What's the Difference Between Rezoning, Platting, and a Conditional Use Permit?

These three terms get used almost interchangeably, but each one solves a different problem, and a given project might need one, two, or all three.
Rezoning changes a property's zoning classification. You need it when what you want to build isn't allowed under the site's current zoning at all, not even conditionally. It's a legislative decision, meaning the Planning Commission makes a recommendation and the City Council has to actually vote to approve it, usually after a public hearing. It's typically the most involved of the three, since the city has real discretion to say no.
Platting is the legal process of dividing land into distinct, recorded lots, or of dedicating easements and right-of-way. You need it when you're creating new buildable parcels, combining existing ones, or otherwise changing how a property is legally divided. It usually moves through a preliminary plat and then a final plat, and once approved, it gets recorded with the county so the new lot lines are official.
A conditional use permit, often called a CUP, doesn't change the zoning at all. It authorizes a specific use that a zoning district already allows, but only under certain conditions, things like limited hours, required screening, or a minimum amount of parking. You need one when your intended use is listed in the zoning code as conditional rather than permitted outright.
A single project can touch all three. A new subdivision might need a plat to create the lots, a rezoning if the intended use doesn't match current zoning, and a CUP if one of the buildings involves a conditionally allowed use. Knowing which of the three your project actually needs, ideally before you're under contract, is part of what a feasibility review is for.
