Manufactured homes built before 1976 have less of which characteristic than those of current construction?

• A. Content load
• B. Fire resistance
• C. Building restrictions
• D. Lightweight construction

Answer: (B)

Fire resistance. Manufactured homes built before 1976 were not required to meet the fire-resistance standards that came with later codes, so they generally used lighter, more combustible materials and fewer fire-rated assemblies. That means these older homes could burn and falter more quickly, offering less time for occupants to escape. After 1976, the HUD code introduced fire-resistant requirements for interior finishes, ignition resistance, and fire-rated assemblies, which modern manufactured homes must meet, making them more fire-resistant than their pre-1976 counterparts. The other options don’t capture this safety-related difference as accurately; while construction methods and regulations have evolved, the standout distinction in terms of fire safety is the level of fire resistance.
