Washoe County adopted Chapter 5 of the 2024 IWUIC, effective 2025-07-01 — a narrower cut than a whole-book adoption, which shapes what applies to your house: the chapter, not the full code, is the operative text.

Six determinations stay with the county — boundary, map, hazard class, project scope, date, and sign-off — and what we can't tell you yet keeps that list visible rather than treating adoption as the end of the story.

Washoe is one of Nevada's 2 sourced local nodes, both carrying applications. It spans USDA half-zones 6b to 7b, with 337 plant records documented locally of 350 statewide; the planting side lives under living here.

What we can't tell you yet

Nevada has 2 sourced local nodes; 2 have a sourced construction application.

These checks stay open because the sourced instrument leaves them to the official record, not because this page skipped them:

Whether the instrument is in force for this project's date.
The official boundary that would put a parcel inside the application.
Confirmation from the building official for this project.
The official hazard class for the lot.
The official hazard or WUI map for the lot.
Whether this project type is in scope of the instrument.
