OAR 660-038-0040
Determine the Mix of Dwelling Units Needed
(1)
A city must determine the current mix of housing types within the city based on the percentages of low density, medium density, and high density residential dwellings using:(a)
For cities with UGB population less than 2,500, the percentages determined in the most recent five-year American Community Survey conducted by the United States Census;(b)
For cities with UGB population greater than or equal to 2,500, using either the percentages determined in:(A)
The most recent American Community Survey conducted by the United States Census, or(B)
An average of the two most recent American Community Surveys conducted by the United States Census.(2)
For the purposes of this rule and for OAR 660-038-0050 (Determine Amount of Land Needed for Each Housing Type):(a)
For cities with a UGB population less than 2,500, single-family detached dwellings shall be considered low density residential, and all other dwellings shall be considered medium density residential.(b)
For cities with a UGB population greater than or equal to 2,500, single-family detached dwellings shall be considered low density residential; single-family attached dwellings, mobile homes, and multiplexes with two to four units shall be considered medium density residential; and multi-family dwellings with five or more units shall be considered high density residential.(3)
A city must project the mix of housing types needed for new development over the 14-year period using the ranges of numbers in Table 1. The percentage of low density residential development is calculated by subtracting the percentage of medium density and high density residential development selected by the city from the table.(4)
To determine the number of low density, medium density and high density dwelling units needed over the 14-year period, the city must multiply the percentages of needed housing for different housing categories determined in section (3) by the total housing need determined in OAR 660-038-0030 (Residential Land Need).
