The correct choice focuses on the essential requirements for safe and compliant demolition in relation to plumbing. Securing a plumbing permit is crucial because it ensures that all plumbing systems are properly inspected and accounted for before demolition takes place. This permit verifies that any modifications to existing plumbing systems are completed in accordance with local codes, thereby protecting public health and safety.

Additionally, ensuring all connections are gas and water tight is vital to prevent leaks or hazardous situations during the demolition process. These precautions help avoid potential environmental impacts or safety hazards related to escaped gas or water infiltration, which could pose risks both during and after the demolition.

The other options, while they mention relevant actions, do not directly address the key plumbing-related requirements necessary when demolishing a building. For instance, obtaining a demolition permit and disconnecting electrical wiring relates to broader demolition safety and compliance but does not specifically pertain to plumbing. Notifying the local fire department and removing window panes may be considered safety measures, but they do not reflect plumbing concerns. Lastly, installing new plumbing fixtures and repainting walls do not apply in the context of a demolition scenario, as these actions would typically take place after demolition rather than during.
