Read this before you act on anything below. This is my researched starting point for Douglas County, NV, not legal advice and not a guarantee. Rules change, and the deciding facts on any specific parcel (setbacks, perc results, overlay districts, deed restrictions, road frontage) live at the county or town office, not in any database. Before you buy land or build, confirm the current rules directly with the local zoning and health offices - the sources on this page tell you exactly who to call.

The local rulesDouglas County, NV

Zoning & raw-land occupancy

Varies locallyCountywide zoning is set by the Douglas County Consolidated Development Code (Title 20) and Master Plan; what's allowed on raw land depends on the specific zoning district, per the Planning Division. source

Dwellings, tiny homes & RVs

Varies locallyTiny homes and ADUs are locally regulated under a state-mandated framework (NRS 278.253/SB 150); news reports describe a 2025 tiny-house ordinance requiring hard-plumbed/hard-wired utilities and barring RVs as permanent housing, but official ordinance text was not confirmed on the county site, so confirm with Planning. source

Building permits & codes

Generally allowedDouglas County adopts and enforces its own building codes (recently 2024 IBC/IRC/UPC/IMC family and 2023 NEC) under NRS 278.580; the Building Division issues permits and enforces the code. source

Septic & composting toilets

Generally allowedOn-site septic systems are permitted and inspected by Douglas County Community Development/Environmental Health consistent with state NAC 445A rules; composting toilets as a standalone full-time system are not confirmed as a permitted pathway, so verify with Environmental Health. source

Greywater reuse

Unclear - verifyNo Douglas County-specific greywater ordinance was found; it likely falls under the county's adopted Uniform Plumbing Code, but this is not confirmed, so ask the Building Division.

Rainwater harvesting

Generally allowedNo county-specific restriction was found; Nevada state law (AB 138) allows rooftop rainwater collection for non-potable use, and this appears to carry through at the county level by default.

Private wells & water rights

Varies locallyWell permitting and water rights in Nevada are a state function handled by the Nevada Division of Water Resources/State Engineer, not Douglas County; the county only requires permit applicants to locate existing wells before construction.

Living disconnected from utilities

Generally allowedNo county-level prohibition on living off-grid was found, but septic/OWTS permitting and the adopted building and plumbing codes still apply regardless of grid connection, per the county's building and septic materials. source
