Question \#18 of 23 Before construction of a new building or the alteration of an existing structure, code enforcement officials issue A) a building permit. B) a building code. C) a variance. D) a certificate of occupancy.

To determine the correct answer to the question regarding what code enforcement officials issue before the construction of a new building or the alteration of an existing structure, let's analyze the options: A) **A building permit** - This is typically required before construction can begin. It ensures that the proposed work complies with local building codes and regulations. B) **A building code** - This refers to the set of regulations that govern building construction and safety standards, not something that is issued for a specific project. C) **A variance** - This is a request to deviate from current zoning requirements, which may be needed in some cases, but it is not a standard issuance before construction. D) **A certificate of occupancy** - This is issued after construction is completed to certify that the building is safe to occupy, not before construction begins. Based on this analysis, the correct answer is: **A) a building permit.**
