[Added 1-3-2006 by Ord. No. 2430]
A masonry coverage requirement shall apply in the R-1, R-2, R-3, R-4, R-5, R-6 and R-7 Districts as follows.
For real estate subdivisions the final subdivision plats for which are approved by the City's City Council after the third day of January, 2006, the exterior walls of single-family dwelling houses constructed in these zoned districts shall be constructed in compliance with the following exterior building materials requirement:
A. 
A minimum of three sides (profiles) of the exterior walls of 50% of the dwelling houses to be located on the lots in the subdivision shall be constructed of face brick, from the ground level (the building foundation) to the building's eaves [excluding gables, dormers, openings for windows and doors, trim and for accenting authorized by the City's City Council (after considering the recommendation of the City's Building Official and/or the Plan Commission)].
[Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. I)]
B. 
The front facade (the profile of the dwelling house facing the street) of 30% of the dwelling houses to be located on the lots in the subdivision shall be constructed of face brick, from the ground level (the building foundation) to the building's eaves [excluding gables, dormers, openings for windows and doors, trim and for accenting authorized by the City's City Council (after considering the recommendation of the City's Building Official and/or the City's Plan Commission)].
[Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. I)]
C. 
The exterior walls of 20% of the dwelling houses to be constructed on lots located in the subdivision may be constructed of building materials other than face brick, which may include but shall not be required to be limited to stucco, vinyl siding, wood siding, or cement board lap siding.
A. 
Notwithstanding the exterior wall masonry building coverage requirement contained in § 300-9.2 above, when by reason of exceptional topographical conditions or other extraordinary or exceptional situation or condition of a specific piece of property, which condition is not generally prevalent in the area, the strict application of the requirements contained in § 300-9.2 above would result in peculiar and exceptional practical difficulties or exceptional and undue hardship upon the owner of such property, the City Council shall be empowered to authorize, upon application in regard to such property, a variance from such requirements to allow the dwelling house to be constructed on the property to be constructed of materials other than those required by § 300-9.2, provided:
(1) 
The proposed materials are authorized and approved by the Columbia Building Codes in effect at the time of reference; and
[Amended 4-6-2009 by Ord. No. 2714]
(2) 
The proposed materials are authorized by the City Council (with the advice and/or recommendation of the City's Zoning Administrator and/or the Plan Commission).
[Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. I)]
B. 
In granting a variance to a property owner pursuant to Subsection A, economic hardship caused to a property owner resulting from the cost of exterior building wall brick masonry construction as compared to the cost of alternative exterior building wall building material construction authorized and approved by the Columbia Building Codes shall not be a factor to be considered by the City Council. Such economic hardship caused to a particular property owner shall not constitute a peculiar and exceptional practical difficulty or exceptional and undue hardship upon the property owner justifying relief from the strict application of the requirements of § 300-9.2 above.
[Amended 4-6-2009 by Ord. No. 2714]
A. 
Each preliminary subdivision plat and final subdivision plat (including plats for subdivisions to be platted and developed in phases or additions) submitted to the City for City Council approval shall depict on the plat drawing and shall state in a note or chart on the plat which lots shall be restricted to a minimum of three sides (profiles) exterior brick masonry walls, which lots shall be restricted to a minimum of a front facade wall (profile) exterior masonry brick requirement and which lots shall be unrestricted as to an exterior wall brick masonry requirement. For ease of reference, the following code (or abbreviations) may be depicted on the lots on the plat drawing and used on the chart with reference to the subject restrictions:
(1) 
For three sides brick: (B3).
(2) 
For front facade brick: (BF).
(3) 
For unrestricted lots: (0).
B. 
Plat submittals which lack the number of building lots to fully satisfy the exterior wall masonry brick restriction percentages required by § 300-9.2 above shall be required to favor the more restrictive over the less restrictive or unrestricted building lot exterior wall brick masonry requirement; so that, for example:
(1) 
If there are only three building lots in a subdivision, two of the building lots shall be subject to the three sides brick wall (B3) restriction and the remaining one building lot shall be subject to the front wall brick facade (BF) restriction;
(2) 
If there are only five building lots in a subdivision, three of the building lots shall be subject to the three sides brick wall (B3) restriction and the remaining two building lots shall be subject to the front facade brick wall (BF) restriction; and
(3) 
If there are only six building lots in a subdivision, three of the building lots shall be subject to the three sides brick wall (B3) restriction, two of the building lots shall be subject to the front facade brick wall (BF) restriction and the remaining one building lot will not be subject to an exterior wall brick masonry construction restriction.
C. 
The application of the exterior wall brick masonry requirement percentages required by Subsection B(1) above shall be determined by the number of lots in a subdivision and not by the square footage of the bulk area of a subdivision or by some other method of measurement. The subdivider shall be required to select the location of the restricted and the unrestricted lots, in accordance with the requirements of Subsection B(1) above, at the time of the subdivider's first subdivision plat submittal to the City (that is, at the time of preliminary plat submittal for other than minor subdivisions and at the time of final plat submittal for minor subdivisions).
D. 
The exterior wall brick masonry requirement restriction that attaches to each building lot in a subdivision shall be a minimum construction requirement; shall run with the land to which the restriction pertains; and a restricted lot may not be exchanged for an unrestricted lot or less restricted lot in the subdivision (and thereby be relieved of its exterior wall building material restriction), except by a replatting of the subdivision approved by the City's City Council.
As used in this article, the following terms shall have the meanings indicated:
BRICK
Natural clay-face brick, and does not include glazed brick or concrete brick unless otherwise indicated or the context clearly requires otherwise.
STONE
Stone masonry composed of field, quarried or cast stone units bonded by mortar unless otherwise indicated or the context clearly requires otherwise.
This article shall be in full force and effect from and after its passage and approval, as provided by law, as follows:
A. 
As to subdivisions for which a preliminary subdivision plat has been approved by the City Council prior to the date of the enactment of this article, but a final subdivision plat for that subdivision has not been filed with the City Clerk prior to the enactment of this article, the final subdivision plat for that subdivision shall be required to comply with the requirements of this article, but an amended preliminary plat shall not be required notwithstanding the requirement of the City's Subdivision Code that a final subdivision plat must comply with the approved preliminary plat for the subdivision (from which Subdivision Code compliance requirement a variance is hereby granted).
B. 
As to subdivisions for which a preliminary subdivision plat has been filed with the City Clerk prior to the enactment of this article, but the preliminary plat has not been approved by the City Council prior to the enactment of this article, the preliminary plat and the final plat for that subdivision shall be required to comply with the requirements of this article.
C. 
As to subdivisions for which the final subdivision plat has been filed with the City Clerk but has not been approved by the City Council prior to the enactment of this article, the final plat for that subdivision shall not be required to comply with the requirements of this article.
D. 
As to subdivisions for which neither a preliminary subdivision plat nor a final subdivision plat has been filed with the City Clerk prior to the enactment of this article, the preliminary plat and the final plat for that subdivision shall be required to comply with the requirements of this article.
