Subdivision Regulations
In reviewing the architectural design of commercial, mixed-use, and institutional buildings the Plan Commission considers:
All new nonresidential buildings or building additions located within an Industrial District must comply with the following:
The maximum length of a single-family residential subdivision block is 1,250 feet, except where an internal street or frontage road parallels an expressway or arterial.
| Zoning District | Min. Open Space Required |
| R1 | 5% |
| R2 | 8% |
| R3 | 10% |
| R4 | 12% |
| R5 | 15% |
| MU-OSR | 50% |
| MU-COR | 10% |
Developments must integrate an interior and exterior pedestrian network comprised of concrete sidewalks and/or asphalt side paths for pedestrian transportation and recreation. This network must be consistent with the Avon Bicycle and Pedestrian Plan. Details about when and where sidewalks are required are indicated in the Avon Bicycle and Pedestrian Plan. If not indicated, the Administrator determines the appropriate sidewalk or side path requirements.
Street lights must be installed within the rightof-way at all intersections where internal streets intersect with arterial streets or collector streets. These streetlights must meet the Town of Avon Engineering and Construction Standards.
7.27 Single-Family Architectural Standards Tables
Architectural Standards for Single-Family Dwellings. New single-family dwellings must meet the following architectural standards indicated in Table 7-1, 7-2 & 7-3.
Table 7-1
| Architectural Requirements |
| Window Requirements. On homes exceeding one story, front facades must have at least four windows, side facades must have at least two windows, and rear facades must have at least four windows. On one story homes, front facades must have at least two window openings, side facades must have at least one window, and rear elevations must have at least two windows. |
| Masonry Wrap. A front façade masonry wrap is required on all homes. At a minimum, this is a masonry wainscot from the first-floor windowsill and continuing down to the foundation. On those lots that adjoin a common area, public park or public street, masonry wrap shall include any façade visible from common area, public park or public street. |
| Roof Overhangs. The main roof of the home must have roof overhangs at least 11”. (See Note 1 below) |
| Building Articulation. The front façade must have projections or recessions. This may be accomplished using (a) one offset at least 4’ deep and a minimum height equivalent of one story or (b) two offsets at least 2’ deep and a minimum height equivalent of one story. |
| Window Trim. Windows must have decorative trim, either (a) wood or composite trim at least 3 1/2” wide around all windows or (b) decorative trim detailing (e.g. arches, cornices, moldings, etc.), as architecturally appropriate. Shutters may be substituted for trim on sides of the windows and windows surrounded by brick or stone shall not require window trim. Shutter may be substituted for trim on the sides of the windows and windows surrounded by brick or stone shall not require window trim. |
| Corner Lots. Corner lot side elevations facing the street must have architectural detailing similar to the front façade (e.g. window trim, gable detailing). |
| Anti-Monotony Standards |
| All front facades and perimeter lot facades visible from, and adjoining a perimeter street, common area or park, must meet the following anti-monotony standards: (See Note 2 below) |
| ▪ The same elevation and color scheme cannot be used on lots adjacent to the subject lot. |
| ▪ Homes two lots away from the subject lot cannot use the same color scheme. |
Notes:

| ▪ The same elevation and color scheme cannot be used on lots adjacent to the subject lot. |

| | Use of shutters on all windows of the façade, where possible. |
| | A set of at least 3 bullet windows. |
| | A front door with a transom window and side lights. |
