Removing a load-bearing wall in a Chicago home is structural work, not demolition. A licensed structural engineer confirms what the wall carries and designs the beam and posts that replace it, and the City of Chicago generally requires a plan-based permit with drawings by an Illinois-licensed architect or structural engineer. In a condo, the association has a say as well.
This guide covers the signs, the work, what the City requires as of 2026, the limits in condos and high-rises, and how it fits into a larger project of interior remodeling in Chicago. If you are still deciding whether an open plan suits your home, start with our guides to open concept kitchen remodeling in Chicago homes and open concept living rooms.
How to Tell If a Wall Is Load-Bearing
A load-bearing wall carries weight from above (floor joists, another wall or the roof) and passes it down toward the foundation. There are clues you can see from the basement and the floors above, but none of them is proof.
Signs worth noting:
- It runs perpendicular to the joists. A wall at right angles to the joists above it is more likely to be carrying them. A wall running parallel to them is more often a partition.
- The joists end on it. If ceiling joists stop at the wall rather than running past it, the wall is very likely supporting them.
- Something solid sits directly beneath it. In the basement, look for a main beam, a steel girder or a foundation wall under the wall’s line.
- Another wall sits directly above it. Load travels floor by floor, so bearing walls tend to stack.
- It is an exterior wall, or a central wall in an older home with a simple roof. Both are common places for bearing walls.
Older homes are less predictable, and a wall that looks like a simple partition may be carrying more than it appears.
A structural engineer should confirm the answer, sometimes by opening a small section of ceiling or plaster to see the framing. Until you have that answer in writing, treat the wall as load-bearing.
What Removing a Load-Bearing Wall Involves
Taking out a bearing wall is really a replacement. The wall’s job moves to a beam, the beam’s ends rest on posts, and the posts carry the load down to something solid.
Temporary Shoring
Before the wall comes out, the crew builds temporary support walls, typically on both sides of it, to hold up the floor or roof above. If another bearing wall or a posted ridge sits above, a second set of shoring may be needed on the floor above. In one project documented by the Journal of Light Construction, temporary shoring walls went up in the basement, the kitchen, the dining room and the attic to remove one bearing wall.
A Beam Designed by a Licensed Structural Engineer
The engineer works out what the wall carries and specifies the beam that replaces it: the material, the size and how it connects at each end. That can mean engineered lumber, steel or a combination of both. The crew then builds from the engineer’s stamped drawings. Beam sizes never come from a rule of thumb, which is why this guide gives none.
Posts That Carry the Load to the Foundation
A beam gathers the wall’s load and delivers it to its 2 ends. Each end needs solid support, usually a new post, and below each post the load has to keep traveling down, through the floor framing, to the foundation. Sometimes that means new posts in the floors below, or a new support column and concrete footing in the basement. The engineer’s drawings show the whole path.
Flush Beams and Dropped Beams
A dropped beam is installed below the ceiling, so it shows as a band across the room where the wall used to be. A flush beam is recessed into the ceiling, so the ceiling can run across the opening without a break; the joists are cut and fastened to the beam with joist hangers. A deep beam can also be partly recessed, with the rest showing below the ceiling.
Which one is possible depends on the joist direction and depth, what sits above, the beam material and the engineer’s design. In one documented project, an engineered lumber beam deep enough for the span would have hung well below the ceiling, so the team installed a steel beam specified by a structural engineer instead. In the Journal of Light Construction project above, the designer first planned a dropped beam partly hidden in an upper cabinet; the team chose a flush beam to simplify the cabinetry and clear the sightline between kitchen and dining room.
What Lives Inside the Wall
A bearing wall often carries more than load. Wires, pipes and ductwork running through it will most likely need to be rerouted. In Chicago, permitted electrical work needs a licensed electrical contractor, and most plumbing work needs a licensed plumbing contractor, with a narrow exception for owners of a detached single-family home doing it themselves.
Opening the plaster walls of an older home also brings health rules. The EPA’s lead Renovation, Repair and Painting Rule covers homes built before 1978 and requires anyone paid to do work that disturbs painted surfaces to be certified in lead-safe work practices. The City’s permit guide also notes that work must follow the lead-safe and asbestos handling practices required by city, state and federal law.
What the City of Chicago Requires
As of 2026, the City’s rules point one way: removing a load-bearing wall needs a permit, and the permit needs a design professional. Rules change, so confirm your project with the Department of Buildings or your contractor before work begins. Our guide to Chicago remodeling permits walks through each permit path.
It Is Not Permit-Free Work
The City’s list of work that does not need a permit covers a limited range of minor work, including nonstructural repairs. That repair exception does not reach work that removes or cuts a structural beam, column or load-bearing support, or that cuts away part of an interior wall.
It Does Not Qualify for an Express Interior Permit
Chicago’s Express Permit Program offers a fast, web-based permit for nonstructural interior alterations. Its terms for nonstructural interior work define structural work to include altering or replacing the structure of load-bearing walls; altering, adding or replacing columns, beams or joists; and any work that requires shoring. Removing a bearing wall typically involves all 3.
