[1] When a range of floor area ratios is shown, the lowest is for a single-story building and the highest is the maximum achievable in the district for taller buildings.

[2] The maximum floor area ratio is increased by the attic allowance which provides up to 20 percent additional FAR for space beneath a pitched roof that has structural headroom of between five and eight feet.

[3] The floor area ratio shown is exclusive of the bonuses for plazas, arcades, and other amenities which can increase FAR by up to 20 percent.

[4] When a range of open space ratios is shown, the lowest is the minimum required at the lower floor area ratio, and the highest is the minimum required at the highest floor area ratio shown.

[5] When a range of required lot areas per room, or rooms per acre, is shown, the first number is the density permitted at the lowest open space ratio shown, and the second is the maximum density permitted in the district.

[6] The lot area requirement and number of rooms per acre shown are exclusive of the bonus for plazas or arcades, which can reduce the lot area requirements up to 17 percent and increase the possible rooms per acre up to 20 percent in this district.

[7] Dwelling units shown for R3 through R10 districts are presented for illustrative purposes only. Districts R3 through R5 are computed using the density measure (minimum number of square feet of lot area required for each dwelling unit); density in R6 through R10 districts is computed by dividing the maximum number of zoning rooms allowed per acre by the minimum number of zoning rooms allowed per dwelling unit (2.5).
