What rules govern street parking in HOAs where no signs are posted prohibiting overnight parking, etc.? Normally, persons with mobility disabilities would be expected to use their driveways or garages and not park on the street. If you need parking accommodations, you would need to provide the HOA with written verification of your disability and explain why you need to park on the street (instead of in your driveway or garage). California law says where there are 500 parking spaces 2% need to be designated as spaces for people with disabilities. The HOA might be able to relocate their parking space to help them with their mobility limitations.
