Open floor plans remain one of the most requested remodels, and that usually means taking out a wall between a kitchen and living room or between two small bedrooms. The first question is always the same: is it a load bearing wall? Some walls simply divide space. Others carry the weight of floors, ceilings and roofs above them down to the foundation, and removing one without a properly designed replacement can lead to sagging, cracking and, in the worst cases, structural failure. This guide explains the clues that suggest a wall is structural, what to look for in the attic and basement, why removal requires an engineer, a permit and temporary shoring, how loads are carried down to footings, what costs are typically involved and how to spot a wall that was removed improperly before you buy a home.

What Is a Load Bearing Wall?

A load bearing wall is a wall that supports weight from above and transfers it down through the structure to the foundation. That weight includes the dead load of the building itself, such as joists, subfloor, drywall, roofing and framing, and live loads such as people, furniture and, on the Front Range, heavy snow on the roof.

A non-load-bearing wall, often called a partition wall, carries only its own weight. It can usually be removed with ordinary demolition care, although it may still contain wiring, plumbing or ductwork that needs to be rerouted.

The distinction is not always obvious from inside a finished room. Two walls that look identical can perform completely different jobs, and some walls carry point loads from a single post or beam end above rather than a continuous line of joists. That is why visual clues are a starting point, not a final answer.

How to Tell If a Wall Is Load Bearing

Several patterns suggest a wall may be structural. None of them is definitive alone, but several together raise the likelihood.

Exterior Walls

Nearly all exterior walls in conventional wood-framed homes are load bearing. They support roof rafters or trusses and floor framing along the perimeter. Openings in exterior walls for new windows or doors need properly sized headers.

Walls Perpendicular to Floor or Ceiling Joists

When joists above a wall run across it at right angles, the wall may be supporting those joists at mid-span. Walls running parallel to joists are less likely to be bearing, although a parallel wall can still carry a point load or sit under a doubled joist that supports something above.

Center Walls

Many homes have a central bearing wall or beam line running roughly down the middle of the house, parallel to the ridge. Joists from each side often lap or butt over this wall. In ranch homes common across Aurora, Lakewood and Littleton, the hallway walls frequently form part of this central bearing line.

Walls Stacked Above Each Other

A wall that sits directly above another wall on the floor below, or directly over a beam in the basement, is a strong candidate. Builders stack bearing walls to carry loads straight down.

Walls Over Beams or Girders

If a basement or crawlspace has a steel or wood beam with posts, the wall directly above that beam line is often carrying load to it. In homes on a pier and beam foundation, the beam lines below help show where interior bearing walls sit above.

Thicker or Doubled Framing

Doubled top plates, large headers over doorways and posts built into a wall can hint at structural duty, though many partition walls also have doubled plates by convention.

Attic and Basement Clues

The best evidence usually comes from looking above and below the wall rather than at the wall itself.

In the Attic

• Trusses or rafters. Engineered roof trusses are typically designed to span from exterior wall to exterior wall, so interior walls below them are often non-bearing for roof loads. Older stick-framed roofs with rafters and ceiling joists often rely on interior walls for support, and you may see struts or braces bearing on a wall’s top plate.
• Ceiling joist laps. Joists that overlap or butt-joint directly over a wall usually mean that wall supports them.
• Strongbacks, posts or purlin braces landing on top of a wall suggest it carries roof load.

The ASHI Standard of Practice notes that inspectors are not required to traverse attic load-bearing components concealed by insulation, which is a reminder that deep insulation can hide the very framing you need to see. Walk only on framing members and use caution.

In the Basement or Crawlspace

• Beams or girders running directly below the wall
• Posts or columns aligned beneath the wall
• Blocking or a doubled joist under the wall line
• Joists lapping over a beam directly below the wall

Original blueprints, if available, also help, though field changes during construction were common. Truss manufacturer drawings sometimes show which interior walls, if any, were intended as bearing points.

Special Cases That Complicate the Answer

Some home types make the bearing question harder than the simple rules suggest.

Two-Story Homes

On the main floor of a two-story house, an interior wall may carry the second floor’s joists, the walls above them and, through those walls, part of the roof. A wall that seems minor on the first floor can be supporting a surprising amount of weight. Removing it often calls for a larger beam than a single-story situation and careful attention to posts and footings.

Split-Level and Bi-Level Homes

Split-level and bi-level designs, common in Front Range neighborhoods built in the 1960s and 1970s, have staggered floor levels. Short walls between levels and walls beside stairs often carry floor framing from one level and sometimes support the edge of another. These walls deserve a closer look than their size suggests.

Truss Roofs With Interior Bearing

Although most trusses span wall to wall, some designs, such as girder trusses or long-span layouts, rely on an interior wall or post. Truss drawings or a truss manufacturer’s review can clarify this, and altering any truss should be done only with engineering approval.

Previously Altered Homes

Earlier remodels may have shifted loads onto walls that were not originally bearing, or added point loads from a beam end hidden inside a wall. That history is often invisible until drywall comes off, which is why a small exploratory opening before planning is common.

Why Removing a Load Bearing Wall Requires an Engineer

Removing a bearing wall is not just taking something out. The load it carried has to go somewhere, which means designing a replacement path: a beam above or flush with the ceiling, posts at each end of that beam, and adequate support below those posts all the way down to the foundation.

