Introduction:
Byelaws are rules and regulations set by local authorities to control the development and use of land and buildings within their jurisdiction. They serve various objectives to ensure the orderly development and safety of the built environment.

Objective of Byelaws:
Byelaws have several objectives, which can be broadly categorized into the following:

1. Preplanning and Design Guidelines:
One of the objectives of byelaws is to ease the preplanning of buildings and provide guidelines to the designing architect. Byelaws specify the permissible land use, setbacks, building height, floor area ratio, and other parameters that architects and builders need to consider during the design process. These guidelines help in achieving a harmonious and aesthetically pleasing built environment.

2. Prevention of Hazard Development:
Byelaws aim to prevent the development of hazardous buildings and structures. They establish standards and regulations for structural stability, fire safety, electrical installations, and other aspects that can pose risks to the occupants and the surrounding areas. Byelaws ensure that buildings are constructed and maintained in a safe and secure manner.

3. Safety of Occupants:
Byelaws prioritize the safety of occupants by providing provisions for fire safety, noise control, health hazards, and structural failure. They mandate the inclusion of fire safety measures such as fire exits, fire-resistant materials, and fire alarms in buildings. Byelaws also address noise pollution by setting limits on permissible noise levels and specifying noise insulation requirements. Additionally, they address health hazards by regulating sanitation facilities and waste disposal systems in buildings. Byelaws also ensure that buildings are constructed to withstand structural failures, such as collapse or damage due to earthquakes or other natural disasters.

4. Affordable Housing:
It is important to note that providing affordable housing to everyone is not typically an objective of byelaws. While some byelaws may include provisions related to affordable housing, it is not a primary objective. Affordable housing initiatives are usually addressed through separate policies, incentives, and regulations implemented by the government or local authorities.

Conclusion:
In conclusion, the correct answer is option 'B' - providing affordable housing to everyone is not an objective of byelaws. Byelaws primarily focus on easing preplanning, preventing hazard development, ensuring the safety of occupants, and maintaining a harmonious built environment. Affordable housing initiatives are usually addressed through separate policies and regulations.
