That persistent musty smell in your apartment or rental home isn’t just unpleasant—it could be making you sick. If you’re dealing with strange odors that won’t go away despite cleaning, you might be experiencing the effects of mVOCs (microbial Volatile Organic Compounds), and your health could be at risk.
What Are Those Strange Smells Really Telling You?
When you walk into your home and notice a musty, earthy, or “old basement” smell, your nose is detecting something more serious than just staleness. These odors are often mVOCs—chemical compounds released by mold and other microorganisms as they grow and multiply in your living space.
Think of mVOCs as the “breath” of mold colonies. Just as humans exhale carbon dioxide, mold releases these volatile compounds into the air as part of its natural life cycle. The problem is that when you breathe in these compounds day after day, they can cause real health problems.
How mVOCs Can Make You Sick
Many California tenants don’t realize that breathing in mVOCs can lead to both immediate and long-term health issues. These microscopic compounds can cause:
Immediate symptoms:
- Persistent headaches that seem to come and go
- Unexplained fatigue, especially when you’re at home
- Respiratory irritation, including coughing or throat scratching
- Eye irritation and watery eyes
- Difficulty concentrating or “brain fog”
Long-term health concerns:
- Worsening of asthma or development of new respiratory issues
- Chronic sinus problems
- Weakened immune system response
- Potential neurological effects from prolonged exposure
The concerning reality is that you can experience these health effects even when you can’t see visible mold growth. The mVOCs travel through the air, meaning mold hidden behind walls, under flooring, or in HVAC systems can still impact your health.
Identifying Common Musty Odors in Your Home
Learning to identify different types of musty odors can help you communicate more effectively with your landlord about potential problems. Here are the most common descriptions tenants use:
“Wet cardboard” or “damp paper” smell: Often indicates mold growth in areas with previous water damage or ongoing moisture issues.
“Dirty socks” or “locker room” odor: May suggest bacterial growth alongside mold, particularly in areas with poor ventilation.
“Basement-like” or “earthy” smell: Classic indicator of mold growth, especially common in ground-floor units or homes with foundation issues.
“Sweet, fruity, or alcohol-like” odor: Can indicate specific types of mold that produce different mVOCs, often found in areas with sugar-rich materials like certain building materials.
Metallic or chemical-like smells: May indicate more serious mold issues or the presence of other indoor air quality problems.
Your Rights as a California Tenant
California law requires landlords to maintain rental properties in habitable condition, which includes addressing mold and indoor air quality issues. If you’re experiencing musty odors and related health symptoms, you have rights under California’s warranty of habitability.
The California Department of Public Health has issued specific guidance on mold in indoor environments, stating that landlords must address moisture problems that lead to mold growth. According to their official statement, property owners are responsible for:
- Investigating and addressing the source of moisture that allows mold growth
- Properly remediating mold contamination
- Ensuring adequate ventilation to prevent mold recurrence
- Responding promptly to tenant reports of mold or musty odors
Taking Action: What You Should Do Right Now
If you’re experiencing musty odors in your rental property, taking the right steps can protect both your health and your legal rights.
Document everything: Take photos of any visible signs of moisture, water damage, or mold. Write down when you notice odors, where they’re strongest, and any health symptoms you’re experiencing.
Notify your landlord in writing: Send a formal written notice describing the musty odors, their location, and any health symptoms you’re experiencing. Keep copies of all communication.
Request professional inspection: Ask your landlord to hire a qualified professional to assess indoor air quality and identify the source of mVOCs.
Seek medical attention: If you’re experiencing health symptoms, see a healthcare provider and mention your concerns about indoor air quality.
Know your options: If your landlord fails to address the problem promptly, you may have legal remedies available under California tenant protection laws.
When Professional Legal Help Becomes Necessary
Sometimes landlords ignore tenant complaints about musty odors and indoor air quality issues, leaving tenants to suffer the health consequences. If your landlord has failed to respond appropriately to your concerns about mVOCs and musty odors, or if you’ve suffered health problems due to poor indoor air quality in your rental property, you may need experienced legal representation.
Tenant rights cases involving mold and indoor air quality can be complex, requiring knowledge of California housing law, health regulations, and the science behind mVOCs and their health effects. An experienced attorney can help you understand your rights, document your case properly, and pursue appropriate compensation for any health impacts you’ve experienced.
Understanding California’s Official Position on Mold
The California Department of Public Health has published comprehensive guidance on mold in indoor environments, acknowledging the serious health risks associated with mold exposure and the mVOCs they produce. Their official statement emphasizes that:
- Mold growth in indoor environments is a public health concern
- Property owners have a responsibility to address moisture problems that lead to mold
- Health symptoms can occur even when mold isn’t visible
- Proper remediation requires addressing the underlying moisture source, not just cleaning visible mold
You can find the complete California Department of Public Health Statement on Mold by searching for “CDPH mold guidance” on the official California Department of Public Health website at cdph.ca.gov.

Musty odors in your home are more than just an inconvenience—they’re a warning sign that your health may be at risk. mVOCs from mold growth can cause real, measurable health effects, and you have the right to live in a safe, healthy environment.
