HUD Structural and Mechanical Systems Flashcards

A HUD inspector finds that the central air conditioning system is non-functional in July in Phoenix, Arizona. How should this be documented?

Answer: Evaluated based on whether the unit can maintain a safe interior temperature; may be a fail in extreme heat climates

HQS does not universally require air conditioning, but PHAs in extreme heat climates may designate it as a required feature; the inspector evaluates based on local standards and health risk.

Which of the following plumbing conditions is considered a standard (non-life-threatening) HQS fail?

Answer: A corroded but functional pressure relief valve on the water heater

A corroded but still-functional TPR valve is a standard deficiency requiring correction within 30 days; it's not immediately life-threatening unlike a gas leak or sewage backup.

When inspecting a HUD-assisted home, an inspector finds that the exterior foundation has large horizontal cracks. What does this most likely indicate?

Answer: Lateral soil pressure causing structural bowing or failure of the foundation wall

Large horizontal cracks in a foundation wall typically indicate lateral soil pressure that is bowing or shearing the wall — a serious structural deficiency requiring engineering evaluation.

Under HUD standards, what is the minimum insulation R-value required in an attic for a home in a heating-dominated climate zone?

Answer: R-30 to R-38 depending on climate zone

HUD and energy codes require R-30 to R-38 (or higher) in attics for heating-dominated climates; the exact value depends on the specific climate zone designation.

What is the purpose of a 'P-trap' under a plumbing fixture, as evaluated in a HUD inspection?

Answer: To hold water that blocks sewer gases from entering the living space

A P-trap holds a water seal that prevents toxic and odorous sewer gases from entering the living space; a missing or dry trap is a health and safety deficiency.

A HUD inspector finds evidence of active termite infestation in the floor system of an assisted unit. This should be documented as:

Answer: A structural safety deficiency requiring professional pest control and structural evaluation

Active termite infestation is a structural safety concern under HQS because termites can compromise load-bearing members; it requires pest treatment and assessment of existing structural damage.
