Up-To-Date Building Codes Support Safe, Sustainable and Resilient Communities

Building codes represent a highly cost-effective strategy to help protect communities from the risks posed by natural and man-made events. The congressionally-established National Institute of Building Sciences (NIBS) found that adopting and enforcing the 2018 International Building Code (IBC) and International Residential Code (IRC) provide communities with an $11 benefit for every $1 invested.  These benefits represent avoided casualties, property damage, business interruptions, first responder expenses, and insurance costs, and are enjoyed by all building stakeholders – from developers, titleholders, and lenders, to tenants and communities. The report also found that retrofitting structures to current codes’ flood mitigation requirements can provide $6 in mitigation benefits for every $1 invested and that retrofitting structures to the Code Council’s Wildland-Urban Interface Code could provide $2 to as much as $8 in mitigation benefits for each $1 invested.

Up to Date Building Codes Mitigate Risk – Additional Research

A number of studies demonstrate the value of up to date building codes as mitigation measures against natural hazards and the cost effectiveness of these efforts. One study found buyers paid an almost 6 percent premium for homes with hurricane shutters on Galveston Island, TX. Another study found resale premiums near 4 percent for homes with tornado shelters. Additional research has found that enacting enhanced codes in tornado country had no effect on the price per square foot or home sales.

Additional studies confirm that the adoption and implementation of current model building codes is one of the nation’s best defenses against the natural hazards. For example:

  • An initial release from an ongoing FEMA analysis found that Florida and California's consistent adoption of the I-Codes (and their hazard mitigation provisions) since 2000 will provide long-term average future savings of $1 billion a year.
  • The 2019 FEMA Mitigation Assessment Team (MAT) report following Hurricane Harvey found that National Flood Insurance Program (NFIP) regulations reduced average claim payments by almost half and following modern code requirements reduced the average claim payments by an additional 90%.
  • In the ten years following Florida’s adoption of a statewide building code, the code’s adoption and application reduced windstorm actual losses by as much as 72 percent.
  • Effective and well‐enforced building codes in Missouri reduced hail damage to homes by 10 to 20 percent on average.
  • Although building code adoption alone generates enormous mitigation benefits, code enforcement is equally important. FEMA quantified the cost of Dade County Florida’s inadequate code enforcement as a quarter of the $16 billion in insured losses from Hurricane Andrew in 1992. Researchers found similar results about 15 years later: that implementing building codes at the local level by ensuring proper staffing, training, and certification provides an additional loss reduction value on the order of 15 to 25 percent.

What Edition of the Code is My Community On?

Building codes are adopted at the state and/or local level in the United States. The edition in place in a community varies widely. The Federal Alliance for Safe Homes’ (FLASH) InspectToProtect.org allows users to look up the codes applicable to a given residential address. FEMA's tracker of the adoption of hazard resistant building codes at the state and local levels across the U.S. can be viewed here. You can also view the Building Code Effectiveness Grading Schedule (BCEGS) National Building Code Assessment Report here for an in depth analysis of state code enforcement efforts. The below map tracks the adoption status of the most recent edition of the International Building and Residential Codes, including where adoptions are effective, where adoptions have a future effective date, and where the code is under review.

How Do States and Localities Adopt Building Codes?

The process for adoption at the state and local level varies, but typically allows for some level of public engagement. Learn how states adopt the International Codes (I-Codes). Sample ordinances are available to help communities get started in the adoption process.

How are Building Codes Developed?

The I-Codes are the most widely used and adopted set of building safety codes in the world. These model codes developed through a consensus process organized by the International Code Council that allows all interested parties to recommend changes. The final outcomes are voted on by state and local government officials that are charged with protecting health, safety and welfare in their communities. The I-Codes are updated every three years.

Federal Support for Leveraging Codes in Promoting Resilient Communities

On August 14, 2019 the Mitigation Framework Leadership Group (MitFLG), chaired by the Federal Emergency Management Agency (FEMA), released the National Mitigation Investment Strategy (NMIS), a unified national strategy on mitigation investment that reduces risks posed by natural hazards and increases the nation’s resilience to disasters. The MitFLG is composed of 14 federal agencies and departments as well as state, tribal and local officials and is charged with coordinating the strategy’s implementation. The Strategy makes several recommendations concerning the use, enforcement, and adoption of building codes: “[a]rchitects, engineers, builders, and regulators should use the latest building codes for the most up-to-date requirements for structural integrity, mechanical integrity, fire prevention, and energy conservation,” “trained, certified professionals [should] handle building inspections and code administration,” and “[u]p-to-date building codes and standard criteria should be required in federal and state grants and programs. The NMIS devotes a section to encouraging communities to adopt and enforce up-to-date building codes.

The strategy’s focus on codes as a keystone mitigation investment strategy aligns with FEMA’s current strategic plan, and highlights that up-to-date building codes help communities survive, remain resilient, and continue to provide essential services after a disaster occurs. The NMIS notes that despite extensive research on codes’ mitigation benefits, only 32 percent of disaster-prone jurisdictions have adopted disaster-resistant building codes.

One of the most critical recommendations in the strategy with immediate implications is “Up-to-date building codes and standard criteria should be required in federal and state grants and programs.” To the Code Council’s knowledge, FEMA is currently the only federal agency that requires adherence to the latest codes and standards in a grant program. This recommendation has widespread existing support, including from bipartisan former FEMA administrators. It also builds on recent work by the Administration and Congress to leverage codes’ mitigation benefits. Twice last year – through the Bipartisan Budget Act and Disaster Recovery Reform Act – Congress passed, and the President signed into law, measures that incentivize the adoption and application of modern model building codes through enhanced federal cost shares for post-disaster rebuilding, new grants for states and localities both pre- and post-disaster, and by making pre-disaster mitigation grant applicants more competitive based on their adoption of up to date model codes.
