(Ordinance 2019-13 adopted 4/9/19)
[1]
Editor's Note: Said schedule is included as an attachment to this chapter.
(a) 
Where the frontage on one side of the street between two intersecting streets is divided by two or more zoning districts, the front yard shall comply with the requirements of the most restrictive district for the entire frontage from one intersecting street to the other.
Front Yard Where Zoning Changes in a Block
(b) 
A mobile or HUD-manufactured home as a fixed dwelling shall observe the front yard specified for the district in which the dwelling is located. A mobile or HUD-manufactured home as a transient dwelling shall observe a minimum front yard of fifteen (15) feet from a public street and three (3) feet from a private drive.
(c) 
Where a building line has been established by plat or ordinance and such line requires a front yard setback greater or lesser in depth than is prescribed by this ordinance for the district in which the building line is located, the required front yard shall comply with the minimum required front yard as established by section 14-7-5. All residential development located on a cul-de-sac shall have a minimum front yard building setback of fifteen (15) feet.
(d) 
The front yard shall be measured from the property line to the front face of the building, covered porch, covered terrace or attached accessory building. Eaves and roof extensions may project into the required front yard for a distance not to exceed four (4) feet and chimneys not exceeding ten (10) feet in width may project into the required front yard for a distance not to exceed two (2) feet.
(e) 
Where lots have double frontage, running through from one street to another, a required front yard shall be provided on both streets unless a building line for accessory buildings has been established along one frontage on the plat or by ordinance, in which event only one required front yard need be observed.
Double Frontage Lots
(f) 
If buildings along the frontage of any street between two intersecting streets in any residential district have observed an average setback for that block which is greater or lesser in dimension than the minimum front yard or setback established for the district in which the street frontage is located, then the average setback of all buildings fronting upon such street between two intersecting streets shall establish the minimum front yard requirement. All vacant lots shall be assumed to have a minimum front yard specified for the district in computing the average front yard. These provisions shall not be interpreted as requiring a setback or front yard greater than fifty (50) feet nor shall they be interpreted as requiring any building to observe a front yard of more than ten (10) feet greater than the front setback observed by any building on a contiguous lot. These provisions shall be superseded on any lot where a minimum building line has been established by plat, site plan, or ordinance filed after December 28, 1971.
