Plain-language change summary

The updated version of Bill HB 1308 has a few minor changes in its language and structure but retains the same core provisions. It specifies that starting December 31, 2027, certain jurisdictions can approve splitting a property into two lots, provided the smaller lot is at least 40% the size of the larger one. These adjustments were made to clarify the bill's intent and ensure it's easier to understand, which is important for property owners and developers who may need to navigate this process in the future.
