Appraisers are physically inspecting Area 1 of Mason County starting October 2023, which will be utilized for the 2024 assessment year/ 2025 tax year. This is a very large, unique area that includes Lake Limerick, Brockdale, McReavy, Hanks Lake, Eells Hill, California Rd, Highland Rd, Dayton Trails, Fawn Lake, Lynch Rd, Kamilche, Cloquallum Rd, Isabella Lake, Lost Lake, Lake Arrowhead, Star Lake, and Lake Nahwatzel out to Matlock.

In accordance with RCW 84.40.025, access to property is required for assessment and valuation purposes. Physical inspection means, at a minimum, an exterior observation of the property to determine whether there have been any changes in the physical characteristics that affect value. The property improvement record must be appropriately documented in accordance with the findings of the physical inspection.” (WAC 458-07-015)If access is refused, the appraiser must estimate the property value using available information, which may not result in an accurate assessment..

In accordance with the Department of Revenue's revaluation timeline and our volume of parcels, we do not make individual appointments, nor does the taxpayer need to be present at the time of inspection, as these are exterior inspections only. Upon arrival, the appraiser will attempt to make contact by knocking on the door of an improved parcel. State law mandates physical inspections at least once every six years (RCW 84.41.030); therefore, we highly encourage taxpayers to discuss any ongoing issues with their property to ensure our assessment represents the current condition. Please note, all appraisers will be wearing orange vests with a visible Mason County badge and driving a white Ford Escape with the Mason County logo.
