Off-Grid Living in Humboldt County, Nevada

I've been digging into what off-grid living actually looks like in Humboldt County, Nevada, and the picture is fairly clear once you separate county rules from state rules. Here's what I found.

Zoning first. Humboldt County has countywide zoning, administered by the Planning and Zoning Department under authority granted by Nevada Revised Statutes 278.090. You can't just buy raw land and set up permanently wherever you want; what you're allowed to build or live in depends on the zoning district. The county's own FAQ is blunt about the grace period on undeveloped land: you can stay on a property for a total of 30 days without a well or sewage system, but after that you need a compliant well and septic system in place, or you have to move off.

Dwellings, RVs, tiny homes. This is the part people trip on. County code only allows an RV or "shelter" to count as a permanent, non-transient dwelling in the AG or M-3 zoning districts (or a licensed RV/mobile home park), and only once it meets IBC habitable-space standards and the plumbing code's water/sewer requirements. You need a county set-up permit from the Building Department before you move it in, and short-term occupancy is capped at 30 cumulative days before that permit is required. I found no separate "tiny home" code, so a tiny house on a foundation would likely fall under standard building permit rules, not a special exemption. Confirm your specific parcel's zoning with Planning before you buy or move anything onto it.

Building permits. The county has adopted IRC/UPC/UMC-style codes. Small accessory buildings under a modest size threshold (130 square feet, per the county) don't need a permit for the structure itself, but adding electrical, plumbing, or mechanical work to that building can still trigger permit requirements. Manufactured or modular homes need separate Nevada state approval.

Septic. Individual septic systems follow state standard NAC 444.8306, administered locally by the Building Department, and require percolation testing. Importantly, the county requires the well to be drilled before a septic permit is issued. Composting toilets aren't addressed anywhere I could find in county documents, so I'd treat a permitted septic system as the default requirement until the Building Department tells you otherwise.

Greywater and rainwater don't have Humboldt County, NV-specific rules that I could locate. Rainwater catchment appears fine under the state baseline. Greywater reuse likely falls under whatever plumbing code the county has adopted, so ask Building directly.

Wells. Domestic wells are approved by the state Division of Water Resources, not the county, and are exempt from the standard water-rights permitting process under NRS 534.080/534.180, capped at two acre-feet a year. The county will not accept hauled water as a substitute for a well. NDWR is also actively inspecting wells in this river basin for compliance with a specific state order, so expect scrutiny.

Utilities. Going off-grid on power isn't separately restricted, but the well/septic grace period above still applies, and reconnecting disconnected gas service requires a witnessed test and Building Department authorization.
