More than 100 former tenants of the Parkside Collective apartment complex in Aurora, Colorado, have filed a lawsuit against the building’s management and contractors, alleging negligence related to a 2022 explosion that left many homeless. The explosion, which occurred on September 10, 2022, in a fourth-floor utility room, was caused by a broken electrical conduit that led to a dangerous buildup of hydrogen gas. Residents, who had been evacuated due to a fire alarm, were hit by falling debris from the blast.

The lawsuit claims that Holland Residential, the property management company, failed to secure the building after the incident and ignored repeated complaints about electrical problems. Contractors Milender White, Elite Surface Infrastructure, Front Range Electrical Engineering, and Courtesy Electric are also named in the lawsuit for their roles in the improper construction and maintenance that led to the explosion. The case was initially filed on August 30, 2023, in Arapahoe County District Court, with an amended complaint submitted in early September. The complex has since reopened under the name Stella on the Park.
