I’m living in a quiet residential area in a small town, the property is located along a row of semi-D houses where a sign states “residents parking only”. Running parallel to the houses on the other side of the green there is paid parking in place. Although there is no parking space specifically allocated to each house typically everyone living here just parks outside their own house and there are no issues. Recently there are unknown cars parking along the “resident parking” zone, more often than not when I come home from work there is a different car parked in front of my house making it a long walk to bring in groceries etc and at times resulting in me having to park in the paid zone. It’s getting on my nerves and I would like to know if I have any right to put up a “no parking” sign or “resident parking only” sign outside my house. Although it is a public road why do they have a sign up indicating it’s residential parking only if it’s not being enforced. Any advice would be appreciated
