Stratification of assessment rollsReal property.

(1) Introduction. This rule explains the stratification process for real property. The stratification process is the grouping of real property within each county into homogeneous classifications based upon certain criteria in order to obtain representative samples. Stratification is used in determining the number of appraisals to be included in the ratio study and also for ratio calculation. The county's most current certified assessment rolls are used for stratification. Counties must stratify rolls using a land use code stratification system as prescribed by the department. (See RCW 36.21.100.)
(2) Stratification - Parcel count and total value - Exclusions. The stratification of the real property assessment rolls must include a parcel count and a total value of the taxable real property parcels in each stratum, excluding the following:
(a) Designated forest lands.(See chapter 84.33 RCW);
(b) Timberland classified under chapter 84.34 RCW. (See RCW 84.34.060);
(c) Current use properties in those counties where a separate study is conducted pursuant to WAC 458-53-095(3);
(d) State assessed properties; and
(e) State-owned game lands as defined in RCW 77.12.203(2).
(3) Stratification - By county. For the real property ratio study, the assessment roll must be stratified for individual counties according to land use categories and substratified by value classes as determined by the department. Stratification will be reviewed at least every other year by the department to determine if changes need to be made to improve sampling criteria. After the strata have been determined, the department will notify the counties of the strata limits, and each county must provide the department with the following, taken from the county's assessment rolls:
(a) A representative number of samples, as determined by the department, in each stratum, together with:
(i) The name and address of the taxpayer for each sample;
(ii) The land use code for each sample;
(iii) The previous year's assessed value for each sample;
(iv) The current year's assessed value for each sample; and
(v) The actual number of samples;
(b) The total number of real property parcels in each stratum; and
(c) The total assessed value in each stratum for both the previous year and the current year.
(4) Counties to provide information timely. The stratification information described in subsection (3) of this rule must be provided by the counties to the department in a timely manner to enable the department to certify the preliminary ratios in accordance with WAC 458-53-200(1). Failure to provide the information in a timely manner will result in the department using its best estimate of stratum values to calculate the real property ratio.
(5) Standard two-digit land use code. The following two-digit land use code will be used as the standard to identify the actual use of the land. Counties may elect to use a more detailed land use code system using additional digits, however, no county land use code system may use fewer than the standard two digits.

Real property sales studies.

(1) Sales study data. The basis of the real property ratio study is data obtained from real estate excise tax affidavits from each county. The department will supplement the sales study with appraisals when it is determined that the sales are insufficient to represent the level of assessment. The appraisals will be selected according to criteria set forth in WAC 458-53-130.
(2) Time period for data used. The sales study will only use sales occurring in the twelve-month period between May 1st preceding January of the current assessment year and April 30th of the current assessment year.
(3) Deduction from sale price. One percent will be deducted from the sale price shown on all valid real estate excise tax affidavits as an adjustment for values transferred that are not assessable as real property.
(4) Sales not included in the study - Assessment rolls using other than market value - New construction. Individual sales that show a sale price to assessed value ratio of under twenty-five percent, or over one hundred seventy-five percent shall be excluded from consideration in the study. However, if the number of individual sales meeting either one of these criteria exceeds five percent of the total number of valid sales for a county, then these sales shall be considered in the sales study.
(a) The exclusion of valid sales in accordance with this subsection shall not apply in situations where other than market value of a particular type of property is being listed on the assessment rolls of the county, as disclosed in any examination by the department. If other than market value is being listed on the assessment rolls for a particular type of real or personal property and, after notification by the department, is not corrected, the department shall adjust the ratio of that type of property, which adjustment shall be used in determining the county's indicated personal or real property ratio. When a particular type of property is found to be at other than market value, that type of property shall be separated from the other properties in the computation of the ratio. The department shall compile the total assessed value and total market value for that type of property, and it shall be included in the ratio as provided in WAC 458-53-135(3) and 458-53-160(3).
(b) The exclusion of valid sales in accordance with this subsection shall not apply to sales of property on which there is new construction value that has not yet been placed on the county assessment roll.

Real property appraisal studies.

