HUD Structural and Mechanical Systems Flashcards

During a HUD inspection, an inspector observes significant sagging in a floor joist spanning 14 feet. What is the primary concern?

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.

What is the minimum required exhaust ventilation for a kitchen range hood in HUD-assisted housing under mechanical standards?

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.

A HUD inspector finds that a gas furnace flue pipe has a disconnected joint inside a living area. This is classified as:

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.

Under HUD housing standards, what is the required minimum water pressure at fixtures in an inspected unit?

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.

Which roof condition would a HUD inspector document as an immediate structural deficiency?

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.

A HUD inspector finds that the water heater temperature-pressure relief (TPR) valve lacks a discharge pipe. What is the hazard?

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.
