Staircase and Stairwell Accidents in Illinois: Premises Liability Claims

Mon 23 Feb, 2026 / by / Premises Liability

Last Updated: July 9, 2026

Property owners are liable for staircase and stairwell injuries when stairs are defectively designed, poorly maintained, or lack required safety features like handrails or proper lighting. If you fall on poorly maintained stairs, photograph the hazard and obtain building maintenance records. Expert testimony on stair safety codes helps establish negligence.

Staircase and Stairwell Accidents in Illinois: Premises Liability Claims

Under Illinois premises liability law, property owners are liable for staircase and stairwell falls caused by structural or maintenance defects they were responsible for addressing. Unlike most slip-and-fall cases, staircase accidents often point to long-standing defects the owner had clear responsibility to fix. They are also among the most dangerous premises liability incidents: instead of a slip on a flat surface, a staircase fall involves tumbling across multiple steps, often landing on hard surfaces at the bottom. The injuries are frequently severe, broken hips, spinal fractures, traumatic brain injuries, and in some cases, death.

This article is part of our complete guide to premises liability claims in Illinois.

What Causes Staircase Falls?

In Illinois, most staircase falls trace back to six recurring hazards, several of which are governed by the International Building Code (IBC) standards that Illinois municipalities adopt:

  • Missing or broken handrails. Building codes require handrails on staircases for a reason, under the IBC, stairs wider than 44 inches need them on both sides. A missing, loose, or broken handrail eliminates the primary safety device people rely on to prevent falls.
  • Poor lighting. Inadequate lighting in stairwells prevents people from seeing steps, edges, and hazards. Poor lighting is a recurring issue in parking structures, apartment buildings, and commercial properties.
  • Uneven or damaged steps. Cracked, chipped, or uneven steps create tripping hazards. Steps with inconsistent rise heights (the vertical distance between steps) are particularly dangerous because they disrupt the walker’s rhythm.
  • Wet or slippery surfaces. Water, ice, cleaning solution, or worn-smooth surfaces on stairs dramatically increase fall risk. Outdoor staircases exposed to weather and indoor stairs near building entrances are common problem areas.
  • Missing or worn nosing. Step nosing (the front edge of each step) provides visual contrast and traction. When nosing is worn away or missing, it becomes difficult to judge where one step ends and the next begins.
  • Building code violations. Staircase dimensions, handrail specifications, lighting requirements, and material standards are all governed by building codes. Violations create strong evidence of negligence.

Building Code Standards

Illinois municipalities adopt the International Building Code (IBC) with local amendments. Key staircase requirements include: minimum width of 36 inches for residential and 44 inches for commercial, maximum riser height of 7.75 inches, minimum tread depth of 10 inches, handrails required on both sides for stairs wider than 44 inches, adequate lighting at all landings, and slip-resistant surfaces. Building code violations do not automatically establish liability, but they are powerful evidence that the property owner failed to meet the minimum standard of care.

How Do You Prove the Owner Knew About a Dangerous Staircase?

As with all Illinois premises liability cases, you must show the property owner had actual or constructive notice of the dangerous condition. Staircase defects like broken handrails and uneven steps are often long-standing conditions that the property owner clearly knew about or should have discovered through routine inspection. This makes constructive notice easier to establish than in cases involving temporary hazards like spills.

The broader standard is covered at what you have to prove in a premises case.

When Is a Landlord Responsible for Stairwell Falls?

Landlords bear particular responsibility for common-area stairwells in apartment buildings and multi-unit residences. Stairwells are shared spaces that tenants must use, they cannot simply avoid a dangerous staircase. Illinois courts hold landlords to a higher standard for maintaining the common areas that remain under the landlord’s control, and regular inspection of stairwell conditions is expected. If a landlord failed to inspect or repair a stairwell defect, the Peoria premises liability lawyers at Parker & Parker can help establish that failure as the basis for a claim.

Frequently Asked Questions

Can I sue a landlord if I fall on a broken staircase in my apartment building?

Yes. In Illinois, landlords are responsible for maintaining common-area staircases in a reasonably safe condition. If the staircase had a broken handrail, inadequate lighting, damaged steps, or other hazardous conditions that the landlord knew about or should have discovered through routine inspection, you may have a premises liability claim. Report the hazard to management and document it before it is repaired.

Does a building code violation prove the property owner was negligent?

In Illinois, a building code violation is strong evidence of negligence but does not automatically prove liability. You still need to show the violation caused or contributed to your fall and injuries. Illinois municipalities adopt the International Building Code with local amendments, so the precise standard depends on where you fell. Juries view code violations seriously as evidence that the property owner failed to meet basic safety standards.

What evidence should I collect after a staircase accident?

Photograph the staircase, the specific step where you fell, the condition of handrails, the lighting, and any visible defects. Note whether handrails were present and functional, under the IBC standards Illinois municipalities adopt, risers should not exceed 7.75 inches and treads should be at least 10 inches deep, so step dimensions are worth capturing too. Get contact information from any witnesses. Report the incident to the property owner or manager and request a copy of the incident report. Seek medical attention immediately.
