A notice was sent out to Realtors that Paso Robles will be enforcing their sign ordinance. This is not a surprise as there are getting to be a lot of real estate signs being installed in areas other than at the home for sale. Plus, with the Days on Market increasing, some of these signs are there for 6+ months.
Most (all?) cities allow a sign to be placed on the property and temporary (Open House) signs on weekends. Signs placed on private property or public right of way at intersections or other places aren’t allowed but cities don’t usually enforce their sign ordinace unless someone complains.
