No, according to this article by Chris Elmendorf and Darien Shanske https://www.spur.org/news/2020-12-18/how-solve-transit-budge..., Proposition 218, 26, and the California Vehicle Code probably do not prohibit market pricing of residential parking permits as endorsed by Donald Shoup, since street parking is not just a fee-based service, but city-owned land that the city has the right to rent at market rate. San Francisco just hasn’t tried.
