Who is liable for a stairway injury on someone else’s property?

On Behalf of | Jun 4, 2026 | Premises Liability |

A serious fall on a staircase can leave a person in pain and uncertainty. Questions about responsibility often follow, especially when unsafe stairs at a business or public space contribute to the accident.

If you suffered harm after falling on unsafe stairs on a property owned by another party, knowing who may be liable can help you determine if you have a potential right to recover damages.

Several parties can share responsibility for the accident

Responsibility often depends on who controls the stairway. In most cases, the key issue is who owned or repaired the unsafe condition. Courts generally look at who knew about the danger and failed to address it. Identifying that party can be the first step in determining liability, as several entities may bear responsibility, such as:

  • Property owner: Owners often have a duty to keep stairways reasonably safe for lawful visitors. This can include fixing damaged handrails or poor lighting.
  • Property management company: A management company that oversees repairs could face liability if they ignore complaints. They could also be responsible if they fail to inspect common areas.
  • Commercial tenant: A business leasing the property may be liable for the stairs under its control, depending on the lease and the space’s daily use.
  • Maintenance contractor: A repair company could share fault if careless work leaves a stairway unsafe. They could also be liable if they fail to correct a known hazard.
  • Construction company or manufacturer: Poor design or a defective stair part can also contribute to a fall.

These details matter because stairway cases typically depend on multiple factors. Unsafe stairs can involve many hazards, including uneven steps or slick surfaces. When these dangerous conditions contribute to a fall, determining who is responsible becomes an important part of pursuing compensation.

Courts may also examine the actions of everyone involved in the accident when assigning fault.
In Arizona, the pure comparative negligence rule means an injured person is not automatically barred from recovery if they share some fault. Instead, a court can reduce damages based on that person’s share of responsibility.

Protecting your interests after a serious fall

A stairway injury may affect more than your physical health. Medical care and missed work can create financial strain during your recovery. These challenges can be especially frustrating when the injury resulted from a dangerous condition on someone else’s property.

As you assess your right to compensation, it helps to understand that premises liability cases often involve property control, maintenance duties and notice of dangerous conditions. Since more than one party can share fault, responsibility can be difficult to identify. Legal guidance can help you determine the responsible parties and clarify which facts may matter.
