<br /> <br />Crow Road Subdivision – City of Eugene <br />Type II Tentative Subdivision <br />June 2026 <br />Page 5 <br /> <br />5. Individual units of middle housing are permitted on middle <br />housing lots created pursuant to a middle housing land <br />division. <br />(b) Lot Area Reduction for Small Dwelling Units. When the average size <br />of all dwelling units in a duplex, triplex, fourplex, or cottage cluster <br />is less than 900 square feet as calculated using the formula in <br />subparagraph (c), the lot area thresholds listed in subparagraphs (a)1. <br />through (a)4. shall be reduced by 25 percent (for example, a triplex <br />with units of an average size that is less than 900 square feet would <br />be allowed on a lot with an area of 2,625 square feet). <br />(c) For the purposes of this subsection, “Average size” means the <br />average square footage of all dwelling units in a duplex, triplex, <br />fourplex, townhouse project, or cottage cluster using the formula: <br />AS = (X1+ X2 + X3 …+ X N) divided by N <br />Where: <br />AS = Average Size of all Dwelling Units in a Duplex, Triplex, <br />Fourplex, Townhouse Project, or Cottage Cluster <br />N = Total number of dwelling units in the duplex, triplex, <br />fourplex, townhouse project, or cottage cluster. N is equal to <br />the number of X# dwellings included within the parenthesis <br />in the calculation. <br />X# = Dwelling unit size. The size of one dwelling unit that is a <br />part of a duplex, triplex, fourplex, townhouse project, or <br />cottage cluster. Dwelling unit size is the total square footage <br />of a dwelling, which is measured by adding together the <br />square foot area of each full story or level in a dwelling. The <br />square foot area must be measured at the exterior perimeter <br />walls of each story of the dwelling, not including eaves, and <br />is defined as all square footage inside of a dwelling, <br />including, but not limited to, living rooms, kitchen, <br />bedrooms, bathrooms, hallways, entries, closets, utility <br />rooms, stairways, and bathrooms. For townhouses and <br />attached duplexes, triplexes, and fourplexes, the exterior <br />perimeter walls of a dwelling shall be measured from the <br />midpoint of any common wall for that portion of the <br />structure that shares a common wall with another unit in the <br />townhouse project, duplex, triplex, or fourplex. The <br />following are not included in the calculation of dwelling unit <br />size: attached or detached garages; outdoor living areas and <br />structures, including, but not limited to uncovered porches, <br />uncovered decks, patios, porches, exterior stairways, decks, <br />carports, and covered areas enclosed by no more than 50% <br />on all sides; and crawlspaces, attics, and other areas that do <br />not constitute a full story of the building. <br />(d) Lot Area Reduction for Income-Qualified Middle Housing. When at <br />least 50 percent of the dwelling units in a duplex, triplex, fourplex, or <br />cottage cluster meet the definition of income-qualified middle <br />housing, the lot area thresholds listed in subparagraphs (a)1. through <br />(a)4. shall be reduced by 25 percent. In calculating the number of <br />income-qualified middle housing units for purposes of this <br />subparagraph, fractional dwelling units shall be rounded down to the <br />nearest whole number (for example, 50 percent of the units in a <br />triplex equals 1.5 units, so at least 1 unit must be income-qualified for
