(Ordinance 2020-59, adopted 9/8/2020)
A. 
The minimum lot area for the various zoning districts shall be in accordance with the individual districts except that a lot having less area than herein required which was an official "lot of record" prior to the adoption of this ordinance, may be used for a single-family dwelling and no lot existing at the time of passage of this ordinance shall be reduced in area below the minimum requirements set forth in the respective district.
B. 
Location of dwellings and buildings. Only one main building for single family and two-family use, with permitted accessory buildings, may be located upon a lot or unplatted tract.
C. 
Every means of access shall have a minimum lot width of 25 feet at the property line.
D. 
Whenever two or more main buildings, or portions thereof, are placed upon a single lot or tract and such buildings do not face upon a public street, the same may be permitted when the site plan for such development is approved by the Planning and Zoning Commission so as to comply with the town subdivision regulations' requirements for platting.
E. 
No parking area, storage area, or required open space for one building shall be computed as being the open space, yard, or area requirements for any other dwelling or other use.
F. 
Residential density calculations. The maximum permitted residential densities for the TH and MF Districts shall be calculated using the net acreage of the site to be developed.
Net acreage shall not include the following:
•
Right-of-way dedicated for major thoroughfares.
•
Required parkland dedication.
•
Detention.
•
Land used for non-residential purposes.
Net acreage may include the following:
•
Non-reclaimed floodplain.
•
Private open space.
•
Park dedication in excess of minimum park dedication requirements.
•
Detention ponds that contain a constant water level, are landscaped, or otherwise treated as an amenity for the development, as determined by the Director of Development Services or his/her designee.
The minimum dwelling unit area of a residential unit shall be as specified in each residential zoning district in article 2 of this ordinance. Dwelling unit area is defined as that area devoted to the living area in a residence or dwelling unit and is exclusive of porches, enclosed or open breezeways, storage area or closets, garages, or other non-living space. The minimum dwelling unit area will generally be that space which is air-conditioned.
A. 
On corner lots, the front yard setback shall be observed along the frontage of both intersecting streets, unless shown specifically otherwise on a final plat.
B. 
Where the frontage on one side of a 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 zoning district for the entire frontage.
C. 
Where a building line has been established by a plat approved by the Town of Prosper or by ordinance prior to the adoption of this ordinance, and such line required is a greater or lesser front yard setback than prescribed by this ordinance for the zoning district in which the building line is located, the required front yard shall comply with the building line so established by such ordinance or plat provided no such building line shall be set back less than 20 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 or a porch without posts or columns may project into the required front yard for a distance not to exceed three feet, and subsurface structures, platforms or slabs may not project into the front yard to a height greater than 30 inches above the average grade of the ground under the structure (See article 5, § 5.2.3, Illustration I).
E. 
Where a lot fronts and backs to two different streets, 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 (See article 5, § 5.2.3, Illustration J).
F. 
In all single family and 2F Districts, the minimum front yard setbacks for all lots fronting onto the same street along a block shall be staggered such that one-third of the lots have a front yard setback that is reduced by five feet, one-third of the lots have a front yard setback as defined in article 2, and one-third of the lots have a front yard setback that is increased by five feet. Not more than two lots in a row may incorporate the same front yard setback. The average setback along the block shall equal the required setback for the particular zoning district. The lots with an increased front building line may also decrease the rear building line by five feet to maintain the necessary building pad depth. The purpose of this requirement is to produce a variety of front yard setbacks along a street, creating a more pleasing street presence and appearance of houses in the subdivision. In no case shall the front yard setback be less than 20 feet. The front setbacks for each lot shall be designated on the final plat. (See article 5, § 5.2.3, Illustration K)
G. 
Visual clearance shall be provided in all zoning districts so that no fence, wall, architectural screen, earth mounding or landscaping 30 inches or higher above the street center line obstructs the vision of a motor vehicle driver approaching any street, alley, or driveway intersection.

J. 
The minimum front yard in single-family and two-family zoning districts may be reduced by ten feet in the following circumstances. In no case shall the reduction cause the minimum front yard to be less than 15 feet.

In such case, a building line shall be designated on the plat approved by the Town of Prosper containing a side yard of 15 feet or more. On lots that were official lots of record prior to the effective date of this ordinance, the minimum side yard adjacent to a side street shall comply with the minimum required side yard for the zoning district.
