Staircase accidents in Boulder commonly involve conditions that become more likely with frequent foot traffic and frequent turnover in residential buildings:
- Apartment building entry steps and shared landings: Worn nosing, uneven tread height, or handrails that aren’t secured after maintenance work.
- Seasonal weather tracking: Mud, moisture, and grit from Boulder’s changing conditions can make stair surfaces dangerously slick—especially near building entrances.
- Tourist and event crowds: Visitors moving through hotels, restaurants, and venues may not notice signage, lighting changes, or obstructed stair access.
- Construction-adjacent hazards: Temporary walkways, partial repairs, or “work in progress” areas can create unfamiliar footing or blocked handrails.
These cases often turn on what was wrong, how long it existed, and whether the responsible party acted reasonably to keep stairs safe for the people who use them.
