I have not read the article yet myself but your comment is reasonable. We accidentally installed a non-compliant fence on our property (not in Texas) and I called the day after receiving the letter to find out our options since they had said we had X amount of weeks to remove it. The building inspector sighed and said, “listen, just the fact that you’re calling right now means that we’re not going to enforce that timeline”. It’s a boilerplate letter and as long as you’re taking action to remedy, they’ll work with you.
