More than three years ago, 100 units at a housing building were shut down after Legionnaires’ Disease in the water sickened more than a dozen and killed one person. The water system still hasn’t been replaced and the building sits empty. The seniors who were displaced from their homes want answers. The building’s owner has made several attempts to secure the money needed to replace the water system — “and they have just met road block after road block after road block.” (Source)

A nonprofit that owns the affordable housing building that relocated 90 low-income seniors in 2021 after a Legionnaires’ disease outbreak killed one resident and sickened another 14, says it won’t reopen because the city of Portland and the state haven’t offered them adequate money to do so.

Thirty-two former residents of a North Portland building, who sued their nonprofit housing provider over a Legionnaires’ disease outbreak, reached settlement agreements with the landlords. The senior residents sued the nonprofit owner and manager of the Rosemont Court in February of 2023, alleging the nonprofits hadn’t adequately protected residents during a Legionnaires’ outbreak in 2021. This outbreak left one resident dead and more than a dozen others sick. Former residents who were sickened with Legionnaires’ have not settled and are likely to move to trial. The defendants agreed to settle, and each of the 32 plaintiffs received $8,000. (Source)

Thirty low-income seniors were displaced from the North Portland apartment buildings after a 2021 outbreak of Legionnaires’ disease sickened 14 tenants and killed one. The residents are now suing the building manager and owner, alleging the companies failed to keep them safe from the waterborne bacteria. Most of the plaintiffs who lived at Rosemont Court are asking a Multnomah County circuit judge to award them no more than $10,000 each in damages from the nonprofit Northwest Housing Alternatives and the firm Income Property Management. (One of the plaintiffs, who contracted Legionnaires’, is asking for $750,000.) (Source)

Washington County public health officials say they have not yet pinpointed the source of a recent Legionnaires' disease outbreak in Beaverton, but they have found the legionella bacteria that causes pneumonia in an apartment complex hot tub. "Regular maintenance of hot tubs is important to prevent legionella and other infection-causing bacteria from growing, said Washington County health officer Dr. Christina Baumann. This includes making sure filters are changed, tubs are cleaned frequently and that there is an appropriate chlorine concentration and pH level in the tub." (Source)

In January 2021, Rosemont Court, an affordable housing complex for seniors in North Portland, saw its first residents fall sick with Legionnaires’ Disease, an illness spread by bacteria in tiny water droplets. The county confirmed six cases and suspected four others based on symptoms. By June, another three seniors had gotten sick.


Legionnaires’ disease continues to make headlines today. In 2021, an outbreak of Legionnaires’ disease sickened at least 13 residents of Rosemont Court, a Portland affordable housing project for seniors. This outbreak resulted in one death.