It Goes Through a Plan-Based Permit
For any project that needs a plan-based permit, the City says you must hire an Illinois-licensed architect or engineer to prepare the plans, and for most projects that means an Illinois-licensed architect or structural engineer. The plans go to the City through its Standard Plan Review program or, for eligible projects, its Self-Certified program, where a registered Illinois-licensed architect or structural engineer certifies code compliance.
Plan-based permits come with inspections, in most cases several. You must begin work and request the first inspection within 180 days after paying for the permit or the permit’s issue date, whichever is later. Requesting rough and final inspections is the permit holder’s responsibility.
What Happens Without a Permit
The City says it takes unpermitted work very seriously. When it is found, the City issues a stop work order. Work resumes only after the permit is obtained and a stop work order penalty of $1,000 or more is paid, and in most cases the permit fee is tripled. The owner must correct work that violates the code and may have to remove work that cannot be corrected, at the owner’s expense.
Condos and High-Rises Follow Different Rules
In a condo, the first conversation is with the association, not the engineer. Our guide to remodeling a Chicago high-rise condo covers the building rules that shape the rest of the project.
Under the Illinois Condominium Property Act, everything that is not a unit is a common element, and the board is responsible for the care, upkeep and replacement of the common elements. Your declaration and its recorded plat define where your unit ends and describe the common elements. If a wall, column or slab sits outside that line, changing it is not your decision alone.
The City can ask for the association’s sign-off too. Its zoning plan examination page lists a condominium letter among the documents that may be required, and its simpler Express interior permit requires work on condominium property, including inside an individually owned unit, to include an approval letter signed by an authorized representative of the association, such as the property manager or an officer.
The structure itself also changes the question:
- In a smaller, wood-framed condo building, a bearing wall inside your unit may also carry the floors above it. That is a structural question for the engineer and a common-elements question for the association.
- In a concrete high-rise, the slabs may be post-tensioned, with steel tendons held under tension inside the concrete. A contractor who cuts into such a slab can sever a tendon by accident, so before such a slab is touched, the work should start with an engineer experienced in post-tensioning. A ground-penetrating radar scan can locate the tendons and other elements inside a slab.
- Shared systems can limit a high-rise layout. In one published remodel of a Chicago high-rise condo, gutting the unit exposed shared ventilation, plumbing and wiring stacks. The team could not move any of the utility runs, so it designed around them.

How a Design-Build Team Sequences the Work
With a bearing wall, the order matters as much as any single step. On a design-build project, design and construction are planned together, so the engineer’s findings shape the design before it is finished rather than after.
A typical sequence:
- Design conversation and site visit. What you want the space to do, and what the wall might be hiding.
- Structural evaluation. A licensed structural engineer confirms what the wall carries, with small exploratory openings where needed.
- Drawings. An Illinois-licensed architect or structural engineer prepares the permit drawings: the beam, the posts, the connections and the path to the foundation.
- Association approval, for a condo, before the permit application.
- Permit. The plan-based application goes to the City, and work starts only once the permit is issued.
- Shoring, removal and the new beam, built to the drawings.
- Inspections, rough and final, as the permit requires.
- Finishes. Ceiling, walls and floors are patched and finished to the design.
When the wall stands between a kitchen and a dining room, this work becomes part of kitchen remodeling in Chicago, and the beam and any posts are designed alongside the cabinetry, island and lighting.
At Areté, design and construction have sat under one roof since 2002, with an in-house interior design team. Each project is run by a Project Manager. For the wider picture, see our interior remodeling in Chicago services.
Frequently Asked Questions
How Much Does It Cost to Remove a Load-Bearing Wall in Chicago?
There is no reliable single number. The price depends on the span, what the wall carries, the beam and post design, whether the beam is flush or dropped, what has to be rerouted inside the wall, and how the finishes are restored. A real figure comes after the engineer’s evaluation and a contractor’s review of the drawings.
Can I Remove a Load-Bearing Wall Myself?
Chicago lets an owner act as general contractor on their own primary residence in limited cases: an entirely residential property with no more than 6 units, no building taller than 3 stories, and only 1 property per calendar year. The plans still have to come from an Illinois-licensed architect or structural engineer, permitted electrical work still needs a licensed electrical contractor, and the structural risk does not change.
Do I Need a Permit to Remove a Wall That Is Not Load-Bearing?
In most cases, yes. As of 2026, removing a nonstructural wall (other than a closet wall) inside a single residential unit can use the City’s Express interior permit, but only with drawings by an Illinois-licensed architect or structural engineer.
How Long Does the Permit Take?
The City’s Standard Plan Review page gives no single timeline. For eligible Self-Certified applications, the City’s Self-Certified page says permits are typically issued within 10 business days after zoning approval, if all contractor licenses are valid and the property has no building violations or stop work orders.
Will I Need a Post in the Middle of the Room?
Possibly. A longer opening may call for a deeper beam, a different material or an intermediate post. The engineer weighs those options, and a needed post can sometimes be built into an island or cabinetry so it reads as part of the design.
