What document may serve as a reference for construction material specifications?

The correct choice is the International Building Code (IBC) because it is a comprehensive set of standards that provides guidelines for construction and material specifications across various building types. The IBC outlines requirements for structural integrity, fire safety, accessibility, and other crucial aspects of building design and construction. This makes it an essential resource for inspectors and builders to refer to when ensuring that materials meet accepted standards and the construction adheres to legal requirements.

While the property deed pertains to ownership and rights related to a specific parcel of land, and the building permit serves as an approval for the intended construction project, neither document specifically addresses material specifications. The construction contract, on the other hand, may include certain specifications agreed upon by the parties involved but can vary widely depending on the details negotiated between the contractor and the property owner. Therefore, for universally applicable standards and codes that focus on construction materials, the IBC is the most authoritative and relevant source.