(1) Review of prior year's sales. In order to determine which strata do not have sufficient sales to produce a sales sample representative of the level of assessment, the department shall review a county's prior year's sales studies. This review will determine the number of appraisals necessary to be added to the sales sample.
(2) Selection of properties for appraisal. The properties to be appraised by the department shall be selected on a statistically accepted random basis such as stated numerical sequence or random number tables.
(3) Department appraisals. Appraisals conducted by the department shall include a physical appraisal of the subject property in order to assure that the most accurate estimate of market value is determined, and shall not be conducted on the basis of mass appraisal techniques. The value determined will be the value as of January 1 of the assessment year, or for appraisals involving new construction, the value as of July 31.
(4) Review with county. The department shall review completed appraisals with the assessor and/or the assessor's staff. After the review is complete, the appraisals shall be included with the sales data for computation of the real property ratio.
(5) Allocation of real and personal property values. Allocation of value between real and personal property of the total value of appraised property for purposes of the ratio study will be determined using each assessor's method of classifying real and personal property.

Indicated real property ratio—Computation.

(1) Determination of ratio for assessed value strata. For each real property stratum, average assessed value and average market value shall be determined from the results of selected sales and appraisal studies. The average assessed value of the samples for each stratum divided by the average market value of the samples determines the ratio for each assessed value stratum.
(2) Determination of indicated market value. The actual total assessed value for each stratum divided by the ratio for each assessed value stratum, as determined by using the calculation set forth in subsection (1) of this section, determines the indicated market value of each stratum for the county.
(3) Addition of county assessed values for current use and forest land—Assessor's certification of values. The county assessed values of current use land and improvements (chapter 84.34 RCW) and forest land (chapter 84.33 RCW) as indicated on the current certification provided by the assessor to the county board of equalization are added to the actual total assessed value for the county. Ratios for current use land and improvements and for forest land are applied to the county assessed values to determine indicated market values.
(a) A copy of the assessor's certification to the board of equalization shall be filed with the department by July 15th, or when the rolls for the current assessment year are completed, whichever is later. The certification form shall be properly completed with all required information.
(b) If a copy of the assessor's certification is not received from an assessor prior to September 1, the assessor's abstract of assessed values for the current year may be used, when available. If not available, the assessed values from the abstract of the previous year may be used.
(4) Determination of county indicated ratio. The sum total of the county assessed values is divided by the sum of the indicated market values to determine the county indicated real property ratio.
(5) Example. The following illustration, using simulated values and ratios, indicates simplified ratio study computation procedures for real property.

(6) Department may consider general trends in property values. The department may consider the relationship between the market value trends of real property and the assessed value increases or decreases made by the assessor during the year in each county as checks of the validity of the results of the sales and appraisal studies. The assistant director of the property tax division of the department may authorize modification of the results of the sales and appraisal study in any county where there is a demonstrable showing by an assessor to the assistant director that the sales and appraisal study is inconclusive or does not result in a reasonable and factual determination of the relationship of assessed values to market value such that a significant variation results from the previous year not deemed by the assistant director to conform with general trends in property values.

Personal property ratio study.

(1) Introduction. This rule provides information about the personal property ratio study, including the basis for a county's personal property ratio, the determination of strata for each county, and the effect of the discovery of omitted property on the ratio study.
(2) Basis for personal property ratio. The basis for a county's personal property ratio will be valuation data with respect to personal property from the three years preceding the current assessment year.
(3) Stratification of rolls. Determination of strata for each county will be made by the department to ensure the selection of a representative audit sample and will be reviewed periodically. After the strata have been determined, the department will notify the counties of the strata limits and each county must provide the department with the following, taken from the county's assessment rolls:
(a) A representative number of samples, as determined by the department, in each stratum, together with:
(i) The name and address of the taxpayer for each sample;
(ii) The previous year's assessed value for each sample;
(iii) The current year's assessed value for each sample; and
(iv) The actual number of samples;
(b) The total number of personal property accounts in each stratum; and
(c) The total assessed value in each stratum for both the previous and the current years.
(4) Omitted property. If the department discovers omitted property in a county, the results of the department's audit will be included in the ratio study.

Indicated personal property ratioComputation.

(1) Determination of ratio for assessed value strata. For each personal property assessed value stratum, excluding properties identified in WAC 458-53-070 (4)(a), an average assessed value, and an average market value shall be determined from the results of selected audit studies. The average assessed value for each stratum divided by the average market value determines the ratio for each assessed value stratum.
(2) Determination of indicated market value. The actual total assessed value of the county for each stratum divided by the ratio for each assessed value stratum, as determined by using the calculation set forth in subsection (1) of this section, determines the indicated market value of each stratum for the county.
(3) Additional categories. The actual county total assessed values of properties identified in WAC 458-53-070 (4)(a) are added as a separate category to the total county assessed value. A ratio determined for these properties is applied against the total assessed value for the category to determine the indicated total market value for the category.
(4) Determination of county indicated ratio. The sum of the actual total county assessed values is divided by the sum of the indicated market values to determine the county indicated personal property ratio.
