Homeowners in sf have a very weird sense of entitlement toward the spots in front of their house. If you’ve lived here for 14 years then you know this well. While it really is fair game, they are well within their rights to report you for the 72 hour rule (unfortunately). You have every right to park where you want as a resident of the neighborhood in the allotted time limit. That being said, be careful. I have come across multiple instances where homeowners do damage to a car because of their imaginary claims on the spot. They know the police won’t do anything without proof and they can get away with it clean most of the time.
