California IDEX Practice Exam

The basic separation between occupancies in a mixed occupancy building is determined by...

1. Occupant preference.

2. Building height.

3. Using the CBC 508.3.3 Table.

4. Exterior color scheme.

The correct answer is: Using the CBC 508.3.3 Table.

The correct answer centers on the regulation provided in the California Building Code (CBC) regarding mixed occupancy buildings. Section 508.3.3 of the CBC outlines the requirements and standards for how different types of occupancies can coexist within a single building. This section specifically addresses separation distances and construction types necessary to ensure safety, fire protection, and accessibility among various occupancies. The reliance on a regulatory table, such as CBC 508.3.3, highlights the systematic approach dictated by building codes. This ensures that any new construction adheres to established safety protocols based on empirical data, not personal preferences or aesthetic choices. In contrast, occupant preference does not provide a safety standard and might lead to variances that could compromise safety. Building height can influence occupancy classification but isn’t primarily responsible for determining the necessary separations. Finally, an exterior color scheme is purely aesthetic and has no bearing on occupancy separation requirements.
