What Is a 4-Point Inspection (and When Do You Need One)?

Understand 4-point inspections—roof, electrical, plumbing, and HVAC—and when Chicago and Northern Illinois homeowners or insurers require them.

A 4-point inspection examines four major systems—roof, electrical, plumbing, and HVAC—to assess insurability and risk. While a full home inspection looks broadly at all accessible systems, a 4-point is focused and often requested by insurance companies for older homes.

Roof. The inspector documents the roof material, general condition, and estimated remaining life. Insurers pay attention to roofs because deterioration increases the likelihood of claims from leaks and interior damage.

Electrical. The panel type, wiring, visible safety issues, and presence of modern protections (AFCI/GFCI) are noted. Older electrical systems or clear safety hazards can lead insurers to require an upgrade.

Plumbing. Visible supply lines, drain materials, water heater condition, and evidence of leaks are assessed. Certain pipe materials (e.g., polybutylene) have known failure histories and can affect insurability.

HVAC. Age, operation, and ventilation of heating and cooling systems are evaluated. Poorly maintained or unsafe combustion appliances can be a liability concern.

When Insurers Require One. Commonly for homes older than 25–30 years, during policy renewal, or when a home has an elevated risk profile. A 4-point can be less expensive and quicker than a full inspection, but it does not provide the comprehensive picture a buyer typically needs.

Limitations & Recommendations. If a 4-point raises concerns, homeowners may be advised to obtain a full inspection or specialized evaluations (electrician, structural engineer). Envision Property Inspections provides thorough 4-point inspections and clear guidance on next steps.

Conclusion. A 4-point inspection is an efficient way to evaluate insurability of core systems—especially relevant for older Chicago-area homes where system age and wear are common variables in underwriting.