A licensed structural engineer typically:

• Confirms whether the wall is bearing and what it supports
• Calculates loads, including snow loads, which vary by elevation and jurisdiction across Colorado
• Specifies beam size and material, such as dimensional lumber, laminated veneer lumber, glulam or steel
• Specifies post sizes and connections at each beam end
• Evaluates whether existing footings can carry new concentrated loads or whether new footings are needed
• Produces stamped drawings for the permit application

Engineering fees for a single wall evaluation and beam design are often a modest share of the project cost compared with the risk of getting it wrong. Our guide to when to call a structural engineer explains how engineers differ from home inspectors and what an evaluation typically includes.

Beam Options: Dropped vs Flush

A dropped beam hangs below the ceiling line and is usually simpler and less expensive to install. A flush beam is set into the ceiling plane so the ceiling looks continuous, which usually means cutting joists and hanging them from the beam with metal hangers. Flush beams are more invasive and may require deeper or stronger members.

Posts and Load Path to Footings

Each end of a new beam concentrates load at a single point. That point load must travel through a post, through any floor framing below, often with solid blocking, and onto a footing that can carry it. In a basement, that may mean a new pad footing poured under a new post. Skipping this step is one of the most common errors in amateur wall removals, and it can show up years later as a sagging floor or a cracked slab around a post.

Permits, Temporary Shoring and Safety

Most Front Range jurisdictions, including Denver, Jefferson County, Arapahoe County and Colorado Springs, generally require a building permit for structural alterations such as removing a bearing wall. Permit review and inspections confirm that the engineer’s design was followed. Unpermitted structural work can also complicate insurance claims and resale.

Before the wall comes out, contractors install temporary shoring, often called temporary walls, on one or both sides to carry the load while the old studs are removed and the new beam and posts go in. Shoring needs to bear on a solid surface and be braced so it cannot shift.

Demolition carries its own hazards. OSHA notes that demolition can involve unknown factors, including approved or unapproved modifications that altered the original design and materials hidden in structural members, and lists an engineering survey by a competent person, covering the structure’s condition and the possibility of unplanned collapse, as part of proper planning before demolition. For homeowners, the practical takeaway is that the person removing the wall should understand what is above it before cutting.

Hazardous Materials in Older Walls

Walls in older homes can contain materials that need care. The EPA notes that remodeling can disturb building materials and suggests having a home inspected by an accredited asbestos professional before a remodel if materials may contain asbestos. Joint compound, textured ceilings and some plasters from older eras are examples. The EPA also requires contractors paid to disturb painted surfaces in pre-1978 homes to be lead-safe certified under its Renovation, Repair and Painting rule.

Signs a Wall Was Removed Improperly

Buyers often encounter homes where a previous owner opened up the floor plan. Most of these remodels are fine, but some were done without engineering or permits. Warning signs include:

• Sagging ceilings or a visible dip along the line where a wall used to be
• Cracks in drywall or plaster, especially diagonal cracks at door corners or long cracks running along the old wall line. Our guide to ceiling cracks explains which patterns suggest structural movement versus normal shrinkage.
• Doors upstairs that stick or swing on their own after a remodel below
• Bouncy or sloping floors on the level above the opening
• Undersized beams, such as a single board where a built-up or engineered beam would be expected
• Beams ending on nothing, with no visible post or a post that does not continue to the foundation
• Patched flooring in a strip where the wall used to sit, combined with ceiling sag above
• New cracks in the basement slab or foundation under posts. Our foundation cracks guide covers which cracks deserve a closer look.

Cosmetic patching is common after these remodels. Repeated cracking along the same lines after repainting is a clue that movement is ongoing. Our drywall repair guide explains why fixing cracks without addressing the cause rarely lasts.

Ask sellers for permits and engineering letters for any opened walls. Many building departments allow permit history lookups by address, which can show whether structural work was approved.

What a Home Inspection Covers

The ASHI Standard of Practice requires inspectors to inspect structural components, including the foundation and framing, and to describe the floor, wall, ceiling and roof structure. It also states that the inspector is not required to provide engineering or architectural services or analysis, or to offer an opinion about the adequacy of structural systems and components.

In practice, an inspector can flag sagging, cracking, missing posts and suspicious beam installations, then recommend evaluation by a structural engineer. Our guide to structural home inspections explains when an engineer’s assessment adds value, and the home inspector hiring guide covers how to choose an inspector who documents structure thoroughly. More framing and foundation topics are collected in the structure and exterior hub.

What Removing a Load Bearing Wall Costs

Costs vary widely with wall length, beam type, whether the beam is dropped or flush, how many utilities run through the wall and how much finish work follows. As a rough 2026 framing:

• Structural engineer evaluation and beam design is often several hundred to a couple of thousand dollars.
• Permits vary by jurisdiction and project valuation.
• Removal with a dropped beam in a simple single-story situation may land in the low-to-mid thousands to around ten thousand dollars or more.
• Flush beams, steel beams, long spans, new footings or second-story loads can push costs well into five figures.
• Rerouting plumbing, ductwork or electrical and patching floors, ceilings and walls add to the total.

Wall removal is often bundled into larger projects. Our guides to kitchen remodel cost and bathroom remodel cost show how structural work fits into overall remodel budgets. These ranges are general estimates, not quotes.

Before You Take Out a Wall

1. Look for the clues above: joist direction, attic framing, basement beams and stacked walls.
2. Open a small inspection hole in the drywall if needed to see what is inside.
3. Hire a structural engineer to confirm and design any replacement.
4. Pull the required permit and schedule inspections.
5. Test or assess older materials for asbestos and lead before demolition.
6. Use a contractor experienced with structural alterations and temporary shoring.
7. Keep stamped drawings, permit records and photos for future buyers.
