Alterations

In alterations, the minimum number is based on the total number of spaces altered or added to a lot. Recommendation: Where a lot is not fully altered, it is recommended that the minimum number of spaces required in new construction for the entire lot be provided where the scope of work provides this opportunity. Normal maintenance is not considered an alteration unless the usability of lots or spaces is affected. For example, where a lot is resurfaced or its plan reconfigured, accessible spaces are required. Maintenance not affecting the usability of spaces, such as repainting existing striping or repairing potholes, does not trigger compliance. Full compliance is required unless it is technically infeasible, such as when providing the required number of accessible spaces will reduce the total below the number required by a local zoning or land use code. In this case, the number of accessible spaces that can be provided is required. (Many zoning boards are willing to grant limited waivers on the total number of required spaces for this purpose.)
