Off-Grid Living in Lyon County, Nevada

I've been digging into Lyon County, Nevada for folks who want to live off-grid or close to it, and the short version is: there's no single "off-grid ordinance" here. What you're dealing with is a patchwork of Lyon County's Title 15 Land Use and Development Code, the county Building Department's policies, and referrals out to state agencies like NDEP and the Nevada Division of Water Resources. Let me walk through what I found.

Zoning. Unlike some rural Nevada counties, Lyon County does have countywide zoning under Title 15, adopted in 2018. It's built around the county's seven unincorporated communities and is meant to let people "grow in place" while preserving community character. That means raw-land occupancy isn't a free-for-all, whatever you want to do has to fit the zoning district you're in, so check with Lyon County Planning before you buy or camp long-term.

Dwellings, tiny homes, RVs. Nevada's SB 150 lets counties under 100,000 people (Lyon qualifies) designate districts where tiny houses can be an accessory dwelling, a single-family residence, or part of a tiny house park, built to Appendix Q of the IRC. Manufactured homes face stricter rules: Lyon County requires a minimum size and more than one section, plus a full poured-in-place foundation engineered for local conditions. RVs generally aren't allowed as permanent housing. Watchman's quarters or hardship mobile homes need an administrative variance.

Building permits. The Lyon County Building Department enforces codes adopted by the Board of Commissioners. Structures under a certain small size may skip a building permit, but the moment you add electrical, plumbing, or mechanical systems, permits kick in for those trades regardless of the structure's size. Nevada law allows owner-builder permits with a signed affidavit.

Septic and composting toilets. This one's genuinely fuzzy. Septic permits are referenced as a county category, but Lyon County leans on the state's NDEP (under NAC 445A) for the actual standards, and I couldn't confirm a dedicated county composting-toilet policy. Ask the county's Environmental Protection office or NDEP directly.

Greywater and rainwater. I found no Lyon County-specific rule on greywater reuse, so it likely falls under whatever plumbing code the county has adopted, confirm with Building. Rainwater harvesting follows Nevada's statewide allowance under AB 138, with no added county restriction found.

Wells and water rights. Wells are state-administered through the Division of Water Resources, and Lyon County's building process requires proof that water rights are properly handled before you can build on a well-served lot. If you're in Mason or Smith Valley, the Walker River Irrigation District also has to approve your site plan.

Disconnecting from utilities. You can live off electric grid power without an obvious county objection, but the building permit process still requires water and sewer service to be located on the same parcel as the home, meaning a compliant well and septic system, even if you're off the power grid.

Bottom line: Lyon County allows a lot of off-grid-style living, but almost everything routes through a permit somewhere, county or state.
