Final answer:
The penalties for a second-time violation by an unlicensed residential contractor under Act 299 cannot be determined from the given information, so consultation of the actual act or legal advice is necessary.
Step-by-step explanation:
The question is asking about the penalties for a second-time violation by an unlicensed residential contractor under Act 299. While the information provided does reference penalties for carrying weapons on public recreational property, it does not specifically address the sanctions for unlicensed contracting violations.
In absence of the exact data for contracting penalties, the answer cannot be confidently determined and is therefore not provided. To find the specific penalty for the second violation of Act 299 by an unlicensed residential contractor, it is advisable to consult the latest version of the act itself or seek legal advice.
The penalties for law violations can vary and are subject to change based on legislation updates.
