Off-Grid Living in Dawson County, Nebraska

Dawson County, Nebraska is a bit of an outlier among rural Nebraska counties in that it actually has countywide zoning, adopted by the county board and administered by the Dawson County Planning Commission and a Zoning Administrator. That's important to know going in: some Nebraska counties leave land essentially unregulated, but Dawson County isn't one of them. If you're eyeing raw land here for an off-grid setup, expect the county's Planning & Zoning office to have a say in how you use it, and expect to pull permits for primary structures and accessory structures.

On dwellings, Nebraska state law (the manufactured-home statute) keeps counties from banning a manufactured home just because it's manufactured, as long as it carries the right HUD/modular seal. Dawson County can still require it meet the same foundation, hookup, setback, and size standards it applies to site-built homes. The county's own zoning definitions single out "Temporary Structures" separately from "Building," which hints that RVs and similar temporary units are treated differently than permanent dwellings, but I haven't confirmed specific size or occupancy rules for RVs at the county level, so ask the Zoning Administrator directly if that's your plan.

Building permits are handled at the county level through Dawson County Planning & Zoning, which reviews permits and enforces the zoning resolution. I could not confirm which edition of the IRC or IBC (if any) the county has formally adopted, so that's a call-and-ask item.

Septic and greywater are where the state steps in hard: Nebraska's NDEE, through its Onsite Wastewater Program (Title 124), governs onsite wastewater treatment systems statewide, and only certified professionals, PEs, or registered environmental health specialists can site, construct, or modify these systems. I found no Dawson County-specific septic ordinance or environmental health office, so this appears to run through the state process. Untreated greywater discharge isn't allowed; if you want to reuse it, it needs proper treatment and separate plumbing under that same Title 124 framework.

Rainwater harvesting has no state ban and I found no Dawson County ordinance addressing it either way, so I'm calling this unclear rather than assuming it's fully open.

Wells are a bigger local story: Dawson County sits inside the Central Platte Natural Resources District, which permits high-capacity wells and registers smaller ones, and which has active Groundwater Management Area rules that can restrict new irrigation wells and groundwater transfers in parts of the county. Well construction itself still has to meet state DHHS standards.

Bottom line for going off-grid disconnected from utilities: nothing forces you onto municipal power, water, or sewer here, but you still need to satisfy state septic and well rules plus Dawson County's zoning and building review for whatever structure you put up.
