From the City of Sacramento City Express blog: https://sacramentocityexpress.com/2019/11/18/traffic-and-parking-enforcement-begins-for-shared-e-scooters-e-bikes-on-nov-19/.

The city will be enforcing both parking and traffic for the electric assist bike share JUMP, and the JUMP and Lime electric scooters. Many people are still riding the scooters on sidewalks, so I would expect citations for that. Under state law, not Sacramento law, scooters must be ridden on the street. The amount of parking that endangers or impedes walkers has fallen off over time, so there should be much less of that, but it will be interesting to see how exactly that will be enforced. The city still does not have sufficient bike parking, particularly in neighborhoods but even in commercial and mixed areas, and though it has installed a few bicycle and scooter corrals, they are far from enough.
