<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
