Off-Grid Living in Potter County, South Dakota

Potter County, South Dakota is one of those places where I have to be upfront about the limits of what's publicly findable. I went looking for Potter County's own zoning, building, and health department pages, and I could not locate an official one. That's not the same as saying "no rules exist," it just means I can't cite you a Potter County ordinance directly, and you'll need to confirm details by phone with the county.

Zoning. South Dakota counties don't have zoning automatically. They have to opt in under state law (SDCL Chapter 11-2), which lets a county commission adopt an ordinance covering land use, lot size, density, and structures. News coverage suggests Potter County's Planning Commission was still working through whether to adopt a countywide ordinance as of 2023, with parts of the county reportedly unzoned. I can't confirm the current status from an official source, so treat this as unclear until the county tells you otherwise.

Dwellings, tiny homes, RVs. No state law addresses this directly, it's left to individual counties. Since I can't confirm whether Potter County has adopted any zoning or building ordinance at all, I can't tell you whether a tiny home or RV-as-residence is fine, restricted, or simply unaddressed. Ask the county.

Building permits and codes. South Dakota has no mandatory statewide residential building code. When a local jurisdiction does adopt one, state law requires it comply with the 2021 International Building Code, but adoption itself is optional and up to each city or county. Many rural South Dakota counties skip building permits entirely outside town limits. Whether Potter County requires anything countywide is not confirmed.

Septic. This one has a real state backbone: DANR and the Water Management Board regulate on-site wastewater systems statewide, and installation has to be done by a state-certified installer. Permitting for a specific property is usually administered at the county level, similar to how Minnehaha County runs its septic permit program, but I couldn't find Potter County's own septic permitting page or office, so confirm the process locally.

Greywater and rainwater. Neither has a specific state statute or a confirmed Potter County rule. On water use generally, DANR exempts ordinary household or domestic use, drinking, washing, sanitary, and culinary needs by an individual or household, from needing a water right permit, which may be relevant to small-scale rainwater catchment, but there's no dedicated rainwater law on the books that I found.

Wells. This is the most solidly state-regulated area. DANR's Office of Water and Water Rights Program licenses well drillers, and ordinary domestic well use is exempt from a water right permit unless you exceed 25,920 gallons per day or a 25 gallon-per-minute peak pump rate. If you do need a permit, state law requires it be approved before you drill.

Off-grid utilities. No state law bans living disconnected from the grid. Electrical work is licensed statewide through the SD Electrical Commission, with an owner's exemption for wiring your own residence. No Potter County-specific rule on off-grid living turned up in my research.

Bottom line: start with the Potter County Auditor's office at the courthouse in Gettysburg to find out who currently handles zoning, building, and septic locally, because I could not verify that online.
