Avoid disturbing suspected lead-containing materials and follow professional guidance on sample collection.

According to the Environmental Protection Agency (EPA), hazardous waste is generally classified into four main categories:

1. Characteristic Wastes: These exhibit at least one of four hazardous traits: ignitability (flammable, like gasoline), corrosivity (can rust or decompose materials, like car batteries), reactivity (unstable and can explode, like aerosol cans), or toxicity (harmful when ingested, like lead-based paint).

2. Listed Wastes: These are specific wastes from manufacturing and industrial processes that the EPA has officially designated as hazardous. They include byproducts from processes that use solvents, pesticides, and other chemicals.

3. Universal Wastes: These are commonly generated hazardous items that are subject to streamlined regulations. Examples include batteries, pesticides, mercury-containing equipment (e.g., bulbs), and some lamps.

4. Mixed Wastes: This category includes waste that contains both hazardous and radioactive components, making it subject to regulation by both the EPA and the Nuclear Regulatory Commission.

No, a standard home inspection includes the basics and does not offer lead paint testing. Professional lead paint inspectors need specific licenses to perform these inspections, which not all home inspectors have. If you suspect lead paint in the home you are about to purchase, you will need to pay separately to have that done. If the findings come back positive, you may be able to negotiate with the buyer to cover the cost of the removal.

Structural problems with the foundation or roof, water damage, and significant plumbing or electrical issues are all considered major red flags in a home inspection. Of these, a structural problem related to the foundation is often the most severe. Foundation repairs are typically the most expensive and intrusive to carry out, averaging around $5,000 but sometimes reaching up to $16,000. Because these problems can pose safety risks and be costly to fix, you should ask your inspector detailed questions about any identified issues. You will need to carefully consider how major problems affect what you’re willing to pay for the home, or if you want to proceed with the sale at all.
