What is prohibited regarding the construction or demolition of a building?

The prohibition concerning the construction or demolition of a building fundamentally relates to compliance with applicable regulations and laws. The requirement to comply with the Act ensures that all building activities meet established safety, health, and environmental standards, which protect the public and the integrity of structures. Engaging in construction or demolition without adherence to these regulations can lead to unsafe conditions and legal repercussions.

The other choices present scenarios that are problematic but do not encapsulate the fundamental requirement for compliance with the overarching legal framework governing construction. While changing building plans after a permit has been issued might necessitate re-evaluation or approval, it doesn't outright prohibit construction; it simply involves processes to ensure ongoing compliance. Similarly, operating a sewage system without a permit is a specific violation but falls under a more particular regulatory category rather than the broad scope of construction or demolition activities. Issuing a building permit under any circumstances would be an impractical statement since permits are essential for legal construction and can only be validly issued if all other regulations are followed. Hence, the essence of the correct answer aligns with the crucial principle of ensuring that all construction and demolition activities adhere to the governing laws and standards.
