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

1.The maximum number of dwelling units allowed on a site is calculated by either:

a.Multiplying the site area by the maximum number of units per acre allowed in the zoning district, when applicable; or

b.Conforming to minimum lot sizes.

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.

2.The maximum number of dwelling units allowed on a site or portion of a site located within a floodplain must be further reduced when required by the FH district standards of Sec. 205-3.3.A.

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.

Lot types include the following:

1.Corner Lot. Any lot with frontage on two streets at their intersection.

2.Interior Lot: A lot with frontage on only one street.

3.     Flag  lot.  A  lot  that  does   not     meet  the

       minimum        frontage          and/or    width

       requirements      and  where     access  to    the

public street is by a narrow right-of-way or driveway.

4.Through Lot. A lot other than a corner lot with frontage on two or more streets.

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:

1.The horizontal area of the building footprint measured within the outside of the exterior walls of the ground floor of all principal buildings and any roofed accessory buildings on the lot; and

2.Any impervious parking areas, driveways, walkways, steps, terraces, uncovered patios and decks, swimming pools, and any similar features. The Director may establish rules for determining the extent to which partially pervious materials are exempt from lot coverage.

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

1.Defined. The portion of a lot adjacent to a street or specified courtyard for a cottage court.

2.Minimum Frontage

a.Every lot must have at least 25 feet of frontage upon either a public street, a private street built to public standards, or a specified courtyard for a cottage court, except when less frontage is allowed by zoning district regulations or when more frontage is required along cul-de-sacs.

b.Every lot along a cul-de-sac must have at least 35 feet of frontage, measured along a straight line along the chord of the arc at the right-of-way line.

Lot Width

1.Defined. The distance between side lot lines measured at the minimum required front yard setback, except as provided for cul-de-sacs below.

2.Lot Width along Cul-de-Sacs. For a lot with the majority of its frontage on a cul-de-sac, the lot width may be measured at the minimum required front setback line or at a line parallel to said setback line at no more than twice the minimum front setback distance from the street.

Through Lots

1.Through lots are required for residential subdivisions along major thoroughfares where internal access can be provided, except as otherwise allowed by clause 2 below.

2.Interior and corner lots are allowed along major thoroughfares in the TCO, TC, MU, and NR districts when these lots have internal access from an alley or shared driveway.”

3.When a through lot is required by clause 1 above, a no-access landscape strip must also be provided when required by Sec. 207-3.2.C.

Lot Size

1.New lots must conform to the size requirements of the applicable zoning district, except as otherwise allowed by paragraph I below.

2.No lot, even though it may consist of one or more adjacent lots in the same ownership at the time of passage of this UDO, may be reduced in size so that its width, size of yards , lot area per dwelling unit, or any other requirements of this UDO are not maintained. This does not apply when a portion of a lot is acquired for public use.

3.New lot size is determined by Sec. 401-4.2.A.3.c on existing public streets where there is insufficient right-of-way for the required streetscape improvements and an easement is provided in accordance with Sec. 401-4.2.A.2.

Lot Size Exceptions

1.No lot served by a septic tank may have a lesser area than that approved by the Environmental Health Section for safe drinking water and septic tank operation.

2.Lots used exclusively for common areas, open spaces, private alleys, or stormwater facilities are exempt from lot size requirements.

3.Lots used exclusively for subdivision entrance sign or subdivision entrance landscape features are exempt from lot size requirements when:

a.The lot is located at an entrance to the subdivision as an "island" in the right-of-way of a local or minor collector street; and

b.The subdivision provides a mandatory homeowner association or non-residential equivalent that is responsible for maintaining the lot in perpetuity; and

c.Right-of-way with a minimum width of 6 feet from the back of the curb is provided adjacent to the perimeter of the lot.

d.Landscape plantings are not allowed in the right-of-way, except as otherwise provided in this UDO within the streetscape planter by Sec. 401-4.2 Streetscape Required .

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.

1.Individual Lot Not Meeting Minimum Lot Size Requirements.

a.Except as set forth in sentences b and c below, in any zoning district where single-family detached dwellings are permitted, any lot of record existing at the time of adoption or amendment of the UDO which has an area, width or depth less than that required by the UDO may be used as a building site for one single-family detached dwelling.

b.In the case of such a lot, when it is not possible to provide the required side setbacks and at the same time build a minimum width single-family detached dwelling, the Board of Appeals is authorized to grant a variance reducing the side setback requirements for such lot the minimum amount necessary for a reasonable dwelling, but in no case may each of the side setbacks be less than 5 feet in width or the new structure located less than 10 feet from an principal structure on an adjacent lot.

c.In the case of such lot, when the lot was previously approved in a final plat for use as a common area, open space, private alley, stormwater facilities, or similar amenity or infrastructure use, it may not be used as a building site for one single-family detached dwelling.

2.Adjoining Lots. When two or more adjoining lots of record with continuous frontage are in one ownership at any time after the adoption or amendment of the UDO and such lots, individually, have an area or width that is less than is required by the UDO, then such contiguous lots are considered as a single lot or several lots of the minimum width and area required by the zoning district in which they are located and must be combined.

Building Setbacks Type of Setbacks

1.There are four types of setbacks – front, side street , side interior , and rear.

2.Building setbacks apply to both principal and accessory buildings or structures, except where it explicitly states otherwise in this UDO.

Measurement of Building Setbacks Building setbacks are measures as follows, except when paragraph C below applies:

1.A front setback is measured at a right angle perpendicular to the front lot line, except as otherwise required by clause 7.

2.A side street setback is measured at a right angle perpendicular to the side street lot line, except as otherwise required by clause 7.

3.A rear setback is measured at a right angle perpendicular to the rear lot line.

4.Lot lines which are not front, side street , or rear lot lines are considered side interior lot lines for the purpose of measuring setbacks. Side interior setbacks are measured at a right angle perpendicular to the side interior lot line.

5.Setbacks must be drawn using an extension of a line perpendicular to the lot line until they intersect with another setback line.

6.Where street right-of-way dedication occurs, setbacks are measured from the final lot line.

7.Where a streetscape easement is provided in accordance with Sec. 401-4.2.A.3, setbacks must be measured from the easement.

Irregularly Shaped Lots The Director will determine how setbacks apply to irregularly shaped lots.

Front Setback Exceptions The following applies in all districts except the TCO, TC, MU, and NR districts.

1.Front setback requirements do not apply on lots where the average depth of the front yards of existing buildings on adjoining lots located wholly or partially within 100 feet on each side of such lot within the same block and zoning district and fronting on the same side of the street is either more or less than the minimum required front setback.

2.If the average depth of the front yards is more than the required front setback, then the lot’s required front setback is the average depth of the front yards of the above-referenced buildings but not more than 150% of the otherwise required front setback.

3.If the average depth of the front yards is less than the required minimum front setback, then lots required front setback is the average of the front yards of the aforementioned buildings.

Building Setback Encroachments All principal buildings and structures must be located at or behind the required zoning district setbacks, except as listed below. Unless specifically stated in this UDO, no building or structure may extend into a required easement or public right-of-way.

3.Within these triangles, there may be no sight obscuring wall, fence, entrance sign, marker, or foliage higher than 30 inches above grade, or in the case of trees, foliage lower than 8 feet.

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.

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.
