Concord FAQ
Martinez FAQ
Where do I sign up to block solicitors?
There is no County list. Post a 'No Soliciting' sign at your door — commercial solicitors must honor it under CCC Chapter 54-6.
Does 'No Soliciting' apply to Girl Scouts or political campaigners?
Non-commercial canvassing is constitutionally protected, but individuals can always ask canvassers to leave, and continued presence becomes trespass.
