The Building Act 1984 is a key piece of legislation in the United Kingdom that governs building regulations and standards. It aims to ensure the safety, health, and welfare of people in and around buildings. The Act provides a framework for the construction and alteration of buildings, setting out requirements for structural integrity, fire safety, and accessibility. Under the Act, local authorities are responsible for enforcing building regulations, which include obtaining necessary approvals before construction begins. The Act also allows for the establishment of codes of practice and standards, ensuring that buildings are safe and suitable for their intended use, thereby protecting the interests of the public and the environment.
