Yes. Regardless of county code status, septic/wastewater permitting applies through the health authority, wells and water rights run through the state, and floodplain rules follow federally connected financing. Minnesota state-level requirements are detailed on the county's full card.

What the Brown County card answers that this page doesn't:

How would you actually get water here? Well, rainwater, snowmelt, surface draw or hauling — which of those five are legal on Brown County land, and which one is genuinely your best path.
Can you grow enough to matter? The real length of the season, the thing that limits it, and whether preserving is optional or the whole plan.
What does it cost to own, every year? The effective property-tax rate and roughly what an acre runs.
What's most likely to wreck it? Every county has a leading hazard — wildfire, flood, sinkholes, drought. This county's is named on the card, along with what it means for building and for getting insured.
Sanitation without a sewer. Whether you can install your own septic, or whether the county forces a licensed installer.
Does more land actually buy you more freedom here? Usually not the way people assume. The card says plainly where the acreage thresholds bite and where they don't.
