Which of the following is a key goal of building codes?

The primary goal of building codes is to ensure public safety and welfare. These codes establish minimum requirements for the construction and occupancy of buildings to protect the health, safety, and general welfare of the public. They cover various aspects such as structural integrity, fire safety, accessibility, and sanitation. By adhering to these codes, construction practices are regulated to minimize risks associated with building failures, accidents, or other hazards that could harm occupants or the community.

The other options do not represent the main aims of building codes. For example, increasing construction costs can be a consequence of more stringent standards but is not a primary objective. Standardizing decorative elements or promoting specific architectural styles may have value in certain contexts, yet these aspects are not the focus of building codes, which are about safety and functionality rather than aesthetics. Thus, ensuring public safety and welfare remains the cornerstone of building codes.
