About This Book
The 2015 International Residential Code (IRC) is a model rulebook establishing minimum safety, health, and energy standards for building or remodeling homes and townhouses up to three stories tall.
What It Covers
The IRC consolidates multiple building trades into a single volume:
- Building: Foundations, walls, floors, and roofs
- Plumbing: Water supply, pipes, and drains
- Mechanical: Heating, ventilation, and air conditioning
- Fuel Gas: Gas lines and appliance installation
- Electrical: Wiring, outlets, and lighting
- Energy: Insulation and windows
How It Works
- Creation: The International Code Council (ICC) writes and updates the code every three years to reflect safety improvements and new building methods.
- Adoption: Local governments must vote to adopt the code before it takes effect in their jurisdiction.
- Local Amendments: Governments often modify the code to account for local climate or soil conditions.
