Property inspection checklist
If you're planning to buy property, you should first do a detailed onsite inspection. By checking out conditions (indoors and outdoors) before you buy the property, you can prevent surprises later.
For more detailed information, please read Contaminated Property Considerations: Focus on Real Estate Transactions.
Home owners and small businesses
Be sure to check both indoors and outdoors.
Do you detect unusual or noxious fumes or odors?
Drinking water quality
- Do you detect unusual taste, color, or odor?
- Has there been any change in the quality of the drinking water?
Surface water quality
- Are there any settling ponds on the property?
- Is there any unnaturally colored surface water present?
(in puddles, ditches, ponds, lake, stream, river, etc.)
- Is there now / was there ever a septic system on the property?
If so, check past history of the property — chemicals may have been dumped into the septic system if certain types of business uses or illegal drug lab activity occurred.
Land (soil) quality
- Lack of vegetation; presence of sick or dead vegetation.
- Presence of oily or stained dirt.
- Indication of current or past storage of fuel, chemicals, hazardous substances.
- Presence of chemical, pesticide, or unknown containers (empty or full).
- Containers or drums with unknown contents.
- Presence of fill consisting of waste materials.
Adjacent properties and surrounding area
- Proximity of property to known or suspected hazardous waste sites or sources.
- Proximity of property to industrial or commercial areas.
- Proximity of property to a major highway or railroad line.
