(a) For market value surveys with valuation dates on or after January 1, 1996, in order to determine the full value of assessing units which do not complete revaluation or update projects which are the basis of estimates of aggregate full value measurement as provided in section 8186-2.15 of this Subpart, the following apply.

1. (1) The measured roll is the assessment roll for the year immediately preceding the calendar year of the valuation date of the market value survey, except as provided in the procedures for the appropriate market value survey.
2. (2) The measured roll is collected by ORPTS and prepared for use as provided in the procedures for the appropriate market value survey.
3. (3) Property to be isolated from the measured roll is identified and removed.
4. (4) The measured roll is stratified into survey units, major types or classes, and intervals.

5. (5) Large units are identified.

   (c) Determination of sample parcels.

6. (1) The number of initial sample parcels for each interval is determined.
7. (2) There may be no initial sample parcels required in particular major types if the criteria regarding the size of the major type in the procedures for the market value survey are met.
8. (3) The required initial sample parcels are selected through a random selection process contained in the procedures for the appropriate market value survey. These procedures may provide for the substitution of alternative parcels for initial sample parcels.

9. (4) Sales may be used as provided in the procedures for the appropriate market value survey. These sales must meet the requirements in Subpart 8191-4 of this Title. These sales may either supplement, or substitute for, the initial sample parcel selections as provided in the procedures for the appropriate market value survey.

   (d) Determination of the full value.

10. (1) As provided in the procedures for the appropriate market value survey, sales may be substituted for initial sample parcels. Large units and the remaining initial sample parcels are appraised, and sales may be used to supplement these appraisals, as provided in the procedures for the appropriate market value survey. The appraisals reflect the condition of the parcel on taxable status date of the measured assessment roll and the value of the parcel as of the valuation date of the market value survey.
11. (2) The estimated full value is determined using the appraised values and sale prices, along with the corresponding assessed values of the properties from the measured assessment roll.
12. (3) Nothing herein prevents ORPTS from either including, or deleting, appraisals or sales from the data used to estimate the full value.

(b) Preparation and stratification of measured rolls.
