On any legal matters, you should consult with your real estate attorney. There are a few questions that need to be answered to give you an accurate and complete answer. Are you currently under contract to purchase this home? Was the fence broken when you went into contract? Did you mention the broken fence in the contract? Does the owner already have a CO for the pool and you want them to come up to the current codes? The answers to these questions will greatly determine the answer to your question. Good luck.
