\n\texisting structures. This separate set of regulations is called the Rehabilitation Subcode and has two
\n\tpurposes: 1) to remove regulatory barriers that posed unreasonably high costs, and 2) to maintain health
\n\tand safety standards found in the existing code for new buildings.
\n\tThe Rehabilitation Subcode is the first comprehensive set of code requirements for existing buildings. It is
\n\ta stand-alone subchapter and, therefore, it contains all the technical requirements that apply to a
\n\trehabilitation project.
The Rehab Subcode is divided into parts that are quite different from the codes for new construction. There
\n\tare three major sections that define the types of projects: Rehabilitation, Change of Use, and Additions.
\n\tWithin the Rehabilitation section there are four Categories: repair, renovation, alteration, and
\n\treconstruction. These categories relate to the extent of the work undertaken. Finally, within each category
\n\tthere are five Sets of Requirements: products and practices; materials and methods; new building
\n\telements; basic requirements; and supplemental requirements.
\n\tThe Rehab Subcode also includes an introductory section than is usually included in regulations.
\n\tThe introduction sets the stage for the requirements and is designed as a user-friendly summary. It is not in
\n\tstrict code language and cannot be cited as a code requirement
