[Ord. No. 646 §2]
The boundaries of the zoning districts are indicated upon the zoning district map of the city, which map is made a part of this chapter. The zoning district map of the city, and all the notations, references and other matters shown thereon, shall be as much a part of this chapter as if the notations, references and other matters set forth by the map were all fully described herein; such zoning district map is attested and is on file in the office of the city clerk.
[Ord. No. 646 §2]
All territory which may be annexed to the city shall automatically be classed as having the same land use, area, height, yard and intensity of use regulations as authorized by the St. Louis County zoning Ordinance in effect at the time the area is unincorporated until such classification shall have been changed by an amendment to this chapter, as provided by law.
[Ord. No. 646 §2]
All areas within the boundaries of the city which are under water and not shown as included within any district shall be subject to all of the regulations of the district which immediately adjoins the water area. If the water area adjoins two or more districts the boundaries of each district shall be construed to extend into the water area in a straight line until they meet the other district.
[Ord. No. 646 §2]
Whenever any street, alley or other public way is vacated by official action of the board of aldermen or other public officials, the zoning districts 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 districts.
[Ord. No. 646 §2; Ord. No. 803 §1; Ord. No. 1633 §3, 9-17-2002; Ord. No. 1813 §1, 1-4-2005; Ord. No. 1978 §1, 6-19-2007]
Except as herein provided:
(a) 
No building shall be erected, converted, enlarged, reconstructed or structurally altered, nor shall any building or land be used for any purpose other than is permitted in the district in which such building or land is located.
(b) 
No building shall be erected, converted, enlarged, reconstructed or structurally altered to exceed the height limit established for the district in which such building is located.
(c) 
No building shall be erected, converted, enlarged, reconstructed or structurally altered except in conformity with the area regulations of the district in which such building is located.
(d) 
The minimum yards and open spaces, including lot area per family requirement, for each and every building existing on March 16, 1982, shall not be encroached upon or considered as yard or open space requirement for any other building.
(e) 
Every building hereafter erected or structurally altered shall be located on a lot, and in no case shall there be more than one main building on one lot, except as provided in section 23-167.
(f) 
No land dedicated for roadway purposes, either in a public or a private street or place shall be used as a yard or as any part of the required lot area prescribed by this chapter.
(g) 
Off-street parking spaces shall be provided and maintained in accordance with the requirements of this chapter.
(h) 
The exceptions listed below in subsection (i) to the restrictions stated in subsections (a) and (c) of this Section may be permitted by the Board of Aldermen only when an application for one (1) of the listed exceptions has been filed according to the procedures stated in section 23-182.
[Ord. No. 2723, 6-20-2023]
(i) 
Possible exceptions to the restrictions stated in subsection (a) of this section are the following:
(1) 
Permitted uses for "C" Districts listed in Section 23-90 may be considered for location in "M-1" Districts and "M-2" Districts described in Article XI and Article XII of Chapter 23, respectively, but means of the special use permit process;
(2) 
Permitted uses for "M-1" Districts listed in Section 23-110 may be considered for location in "M-2" Districts described in Article XII of Chapter 23.
[Ord. No. 646 §2]
Where uncertainty exists with respect to the boundaries of the various districts as shown on the zoning district map made a part of this chapter, the following rules shall apply:
(a) 
The district boundaries are the right-of-way center lines of either streets or alleys unless otherwise shown; and where the district designated on the map is bounded approximately by street or alley lines, the street or alley right-of-way center line shall be construed to be the boundary of such district.
(b) 
In the event that a zoning district boundary line is shown on a zoning district map as following a property line or a political boundary line, the actual location of such zoning district boundary line shall govern, as determined by survey, rather than the representation of the location of such boundary line on the district map, if there is a discrepancy between the two locations.
(c) 
Where the district boundaries are not otherwise indicated and where the property has been or may hereafter be divided into blocks and lots, the district boundaries shall be construed to be the lot lines; and where the districts designated on the zoning district map are bounded approximately by lot lines, the lot lines shall be construed to be the boundary of such district unless the boundaries are otherwise indicated on the map.
(d) 
In unsubdivided property, the district boundary lines on the zoning district map shall be determined by use of the scale appearing on the map.
(e) 
In interpreting and applying the provisions of this chapter, they shall be held to be the minimum requirements for the promotion of the public safety, health, convenience, comfort, prosperity or general welfare. It is not intended by this chapter to interfere with or abrogate or annul any easements, covenants or other agreements between parties; provided, that where this chapter imposes a greater restriction upon the use of buildings or premises or upon height of buildings, or requires larger open spaces than are imposed or required by other ordinances, rules, regulations or by easements, covenants or agreements, the provisions of this chapter shall govern.
