(a) 
The City of Willow Park defines, adopts, and establishes the following eleven (11) zoning “districts” in order to regulate and restrict the following: the location of trades and industries; the location of buildings erected, reconstructed, altered or enlarged for specific uses; the height and bulk of buildings hereafter erected, reconstructed, altered or enlarged; to determine the area of yards and other open spaces; and to limit the density of population. These eleven districts are broken into four classifications (hereafter referred to as “class”) which are referred to in the V.T.C.A. Local Government Code.

(b) 
The districts above and the boundaries of such districts are shown upon the city’s official zoning map and made a part of this chapter. The map and all the notations, references and other information shown thereon shall be as much a part of this chapter as if the matters and information set forth by said map were all fully described herein. If, because of error or omission in the official zoning map, any property in the City of Willow Park which is not shown as being in a specific district, and cannot be properly determined on any property in the city, such property shall be classified as “AG” Agricultural until changed by amendment. (Such classification by the city does not establish county agricultural tax status.)
(c) 
Except as specifically authorized to the contrary in this chapter the following regulations shall apply in all districts:
(1) 
No building permit, certificate of occupancy or other permit shall be issued, nor shall any use be made of land or any building or structure within the City of Willow Park unless a zoning district is specified for such land.
(2) 
No building or structure shall be erected, reconstructed, altered or enlarged; nor shall any building or structure or land be used for any purpose other than is permitted hereafter in the district in which such building, structure or land is located, and no building, structure or land shall be used and no certificate of occupancy, nor building permit shall be issued for any use or purpose prohibited by ordinance or by the constitution and laws of the United States of America or of the State of Texas.
(3) 
No building or structure shall be erected, reconstructed, altered or enlarged to exceed the height or bulk limit herein established for the district in which such building is located.
(4) 
No lot area shall be reduced or diminished so that the yards or other open spaces shall be smaller than prescribed by this chapter, nor shall the density of population be increased in any manner except in conformity with the area regulations herein established.
(5) 
No building permit shall be issued for any building or structure unless such building or structure is located on a platted lot or lots which have been described by an instrument recorded in the Parker County deed records in Texas, and the lot or lots front upon a legally established street. Notwithstanding the above, no building permit shall be issued for any building on and composed of a fractional part of any adjoining lot, or a lot and a fractional part of any adjoining lot, or the fractional parts of two adjoining lots.
(6) 
No yard or other open space provided about any building or structure for the purpose of complying with the provisions of these regulations shall be considered as providing a yard or open space for any other building or structure; provided further that no yard or open space on an adjoining property shall be considered as providing a yard or open space on a lot whereon a building is to be erected.
(d) 
Where uncertainty exists with respect to the boundaries of any of the aforesaid districts shown on the zoning map, the following rules shall apply:
(1) 
Where district boundaries are indicated as approximately following the centerlines of streets or highways, street lines or highway right-of-way lines, such centerlines, street lines, or highway right-of-way lines shall be construed to be said boundaries.
(2) 
Where district boundaries are so indicated that they approximately follow the lot lines, such lot lines shall be construed as said boundaries.
(3) 
Where district boundaries are indicated as approximately following a parallel to a drainage course or other prominent physical feature, that parallel line shall be construed to be said boundaries.
(4) 
Where district boundaries are so indicated that they are approximately parallel to the center of the streets, or the centerlines of the right-of-way lines of highways, such district boundaries shall be construed as being parallel thereto and at such distance therefrom as indicated on the zoning map. If no distance is given, such dimension shall be determined by the use of the scale of said zoning map.
(5) 
Where district boundaries are so indicated that they are approximately perpendicular to the centerline or right-of-way lines of streets, highways, or drainage courses, such district boundaries shall be construed to be perpendicular to said street, highways, or drainage courses.
(6) 
If the property is undivided, then the district boundary lines of the zoning map shall be determined by use of the scale appearing on the map.
(7) 
In the case of a district boundary line dividing a lot into two (2) parts the district boundary line shall be construed to be the lot line nearest the district boundary line as shown.
(8) 
Whenever any street, alley, or other public way is vacated by official action of the city council, the zoning district adjoining each side of such street, alley, or public way shall be automatically extended to the center of such vacation and all area included in the vacation shall then and henceforth be subject to all regulations of the extended district.
(9) 
Where the streets or alleys on the ground differ from the streets or alleys as shown on the zoning map, the streets or alleys on the ground shall control.
