International Code Council Unveils 2024 International Plumbing Code and 2024 International Mechanical Code 

Washington, D.C. – The International Code Council has announced the release of the 2024 International Plumbing Code (IPC) and the 2024 International Mechanical Code (IMC) from the forthcoming 2024 editions of the International Codes® (I-Codes). The 2024 IPC and IMC will be the first codes among the 2024 I-Codes to undergo substantial formatting changes to improve the user experience and better align print and PDF versions of the I-Codes with the Code Council’s Digital Codes® content.   

The 2024 IPC improves public health through enhanced waste management requirements and plumbing system resilience to natural hazards. It also advances community sustainability through new water conservation measures, while assuring building accessibility through the integration of the updated ICC A117.1 Accessibility Standard, making the IPC the most comprehensive plumbing code available. 

Some of the updates to the 2024 IPC include:  

  • Provisions added for support of buried piping beneath buildings where expansive soil conditions exist.  
  • Option added for vacuum testing of Drain Waste Vent (DWV) piping.  
  • Showerhead flow limited to 2.0 gallons per minute (gpm) with performance complying with high efficiency requirements.  
  • Standards added for chemical waste piping and fitting materials.  

  The 2024 IMC establishes minimum regulations for mechanical systems using prescriptive and performance-related provisions.  

Important changes from the 2021 IMC to the 2024 IMC include:  

  • Requirements prohibiting the use of domestic ductless range hoods in Groups I-1 and I-2 were removed.    
  • Group A2L and B2L refrigerant requirements have been added. 
  • Leak detection monitoring with alarm requirements have been added where the discharge from safety relief valves is not “readily visible” to occupants.  
  • Outside air requirements for dwelling units have increased. 
  • Requirements for exhaust system common ducts serving separate dwelling units have been added requiring the common duct or shaft to be maintained at a negative pressure at all times.  

  As part of the Code Council’s digital transformation strategy, the 2024 IPC and IMC are the first I-Codes to include new and improved formatting to align with the Code Council’s Digital Codes® content, which will be implemented within the 2024 I-Codes and all future I-Codes. These enhancements were developed and implemented based on feedback from print and digital I-Codes users and aim to improve user experience, with a modern look that improves readability.   

 Notable enhancements to the latest codes include additions such as QR codes next to the revised codes for easy reference, and a pilot program of a Near Field Communication (NFC) tag to enhance user access to I-Codes support, increase security and improve the product owner registration process.   

For more details about these changes, please visit our dedicated webpage.

International Code Council Launches Global Capacity Building Initiative

Washington, D.C. – In response to the continued demand for new solutions, the International Code Council has introduced the Building Capacity for Resilient and Sustainable Buildings initiative. This initiative emphasizes the importance of effective building regulatory systems to ensure that the intended benefits of building regulations are achieved.

Through this effort, the Code Council aims to help global communities reach their resilience and decarbonization goals by providing resources and tools to support the effective implementation and enforcement of building codes. It calls on governments, corporations and organizations to assist countries in developing, adopting and implementing energy and hazard-resistant codes.

Building Capacity for Resilient and Sustainable Buildings is a recognized initiative of the Buildings Breakthrough, launched and co-led by France (Ministry of Ecological Transition) and the Kingdom of Morocco (Ministry of National Territory Planning, Land Planning, Housing and City Policy), and coordinated under the umbrella of the UNEP-hosted Global Alliance for Buildings and Construction (GlobalABC). The Buildings Breakthrough is a call to all countries to help accelerate the transition to near-zero emission and resilient buildings by 2030. 

Initial partner organizations of the initiative include Architecture2030, the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), GlobalABC, HOK, the International Building Quality Centre, ResALLience, +LAB Architects, and Saint-Gobain North America.

The importance placed on capacity building will be a major focus of the Code Council’s participation at the upcoming UN Climate Change Conference, COP28, in Dubai, from November 30-December 12. Learn more about the Code Council’s participation at COP here.

The Building Capacity for Sustainable and Resilient Buildings Program is seeking further signatories from organizations, governments and corporations. To sign on as a partner organization, please contact Joe Sollod, Code Council Sustainability, Resilience and Innovation Associate, at jsollod@iccsafe.org

Preparing for Hurricane Idalia

The International Code Council is monitoring Hurricane Idalia as it rapidly intensifies and moves northward to take aim at Florida, Georgia and South Carolina tomorrow, August 30, 2023. Idalia is forecasted to be a strong Category 3 hurricane with forecasted winds of 125 mph or more. Life-threatening storm surge is possible along much of the Florida west coast, with areas between the Aucilla River and Yankeetown potentially experiencing destructive waves of 10 to 15 feet above ground level. Florida residents in affected areas should listen to advice given by state and local officials, including the Florida Division of Emergency Management.

