What information is required for a plumbing permit application in Massachusetts?

The correct choice highlights the comprehensive information required for a plumbing permit application in Massachusetts. When submitting a plumbing permit application, it is essential to provide detailed plans and specifications to ensure that the proposed work complies with existing regulations and codes. This includes a clear description of the work to be performed, which helps the reviewing authorities understand the scope and nature of the project.

Additionally, including licensed contractor information is crucial as it verifies that the individual or company performing the work is certified and compliant with state regulations. This ensures accountability and adherence to safety and quality standards throughout the plumbing installation or repair process.

The other options are insufficient as they lack the necessary depth of information required by the Massachusetts plumbing code. Simply providing a contractor's name, a verbal agreement, or just the location does not fulfill the regulatory requirements for a plumbing permit application.
