Final answer:
In a building with multiple occupancy types, regulations of the most stringent occupancy must be met when there are conflicting or additional safety and health concerns. This includes adherence to strict building codes and avoiding discriminatory practices such as spot zoning based on race or religion.
Step-by-step explanation:
When a building has multiple types of occupancies, the requirement to meet the standards of the most stringent occupancy classification typically applies when different uses impose conflicting or additional safety, health, or welfare concerns. For instance, if part of a building is used for residential purposes and another part for industrial activities, the overall building codes and regulations must comply with the more demanding safety requirements due to potential hazards associated with the industrial use. Compliance with building codes ensures the safety and well-being of occupants and includes various aspects such as restrictions on accessory buildings, building setbacks, size and height of buildings, and the number of rooms among others.
It's also important to note that spot zoning, which allows for different uses within a specific area, must be reasonable and cannot be based on discriminatory practices such as race or religion. Adherence to these guidelines helps maintain community standards and safeguards against hazards posed by certain types of occupancies.
