PREFACE The purpose of this code is to provide minimum requirements to safeguard life or limb, health, and public welfare and the protection of property as it relates to these safeguards by regulating and controlling the design, construction, prefabrication, equipment or appliance installation, quality of materials, use and occupancy location and repair of detached one-or two-family dwellings, not more than three stories in height. Also the purpose is to further standardize requirements by using a compilation of data from the following national model codes: BUILDING BOCA National Building Code Standard Building Code Uniform Building Code PLUMBING BOCA National Plumbing Code Standard Plumbing Code Uniform Plumbing Code MECHANICAL BOCA National Mechanical Code Code for the Installation of Heat-Producing Appliances Standard Gas Code Standard Mechanical Code Uniform Mechanical Code ELECTRICAL National Electrical Code This code is dedicated to the development of better building construction and greater safety to the public and unifonnity in building laws; to the granting of full justice to all building materials on a fair basis of the true merits of each material; and to development on a sound economic basis for the future growth of our urban areas through unbiased and equitable dealing with building construction. All of the nationally recognized model codes upon which this code is based are comprehensive and flexible and make provision for the use of all safe materials or methods of construction. Consequently, there are construction materials and practices other than listed in this code which are adequate for the purposes intended. These other methods represent either seldom-used systems or performance-type systems which require individual consideration by the professional architect or engineer based on either test data or engineering analysis and are therefore not included herein. The construction methods covered in this code are time tested and therefore do not need additional substantiating data to justify their adequacy. Vertical lines in the margins indicate changes from the 1989 edition except where the entire chapter was revised, a new chapter was added or the change was minor. Where an entire chapter was changed or a new chapter was added, a notation appears at the beginning of that chapter. Asterisks (*) in the margins indicate locations from which the 1989 edition text has either been deleted or relocated. Certain editorial enhancements have been included in this edition. Most notably, tables and figures have been relocated to follow the primary section in which the tables and figures are referenced.
