Environmental due diligence may include investigating lead, asbestos, mold, radon, contaminated soil, hazardous materials and nearby environmental conditions.
Potential Property Concerns
Depending on age, location and history, buyers may investigate:
- Lead-based paint
- Asbestos-containing materials
- Mold and moisture
- Radon
- Former fuel tanks
- Contaminated soil
- Methamphetamine contamination
- Nearby industrial uses
- Agricultural chemicals
- Water quality
- Hazardous building materials
Property Age Matters
Older construction may contain materials commonly used at the time. Their presence does not automatically mean immediate danger, but disturbance during renovation can create additional risk.
Nearby Uses Matter
Research current and historic nearby uses when relevant, including:
- Dry cleaners
- Gas stations
- Industrial sites
- Landfills
- Agricultural activity
- Mining
- Commercial storage
- Other potentially contaminating operations

No. Environmental conditions may require specialized testing and records.
Who should evaluate health risks?
Use qualified environmental and healthcare professionals.
Environmental testing should be based on the property's age, history, location, visible conditions and intended renovations.
