What must a permit for a home improvement include according to Section 8-504?

A permit for a home improvement project must include the license number of a licensed contractor to ensure that the contractor is legally authorized to perform the work in question. This requirement helps to maintain a standard of professionalism and accountability within the industry. By having the contractor's license number, regulatory bodies can verify the contractor's qualifications, ensuring that they meet the necessary standards and regulations established for home improvement work in Maryland. This not only protects the homeowner from potential fraud but also ensures that the work done on their home adheres to safety and quality standards mandated by law. The other options do not serve this purpose and are not relevant to the requirements outlined in Section 8-504.
