Chapter 200. Zoning and Land Use Article 1. Rules for All Zoning Districts Measurements and Exceptions Sites Defined A site is any lot or group of contiguous lots owned or controlled by the same person or entity, assembled for the purpose of a single development.
Site Area Site area is the cumulative area of all contiguous lots that the site is composed of. It excludes existing public rights-of-way but does include planned public or private rights-of-way that will be created in the development.
Site Frontage All sites must have at least 25 feet of frontage upon a public street or private street built to public standards.
Density Dwelling Units Allowed
Minimum lot sizes in some districts may appear to allow additional units to be developed on a site beyond what is allowed by sentence a above; however, the zoning district’s allowed density serves as the cap on the maximum number of units on a site.
Accessory Dwelling Units Accessory dwelling units are not counted in density calculations.
Lots Defined A parcel of land either vacant or occupied intended as a unit for the purpose, whether immediate or for the future, of transfer of ownership, or possession, or for development.
3. Flag lot. A lot that does not meet the
minimum frontage and/or width
requirements and where access to thepublic street is by a narrow right-of-way or driveway.
Lot Area The area included within the rear, side, and front lot lines. Lot area does not include existing or proposed rights-of-way, whether dedicated or not dedicated to public use.
Lot Coverage The percentage of total lot area, excluding any streetscape easements provided in accordance with Sec. 401-4.2.A.3, that includes:
Lot Depth The distance between midpoints of straight lines connecting the foremost points of the side lot lines in front and the rearmost points of the side lot lines in the rear.
Lot Frontage
Lot Width
Through Lots
Lot Size
Lot Size Exceptions
Substandard Lots of Record.
Any lot of record existing at the time of the adoption or amendment of the UDO, that has an area or width that is less than is required by the UDO, may be used, subject to the following.

Stormwater Infrastructure Stormwater infrastructure may only encroach into a front or side (street) yard when:
Intersection Visibility Except in districts allowing the construction of buildings or structures to the lot line, an unobstructed view must be provided across the triangles formed as follows:
Vertical measurements are made at the top of the curb on the street or alley adjacent to the nearest side of the triangle or if no curb exists, from the edge of the nearest traveled way.
Heights of fences, hedges, and other continuous foliage are measured from the adjacent top of the street curb, the surface of an alley or the official established grade thereof, whichever is the higher. On interior lot lines, the measurement is from the average grade of the lot line of the property with the lower elevation.
The City Council or Board of Appeals may approve, or may direct as a condition of approval, fences or plantings taller than allowed by paragraph A and B above in order to provide screening between different uses or between like uses upon agreement between the affected parties. No such approval may have the effect of reducing visibility required by this subsection.
See Sec. 401-5.13.D for additional corner sight distance requirements along minor collectors or major thoroughfares Buffer Setbacks Structures, including driveways, parking facilities, and retaining walls must be located at least 5 feet from any buffer required by Sec. 207-2.1.B (Buffer Requirements).
Floor Area Single-Family Dwelling Floor Area Floor area is the sum of finished and conditioned floor area on all floors within surrounding exterior walls of a building. Floor area does not include unenclosed balconies, unenclosed porches, unenclosed stoops, unfinished attics, unfinished basements, garages, or carport.
Floor Area of all Other Uses Floor area is the sum of floor area on all floors within surrounding exterior walls of a building.
Areas of a building not provided with surrounding walls are included in the floor area if such areas are included within the horizontal projection of the roof or floor above. Floor area does not include unenclosed balconies, unenclosed porches, unenclosed stoops, or parking structures.
Height General
Measurement Height is measured as the vertical distance from the mean finished ground level at the front of the building to the highest point of a roof or parapet.
Height Variances Buildings and structures exceeding the height limitations contained in this UDO, and which have not been granted approval by the City Council through a related zoning action, require variance approval by the Board of Appeals.
Height Encroachments The maximum height limits of the district do not apply to:
Street Classification For purposes of this UDO, all of the streets, roads, and highways are classified in the current adopted Gwinnett County Unified Plan or Long-Range Transportation Plan.
Fenestration Fenestration is the minimum percentage of window and door glass that must cover a façade.
Glass used to satisfy fenestration requirements must be unpainted, must have a transparency (visible light transmission) higher than 70%, and must have an external reflectance of less than 15%. Transparency and external light reflectance must be established using the manufacturer’s specifications.
Fenestration is measured from the top of the finished floor to the top of the finished floor above.
When there is no floor above, fenestration is measured from the top of the finished floor to the top of the wall plate.
Window signs must conform to the coverage restrictions of Sec. 207-6 (Signs) .
Adhesive film, fabric, paper, and other materials that are affixed to the window surface or otherwise installed in a way that prevents visibility into the building interior are prohibited. This prohibition does not apply to curtains, shades, Venetian blinds, interior or exterior shutters, and other window treatments that are in operable condition and capable of being adjusted, opened, or closed daily.
Blank Wall Area Blank wall area means a portion of the exterior façade of the building that does not include: fenestration, columns, pilasters, or other articulation greater than 12 inches in depth.
Blank wall area applies in both a vertical and horizontal direction.
Blank wall area applies to ground and upper story street-facing facades only.
Pedestrian Access A pedestrian entrance and walkway providing ingress and egress, operable to residents at all times and operable to customers, visitors, and employees during business hours, is required to meet any street-facing pedestrian entrance requirements. Additional entrances off another street, pedestrian area, civic space, amenity space, or internal parking area are permitted but must have the same or shorter hours of operability as the street-facing entrance.
A street address number must be located above the street-facing pedestrian entrance utilizing numbers that are 6 to 10 inches in height. When multiple entrances exist on a street-facing façade, only one address is required.
An angled or mitered pedestrian entrance may be provided at either corner of a building along the street to meet the street-facing pedestrian entrance requirements.
These requirements may also apply abutting a civic space in TC Districts, as determined by the Director. In making this determination, the Director must consider the use and design of the civic space, the use of the proposed building, and the public health, safety, and welfare.
A front porch or stoop is required to meet the street-facing pedestrian entrance requirements when required by building type.
