[Note A] | = | The minimum average lot area per apartment dwelling shall be reduced to 750 square feet if a lot will include six or more dwelling units, and each dwelling unit will be restricted to occupancy by at least one person age 62 or older or a person with disabilities, and there is no occupancy by any person under age 18 years old. |
[Note B] | = | If an existing rear or side alley is available or could be feasibly extended, it shall be used for access to parking spaces for the lot instead of a front yard driveway, unless the City determines that another access is more appropriate as part of a subdivision or land development approval. If two or more side-by-side, off-street parking spaces are located in the front yard of a townhouse or if garage door(s) for two or more vehicles face onto the street in the front of the townhouse, then the minimum building width per dwelling along such street shall be a minimum of 24 feet. A maximum of 60% of the land area between the front of each townhouse or semidetached dwelling and the street right-of-way line shall be used for vehicle parking and driveways. |
[Note C] | = | The average density provisions are intended to allow flexibility in the placement of individual dwelling units, regardless of whether the homes are condominium or fee-simple, and regardless of whether public streets, private streets or parking courts are used. No minimum lot area applies for each individual dwelling unit, provided that the overall density requirements are met. Each single-family, semidetached or townhouse dwelling shall still be able to meet the minimum front yard, side yard, rear yard and lot width as if each dwelling was on its own fee simple lot. |
The minimum average lot area per dwelling unit establishes the maximum number of units permitted on a tract of land. The total lot area of the tract prior to development is used. The area occupied by existing street right-of-way of existing streets and alleys is then deleted. The following areas are not required to be deleted from the lot area: right-of-way of proposed streets and alleys and areas of parking courts, common open space and stormwater detention basins. The resulting lot area is then divided by the average lot area per dwelling unit to result in the maximum number of dwelling units allowed on the tract. | ||
[Note D] | = | Setbacks shall be measured from the legal street right-of-way, after any subdivision or land development has been completed. An unenclosed front porch or deck may encroach up to 10 feet into the minimum front yard. This porch or deck may be covered by a roof. Steps, stoops and ramps for persons with disabilities may also encroach into this setback as necessary to provide access, which may be beyond 10 feet. |
[Note E] | = | For townhouses and semidetached dwellings, the maximum building and impervious coverage requirements may be met as an average across a tract after development, as opposed to regulating each individual lot. |
[Note F] | = | The following exceptions shall apply: |
For accessory structures and uses, see § 550-22 below. | ||
Structures shall not obstruct minimum sight clearance at intersections, as provided in Article XVII. | ||
See § 550-92 regarding extension of nonconforming setbacks. | ||
See § 550-91 regarding permitted reductions in setbacks to reflect average setbacks of adjacent buildings. | ||
[Note G] | = | Abutting lots in common ownership may be calculated together to show compliance with the maximum coverages. |
[Note H] | = | Except 0 feet at the shared lot line of lawfully attached dwellings, such as along the lot line of semidetached dwellings or townhouses, or where a new attached building is constructed that replaces a previous building that was attached to the same adjacent building, or where the City approves adjacent business buildings to be constructed on a lot line as part of a subdivision or land development. |
[Note I] | = | Except 20 feet side and 25 feet rear for a principal business from a lot in a residential district that is occupied by a principal dwelling that is not in common ownership. Such side or rear yard shall be increased to 60 feet from such a lot for any building area or land area used for manufacturing, bulk storage of highly hazardous substances, industrial outdoor processing or a tractor-trailer truck loading dock. |
[Note J] | = | A minimum three feet building setback is required from an approximately parallel door or window of a building on another lot, unless a larger setback is required under the Construction Code.[1] |
[Note K] | = | Individual lots may be approved with a minimum lot area of 1,500 sq. ft. or smaller condominium parcels as part of a unified subdivision or land development plan. |
[Note L] | = | The minimum lot width is measured at the part of the lot where the minimum building front yard setback applies. If a building is placed further back from the street, it will not change where the lot width is measured. |
Abbreviations: | sq. ft. = square feet. |
