Study Session 1
Chapters 1 and 43-Administration and Referenced Standards
OBJECTIVE: To obtain an understanding of the administrative provisions of the International Residential Code, including the scope and purpose of the code, duties of the building official, issuance of permits, submission of construction documents, inspection procedures, certificate of occupancy and referenced standards.
CODE REFERENCE: Chapters 1 and 43, 2003 International Residential Code
Reference: IRC R101.2
Subject: General Requirements
Code Text: The provisions of the International Residential Code for One- and Two-Family Dwellings shall apply to the construction, alteration, movement, enlargement, replacement, repair, equipment, use and occupancy, location, removal and demolition of detached one- and two-family dwellings and multiple single-family dwellings (townhouses) not more than three stories in height with a separate means of egress and their accessory structures.
Discussion and Commentary: The International Residential Code is intended to regulate the broad spectrum of construction activities associated with residential buildings and structures. The provisions address building planning and construction aspects, as well as energy efficiency, mechanical, plumbing and electrical aspects.
Townhouses regulated under the IRC are not only limited to three stories and provided with individual egress facilities, they must also be designed with open space to the exterior on at least two sides. Each dwelling unit must extend from the foundation to the roof as a single unit.
Topic: Dwelling Units
Reference: IRC R101.2, Exception
Subject: General Requirements
Code Text:Detached one- and two-family dwellings and multiple single family dwellings (townhouses) not more than three stories high with a separate means of egress and their accessory structures shall comply with the International Residential Code.
Discussion and Commentary: Many residential structures are exempt from the requirements of the International Building Code and are regulated instead by the International Residential Code, a separate and distinct document. The IRC contains prescriptive requirements for the construction of detached single-family dwellings, detached duplexes, townhouses and all structures accessory to such buildings. Limited to three stories with individual egress facilities, these residential buildings are fully regulated by the IRC for building, plumbing, mechanical, electrical and energy provisions.
In addition to the general requirements, a townhouse is also limited by definitioin in the IRC. To fall under the scope of the International Residential Code, each townhouse must be a single units from the foundation to the roof, with at least two sides having open space to the exterior.
Topic: Existing buildings
Reference: IRC 101.2,Exception
Subject: General Requirements
Code Text: Existing buildings undergoing repair, alterations or additions, and change of occupancy shall be permitted to comply with the International Existing Building Code.
Discussion and Commentary: As an alternative to IRC Section R102.7 for the regulation of work or an occupancy change in an existing building, the provisions of the International Existing Building Code (IEBC) may be utilized. The IEBC establishes minimum regulations for existing buildings using prescriptive and performance-related provisions. It is founded on broad-based principles intended to encourage the use and reuse of existing buildings while requiring reasonable upgrades and improvements. The IEBC is fully compatible with all of the International Codes published by the International Code Council. The scope of the code addresses various classifications of work including repair, three levels of alterations, change of occupancy, additions, historic buildings and relocated structures.
An important portion of the IEBC is Resource A, which provides guidelines on the determination of fire ratings for archaic materials and assemblies. In addition, IRC Appendix Chapter J, when adopted, addresses a more comprehensive approach to existing buildings than Section R 102.7.
Reference: IRC R102.5
Code Text: Provisions in the appendices shall not apply unless specifically referenced in the adopting ordinance.
Discussion and Commentary: The appendix chapters of the IRC address subjects that are inappropriate portion of the code. Rather, the appendices are optional, with each jurisdiction adopting some or none of the appendix chapters, depending on its needs for enforcement in any given area. There are various reasons why certain issues are placed in the appendix. Often, the provisions are limit- interest. Some appendix chapters are merely extensions of requirements set forth in the body of the code. Others address issues that are often thought of as outside of the scope of a traditional building code. For whatever reason, no appendix chapter is applicable unless specifically adopted.
Appendix A: Sizing and Capaciites of Gas Piping
Appendix B: Sizing of venting Systems Serving Appliances Equipped with Draft Hoods, Category I Appliances, and Appliances listed for Use and Type B Vents
Appendix C: Exit Terminals of Mechanical Draft and Direct Vent Venting Systems
Appendix D: Recommended Procedure for Safety Inspection of an Existing Appliance Installation
Appendix E: Manufactured Housing Used as Dwellings
Appendix F: Radon Control Methods
Appendix G: Swimming Pools, Spas and Hot Tubs
Appendix H: Patio Covers
Appendix I: Private Sewage Disposal
Appendix J: Existing Buildings and Structures
Appendix K: Sound Transmission
Appendix L: International Residential Code Electrical Provisions/National Electrical Code Cross Reference
Appendix chapters not adopted as a prtion of a jurisdiction's building code may still be of value in application of the code. Provisions in the appendices might provide some degree of assistance in evaluating proposed alternative designs, methods or materials of construction.
