OAR 150-311-0240
Procedure to Correct MAV When Square Footage Error Exists


(1) For purposes of this rule, “Current RMV”, as used in subsection (4)(b), is defined as the RMV for the tax year of the petition. For example, a petition submitted in August 2016 will use the roll values for the 2016-2017 tax year to calculate the adjustment.
(2) To correct the maximum assessed value (MAV) of a property for an error in square footage, the assessor must receive a petition from either the current owner of the property or other person obligated to pay taxes imposed on the property. The petition must be filed with the county assessor on or before December 31 of the current tax year on a form prescribed by the department.
(3) The correction to MAV by the assessor must be in proportion to the correction to RMV due to the error in square footage.
(4) The proportion of error and resulting MAV are calculated as follows by the assessor:
(a) For properties described by a single component (for example, land only), use the following procedure to adjust MAV.
(b) For properties described by multiple components (for example, land and buildings, or more than one building or structure, or buildings and machinery), use either of the mathematically equivalent procedures in the short method or the long method in example B to adjust MAV.
(5) For a building that is valued by summing the individual value contributions from distinct portions of that building, the particular building portion affected by the square footage error may be considered as a separate component such as in example B above when making the correction to MAV. Examples of this type of building include but are not limited to a warehouse with attached offices or a house with an attached garage.
(6) Notwithstanding that a property’s MAV has been corrected due to a square footage error, the corrected MAV remains subject to adjustments required by ORS 308.146 (Determination of maximum assessed value and assessed value) to 308.166 (Ordering provisions when property is subject to multiple special determinations of value).
(7) Roll corrections pursuant to ORS 311.234 (Correction in maximum assessed value) are to be made using the procedures in 311.205 (Correcting errors or omissions in rolls).
