In the age of cellphones and the Internet, we’ve become unaccustomed to the idea of a knock at the door. From the other side, is it weird to just go up and knock on someone’s door anymore? Is it Illegal? Are you trespassing?

It is not illegal to knock on someone’s door. However, repeated knocking can turn into harassment. Simply knocking, though, is not seen as a legitimate interference in a homeowner’s life.

Of course, the response will depend on your intended purpose. An interest in talking with the person that lives there is legal. Soliciting and police investigation are also legal.

What constitutes a ‘good neighbor’ can be different to different people. In general, everyone seems to want to be good neighbors.

With that said, the following breaks down general guidelines on legal activities and common practices in regards to knocking on someone’s door.

Greeting New Neighbors

Perhaps you just moved to the neighborhood and are going around introducing yourself to your neighbors. Or, you want to meet the new folks that bought the house across the street.

In pretty much all instances, this is completely legal. If the purposes for knocking on someone’s door is merely to introduce yourself, legality should not be a concern to you.

After all, you would want to be on good terms with your new neighbors so feel free to knock on their door.

Don’t Knock Too Much

With this comes some caveats that should be obvious, but for clarity let’s run it down. Being a good neighbor can also mean knowing which neighbors want to be left alone and not bothered.

If a neighbor requests that you not knock on their door, any repeated attempts could be looked at as harassment. If you refuse to leave after they have asked you to, then that is for sure trespassing.

Also, having children could complicate things. If they are in the neighbor’s yard without permission, it could cause issues. Hopefully, most neighbors would understand in most circumstances. In some cases, it could be construed as trespassing.


While ordinances and regulations vary from state and county, soliciting is legal. This can include door to door salesmen, political endorsements, charitable requests, and religious invitations.

With that does come some limitations. The homeowner does have the right to refuse service from any of these solicitors. They can request that those solicitors not return to their residence. If they do return on numerous occasions, it can be seen as harassment and legal action can be taken.

Get Your License

In order to solicit in a lot of jurisdictions, the solicitor has to have a license. These could come with restrictions that keep soliciting relegated to certain time periods. It’s usually best to look up your local regulations if you have a question.

‘No Soliciting’ Signs

Do these work? Usually, most solicitors will see a No Soliciting sign and move on. They aren’t looking for a confrontation. The bigger question is are they legally binding?

The answer seems to be Yes and No. Legally you are free to post one. Any action it pertains to falls on the standard trespassing laws that already exist.

The sign mainly works as an indication to the solicitor, showing they won’t get very far with their pitch. Usually solicitors will try to save themselves the time if they already know the answer will be NO. If they try anyway, it can be pretty common to just not answer the door. Better luck next time.

All Or Nothing With Solicitors

One thing to keep in mind is that a no soliciting sign can be seen as an all or nothing situation. You can’t target one specific group. A sign reading “No Soliciting From Jehovah’s Witnesses” would be seen as accepting soliciting from anyone else. It would appear as you are open to all solicitation and can then be used as a free-speech argument.

Again, it’s important to check with your local regulations about soliciting to check what can and can’t be done. If you’re a homeowner, be aware of what you have the right to do about them. As a solicitor, learn what is allowed of you when contacting people in the neighborhood you are working in.

No Trespassing Signs

In general, it’s usually a good idea to not disturb neighbors who have a No Trespassing sign posted. For the sake of discussion though, let’s look at what the actual law is about knocking.

One thing to think about is if the property is gated or locked down in any way. Does the property have a fence and/or gate? If so, the homeowner has revoked the public’s invitation to access their front door.

If the property is open but still has signs posted, it’s likely not a good idea. They have left it open for such things as mail delivery or any business that the resident has initiated.

No Signs Needed

Some states even allow signs that aren’t even signs. If a resident has a dividing area painted with bright orange paint, that can indicate no trespassing.

This usually applies to large plots of land that run up against state-owned land. It can help identify natural markers like streams or hills as being on private property.

You could be wandering a state park and find a bright orange pole. This indicates you are entering private property and could be subject to trespassing laws. Usually, these are placed within 200 feet of each other and indicate where the property line is.

Dealing With Police Questioning

One of the things that many have gone back and forth on is Police questioning. Can a No Trespassing sign can keep the police from knocking on someone’s door? Commonly, it does not keep the police from doing so. However, a resident is not required by law to answer a door knocked on by an officer without a warrant.

Also, a police officer cannot bring a K9 onto the property without a warrant. Doing so during a ‘knock and talk’ would be considered a search and would be illegal. This violates the 4th Amendment which protects citizens from unlawful search and seizure.

Serving Process

If you are serving process, do not trespass. With that said, it is perfectly fine to be in areas that are obviously open to the public, such as the sidewalk. The path that extends from the sidewalk to the front door of a business or home is also generally implied to be for public use.

As you approach the home, the expectation is that you ring the doorbell or knock. The same guidelines apply for serving process at a business. Any area before the front desk is, again, inferred to be open to the public. However, crossing behind the front desk of a business can be considered trespassing. So, proceed with caution.

Serving process in areas that are evidently open for the public doesn’t give you complete freedom. You cannot inhibit anyone’s expectations of privacy from a public use area. This includes peeking through, or even knocking on, windows, attempting to find an alternate entrance, or touching mailboxes.

Likewise, sidewalks and roads may be considered public areas, but it is unlawful to block someone’s driveway.

When You’re Unsure

A good rule of thumb to keep in mind is to ask yourself this: “If I owned this property, what locations would I be uncomfortable with a stranger inhabiting?” Also, “what actions would I be comfortable with a stranger doing while inhabiting these places?”

Remember that, when it comes to determining if a property is accessible, your own safety comes first. Consider your actions, be mindful, and try to think in terms of how your actions may be seen by the homeowners. Finally, always err on the side of caution.

Related Questions

Is it illegal to knock and run on someone’s door?

Yes. While most people would consider this a harmless prank, it can warrant police action. This could be charged as trespassing as the intent isn’t to interact with the resident, but actually harass them. Repeated offenses could even garner jail time.

Is it illegal to knock on someone’s door after a certain time?

No. Depending on the person, they may ask you to not knock after a certain time. At that point, repeated knocking could be considered harassment and could end up getting the police involved.

As a resident who is worried about people knocking on my door are there good solutions?

Yes! There are ways to check who is at your door. And also where you mount them should be considered to get the best use out of them.

What Have We Learned?

Friendly neighbors make good neighbors. If they are one of the people you interact with frequently, feel free to knock away.

If they have a NO TRESPASSING sign up, then it’s probably better to just leave them alone. With that all in mind, try and make the best common-sense decisions.

Finally, check with your local ordinances and regulations as they can be different from county-to-county.
