Building Codes: How Do They Become Law?

A building code is a set of rules that specify the standards for the construction of buildings and non-building structures. Building codes are designed to protect public health, safety, and general welfare. They become law when formally enacted by the relevant governmental or private authority. Building codes vary across jurisdictions, with some developed by government agencies and enforced across the country, while others are developed by local authorities. The process of updating building codes involves studying the causes of building failures and incorporating lessons learned into the codes. While building codes are important for ensuring safety, there is also criticism regarding their impact on construction costs and the negotiation process behind their development.

Building codes are laws that set minimum requirements for the design and construction of buildings

The main purpose of building codes is to protect public health, safety, and general welfare. They cover various aspects of construction, including structural design, sanitation, environmental control, fire prevention, ventilation, lighting, and the use of materials. Building codes also address specific issues such as energy use, plumbing access, and fire escapes, learning from prior failures and disasters to prevent future incidents.

In the United States, building codes are primarily governed by state and local governments. While some states have their own unique codes, others have adopted model codes, such as the International Building Code (IBC) or International Residential Code (IRC). These model codes are developed by organisations like the nonprofit International Code Council (ICC), which incorporates existing consensus building standards created by professional organisations with expertise in relevant fields.

The process of developing and updating building codes involves input from various stakeholders, including builders, manufacturers, building officials, researchers, and safety inspectors. While building codes are essential for establishing minimum standards, critics argue that they can contribute to increased construction costs and housing crises. However, supporters emphasise the importance of public health and safety, and local governments have the flexibility to adopt or modify codes as needed.

Building codes are dynamic and evolve over time, reflecting advancements in technology, changes in climate patterns, and lessons learned from past disasters. They play a crucial role in ensuring the safety and well-being of occupants, adapting to the specific needs and challenges of different regions.

Building codes are enforced by local governments and vary from state to state

Building codes are a set of regulations that dictate the design, construction, and modification of structures within a jurisdiction. They are enforced by local governments and vary from state to state, and even within states. While building codes are now a complex series of rules, they started as a few sentences aimed at preventing fires. For example, the original Boston building code from 1631 outlawed thatched roofs and wooden chimneys.

In the US, building codes are mostly enforced by state and local governments and are based on common draft language, or model codes, which are produced by the non-profit International Code Council (ICC). These model codes are then tailored to the specific needs of a state, county, or city. For example, California's building codes focus on earthquakes, while Florida's include measures to address hurricanes.

The development of modern building codes began in the early 20th century when residents of tenement houses demanded basic sanitation in their housing. The first National Building Code was approved in 1905 and designed to be used as a model for state and local governments when drafting their own codes. During the 1930s, the federal government further modernized the system of housing in the US, and by the 1970s, the majority of building codes were enacted at the local level.

Today, building codes continue to evolve and adapt to new information and technologies. For example, after Hurricane Sandy, New York City created new codes to increase and maintain access to water and electricity in residential buildings. While building codes are important for ensuring safety and health, some critics argue that they contribute to rising construction costs and housing prices.

Building codes are based on common draft language, known as model codes, which are tailored to the needs of a specific state or city

Building codes are a set of rules that specify the standards for the design, construction, and modification of buildings and structures in a particular jurisdiction. They are based on common draft language, known as model codes, which provide a set of minimum requirements for building design, construction, and operation to protect public health, safety, and natural resources. These model codes are then tailored to meet the specific needs of a state, county, or city and are enacted into law by the appropriate governmental or private authority.

Model codes are developed by the nonprofit International Code Council (ICC) and incorporate existing consensus building standards created by professional organizations with expertise in relevant fields. They specify fire safety and evacuation requirements, as well as the level of wind, rain, hail, and other hazards that buildings should be designed to withstand. Model codes also include standards for a diverse array of building elements such as sprinklers, exit signage, structural steel, concrete, and windows.

The process of developing and updating model codes involves input from various committees and organizations. Committees within standards organizations follow guidelines set by the American National Standards Institute (ANSI) to ensure balanced representation among builders, manufacturers, building officials, researchers, and other interested parties. The ICC also holds public hearings where anyone can provide testimony for or against a proposed change to the model code.

Once the model codes are finalized, they are adopted by state and local lawmakers and become the basis for inspecting and evaluating the safety of structures within their jurisdiction. Building departments review plans, issue permits, and conduct inspections to ensure compliance with the applicable building codes.

Building codes can vary from state to state and between jurisdictions, reflecting local geographic and climate conditions. For example, California's building codes focus more on earthquake resistance, while Florida's codes include more measures to address hurricanes and floods.

