HUD Structural and Mechanical Systems Flashcards

Under HQS, what is the standard for an 'adequate' electrical supply in a dwelling unit?

Answer: A wiring system free of hazardous conditions with sufficient outlets in each room

HQS focuses on safety and functionality — the electrical system must be free of hazardous conditions and provide sufficient outlets so occupants don't rely on extension cords as permanent wiring.

An inspector notes that the basement of a HUD-assisted property has standing water after a recent rain. What is the structural concern?

Answer: Potential foundation undermining, efflorescence, and structural damage to sill plates and joists

Basement water intrusion can undermine foundations, cause wood rot in sill plates and joists, and create mold conditions — all structural and health safety concerns under HQS.

What condition related to chimneys must a HUD inspector specifically evaluate during an inspection?

Answer: Whether the chimney is structurally sound and free of obstructions that could prevent proper venting of combustion gases

Inspectors must evaluate chimney structural integrity and freedom from obstruction because blocked or damaged chimneys can cause carbon monoxide to back-draft into the living space.

During a HUD inspection, the inspector finds aluminum branch-circuit wiring in a home built in 1973 connected to devices not rated for aluminum. What hazard does this present?

Answer: Fire hazard due to loose connections caused by aluminum's expansion and contraction properties

Aluminum branch wiring connected to non-aluminum-rated devices is a fire hazard because aluminum expands and contracts differently than copper, causing loose connections that can arc and ignite.

What is the minimum required header size over a 6-foot wide window opening in an exterior load-bearing wall under standard residential structural practice applicable to HUD inspections?

Answer: Double 2×8 or equivalent engineered lumber

A 6-foot opening in a load-bearing exterior wall requires a substantial header, typically a doubled 2×8 or larger (or engineered equivalent), to transfer the load around the opening.

Under HUD HQS, what is required of handrails on interior stairs with four or more risers?

Answer: At least one graspable handrail on stairs with four or more risers

HQS requires at least one graspable handrail on interior stairs with four or more risers to prevent falls, regardless of occupant age.
