Florida Home Inspector Practice Test

✓ Correct Answer: B) Control moisture from soil evaporation

Explanation: The primary purpose of a vapor barrier (typically 6-mil polyethylene plastic) in a crawl space is to prevent moisture from the soil from evaporating into the crawl space. While this does help prevent wood rot (A), control energy efficiency (C), and provide some insulating value (D), these are secondary benefits. The main function is moisture control from ground evaporation, which in Florida's humid climate is especially critical to prevent mold, mildew, and structural damage.

✓ Correct Answer: C) Bedroom receptacles

Explanation: GFCI protection is NOT required for standard bedroom receptacles. GFCIs are required in locations where there is a higher risk of electrical shock due to water: bathrooms (A), kitchen countertop receptacles within 6 feet of a sink (B), all outdoor receptacles (D), garages, crawl spaces, unfinished basements, and laundry areas. Bedroom receptacles do not typically have water exposure and therefore do not require GFCI protection under the National Electrical Code or Florida Building Code.

✓ Correct Answer: B) 1:150 (1 sq ft vent per 150 sq ft attic)

Explanation: The Florida Building Code requires a minimum ventilation ratio of 1:150 when the attic has both upper (ridge/gable) and lower (soffit) ventilation. If there is only one type of ventilation, the ratio increases to 1:300 (D). The 1:150 ratio means for every 150 square feet of attic floor space, you need 1 square foot of net free ventilation area. This helps reduce heat buildup and moisture, which is especially important in Florida's hot, humid climate. Proper ventilation extends roof life and reduces cooling costs.

✓ Correct Answer: B) On top of the tank or within the top 6 inches

Explanation: The TPR valve must be installed on the top of the tank or within the top 6 inches of the tank. This location is required because hot water rises, and the hottest water is at the top of the tank. The valve needs to sense the highest temperature to function properly. The TPR valve is a critical safety device that releases water if the temperature exceeds 210°F or the pressure exceeds 150 PSI, preventing tank explosions. A discharge pipe must extend from the valve to within 6 inches of the floor, terminating in a safe location.

✓ Correct Answer: B) 14 SEER

Explanation: The U.S. Department of Energy requires a minimum SEER rating of 14 for split-system air conditioners in the southeastern United States, including Florida (as of 2023). Previously the minimum was 13 SEER. Higher SEER ratings (15, 16, or higher) indicate more efficient systems that use less energy, which is especially valuable in Florida where air conditioning runs for much of the year. A higher SEER system costs more upfront but saves money on utility bills over time. Many Florida homeowners choose 15-16 SEER systems for optimal efficiency.
