Properties in Clark County are appraised on an Annual Assessment cycle. Under Annual Assessment, the Department of Assessment and GIS reviews all parcels in the county each year to bring them to market value. Property owners are notified of any changes. State law requires that all property be valued at 100% of true and fair market value.

Industrial, commercial, and multi-family properties are evaluated and new values assigned.
Properties with new construction (including incomplete structures) and one-sixth of existing residential properties are physically inspected and valued.
The remaining five-sixth of residential properties are adjusted to market value based on sales information from the previous year.

Annual Assessment allows all property values to rise and fall with the market. This provides greater equity among property owners and a more stable tax base for those taxing districts that rely heavily on property tax to fund the services they provide.
