📈 Factors That Affect Inspection Cost

📐 Square Footage

Primary cost driver. Larger homes = more time = higher cost. Typically $0.18-$0.25 per sq ft.

🏚️ Home Age

Older homes (pre-1980) often have outdated wiring, plumbing, or hazardous materials requiring extra scrutiny.

📍 Location

Urban areas with high cost of living charge 15-30% more than rural areas.

🏢 Property Type

Condos cost less (no roof/exterior), while multi-family properties cost more due to multiple systems.

Frequently Asked Questions

The national average for a home inspection is $300-$450, but costs range from $200 for small homes under 1,000 sq ft to $500-$800+ for large homes over 3,000 sq ft. Factors affecting price include square footage, home age, property type, location, and any additional inspections like radon or mold testing.

The biggest red flags include: foundation issues (cracks, water intrusion, settling), roof damage requiring replacement, electrical panel problems (especially Federal Pacific or Zinsco panels), evidence of water damage or mold, structural issues like sagging floors or cracked walls, and HVAC systems at end of life. These can indicate costly repairs ranging from $5,000 to $50,000+.

Most inspectors charge $0.18-$0.25 per square foot, with a base rate of $250-$350 for homes up to 2,000 sq ft. Add $25-$50 for each additional 500 sq ft. Factor in premiums for older homes (+$50-$200 for pre-1980), multi-story properties, and your local market. Additional inspections like radon ($125-$225) or termite ($75-$150) are charged separately.

A standard inspection covers: roof and attic, foundation and structure, exterior (siding, windows, doors), plumbing systems, electrical systems, HVAC (heating, ventilation, air conditioning), interior (walls, ceilings, floors), insulation, ventilation, and built-in appliances. It does NOT typically include radon, mold, termites, sewer lines, pools, or specialized testing.

Yes, in many cases. Radon testing ($125-$225) is recommended for all homes—radon is the #2 cause of lung cancer. Mold inspection ($250-$350) is wise if you see water stains or smell musty odors. Termite inspection ($75-$150) is essential in southern states. Sewer scope ($150-$300) is smart for older homes with mature trees near sewer lines.

A typical home inspection takes 2-4 hours depending on the home's size. A 1,500 sq ft home takes about 2-2.5 hours, while a 3,000+ sq ft home may take 3-4 hours or more. Add 30-60 minutes for each additional service like radon or termite testing. Buyers are encouraged to attend and ask questions during the inspection.

🏠 Disclaimer: These are estimated costs based on national averages. Actual prices vary by location, inspector experience, and specific property conditions. Always get quotes from multiple certified inspectors (ASHI or InterNACHI members recommended) before making a decision.
