An ordinance amending Chapters 17.04, 17.12 and 17.16 of the Metropolitan Code pertaining to two-family dwellings (Proposal No. 2014Z-009TX-001).


Section 1. Title 17.04.060 (Definitions of general terms) is hereby amended by deleting the definition of “Two-Family” in its entirety and replacing with the following:
1. Two attached dwelling units that share the floor of a unit with the ceiling of another unit or a common wall from grade to eave at the front façade which continues for eighty percent (80%) of the common side or 20 feet, whichever is greater; or
2. Two detached dwelling units on a single lot which are separated by at least six feet.
3. In historic zoning overlays, the manner or existence of attachment shall be determined by the Metro Historic Zoning Commission.

Section 2. Table 17.12.020A is hereby amended by inserting the following as Note 4:
In addition to the height restrictions in 17.12.060, the height of two detached dwelling units on a single lot cannot exceed a ratio of 1.0 horizontal to 1.5 vertical for each structure. Maximum height shall be measured from the natural grade. The natural grade shall be determined based on the average elevation of most exterior corners of the front facade, to the roof line. Natural grade is the base ground elevation prior to grading. The appropriate height shall be determined by the Metro Historic Zoning Commission for properties within a historic overlay. Notwithstanding the above provisions, two-family structures legally constructed prior to the effective date of this ordinance may remove the connector required under the previous definition of two-family, regardless of the height of the units.

Section 3. Title 17.16.030.D is hereby amended by deleting the following phrase:

“in a single residential structure”

Section 4. Be it further enacted, that this ordinance take effect immediately after its passage and such change be published in a newspaper of general circulation, the welfare of The Metropolitan Government of Nashville and Davidson County requiring it.
