Building code/Regulations
building code, or building control, is a set of rules that specify the minimum acceptable level of safety for constructed objects such as buildings and nonbuilding structures. The main purpose of building codes are to protect public health, safety and general welfare as they relate to the construction and occupancy of buildings and structures. The building code becomes law of a particular jurisdiction when formally enacted by the appropriate authority.
Building codes are generally intended to be applied by architects and engineers although this is not the case in the UK where Building Control Surveyors act as verifiers both in the public and private sector (Approved Inspectors), but are also used for various purposes by safety inspectors,environmental scientists,real estate developers, contractors and subcontractors, manufacturers of building products and materials,insurance companies, facility managers,tenants, and others.
There are often additional codes or sections of the same building code that have more specific requirements that apply todwellingsand special construction objects such as canopies, signs,pedestrian walkways,parking lots, and radio and televisionantennas.
Types of building codes
The practice of developing, approving, and enforcing building codes varies considerably among nations. In some countries building codes are developed by the government agencies or quasi-governmentalstandards organizationsand then enforced across the country by thecentral government. Such codes are known as thenational building codes(in a sense they enjoy a mandatory nation-wide application).
In other countries, where the power of regulating construction and fire safety is vested in local authorities, a system of model building codesis used. Model building codes have no legal status unless adopted or adapted by an authority having jurisdiction. The developers of model codes urge public authorities to reference model codes in their laws, ordinances, regulations, and administrative orders. When referenced in any of these legal instruments, a particular model code becomes law. This practice is known asadoption by reference. When an adopting authority decides to delete, add, or revise any portions of the model code adopted, it is usually required by the model code developer to follow a formal adoption procedure in which those modifications can be documented for legal purposes.
There are instances when some local jurisdictions choose to develop their own building codes. At some point in time all major cities in the United States had their own building codes. However due to ever increasing complexity and cost of developing building regulations, virtually all municipalities in the country have chosen to adopt model codes instead. For example, in 2008 New York City abandoned its proprietary1968 New York City Building Codein favor of a customized version of the International Building Code.The City of Chicago remains the only municipality in America that continues to use a building code the city developed on its own as part of theMunicipal Code of Chicago.
Similarly, inIndia, each municipality and urban development authority has its own building code, which is mandatory for all construction within their jurisdiction. All these local building codes are variants of a National Building Code, which serves as model code proving guidelines for regulating building construction activity.
Scope
Building codes generally include:
  • Rules regarding parking and traffic impact
  • Fire coderules to ensure safe evacuation in the event of a fire
  • Requirements for earthquake,hurricane,tornado,flood, and tsunami resistance, especially in disaster prone areas or for very large buildings where a failure would be catastrophic
  • Drainage, green space, and fence-building rules
  • Requirements for specific building uses (for example, storage of flammable substances, or housing a large number of people)
  • Grandfathering provisions: Unless the building is being renovated, the building code usually does not apply to existing buildings.
  • Specifications on components
  • Allowable installation methodologies
  • Minimum and maximum room and exit sizes and location
  • Qualification of individuals or corporations doing the work
  • For high structures, anti-collision markers for the benefit of aircraft
Building codes are generally separate from zoning ordinances, but exterior restrictions (such as setbacks) may fall into either category.
Prescriptive vs. performance
These requirements are usually a combination of prescriptive requirements that spell out exactly how something is to be done, and performance requirements which just outline what the required level of performance is and leave it up to thedesignerhow this is achieved. Historically they are very reactive in that when a problem occurs the building codes change to ensure that the problem never happens again. In recent years there has been a move amongst most of the building codes to move to more performance requirements and less prescriptive requirements.

Traditionally building codes were generally short non complex interrelated sets of rules. They generally included reference to hundreds of other codes, standards and guidelines that specify the details of the component or system design, specify testing requirements for components, or outline good engineering practice. These detailed codes required a great deal of specialization to interpret, and also greatly constrained change and innovation in building design. In recent years several countries, beginning with Australia, have moved to much shorter objective based buildings codes. Rather than prescribing specific details, objective codes lists a series of objectives all buildings must meet while leaving open how these objectives will be met. When applying for a building permit the designers must demonstrate how they meet each objective.
