Who told you that? It is certainly not state law. Subdivision is simply dividing a large parcel of land into plats which can be zoned for various uses. You can have a industrial subdivision. The only requirement I am aware of for residential subdivisions is hookup to water and sewer unless the parcels are over a certain size.
You are probably thinking of the fact that many new subdivisions are built under a developer’s control who then turns over that control to an HOA. There are laws regarding such a transfer. But HOA are not mandatory for new subdivisions.
I should have written the only statutory requirement I am aware of for subdivisions developed after 1971 (may be wrong on the year) is that they be hooked up to water and sewer unless the lots are over a certain size.
