Most people worry about safety when driving, walking busy streets, or spending time in public spaces. But home should never be the place where danger hides. Unfortunately, many California tenants discover that their own living space may expose them to toxic mold they cannot see and did not cause.
When mold begins spreading inside your rental home or building, it can cause significant and sometimes long-lasting health problems. If the exposure occurs because a landlord or property owner failed to maintain safe, habitable conditions, you may have the right to pursue a toxic mold personal injury claim.
The Law Offices of Katherine Cohan, APLC assists tenants throughout California who have suffered illnesses, property loss, or emotional distress due to mold contamination. This guide explains what toxic mold is, how exposure is diagnosed, your legal rights, and how you can hold negligent landlords accountable.
Not all mold is dangerous, but certain species can trigger severe health effects, especially when exposure is prolonged. According to the Centers for Disease Control and Prevention (CDC), the most common indoor molds include:
Mold thrives anywhere moisture is present. It often spreads on and within:
Mold enters homes through open windows, vents, air conditioning systems, and even clothing or pets. Once moisture becomes trapped behind a wall, beneath flooring, or around leaking plumbing, spores begin to grow and spread rapidly.
Mold affects people differently. Some tenants show no symptoms at all, while others develop significant health issues. The CDC lists the following symptoms as common signs of mold exposure:
Large mold infestations are often visible or produce a musty odor, but hidden mold inside walls or ceilings can be just as harmful.
Doctors typically rely on a combination of patient symptoms, medical history, and testing to identify mold-related health problems. Common diagnostic methods include:
Small amounts of suspected allergens are placed on the skin using tiny punctures. If a raised bump appears, it suggests mold sensitivity.
A blood sample measures immunoglobulin E (IgE) antibodies to determine whether the immune system is reacting to mold.
Individuals with weakened immune systems may require blood cultures or imaging to detect systemic fungal infections.
No single test can “prove” toxic mold exposure, which is why medical documentation, a detailed symptom history, and environmental evidence are essential in legal cases.
Yes. California law provides strong protections for tenants who become sick or whose property is damaged due to mold caused by poor maintenance or unsafe living conditions.
You may have a claim against:

Winning a toxic mold case requires showing:
Evidence may include:
The Law Offices of Katherine Cohan, APLC helps tenants gather this evidence, establish a timeline, and build a clear causal link between the landlord’s negligence and your injuries.
Depending on the severity of your case, you may pursue:
Courts may award punitive damages in cases where landlords knowingly ignored mold hazards or repeatedly exposed tenants to dangerous conditions. These damages punish egregious conduct and deter future misconduct.
Yes. Most toxic mold personal injury cases must be filed within two years from the date of injury.
Claims involving government entities have much shorter deadlines, often requiring notice within six months.
Because mold injuries often develop gradually, you should contact an attorney as soon as symptoms appear or mold is discovered. Acting quickly protects your right to file a claim.
According to the CDC, visible or odorous mold already indicates a potential health risk, regardless of the species. While home testing kits exist, they often lack accuracy and may compromise evidence.
Before removing mold, cleaning surfaces, or conducting DIY testing, tenants should seek legal counsel. At The Law Offices of Katherine Cohan, APLC, we help clients document mold conditions properly and avoid losing valuable evidence.
The CDC recommends several steps to reduce mold growth inside homes:
Even with proper precautions, tenants cannot prevent mold caused by structural issues, roof damage, or plumbing failures. These are the landlord’s responsibility under California law.
