I have posted door hangers in deed restricted communities with no problems. Even if there is a no soliciting sign posted you are not violating any law. I know I tried to keep TrueScam(green) out of my community and off my property with no luck. They still come and leave a hanger telling me they can get rid of the non-existant weeds in my lawn. Some day I will catch the SOB and tell him about himself and the company he works for!
