✍️ Sample CHI Questions & Answers
1. A home inspector identifies open step flashing where a roof plane meets a sidewall. What is the primary risk of this deficiency?
Open or improperly lapped step flashing creates a direct pathway for wind-driven rain to enter the wall-to-roof junction and damage sheathing, insulation, and interior finishes.
2. During lease negotiations, a tenant requests a 'co-tenancy clause.' What protection does this provide?
A co-tenancy clause allows tenants—especially retailers—to reduce rent or terminate the lease if an anchor tenant departs, reducing customer traffic.
3. What is the purpose of an anti-siphon valve (vacuum breaker) on an outdoor hose bib?
Vacuum breakers prevent backflow by stopping negative pressure from siphoning potentially contaminated water back into the drinking water supply.
4. An inspector observes that a sump pump discharge line exits the home and terminates 18 inches from the foundation. What should be recommended?
Discharging sump water too close to the foundation allows it to percolate back into the soil and re-enter the sump, creating a continuous pumping cycle and potential foundation moisture issues.
5. Which component of the HVAC system compresses refrigerant gas?
The compressor is a vital part of the HVAC cycle that pressurizes refrigerant and helps move it through the system.
6. A home inspector reviewing a property for valuation purposes notices deferred maintenance. How does this typically affect market value?
Deferred maintenance signals future repair costs to buyers and appraisers, typically resulting in a downward adjustment to market value.
