Parking requirements
No land shall be used or occupied, and no structure shall be erected or used, unless the off-street parking spaces required herein are provided. Such parking spaces are not required (a) for any structure or use existing prior to the effective date of this ordinance or any amendment thereto, provided however, that parking spaces as specified in this ordinance shall be provided subject to the requirements of this section for any enlargement, alteration or change to any such existing structure or use and also provided that no existing parking shall be decreased below the minimum requirements herein, or (b) for any structure or use for which an application for master plan, preliminary plan, or final plan approval was submitted prior to the effective date of the amendment to this ordinance that first established the off-street parking space requirements described in parking schedules 801 A and 801 B.
The number of off-street parking spaces required shall be determined by reference to parking schedule 801 A (residential uses) and schedule 801 B (nonresidential uses) below. As noted in schedule 801 A, the required number of spaces required for some residential uses will be reduced if the proposed use meets the specified thresholds for inclusion of deed-restricted affordable housing and/or is within the specified distance from public transit.
Alternatives to the parking standards shown in the schedules below shall be considered by the board upon submission of an application for a special use permit, which shall include a parking demand and impact assessment, as described in section 514.13(b).

Notes:
1. Affordable housing bonus. Residential developments that include a minimum of 15 percent of units designated as deed-restricted affordable housing units for households earning 60 percent of AMI or less are eligible for a 25 percent reduction in required parking for each affordable unit. A special use permit is not required, but applicants must provide evidence of the deed restrictions or a signed commitment to provide the number of deed-restricted affordable units for which they are seeking a reduction in parking.
2. Transit oriented development bonus. Residential developments that are located within 1,500 feet walking distance of a fixed-route public transit route stop are eligible for a 25 percent reduction in required parking. A special use permit is not required, but applicants must provide a map that illustrates the distance from the proposed development to the transit stop.
3. Off-site parking spaces. Parking requirements may be satisfied by spaces at an off-site location in accordance with the requirements for a special use permit as described in section 514.13(c).
4. Shared parking. Parking requirements may be satisfied by spaces shared with other uses in accordance with the requirements for a special use permit as described in section 514.13(b).
5. Maximum lot coverage. These parking requirements do not supersede the maximum lot coverage (building footprint plus the area of all paved surfaces) shown in section 401 residential zones. If the minimum number of parking spaces cannot be provided without exceeding the maximum lot coverage, then applicants must apply for a dimensional variance for the area in excess of the maximum lot coverage and submit plans that show permeable paving material will be used for an area equal to or greater than the excess. The maximum number of spaces will be allowed only if they can be provided without exceeding the maximum lot coverage.
