National Building code is a document containing standardized requirement for the design & construction of most types of apartments in India. Although codes may sometimes seem fussy, they are the result of years of experience and testing. Building codes exist to protect the public’s health, safety and welfare. National Building Codes (NBC) regulate building construction & building use in order to protect the health, safety & welfare of the occupant. You must always take the correct precautionary measures to assure the safety of your family members.
National Building code is a document containing standardized requirement for the design & construction of most types of building in the country. The Code was first published in 1970 at the instance of the Planning Commission and then revised in 1983. Thereafter three major amendments were issued, two in 1987 and the third in 1997. These amendments were made considering a series of further developments in the field of building construction including the lessons learnt in the aftermath of number of a natural calamities. As a culmination of the Project, the revised NBC has now been brought out as National Building Code of India 2005 (NBC 2005). The NBC 2005, formulated by the Bureau of Indian Standards, spells out new regulations for adoption by infrastructure departments, municipal administrators, public bodies and private agencies. It contains mainly administrative regulations, development control rules and general building requirements, fire safety requirements, stipulations on use of materials, structural design and construction and building and construction, building and plumbing services.
The National Building Code (NBC) is now a national instrument that will guide the regulations for construction activity. It contains all the important aspects relevant for the safe and orderly building development. The building that does not satisfy building code or violates the National building code will lead to penalty, cancellation of sanction or demolition of the building.
Lift shall be provided in all buildings: In case of a building having a height more than 13 meters, a lift shall be provided.

Plumbing Services: A plumbing or sanitation code is a set of rules and regulations imposed by cities or counties. Anyone doing work on drinking water and sewer or toilet facilities systems are responsible to make the work in a specific and safe manner to avoid accidents and the spread of diseases. Water conservation and the health aspects of plumbing have become important in the construction sector now. The National Building Code offers only guidelines for construction. Plumbing has to be attuned to the general design of the building. Many technical aspects such as water pressure, venting and concepts of wet and dry areas in toilets have to be looked into in any structure. Recently, the International Association of Plumbing and Mechanical Officials (IAPMO) developed a Plumbing Code for India. The Indian Plumbing Association (IPA), the country’s apex body of plumbing professionals, has launched ‘Uniform Plumbing Code’ (UPC).The World Plumbing Council’s uniform plumbing code was mended as per Indian needs and created the code for India.
Lightning Protection: Locations, surrounded partially or fully by unbroken metallic surfaces or nets do not allow lightning to penetrate to the interior and hence a person is safe inside. Lightning prefers to strike the tallest of all objects in a location. Also, it prefers metal objects. The larger the metal, the more is the chance of lightning striking it. Avoid using metallic pipes to fix lamps on the terrace of buildings. Also for drying clothes on the terrace, iron poles with metallic or plastic wires are used. TheLightning Conductor which is also known as Lightning Rod or Air Terminal is one of the best known forms of shielding device and has been in use in protecting buildings and facilities where protection is mandatory. The protective value of Inside buildings is better when at least some unbroken vertical metallic conductors exist, such as rain gutters with down-pipes, water mains, rails for elevators, vertical metal strips, steel braces or reinforcement, electrical installations and wires, etc. Electrical and electronic equipments can be protected to a considerable extent from damage by installing a Lightning Arrestor.
