Key Takeaways
- Properties with 5+ units require a PCA (ASTM E2018-15), not a home inspection—it includes RUL, reserves, and ADA compliance.
- The four-level severity system (Safety Hazard, Major Deficiency, Minor Deficiency, Maintenance Item) prioritizes all findings.
- Seven major building systems are evaluated: structure, envelope, HVAC, plumbing, electrical, fire safety, and site.
- PCA costs $5,000-$25,000 but prevents far larger surprises post-closing.
Property inspections translate abstract due diligence checklists into tangible, quantified findings about a building's physical condition. The inspection determines what works, what does not, what will fail soon, and how much it will cost to repair or replace. This lesson introduces the inspection framework, the distinction between residential and commercial property condition assessments, and the severity scoring system used to prioritize findings.
Home Inspection vs. Property Condition Assessment
Residential properties (1-4 units) are evaluated through a home inspection following ASHI (American Society of Home Inspectors) or InterNACHI standards. The inspector provides a narrative report with photos covering all major systems. Commercial and multifamily properties (5+ units) use a Property Condition Assessment (PCA) following ASTM E2018-15 standards. The PCA is more comprehensive: it estimates remaining useful life (RUL) for every major building component, calculates a replacement reserve schedule, and provides a Facility Condition Index (FCI). The PCA also addresses ADA compliance, fire/life safety, and building code compliance—items not typically covered in a residential inspection. PCAs are performed by engineering firms rather than home inspectors, and costs range from $5,000 to $25,000 depending on property size.
| Feature | Home Inspection | Property Condition Assessment (PCA) |
|---|---|---|
| Standard | ASHI / InterNACHI | ASTM E2018-15 |
| Property Type | 1-4 units | 5+ units / commercial |
| Remaining Useful Life | Not typically estimated | Estimated for all major systems |
| Replacement Reserve | Not included | Full reserve schedule |
| ADA Compliance | Not covered | Included |
| Performed By | Licensed home inspector | Engineering firm |
| Typical Cost | $300-$800 | $5,000-$25,000 |

The Four-Level Severity Scoring System
Every inspection finding should be assigned a severity level to prioritize response. Level 1 - Safety Hazard: conditions that present immediate risk to occupants or require emergency response (exposed wiring, carbon monoxide risk, structural failure, fire code violations). Action: immediate remediation required, may be deal-killer. Level 2 - Major Deficiency: significant defects that require repair within 12 months to prevent further damage or system failure (roof leaks, HVAC failure, plumbing leaks, foundation cracks). Action: negotiate seller credit or repair. Level 3 - Minor Deficiency: cosmetic or functional issues that should be addressed within 1-3 years (aged appliances, cracked tile, minor grading issues, weathered siding). Action: include in CapEx budget. Level 4 - Maintenance Item: routine maintenance or informational observations (caulking, filter replacement, gutter cleaning). Action: add to property management punch list.
Building Systems Overview
A complete inspection evaluates seven major building systems. Structure: foundation, framing, load-bearing walls, beams, and columns. Envelope: roof, siding, windows, doors, insulation, and waterproofing. Mechanical (HVAC): heating, cooling, ventilation, and distribution systems. Plumbing: supply lines, waste lines, water heaters, fixtures, and gas piping. Electrical: service entrance, panels, branch circuits, outlets, switches, and lighting. Fire/Life Safety: fire alarms, sprinkler systems, emergency lighting, and exit signage. Site: grading, drainage, parking, landscaping, and accessory structures. Each system has a defined expected useful life, condition rating criteria, and replacement cost benchmarks.

Common Mistakes to Avoid
Treating all inspection findings with equal priority
Consequence: Resources and negotiation capital are wasted on cosmetic items while critical structural or systems issues are inadequately addressed
Correction: Use severity scoring to prioritize: address critical and significant findings first, defer minor cosmetic items
Ordering only a standard home inspection for a commercial multifamily property
Consequence: Missing commercial-specific concerns like fire code compliance, ADA requirements, and commercial building system assessments
Correction: Engage a commercial property inspector or PCA provider with multifamily experience, not a residential home inspector
