2019 California Standards for Accessible Design Guide (effective January 1, 2020 with July 1, 2021 amendments)

Advisory 11B-208.2.1 Hospital outpatient facilities. The higher percentages required for hospital outpatient facilities or rehabilitation facilities specializing in treating conditions that affect mobility and outpatient physical therapy facilities (indicated in Section 11B-208.2.2 below) are intended primarily for visitor and patient parking. If there are separate lots for visitors or patients and employees, the 10% or 20% requirement shall be applied to the visitor/patient lot while accessible parking could be provided in the employee lot according to the general scoping requirement in Table 11B-208.2. If a lot serves both visitors or patients and employees, 10% or 20% of the spaces intended for use by visitors or patients must be accessible.

At hospitals or other facilities where parking does not specifically serve an outpatient unit, only a portion of the lot would need to comply with the 10% scoping requirement. A local zoning code that requires a minimum number of parking spaces according to occupancy type and square footage may be an appropriate guide in assessing the number of spaces in the lot that "belong" to the outpatient unit. These spaces would be held to the 10% requirement while the rest of the lot would be subject to the general scoping requirement in the table. Those accessible spaces required for the outpatient unit should be located at the accessible entrance serving the unit. This method may also be used in applying the 20% requirement to hospitals or other facilities where only a portion or unit provides specialized rehabilitation or physical therapy treatment or services for persons with mobility impairments. ◼
