Defines "administrative office space" as organizational headquarters or auxiliary office space used by nonprofit organizations to provide onsite supportive services and other nonprofit operations, including parking necessary to serve the office space.

Changes the nonresidential floor area requirement for developments with more than 20 units from 3 percent of "total nonresidential floor area" to 3 percent of "total floor area" for onsite supportive services.
