A water leak at Minneapolis’ LaSalle Plaza has turned into a costly cleanup effort that continues weeks after the incident. The downtown office tower suffered damage across seven floors, with losses estimated at more than $100,000. Building management says an unauthorized person entered an emergency stairwell and damaged a pipe, prompting an ongoing police investigation. Despite the initial leak being discovered on September 28, repairs were still underway in October. Here’s what we know about the damage, the investigation and why restoring the building is taking so long.
A Damaged Water Pipe Triggered the Cleanup
A damaged pipe turned into a major headache for LaSalle Plaza, a 30-story office tower in downtown Minneapolis. According to building management, an unauthorized person entered an emergency stairwell and damaged a pipe, causing water to leak into the building. The incident was discovered on September 28, 2026, and the resulting damage proved extensive enough to require repairs well beyond the initial discovery. Water can travel through stairwells and other connected building spaces, potentially affecting areas far from the original leak. Although the precise sequence of how the water spread has not been publicly detailed, building management confirmed that the incident caused substantial damage. The ongoing work highlights how a seemingly isolated plumbing problem can become a complicated repair project in a large commercial building.
Flooding Affected Seven Floors of the Building
When water escapes inside a multistory office building, the damage can extend well beyond the location of the original plumbing failure. At LaSalle Plaza, the incident affected seven floors, according to Minneapolis police, making the cleanup considerably more involved than addressing a small leak in one room. Water damage across multiple levels can require inspections, drying, repairs to affected interior spaces and assessments of building materials exposed to moisture. The extent of the work depends on which areas were affected and how much water reached them. While officials have not released a detailed breakdown of the damage on each floor, the confirmed impact across seven levels helps explain why the cleanup has continued for weeks. Building management reported that repairs were still underway more than two weeks after the damaged pipe was discovered.
Property Damage Exceeded $100,000
The financial impact of the LaSalle Plaza incident underscores how costly water damage can become in a large office tower. Minneapolis police reported more than $100,000 in damage across seven floors. That figure reflects the scale of the incident, although officials have not provided a detailed itemized account of the losses or explained exactly how the total was calculated. Repair costs in commercial buildings can involve more than fixing the original pipe. Depending on the damage, crews may need to address affected walls, flooring, ceilings and other interior finishes, while also ensuring that impacted areas are properly dried. The building’s management company has confirmed that repairs remain ongoing. Until the affected spaces have been assessed and restored, the final scope of the work may remain unclear. The reported damage amount illustrates why the incident has required an extended response.
Unauthorized Entry Is Central to the Investigation
The circumstances surrounding the incident have added a criminal investigation to the building’s repair work. Building management said an unauthorized person entered an emergency stairwell at LaSalle Plaza and damaged the pipe responsible for the leak. Minneapolis police subsequently sought help identifying an individual connected to the incident and classified the case as involving burglary and trespassing. Investigators said preliminary information suggested that the incident might have involved urban exploration, an activity in which people enter buildings or other locations to explore spaces that are ordinarily inaccessible. However, that remains a suspected explanation rather than a confirmed motive. Police had not announced any arrests connected to the incident as of the morning of October 14, 2026. The investigation may help clarify what happened, but the available reporting does not establish the identity of the person responsible or explain precisely why the pipe was damaged.
Repairs Are Taking Longer Than Two Weeks
For LaSalle Plaza, discovering the leak was only the beginning of the work. More than two weeks after the damaged pipe was found on September 28, building management confirmed that repairs and cleanup were still underway. The affected area spans seven floors, and the reported damage exceeds $100,000, indicating that the response involves more than repairing a single section of plumbing. Water-damaged commercial spaces may need to be inspected, dried and restored before normal use can resume, depending on the severity of the damage. However, building management has not publicly provided a detailed repair schedule, a confirmed completion date or a floor-by-floor account of the work. It would therefore be premature to attribute the duration to any one repair challenge. What is clear is that the incident has required a sustained cleanup effort while police continue investigating the circumstances behind the damage.
