California homeowners affected by the Eaton Fire may soon get more help rebuilding. State officials are considering extending permit fee waivers to hundreds of additional homes that suffered smoke and soot damage, even if they were not directly burned.
This expansion recognizes what many homeowners have learned the hard way: wildfire smoke does not stop at property lines. Soot particles can travel miles from the fire's edge, settling on surfaces inside homes and coating HVAC systems with harmful residue. For families in Los Angeles County and surrounding areas, this contamination poses ongoing health and safety concerns.
The Eaton Fire, which burned through Altadena and neighboring communities earlier this year, left a trail of destruction that extends far beyond the visible burn zone. Smoke-damaged homes may look fine from the outside but harbor hidden contamination inside walls, ductwork, and on household surfaces.

Your heating and cooling system acts like the lungs of your home. During a wildfire, even if you keep windows closed, your HVAC system can pull smoke particles inside. These particles settle on ducts, filters, coils, and vents. Every time the system runs, it can recirculate soot throughout your living space.
Soot is not just ash. It contains a mix of chemicals, heavy metals, and fine particles created when homes, vehicles, and vegetation burn. In California, where many structures were built before 1978, burning buildings can release lead from old paint and asbestos from insulation materials. MycoTest's state-by-state environmental hazard map shows elevated risk in California for exactly these reasons.
Signs Your Home May Have Soot Contamination
Not all smoke damage is obvious. Here are warning signs that soot may have infiltrated your home:
- Visible dark residue on walls, ceilings, or around air vents
- A persistent smoky or chemical smell that does not fade with airing out
- Discolored HVAC filters that turn gray or black quickly after replacement
- Staining on light-colored surfaces such as curtains, blinds, or upholstery
- Oily or greasy film on counters, appliances, or glass
If you notice any of these signs, testing the soot residue on surfaces can help you understand what contaminants are present and whether professional remediation is needed.
What the Permit Fee Waiver Extension Means
The original permit fee waivers applied mainly to homes that burned completely. Extending these waivers to smoke-damaged properties acknowledges that cleanup and rebuilding costs add up quickly, even when the structure is still standing.
Homeowners in the affected areas should contact their local building department to check eligibility. Documenting contamination with lab testing can support insurance claims and waiver applications by providing evidence of smoke damage.
Taking Action Now
California homeowners in wildfire-affected areas should not wait to assess their homes. Soot contamination does not improve over time. The longer particles sit on surfaces and inside HVAC systems, the harder they become to remove.
Start by replacing HVAC filters and having ducts professionally inspected. Before hiring a remediation company, consider testing soot samples from surfaces in your home. This gives you baseline data on what contaminants are present, helping you make informed decisions about cleanup.
The MycoTest DIY Soot Test Kit lets you collect surface samples yourself and send them to a certified lab for analysis. Results arrive in days, giving California homeowners the information they need to protect their families and document damage for insurance or permit purposes.
Frequently Asked Questions
How do I know if wildfire smoke damaged my HVAC system?
Check your air filters for unusual discoloration, look for dark residue around vents, and notice if a smoky smell persists when the system runs. Testing soot samples from surfaces near vents can confirm whether harmful particles have settled in your home.
Can I clean soot contamination myself or do I need a professional?
Light surface soot can sometimes be cleaned with proper techniques, but HVAC systems and heavy contamination typically require professional remediation. Testing first helps you understand the severity and type of contaminants present before deciding on cleanup methods.
Will my homeowner's insurance cover smoke damage from a nearby wildfire?
Many policies cover smoke damage even if your home did not burn directly. Document all contamination with photos and lab test results. Having certified test results showing the presence of soot or other contaminants strengthens your claim.
