Appraisers are physically inspecting Area 6 of Mason County. This area includes Harstine Island, Pickering and Grapeview Loops, Emerald, Spencer and Phillips Lakes, Timberlake’s, Agate and Shorecrest, and a portion of Highway 3 to the Deer Creek area. A physical inspection, required by RCW 84.41.041 , routinely includes an outside observation of the property in order to verify any changes, which could include the addition of new improvements and reviewing for signs of depreciation outside of the normal age of the property.

• The assessor’s office also relies upon the property owner for information. Taxpayers are encouraged to help by providing up-to-date and accurate property information whenever possible.
• Current physical inspections are a part of the 2023 assessment process, which will be for property taxes payable in 2024

Under the Department of Revenue guidelines, we work under a strict timeline schedule as to when we need to have our physical inspections completed, therefore we do not have time to make individual appointments, nor does the taxpayer need to be home during inspections as these are exterior inspections only. The appraiser will try to make contact upon arrival by knocking on the door of an improved parcel. In addition, we also encourage taxpayers that do have contact with our appraisers to discuss any ongoing issues with their homes or property in general, as the last time we physically inspected this area was six years ago. Also note that all appraisers will be wearing orange vests with their Mason County badge, and will be driving white Ford Escapes with the Mason County Assessor official logo on the side.

The County Assessor, or any employee designated by the assessor, does have the right to access your property in order to make an inspection for valuation purposes, pursuant to RCW 84.40.025.
