Which code is primarily related to new construction but also includes provisions for existing buildings?

The Building Code is primarily related to new construction because it sets the minimum safety standards for building design and construction practices that ensure structural integrity, fire safety, accessibility, and overall health and safety standards. These codes provide guidelines for materials, methods, and practices used in building projects.

In addition to its focus on new construction, the Building Code often includes provisions that apply to existing buildings. These provisions may address issues such as modifications, renovations, or alterations to ensure that older structures comply with current safety standards when they undergo changes. As such, the Building Code serves as a comprehensive framework that governs both the construction of new buildings and the necessary requirements for maintaining and updating existing facilities.

The Housing Code, Residential Code, and Historical Preservation Code focus on more specific aspects of building use, occupancy, and preservation and may not encompass the broader scope of new construction and existing building provisions as thoroughly as the Building Code does.