Building codes are updated by standards organisations and the International Code Council (ICC) when gaps or errors are identified

Building codes are a set of regulations that govern the design, construction, and modification of buildings and structures. They are intended to ensure the safety of occupants and the public by providing minimum standards for various aspects of construction, such as structural integrity, fire safety, and public health. Building codes are typically enforced by local authorities and vary from jurisdiction to jurisdiction.

In the United States, building codes are often based on model codes, which are developed by the non-profit International Code Council (ICC). The ICC was founded in 1994 through the merger of three regional model code organizations in the American construction industry. The organization develops and promotes the International Building Code (IBC) and various other model codes, standards, and resources. The IBC is designed to protect public health and safety while avoiding unnecessary costs and preferential treatment of specific construction methods or materials.

The ICC is not alone in its work. It is supported by several standards organisations, such as ASTM International, the National Fire Protection Association (NFPA), and the American Society of Civil Engineers (ASCE). These organisations develop and maintain standards that are referenced in the model codes produced by the ICC.

When gaps or errors are identified in existing building codes, or when new information about engineering, natural hazards, or human behaviour comes to light, standards organisations and the ICC can upgrade their standards and model codes. This process typically takes many years and involves the collaboration of various experts and stakeholders.

The process of updating building standards and model codes usually begins with the identification of a need for change. This need may arise from a building failure, a near-failure during a catastrophic event, or new insights into engineering, natural hazards, or human behaviour. Once the need for change is established, organisations such as the National Institute of Standards and Technology (NIST) step in to study and investigate the issue. NIST plays a crucial role in this process, utilising its legislative authority and technical expertise to get to the bottom of disasters and make informed recommendations for code updates.

After NIST and other organisations have conducted their investigations and studies, they collaborate with standards organisations and the ICC to turn their recommendations into actionable code updates. This collaboration ensures that the latest scientific and technical knowledge is incorporated into the building standards and model codes. The process of updating these codes typically involves committees, public hearings, and input from various experts and stakeholders. The goal is to create codes that are effective, safe, and feasible for implementation.

Once the updated model codes are finalised, they are presented to state and local lawmakers for adoption into law. Lawmakers may tailor the model codes to their specific needs, adding or removing requirements as necessary. This process of adoption varies from state to state and jurisdiction to jurisdiction, resulting in building codes that are customised to the specific needs and challenges of each area.

Building codes can increase construction prices, which in turn raises the cost of housing

Building codes are a set of regulations that govern the design, construction, and modification of structures in a particular jurisdiction. They are intended to ensure the safety, health, and welfare of the public by establishing minimum standards for construction. While building codes are important for public safety, they can also increase construction prices, which can have a knock-on effect on the cost of housing.

The impact of building codes on construction prices can be significant, especially when new or updated codes are introduced. For example, the 2012 International Energy Conservation Code (IECC) led to a 33% increase in construction costs for affordable rental housing in North Carolina. Similarly, the 2012 International Residential Code (IRC) changes resulted in cost increases ranging from $4,900 to $13,800 per home, primarily due to more stringent energy efficiency requirements. These increased costs can be passed on to consumers, making housing less affordable.

In addition to energy efficiency standards, building codes can also mandate specific materials or construction methods that may be more expensive. For instance, the International Wildland-Urban Interface Code, which aims to protect homes in wildfire-prone areas, can increase construction costs by up to $38,000 if vinyl siding is replaced with brick veneer. Fire sprinkler requirements can also add thousands of dollars to the cost of construction.

The impact of building codes on construction prices is particularly notable in the multifamily housing sector. The 2018 ICC code changes for multifamily buildings resulted in minimum cost increases of $2,500 to $25,000 per building. These increased costs can make it challenging for developers to build affordable housing and can lead to higher rents for tenants.

Furthermore, building codes can also increase the time and complexity of the construction process. The need to obtain permits, conduct plan reviews, and perform inspections can delay projects and increase costs. While these measures are important for ensuring compliance with safety standards, they can also add to the overall cost of construction.

While building codes are necessary to ensure the safety and welfare of the public, they can also contribute to rising construction and housing costs. It is important for policymakers and regulators to carefully consider the potential impact of building codes on construction prices and take steps to mitigate any negative effects, such as providing incentives for energy-efficient construction or streamlining the permitting process. By balancing the need for safety with the need for affordable housing, policymakers can help ensure that housing remains accessible to all.
