No-Solicitation or No-Knock signs are legally enforceable in Pennsylvania. Allegheny County municipalities including Pittsburgh recognize posted signs; ignoring them can support trespass charges under 18 Pa.C.S. 3503.
While PA has no statewide Do Not Knock registry, clearly posted No Solicitation or No Trespassing signs create constructive notice. PA 18 Pa.C.S. 3503(b)(1)(i) makes defiant trespass a summary offense when notice is given by actual communication or posting. Many municipal peddler ordinances (Pittsburgh 717, Mt. Lebanon) explicitly require solicitors to honor posted signs and cease further contact. Some municipalities maintain voluntary Do Not Knock registries; check with local police.
Defiant trespass 18 Pa.C.S. 3503: summary offense up to 300 dollars. Repeat or aggressive violations may be prosecuted as third-degree misdemeanor (up to one year jail). Municipal solicitor license revocation possible.
