Removing a Load-Bearing Wall: Permits and Engineering

Short answer: removing a load-bearing wall needs a building permit almost everywhere, usually with beam and post details and often an engineer's calculations. Seattle, for example, requires a permit for any work on load-bearing supports, whatever the project size. Non-bearing walls vary by city.

Open-concept kitchens are one of the most requested remodels, and they usually start with the same sentence: "Can we take this wall out?" If the wall carries part of the house above it, the answer is "yes, with a beam, an engineer, and a permit." If it does not, the job is much simpler.

This guide explains how to tell the difference, why removing a load-bearing wall almost always needs a building permit, what the engineering package looks like, and how inspections work. Rules are local, so confirm with your AHJ (authority having jurisdiction). See our disclaimer.

Quick answer

• Load-bearing wall: a building permit is required almost everywhere. Seattle, for example, lists "any work on load-bearing supports" as needing a permit regardless of project size.
• Non-bearing partition: some cities treat it as minor interior work; others still want a permit, especially when wiring, plumbing, or ducts run through the wall.
• Not sure which it is? Treat it as load-bearing until a qualified professional says otherwise.

How to tell if a wall is load-bearing

Only an engineer or experienced contractor can confirm it, but these clues help you ask the right questions:

• Joists or rafters above run perpendicular to the wall and rest on it, or splice over it.
• The wall sits directly above a beam, girder, or wall in the basement or crawl space.
• It is an exterior wall, which nearly always carries load.
• There is a wall directly above it on the next floor, or posts and point loads from above.
• Original plans or permit records show it as bearing. You can often find these through the city's permit history (see how to check permit history).

Walls parallel to joists are often non-bearing, but not always. Trusses, flush beams, and past remodels can change the load path. That is why a site visit matters more than a rule of thumb.

Why a permit is required

Removing a bearing wall changes how the weight of the roof, floors, and occupants travels to the foundation. A new beam must be sized for that load, its ends must bear on posts or columns, and those posts need adequate support all the way down to a footing. If any link is undersized, you can get sagging floors, cracked drywall, sticking doors, or in worst cases a structural failure. The permit and inspections exist to check that load path.

What the permit package usually includes

Some small, simple beams can be sized from code tables without an engineer, but most homeowners and many building departments prefer engineered calculations for any bearing-wall removal. Austin, for example, handles this kind of work through its residential interior remodel permit application.

Trade permits often come along

Walls rarely contain only studs. If electrical circuits, plumbing vents, drain lines, or ductwork run through the wall, moving them usually needs separate electrical, plumbing, or mechanical permits. Vents are the tricky one: relocating a plumbing vent can affect the whole drain system. See our kitchen remodel permit guide for how these trade permits stack up in a typical open-concept project. Our Do I need a permit? checker gives a quick first answer for wall removals and the trade work that comes with them.

Inspections

1. Footing inspection (if new footings are needed), before concrete.
2. Framing inspection: beam, posts, connectors, and fasteners visible before drywall. Have the approved plans and engineer's letter on site.
3. Trade rough-ins for any relocated wiring, plumbing, or ducts.
4. Final inspection after finishes.

Do not close the ceiling before the framing inspection. It is the most common reason for a failed inspection on this type of job. Our inspection prep checklist covers what to have ready.

Inspection checklist for a wall removal

Cities set their own inspection lists; see Seattle SDCI and Portland for when a permit is required.

What happens if you skip it

An unpermitted beam is a red flag in any home inspection. Buyers and lenders may ask for an engineer's evaluation, and cities can require you to open the ceiling for inspection through an after-the-fact permit. Insurance claims involving structural damage can also be complicated by unpermitted structural work. See what happens if you renovate without a permit.

How four cities treat taking out a wall

Here's how four published city lists handle wall removal. The load-bearing answer is the same everywhere. The non-bearing answer isn't.

Seattle's $6,000 limit is based on the fair market value of labor and parts, even if you do the work yourself. Your own time counts. If wiring, a vent, or ductwork runs through a non-bearing wall, trade permits usually come into play anyway.

The hidden scope: ceilings, drywall, and what's inside the wall

Taking out a wall almost always means opening the ceiling to set the beam, then patching walls and ceilings afterward. Some cities set drywall limits on permit-free work, and those limits vary a lot. Chicago allows removing and replacing up to 1,000 square feet of drywall or plaster without a permit, as long as no mechanical, electrical, or plumbing system is altered (Chicago interior finishes). Denver's exemption covers patching or replacing a single sheet no larger than 4 by 8 feet (Denver homeowner permits). On a wall removal, the drywall is usually covered by the structural permit anyway. Just don't assume a separate "drywall only" exemption covers the whole job.

Which permit track a wall removal lands on

A single wall with a beam is often a smaller review than people fear. Seattle's subject-to-field-inspection permit is meant for small projects with simpler plan requirements, and the city lists "remodeling a portion of your house" as a common example. Fees are based on project value (Seattle STFI permits). Denver puts small interior remodels in its "Minor Residential" review group (Denver review times). Phoenix says minor work may get an over-the-counter permit, and larger work is routed for plan review (Phoenix additions and remodels). Whether your project qualifies depends on the beam, the posts, and what's below them, so bring the engineer's letter when you ask.

Questions to ask before the wall comes out

• Who confirmed the wall is or isn't bearing, and is that in writing?
• What size and material is the new beam, and will it sit below the ceiling or flush with it?
• Where do the posts land, and do the footings under them need to be bigger or new?
• How will the floor and roof be shored while the wall is out?
• Which wires, pipes, vents, or ducts are in the wall, and who's pulling those trade permits?
• Whose name goes on the permit, and who will be on site for the framing inspection?

FAQ

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

It depends on the city. Some treat it as minor interior work with no permit; others require a permit for any wall removal. If wires, pipes, or ducts are in the wall, those changes usually need trade permits.

Do I need a structural engineer to remove a load-bearing wall?

Often yes. Many building departments require stamped calculations or an engineer's letter for the new beam and posts, especially for longer spans or when point loads land on existing floors.

Can a homeowner pull the permit?

In many jurisdictions an owner-occupant can pull a building permit for their own home, but trade work may still require licensed contractors. See who pulls the building permit.

Is there a dollar amount under which I don't need a permit?

A few cities have one, but it never covers load-bearing work. Seattle exempts minor repairs and alterations of $6,000 or less in a 6-month period, but still requires a permit for any work on load-bearing supports, whatever the cost (Seattle SDCI).

Do I need a permit to build a new closet wall?

Often not. Portland, for example, exempts building non-structural partitions that don't enclose habitable space, such as a closet (Portland). Adding wiring or outlets to the new wall is a separate electrical question.

Does my own labor count toward Seattle's $6,000 limit?

Yes. Seattle bases the limit on the fair market value of labor and parts, even if you do the work yourself, and the exemption never covers load-bearing supports (Seattle SDCI).

Bottom line

If a wall carries load, removing it is structural work: expect a building permit, a sized beam with supported posts and footings, often an engineer's letter, and a framing inspection before the ceiling is closed. Start with our 10-minute AHJ permit checklist, and ask your building department what they need to see.
