(1,200)

1,200-square-foot minimum dwelling

(2) Minimum Square Footage Equivalents. Minimum square footage equivalents for dwellings shall be the finished area, not including garage or porches, as follows:

(a) For One-Story Dwellings. The gross area of the single above-ground level without vertical separation of more than 36 inches.

(b) For Two-Story Dwellings. The combined area of the two above-ground levels increased one and three-tenths times the area required for one-story dwellings. The floor area for a two-story dwelling shall be determined by taking the gross horizontal area covered on the ground plus the gross horizontal area of the total living space above the first floor, not including the portion over a garage.

(c) For Split-Level Dwellings. The same area required for one-story dwellings not including any portion below ground level. Minimum floor area of a split-level dwelling shall be determined by taking the gross horizontal living area of two adjoining floors above ground level.

(d) For Split-Entry Dwellings. The same area required for one-story dwellings not including any portions below ground level. Minimum floor area of a split-entry dwelling shall be determined by taking the gross horizontal area covered on the ground.

(3) No Minimum Dwelling Designation. Districts not provided with a minimum dwelling designation shall be regulated as (1,200) zones.

(4) Official Zoning Map Adopted. The official zone map is hereby adopted and made part of this title and zone districts shall exist and be established on the official zone map as adopted and amended from time to time.

(5) Rules for Locating Boundaries. Where uncertainty exists as to the boundary of any zone, the following rules shall apply:

(a) Wherever the district boundary is indicated as being approximately upon the centerline of a street, alley, block, or along a property line, then, unless otherwise indicated on the map, the centerline of such street, alley, or block of such property line shall be construed to be the boundary of such zone.

(b) Whenever such boundary line of such district is indicated as being approximately at the line of any river, irrigation canal or other waterway or railroad right-of-way, the boundary line of such public land or such section line shall be deemed to be the boundary of such zone.

(c) Where such district boundary lines cannot be determined by the rules in subsections (5)(a) and (b) of this section, their location may be found by the use of the scale appearing upon the map.

(d) Where the application of the rules in subsections (5)(a) through (c) of this section does not clarify the district boundary location, the board of adjustment shall interpret the map.

(6) Use Regulations. No building, structure or land shall be used and no building or structure shall be hereafter erected, structurally or substantially altered, or enlarged except as allowed in the districts as shown as permitted uses, indicated by a “P” in the appropriate column, or as conditional uses, indicated by a “C” in the appropriate column. If a regulation applies in the district it is indicated in the appropriate column by the letter “A” or by a numeral to show the linear or square feet or acres required. If a use is not allowed in the district or if a regulation does not apply, it is indicated in the appropriate column by a dash, “–.” Uses not listed are not allowed. The symbol “h” indicates the conditional use process must include a public hearing before the planning commission. [Amended during 2011 recodification. Code 1997 § 12-210.]
