Residential Building Inspector Practice Exam

What type of door must be provided for each dwelling?

1. Sliding door

2. Side hinged door

3. Bi-fold door

4. Roll-up door

The correct answer is: Side hinged door

A side hinged door is typically required for each dwelling as it provides a standard method of egress and ensures accessibility in compliance with building codes. This type of door allows for easier movement in and out of the dwelling, especially in emergencies, and is commonly used as the main entry point to residences. Side hinged doors can also accommodate various designs and materials, enhancing both security and aesthetic appeal. Sliding doors, bi-fold doors, and roll-up doors, while functional in certain contexts, do not meet the universal requirements for residential entryways. For instance, sliding doors may not provide the same level of accessibility, especially for individuals with mobility challenges. Bi-fold doors might not offer adequate security for an entry point, and roll-up doors are more often used in commercial settings or garages rather than as primary entrances to homes. Therefore, a side hinged door remains the most appropriate and widely mandated option for residential applications.
