Babylonian Code of Hammurabi Introduction to Building Codes Civil Engineering and Architecture Unit 2 – Lesson 2.3 – Residential Design Babylonian Code of Hammurabi 1780 BC “If a builder build a house for someone and does not construct it properly, and the house which he built fall in and kill its owner, then that builder shall be put to death.” The first known building code was the Code of Hammurabi which dates back nearly 4000 years. The code included hundreds of laws which were written on stone tablets and displayed in Babylon’s temple of Marduk. Some of the laws dealt with building construction, such as this one.

Introduction to Building Codes Civil Engineering and Architecture Unit 2 – Lesson 2.3 – Residential Design ICC Codes International Residential Code (IRC) International Building Code (IBC) International Mechanical Code International Plumbing Code International Energy Conservation Code ICC Electrical Code Others We will use the IRC for the Affordable Home Project. When you work on a commercial project, you will use additional ICC codes, including the IBC, the International Plumbing Code, and the International Energy Conservation Code.

International Residential Code for One- and Two-Family Dwellings (IRC) Introduction to Building Codes Civil Engineering and Architecture Unit 2 – Lesson 2.3 – Residential Design International Residential Code for One- and Two-Family Dwellings (IRC) Addresses design and construction of one- and two-family dwellings and townhomes Local municipalities can adopt the IRC but may publish modifications Modifications and specifications are generally published on the Internet for all to reference Project Lead The Way, Inc.

International Residential Code Introduction to Building Codes Civil Engineering and Architecture Unit 2 – Lesson 2.3 – Residential Design International Residential Code IRC applies to homes consisting of three stories, or less, above grade Covers conventional residential construction Covers all home components and systems Structural systems Thermal insulation Mechanical systems Plumbing systems Electrical systems Fuel gas systems Fireplaces and chimneys The IRC only applies to residential structures. Design and construction of structures other than one- and two-family homes and townhomes are covered by the IBC. The IRC will not apply to non-conventional residential construction. Other codes will apply to uncommon design and construction. The IRC differs from the IBC in that it is an all-in-one code. For buildings other than those covered by the IRC, different codes apply for different systems – for example, the design and construction of the structural system is specified in the IBC, but the plumbing system must comply with the International Plumbing Code.

International Residential Code Chapter 3 – Building Planning Introduction to Building Codes Civil Engineering and Architecture Unit 2 – Lesson 2.3 – Residential Design International Residential Code Chapter 3 – Building Planning Habitable Space: A space in a building for living, sleeping, eating, or cooking. Bathrooms, toilet rooms, closets, halls, storage or utility spaces, and similar areas are not considered habitable space. The terms habitable space and habitable room are used often in Chapter 3.

International Residential Code Chapter 3 – Building Planning Introduction to Building Codes Civil Engineering and Architecture Unit 2 – Lesson 2.3 – Residential Design International Residential Code Chapter 3 – Building Planning Section R303 – Light, Ventilation, and Heating Section R304 – Minimum Room Areas Section R310 – Emergency Escape and Rescue Openings Section R311 – Means of Egress The IRC is over 800 pages long. Architects and engineers who design and build homes are well versed in all of the code requirements. However, we don’t have time to learn all of the requirements contained in the IRC. For the Affordable Housing Project, we will concentrate on Chapter 3 of the IRC – Building Planning. We will touch on only a few of the requirements – there is much more to learn. Be sure that students have a copy of the International Residential Code Summary. Go over each code requirement as a group and discuss how it will affect the design of their affordable home.
