Recent California mold litigation reveals several important trends that property managers and landlords must understand. Courts are increasingly willing to impose substantial financial penalties on property owners who demonstrate patterns of negligence or deliberate concealment.
The evolution from relatively modest settlements to multi-million dollar jury verdicts indicates growing judicial and jury recognition of mold’s serious health impacts.
California mold law sets high standards for property owners and managers. Failing to remediate mold in rental units can result in costly lawsuits, significant health impacts for tenants, and legal consequences for those responsible.
Both tenants and landlords should be aware of their rights and obligations under the California Warranty of Habitability and related statutes.
These cases often result in substantial settlements and highlight the responsibilities of property managers to ensure safe living conditions for tenants.
$48 Million Los Angeles Apartment Complex Settlement
In 2022, tenants in a Los Angeles apartment complex achieved one of the largest mold settlements in California history. The class-action lawsuit alleged that the property management company failed to remediate severe black mold and water damage issues despite numerous tenant complaints.
Residents suffered from severe respiratory illnesses due to prolonged exposure to toxic mold conditions. The $48 million settlement covered medical expenses, rent reimbursement, and property damage claims for affected tenants.
The lawsuit demonstrated the severe consequences when property managers ignore persistent mold problems and fail to take corrective action. The substantial settlement reflects both the number of affected tenants and the severity of health impacts documented in the case.
$42 Million Silicon Valley Workplace Mold Contamination
A 2021 case involving a Silicon Valley office building resulted in a $42 million settlement for employees who developed chronic illnesses, headaches, and neurological issues. The toxic mold contamination was traced to the building’s HVAC system, which had not been properly maintained.
Both the employer and building owner were found liable for failing to maintain safe working conditions.
This case highlights that mold liability extends beyond residential properties to commercial buildings and workplaces. The substantial settlement compensated affected employees for their extensive health problems and medical treatment costs.
$39 Million School District Mold Exposure Case
In 2019, a California school district settled a major mold exposure lawsuit for $39 million after students and teachers developed asthma and chronic sinus infections from black mold growth in classrooms.
The district had ignored multiple warnings from health inspectors and maintenance staff about the deteriorating conditions. The settlement provided funds for medical care, school renovations, and compensation for affected families.
This case underscores institutional liability when organizations fail to heed professional warnings about mold hazards. The school district’s negligence in addressing known problems resulted in widespread health impacts and substantial financial consequences.
Lawsuit: $33 Million Settlement in Oakland – Negligent Landlord Mold Exposure
In 2020, one of the largest mold-related settlements to date involved tenants of a low-income housing complex in Oakland. The lawsuit was brought against the property owner for failing to address persistent water leaks and mold contamination, which caused severe health effects among residents.
The plaintiffs’ counsel argued that the landlord disregarded recommendations to remediate the mold, despite knowing about elevated airborne levels and visible growth within the units.
The law firm representing the tenants was highly specialized in toxic mold litigation and successfully negotiated the multimillion-dollar settlement. This case set a precedent regarding the legal duty of property owners to maintain rental units free from hazardous mold and highlighted the importance of tenant protections under California law.
PAMA Management – Widespread Tenant Exploitation Lawsuit
In June 2025, California Attorney General Rob Bonta filed a major lawsuit against Southern California real estate tycoon Mike Nijjar and his family companies, known as PAMA Management. The suit alleges widespread violations of housing and tenant laws affecting PAMA’s 22,000 rental units, primarily in low-income Southern California neighborhoods.
While broader than just mold issues, the lawsuit includes allegations of subjecting tenants to vermin infestations, overflowing sewage, and slum-like conditions. The Attorney General’s investigation revealed that PAMA exploited vulnerable families by refusing to invest in pest eradication, roof repairs, and functioning plumbing systems while deceiving tenants about their legal rights.
“PAMA and the companies owned by Mike Nijjar and his family are notorious for their rampant, slum-like conditions — some so bad that residents have suffered tragic results,” Bonta said in a statement.
“Our investigation into Nijjar’s properties revealed PAMA exploited vulnerable families, refusing to invest the resources needed to eradicate pest infestations, fix outdated roofs and install functioning plumbing systems, all while deceiving tenants about their rights to sue their landlord and demand repairs.”
This case represents one of the largest residential property management lawsuits in California history, targeting a multi-billion dollar real estate empire.
Lawsuit: Woodland Village San Marcos – $1.2 Million Settlement
A notable San Diego case involved Woodland Village San Marcos, a luxury senior living community. The management allegedly failed to address flooding and water damage from a leak in the unit above, leading to significant mold growth.
The affected tenant, with preexisting COPD, experienced exacerbated symptoms due to mold exposure, requiring frequent hospitalization.
San Diego toxic mold attorney Jeff LaFave and co-counsel represented the plaintiff, arguing that the property manager ignored professional recommendations for remediation.
Evidence included management’s own mold testing results. This case demonstrates the importance of responding promptly and adequately to water damage to prevent mold-related health issues.
Lawsuit: Greenberg Property Management – $500,000 Settlement, La Jolla
Plaintiffs in this case rented a high-value home in La Jolla managed by Greenberg Property Management. The lawsuit alleged improper drainage and leaks caused moisture intrusion and toxic mold growth, making the home uninhabitable and causing the occupants to fall ill.
The property manager was accused of failing to conduct routine and preventative maintenance, which would have addressed the underlying issues.
Attorney Jeff LaFave again led litigation for the plaintiffs, resulting in a settlement of $500,000. The case highlighted the duty of management companies to conduct inspections and address mold risks in a timely manner.
Lawsuit: Anza Management – $6.6 Million Jury Award, Las Palomas Apartments
In a high-profile 2025 case, Newport Beach-based Anza Management faced a $6.6 million judgment following a jury trial in Nevada, specifically involving tenants of the Las Palomas Apartments. Plaintiffs endured toxic mold due to unfixed leaks, resulting in respiratory issues, asthma attacks, and a ceiling collapse.
The jury found the landlord negligently ignored multiple reports of water leaks and mold over several years.
The law firm representing the tenants presented evidence of repeated neglect and prior complaints logged with the property manager. The successful outcome signaled a strong message to property managers about the consequences of ignoring tenants’ health and safety.
Lawsuit: Irvine Company – Newport Bluffs Apartments Mold Claims
The Irvine Company, California’s largest property owner, became the subject of multiple lawsuits alleging it concealed mold issues at its Newport Bluffs apartment complex. Former employees testified that management often performed only cosmetic repairs and withheld information from tenants and inspectors.
The litigation included both personal injury claims for affected renters and whistleblower claims from employees who reported mold and water intrusion issues to municipal authorities.
Attorney Alan Bell, with local co-counsel Benjamin Sampson and Joshua Bordin-Wosk, led the legal action against the Irvine Company. The lawsuits claim that the Irvine Company prioritized profit over its duty to provide safe housing, showing a pattern of neglect and misrepresentation about the presence of mold.
Lawsuit: Carnahan vs. Newport Crest HOA – $857,000 Settlement
In Newport Beach, a resident sued the Newport Crest Homeowners Association and its property management company over chronic water intrusion and subsequent toxic mold growth. Health effects ranged from chronic allergies to skin irritation. The property manager allegedly neglected regular maintenance, leading to unsafe living conditions for the plaintiff.
Again, attorney Jeff LaFave was at the helm, settling the case for $857,000. This case reinforces the responsibility property managers and HOAs have to maintain water-tight homes and condominiums.
