Washoe County, NV Landscaping Rules: Weed Ordinances (2026)

Washoe County has no separate municipal weed ordinance in Chapter 50 beyond the general nuisance list; the operative law is Chapter 555 of the Nevada Revised Statutes, Control of Insects, Pests and Noxious Weeds. 150 puts the duty to control state-designated noxious weeds on every landowner, occupant, railroad, canal or ditch company, and on every county, city or district that controls streets, alleys or rights-of-way, whenever the State Quarantine Officer requires it. 160, serves written notice on the landowner describing the weeds and the deadline and method for controlling them; one such notice is enough for the whole growing season.

170 lets the Quarantine Officer notify the Washoe County Board of County Commissioners, which must then control the weeds itself using county funds and bill the property. 180, the county treasurer mails the owner an itemized cost statement, and the owner has 30 days to object and get a hearing before the board; if no objection is filed, the cost is entered on the tax roll and becomes a lien on the land, collected the same way as other property tax liens. 201 makes it a civil offense to violate the control requirements or ignore the Quarantine Officer's conditions, with penalties of $250 for a first violation, $500 for a second, and up to $1,000 for each violation after that. 130, so ordinary lawn grass or non-listed weeds fall outside this particular statute's reach.
