Gaithersburg residents can post No Soliciting signs to indicate they do not wish to be contacted by door-to-door salespeople. Solicitors with city permits are required to respect posted No Soliciting signs and leave the property without knocking. Montgomery County does not maintain a formal no-knock registry, but the city enforces compliance with posted signage through its solicitation ordinance.
Under the Gaithersburg Code of Ordinances, permitted solicitors must respect No Soliciting signs posted at residences. When a sign is clearly displayed, the solicitor must not knock, ring the doorbell, or otherwise attempt to contact the resident. Failure to comply is a violation of the solicitation permit conditions and may result in permit revocation. The city does not maintain a centralized no-knock registry like some jurisdictions, but the posted sign serves as the resident's declaration of refusal. Political canvassers and religious visitors are generally not bound by No Soliciting signs under First Amendment protections, though they must still leave immediately when asked. HOA communities in Gaithersburg often provide additional mechanisms for restricting solicitation. Some HOAs maintain community-level no-solicitation policies that apply to all visitors entering the neighborhood. In gated or controlled-access communities, solicitors may be screened at entry points. Residents who experience persistent unwanted solicitation should contact Gaithersburg Code Enforcement at 301-258-6330 or the Montgomery County Police non-emergency line at 301-279-8000 if the behavior becomes aggressive or threatening.
Ignoring a posted No Soliciting sign is a violation of the city solicitation ordinance, subject to fines and potential permit revocation. Refusing to leave after being asked is criminal trespass under Maryland law. Aggressive or threatening solicitation may be reported to police.
