costs more and looks like it was never there.
  • The load path below. New posts need support all the way to earth — sometimes new footings in the crawl space or basement.
  • The age of the house. Pre-1980s homes can add discoveries: undersized framing, old wiring, or materials that need testing before demolition.

Permits are not optional

Every city in our service area treats structural changes as permitted work with inspections — and an unpermitted beam is exactly the kind of thing that derails a future sale. Our guide to remodel permits covers how the process works and how long it takes.

Usually part of something bigger

Most wall removals happen inside a larger project — a kitchen remodel that opens to the living room, or a whole-home remodel that rethinks the main floor. Pricing the wall together with the room is cheaper than doing them a year apart, since the patching and finish work overlap. See our whole-home remodel cost guide for how the full-floor math works.

Wall removal questions

How much does it cost to remove a load-bearing wall?

In the Seattle–Snohomish market, a single-story removal with engineering, permit, beam, and basic patching typically runs $5,000–$12,000. Walls carrying a second floor, long spans, or flush-recessed beams run $10,000–$20,000, and projects with plumbing or ductwork to reroute can reach $25,000–$30,000.

How do I know if a wall is load-bearing?

Clues include joists running perpendicular to the wall, walls stacked through multiple floors, and walls near the center of the house — but the only reliable answer is a structural assessment. We bring an engineer in as the first step, and their sizing letter is required for the permit anyway.

Do I need a permit to remove a load-bearing wall in Washington?

Yes, in every city across Snohomish and King County. The permit requires engineered beam sizing and includes framing inspections. Skipping it is a false economy: unpermitted structural changes routinely surface during appraisals and sales.

How long does removing a wall take?

Once the permit is in hand, the structural work — shoring, beam installation, and patching — usually takes one to two weeks on site. Rerouting plumbing, ducts, or electrical inside the wall adds time, which is why kitchens are the slowest walls to open.
