Many things can cause a home to “fail” an inspection, meaning significant issues are found. Here’s a breakdown of common culprits:
Major Structural Issues
- Foundation Problems: Cracks (especially large or horizontal ones), settling, bowing walls, or water damage can indicate serious structural problems.
- Roof Issues: Leaks, damaged or missing shingles, improper flashing, or a sagging roof structure can be costly to repair.
- Framing Problems: Issues with the home’s framing, such as sagging floor joists or damaged support beams, can compromise structural integrity.
Major System Problems
- Electrical System: Outdated wiring (knob-and-tube), insufficient amperage, faulty wiring, or a damaged electrical panel are safety hazards.
- Plumbing System: Leaks, low water pressure, outdated or damaged pipes (especially galvanized steel or polybutylene), or sewer line issues can be expensive to fix.
- HVAC System: An aging or malfunctioning furnace, air conditioner, or water heater can be a major expense. Ductwork problems can also affect efficiency.
Water Damage and Moisture
- Leaks: Roof leaks, plumbing leaks, or leaks around windows and doors can lead to significant water damage.
- Mold: Mold growth is often a result of moisture problems and can be a health hazard.
- Poor Drainage: Improper grading or clogged gutters can cause water to pool around the foundation, leading to water intrusion.
Safety Issues
- Asbestos: Asbestos is a hazardous material that was commonly used in building materials before the 1980s.
- Lead Paint: Lead paint is also a health hazard, especially for young children.
- Radon: Radon is a naturally occurring radioactive gas that can enter homes through cracks in the foundation.
- Carbon Monoxide Detectors and Smoke Detectors: Missing or non-functioning detectors are a safety concern.
Other Common Issues
- Pest Infestations: Termites, carpenter ants, rodents, or other pests can cause significant damage to a home.
- Building Code Violations: Renovations or additions that were not done to code can be a problem.
- Windows and Doors: Broken or damaged windows and doors can lead to drafts, energy loss, and security concerns.
Important Notes
- “Failing” is Subjective: There’s no official “failing” grade for a home inspection. The report simply outlines the condition of the home.
- Negotiation: Issues found during the inspection can be negotiated with the seller. You may be able to ask them to make repairs, provide a credit at closing, or reduce the purchase price.
- Walk Away: In some cases, if significant problems are found, you may choose to walk away from the deal.
It’s important to remember that every home has some imperfections. A home inspection is meant to identify major issues that could be costly or dangerous.
