Castleton Park Apartments Outbreak Overview

The Castleton Park Apartments Legionnaires’ disease investigation involves a residential building in the St. George neighborhood of Staten Island’s North Shore.

Unlike community outbreaks involving rooftop cooling towers, this investigation focuses on Legionella contamination within a residential building’s internal water system.

Legionnaires’ disease is a serious form of pneumonia caused by Legionella bacteria. The bacteria can grow in building plumbing systems and spread when contaminated water droplets are inhaled.

Potential sources of exposure include showers, faucets, and other fixtures that produce water mist.

Common symptoms include:

• Fever and chills
• Coughing
• Shortness of breath
• Headaches and muscle aches
• Chest discomfort
• Nausea or diarrhea

The illness can be especially dangerous for adults aged 50 and older, smokers, and people with weakened immune systems or chronic lung conditions.

Anyone experiencing symptoms should seek medical attention. Learn more about Legionnaires’ disease diagnosis and treatment, including why early medical evaluation is important.

September 2026 Update: Legionella Found in Castleton Park Water System

On September 28, 2026, residents of 185 Saint Marks Place received a notice from NYC Health confirming that Legionella bacteria had been detected in their building’s water system.

The investigation followed two confirmed Legionnaires’ disease diagnoses among residents within the previous year.

According to reporting published October 6, health officials advised residents to reduce exposure to water vapor while the building’s water system was being addressed.

Residents were specifically advised to avoid showers because they generate mist that can be inhaled. Officials indicated that tap water could still be consumed and that the contamination did not pose a risk to the surrounding Staten Island community.

NYC Health also confirmed that remediation was underway and that the agency would continue providing guidance and updates.

The publicly available reports did not establish whether both residents contracted their infections from the building’s water system. Additional testing and investigation may be needed to determine the source of each illness.

Public Health Response to Legionnaires in Staten Island

Following the two resident diagnoses, NYC Health began investigating the building’s water system and working with property management to address the contamination.

The reported response included:

• Investigation: NYC Health evaluated the internal water system at 185 Saint Marks Place following two resident Legionnaires’ disease diagnoses.
• Testing & Identification: Legionella bacteria were confirmed in the building’s water system.
• Resident Notifications: Residents received notice of the positive water test on September 28, 2026.
• Exposure Precautions: Health officials advised residents to limit exposure to water mist, including avoiding showers, particularly for people at higher risk.
• Remediation: NYC Health confirmed on October 6 that remediation was underway.
• Community Safety: Officials stated that the investigation did not indicate a Legionella risk to the surrounding community.

Residents should follow the latest instructions from NYC Health and building management, as water-use recommendations may change based on testing and remediation results.

Concerns About Building Water Safety and Resident Communication

The Castleton Park Apartments investigation has also raised concerns among residents about building water safety and communication.

According to Gothamist, residents said that representatives of building management did not attend an October 1, 2026, community meeting and had not provided additional assistance or safety guidance at that time.

These statements reflect residents’ reported experiences and are not established findings of misconduct or negligence.

Public records identify Castleton Preservation LLC in connection with property ownership, while Stellar Management and CAMBA Housing Ventures have documented roles involving property management, acquisition, development, and resident services.

The precise responsibility of each organization for maintaining and treating the affected water system has not been publicly established.

Determining whether any property owner, management company, or contractor failed to meet an applicable legal obligation would require reviewing maintenance records, water-testing results, contracts, and other relevant evidence.

Legal Considerations for Castleton Park Apartments Residents

If you or a loved one contracted Legionnaires’ disease while living at Castleton Park Apartments, you may have potential legal options depending on the circumstances of the illness.

Residential property owners and operators may have legal responsibilities involving building maintenance and reasonably safe conditions. Whether a particular party failed to meet an applicable duty depends on the facts and governing law.

A Castleton Park Legionnaires’ disease lawyer may investigate:

• Building water-system maintenance and inspection records
• Legionella testing and environmental sampling results
• Hot-water temperature and water-treatment records
• Prior complaints or reports of water-quality concerns
• Communications between building management and residents
• The timing of the resident’s symptoms and diagnosis
• Medical records confirming Legionnaires’ disease
• Other potential sources of Legionella exposure

Although Legionella was confirmed in the building’s water system, a positive environmental test alone does not establish that the building caused either resident’s infection or that a particular organization was negligent.

A legal investigation must consider whether the evidence connects an individual’s illness to a specific exposure and supports a claim against a legally responsible party.

Who May Be Responsible for Legionella Contamination at Castleton Park?

Determining legal responsibility for Legionnaires’ disease at an apartment complex requires examining who owned, operated, maintained, and controlled the relevant water systems.

Publicly documented organizations connected with Castleton Park Apartments include:

• Castleton Preservation LLC: Identified in public housing-finance records in connection with property ownership.
• Stellar Management: Identified as a property management company associated with Castleton Park.
• CAMBA Housing Ventures: Identified as an acquisition and development partner providing on-site social services.

These documented roles do not establish that any organization caused the reported illnesses or violated a legal duty.

Depending on the findings, an investigation may also examine contractors responsible for plumbing, water treatment, testing, or maintenance.

A Staten Island Legionnaires lawyer can review available evidence to determine which parties, if any, may be legally responsible.

Can Castleton Park Residents Seek Compensation?

Residents who contracted Legionnaires’ disease may be able to pursue compensation if the evidence supports a valid legal claim.

Depending on the circumstances and applicable law, recoverable damages may include:

• Medical and hospitalization expenses
• Rehabilitation and ongoing treatment costs
• Lost wages or reduced earning capacity
• Physical pain and suffering
• Other legally recoverable losses related to the illness

Severe Legionnaires’ disease can result in substantial medical treatment and a lengthy recovery period. However, the hospitalization status and long-term medical outcomes of the two Castleton Park residents have not been publicly disclosed.

Compensation is not guaranteed, and the availability of a claim depends on establishing the necessary legal elements.

How Long Do You Have to File a Legionnaires’ Disease Claim in New York?

New York generally provides a three-year statute of limitations for personal-injury claims under CPLR § 214.

However, shorter deadlines or additional notice requirements may apply depending on the parties involved and the nature of the claim. The date the filing period begins may also depend on the specific circumstances.

Residents who believe they developed Legionnaires’ disease because of contaminated building water should consider seeking legal guidance promptly.