Hurricane-force winds are possible in the hurricane watch area in west-central Florida beginning this evening, Tuesday, August 29, into Wednesday morning, August 30. Residents in this area should ensure that they have their hurricane plans in place.

For the latest forecast and additional safety information, please visit the National Hurricane Center and the Code Council’s hurricane safety and resources page. 

Managing Your Flood Risk

The Code Council and our partners at the Federal Emergency Management Agency (FEMA) remind everyone that floods can happen anywhere, not just during or after a hurricane. Most homeowners’ insurance does not cover flood damage. Flood insurance is a separate policy that can cover buildings, the contents of a building, or both, so it is important to protect your financial assets including your home, your business and your possessions.

Disaster Recovery Resource for Code Officials 

When disasters strike, codes and standards serve as a baseline for the return to safe, sanitary and habitable buildings. Code officials and their floodplain management counterparts rely on support from emergency managers and community leaders to help secure the critical resources needed to ensure the health, safety and welfare of the community. To that end, FEMA has a disaster policy specifically aimed at providing much-needed assistance for code officials and floodplain managers during disaster response and initial recovery for up to 180 days following a major disaster declaration. Learn how to apply for building code administration and enforcement assistance here. 

This policy, administered under FEMA’s Public Assistance Program, offers reimbursement for critical community functions such as building code administration, code enforcement, floodplain management administration and enforcement, and conducts substantial damage surveys inspections in affected communities. For more information, visit the Code Council’s resource page. 

Mitigation Opportunities

The Code Council and FEMA support community-based mitigation strategies that decrease risk and repetitive loss while increasing a community’s resilience to disasters. As part of those strategies, the adoption and enforcement of building codes has been identified as a federal priority, across FEMA’s BRIC and Hazard Mitigation Grant Programs as well as HUD's Community Development Block Grant disaster recovery and mitigation programs.

Eligible building code adoption and enforcement activities are activities that: 

  • Evaluate adoption and/or implementation of codes that reduce risk. 
  • Enhance existing adopted codes to incorporate more current requirements or higher standards. 
  • Develop professional workforce capabilities through technical assistance and training. 

For more information on the disaster-resistant provisions of the International Codes® or federal mitigation grant programs, contact your Code Council Government Relations Regional Manager or Karl Fippinger, Vice President - Government Relations, Fire and Disaster Mitigation, at kfippinger@iccsafe.org.  

Disaster Response Alliance  

As an aid to community disaster response, the Code Council and the National Council of Structural Engineers Associations (NCSEA) sponsor the Disaster Response Alliance (DRA). The DRA maintains a national database of skilled, trained, and certified building safety professionals who are standing by and ready to assist communities in need.  

The DRA has assembled a cadre of skilled code officials, engineers and others from across the country who are willing to assist with post-disaster safety assessments, building damage assessments, inspections and surge support for other code-related functions. The Disaster Response Alliance brings together skilled, volunteer second responders in one place for easy access and quick mobilization. Federal, state, local, tribal and territorial entities may request assistance directly through the DRA website. 

Interested in becoming a DRA resource? 

The DRA is always looking for volunteers. If you or someone you know is interested in becoming a DRA second responder resource, please visit the Volunteer Now link on the DRA website. Architects, engineers and building safety professionals willing to make a difference during times of disaster are encouraged to apply. The DRA is also looking for individuals with specialized skills, knowledge, or abilities such as plans examiners, permit technicians, and building inspectors. 

 

Update on Maui Wildfires

Update on Maui Wildfires

August 15, 2023

The International Code Council is coordinating with its federal, state, and local partners to help following last week’s devastating Maui wildfires. Tragically, over 99 lives have been lost and that number is expected to continue to rise as more than 1,000 people are still unaccounted for.

The Maui wildfires were catastrophic and fast-moving, consuming more than 2,000 acres and leaving over 2,200 structures damaged or destroyed. The greatest structural loss was among residential dwellings accounting for more than 85% of the damaged or destroyed structures.
