Home Inspection Checklist
Complete Guide to Every System Inspectors Check
Wondering what inspectors actually check during a home inspection? This complete checklist covers every major system and component inspectors examine in Arizona homes.
Whether you’re a first-time buyer preparing for inspection day or a seller getting your home ready, understanding the inspection checklist helps you know what to expect and what questions to ask.
What’s on a Home Inspection Checklist?
A professional home inspection in Arizona covers 11 major systems and components. Here’s the complete breakdown:
1. Roof & Gutters
What inspectors check:
Arizona roofs take a beating from intense UV exposure, so age is critical. Most asphalt shingle roofs last 15-20 years in Arizona’s heat—yours might be near replacement.
2. Foundation & Structure
Arizona’s expansive clay soils can cause foundation movement. Minor cracks are normal, but diagonal or step cracks warrant a structural engineer’s opinion.
3. HVAC System
In Arizona, A/C is non-negotiable. A 15+ year old unit will likely need replacement soon. Check the condenser for corrosion from desert dust.
4. Electrical System
Learn more about what electrical issues inspectors commonly find in Arizona homes—and why they matter for your safety.
5. Plumbing System
Arizona’s hard water can corrode pipes faster than other regions. Homes with original galvanized plumbing may face replacement costs.
6. Windows, Doors & Frames
Arizona’s intense heat makes windows critical for efficiency. Dual-pane windows with broken seals cost money in wasted A/C.
7. Attic & Ventilation
8. Interior Walls, Ceilings & Floors
9. Built-in Appliances
Note: Appliances are often seller items and may not be included in the inspection depending on the agreement.
10. Thermal Imaging (Advanced Detection)
Professional thermal imaging cameras reveal what the naked eye can’t see—hidden moisture, electrical hot spots, and insulation gaps.
What Inspectors DON’T Check
Important: Standard home inspections have limits:
- ❌ Pest or termite inspection (requires separate specialists)
- ❌ Radon testing (separate test, though inspectors may recommend it)
- ❌ Mold testing (visual assessment only)
- ❌ Environmental hazards like lead or asbestos
- ❌ Swimming pools or spas (often require specialists)
- ❌ Septic systems in depth (visual only)
How to Use This Checklist
For buyers: Print this checklist and bring it to your inspection. Ask the inspector to explain any issues they find.
For sellers: Walk through with this checklist and address obvious issues before putting your home on the market. Fixing problems proactively looks better than having them discovered during inspection.
For homeowners: Use this as an annual maintenance guide. Check your roof, HVAC filters, and drainage regularly.

Common Arizona-Specific Issues
Arizona homes face unique challenges:
- UV damage: Roof, siding, and caulk deteriorate faster in intense desert sun
- Hard water: Mineral buildup in pipes and water heaters reduces efficiency
- Dust: A/C units and ductwork collect desert dust; filters need frequent replacement
- Monsoons: Water intrusion and foundation stress from heavy rains
- Expansive soil: Clay soils expand/contract, stressing foundations
