HUD HUD Structural and Mechanical Systems 1 — Questions and Answers
Question 1: During a HUD inspection, an inspector observes significant sagging in a floor joist spanning 14 feet. What is the primary concern?
- Cosmetic issue only
- Potential structural failure risk indicating overspanning, rot, or pest damage (Correct answer)
- Normal settlement in older homes
- Sign that the attic needs insulation
Correct answer: Potential structural failure risk indicating overspanning, rot, or pest damage
Significant floor joist sagging indicates a structural deficiency that could lead to failure, caused by overspanning, moisture damage, termite activity, or overloading.
Question 2: What is the minimum required exhaust ventilation for a kitchen range hood in HUD-assisted housing under mechanical standards?
- 50 CFM intermittent or 20 CFM continuous (Correct answer)
- 100 CFM intermittent or 25 CFM continuous
- 150 CFM intermittent or 50 CFM continuous
- 200 CFM intermittent or 100 CFM continuous
Correct answer: 50 CFM intermittent or 20 CFM continuous
HUD and IRC mechanical standards require kitchen exhaust ventilation of at least 100 CFM intermittent or 25 CFM continuous; however, 50 CFM intermittent is the minimum under older HQS guidance.
Question 3: A HUD inspector finds that a gas furnace flue pipe has a disconnected joint inside a living area. This is classified as:
- A minor maintenance item
- A life-threatening fail requiring 24-hour correction (Correct answer)
- A standard fail requiring 30-day correction
- Acceptable if the furnace is in a closet
Correct answer: A life-threatening fail requiring 24-hour correction
A disconnected furnace flue pipe is a life-threatening deficiency because it allows carbon monoxide to vent directly into the living space, creating an immediate danger.
Question 4: Under HUD housing standards, what is the required minimum water pressure at fixtures in an inspected unit?
- 15 psi
- 20 psi (Correct answer)
- 30 psi
- 40 psi
Correct answer: 20 psi
HUD's HQS requires that water be supplied at adequate pressure; the minimum accepted pressure at fixtures is generally 20 psi to ensure proper operation.
Question 5: Which roof condition would a HUD inspector document as an immediate structural deficiency?
- Granule loss on asphalt shingles
- Missing ridge cap shingles
- Visible daylight through the roof deck boards (Correct answer)
- Moss growth on the north slope
Correct answer: Visible daylight through the roof deck boards
Visible daylight through the roof deck indicates structural failure of the roof system, creating immediate exposure to weather and potential structural collapse risk.
Question 6: A HUD inspector finds that the water heater temperature-pressure relief (TPR) valve lacks a discharge pipe. What is the hazard?
- Increased energy costs
- Risk of scalding or explosive discharge directed at occupants if the valve activates (Correct answer)
- Voided water heater warranty
- Increased risk of pipe corrosion
Correct answer: Risk of scalding or explosive discharge directed at occupants if the valve activates
Without a discharge pipe, a TPR valve activation would spray superheated water or steam directly, potentially scalding occupants; the pipe safely routes discharge to the floor or exterior.
