What the law actually says about taking photos
In most of the United States, you can photograph anything you see from a public place — a street, a park, a sidewalk — without asking permission first. This includes people, buildings, and events. The legal rule is straightforward: if you are standing where you have a right to be, and you can see it without trespassing or breaking a window, you can point a camera at it.
The moment changes when you step onto private property or try to photograph someone in a place where they have a reasonable expectation of privacy — a bathroom, a changing room, a bedroom, a doctor's office. The rules also shift when you want to use a photo commercially, sell it, or publish it in a way that suggests someone endorses a product or service. State laws vary on these points, and some cities have added their own rules, so the specific answer depends on what you want to photograph and what you plan to do with the image.
Key Takeaways
- You can photograph people and property from public spaces without permission in most states, but private property owners can refuse and ask you to leave.
- Photographing someone in a private space where they expect privacy — a bathroom, changing room, or medical office — is illegal in all states and can result in criminal charges.
- Using someone's photo to advertise a product, service, or business usually requires their written permission, even if you took the photo in public.
- Police officers and security guards cannot legally force you to delete photos taken from public property, though they may ask and may detain you if they suspect a crime.
- State laws differ on whether you need permission to record audio alongside video, so check your state's rules before recording conversations.
Photography in public spaces and on public property
Public streets, parks, beaches, and sidewalks are places where you have a legal right to be, and photographing from these locations is protected in nearly every state. You can photograph strangers, buildings, landmarks, protests, police activity, and events without asking permission first. This protection exists because courts have recognized that photography is a form of free speech and that public spaces are where that speech matters most.
The catch is that the property owner's right to exclude people from their land can override your right to photograph. If you are standing on a public sidewalk and a store owner asks you to stop photographing their storefront, you must leave when asked — but you can photograph from the sidewalk itself. If you refuse to leave private property after being asked, you can be arrested for trespassing, even if you were only taking pictures.
Photographing police officers performing their duties in public is legal, though officers sometimes claim it is not. You have the right to record police activity from any place you have a legal right to be. However, officers can order you to move back for safety reasons, and they can arrest you if you interfere with their work or refuse a lawful order to move. The photograph itself is legal; the arrest would be for obstruction or failure to obey, not for taking the picture.
When you need permission to photograph someone
You do not need permission to photograph a stranger in public. However, you do need permission if you want to use that photo in a way that suggests the person endorses something or benefits from it. This is called the right of publicity, and it protects people from having their image used to sell products, services, or ideas without their consent.
The rule is practical: if you photograph someone on a public street and post it on social media as a personal memory, that is fine. If you use that same photo in an advertisement for a weight-loss product, a dating app, or a political campaign, you need written permission from the person in the photo. The person does not have to be famous for this rule to explore — it protects everyone equally.
Editorial use — publishing a photo in a news article, a documentary, or a historical record — usually does not require permission, even if the photo is used to illustrate a story about that person. But commercial use — selling the photo, using it in an ad, or using it to promote a business — almost always does. The line between editorial and commercial can be blurry, so when in doubt, ask.
Photography in private spaces and places with privacy expectations
Photographing someone in a bathroom, changing room, shower, bedroom, or any space where they expect privacy is illegal in all states. This includes taking photos through windows, under doors, or with hidden cameras. The crime is sometimes called voyeurism or invasion of privacy, and it can result in criminal charges, jail time, and being added to a sex offender registry.
The same rule applies to medical offices, therapy sessions, and other confidential settings. Even if you own the building, you cannot photograph someone in a private space where they have a reasonable expectation of privacy without their knowledge and consent. Hospitals, doctors' offices, and mental health clinics have their own rules about photography, and most prohibit it entirely to protect patient privacy.
Private businesses can also set their own photography rules. A restaurant, store, gym, or office building can post a sign saying "no photography" or "no photos without permission," and you must follow that rule or leave. If you refuse to leave after being asked, you can be arrested for trespassing.
Recording audio and video together
Recording video in public is legal in all states, but recording audio — someone's voice or a conversation — has different rules depending on where you live. Some states are one-party consent states, meaning you can record a conversation if you are part of it, even if the other person does not know. Other states are two-party consent states, meaning everyone in the conversation must agree to be recorded.
If you are filming video in public and audio is captured as part of that video, the same rule applies. In a one-party consent state, you can film and record audio without telling people. In a two-party consent state, you need permission from everyone whose voice will be recorded. Two-party consent states include California, Florida, Illinois, Maryland, Massachusetts, Michigan, Montana, New Hampshire, Pennsylvania, and Washington, though this list can change.
The safest approach is to assume you need permission before recording anyone's voice, even in public. If someone asks you to stop recording, stop. If you continue after being asked to stop, you may face legal trouble even in a one-party consent state.
What to do if someone tells you to stop photographing
If you are on public property and someone tells you to stop photographing, you have the right to continue — but the situation matters. If it is a private citizen, they cannot force you to stop or delete photos. If it is a police officer, you must obey their lawful orders, though an order to delete photos or hand over your camera is usually not lawful unless they have a warrant.
If a business owner or security guard tells you to stop photographing on their property, you must leave when asked. If you refuse, you are trespassing and can be arrested. If you are on public property — a sidewalk, a park, a public street — and someone tells you to stop, you can politely decline and continue photographing. If they call police, officers may ask you to move or leave the area for safety or traffic reasons, but they cannot arrest you straightforward for taking photos from a public place.
If police detain you and ask for your camera or phone, you can ask if they have a warrant. Without a warrant, you do not have to hand over your device. You can say, "I do not consent to a search of my phone or camera." If they search anyway, that search may later be ruled illegal, which could help you in court. Write down the officer's name and badge number, and contact a lawyer if you are arrested.
Photographing children and minors
Photographing children in public spaces is legal, but using their image commercially requires parental permission. If you are a teacher, coach, or youth worker and want to photograph children for a school or organization newsletter, you typically need written permission from a parent or guardian first. Most schools and youth organizations have permission forms for this reason.
If you are a stranger photographing other people's children in public — at a park, a beach, or a playground — the legal right to do so exists, but it often creates conflict. Many parents feel uncomfortable with strangers photographing their children, and some will ask you to stop or call police. While you have the legal right to photograph in public, respecting people's concerns about their children's safety is a practical choice that avoids confrontation.
Frequently Asked Questions
Can a police officer make me delete photos I took in public?
No. Police cannot force you to delete photos or videos taken from a public place without a warrant signed by a judge. If an officer asks for your phone or camera, you can refuse and ask if they have a warrant. If they search without one, that search may be illegal and could help you later in court.
Do I need permission to photograph someone's house from the street?
Yes, you can photograph a house from a public street or sidewalk. You do not need permission to take the photo. However, if you want to use that photo to advertise real estate services, sell it, or publish it in a way that suggests the owner endorses something, you should ask permission first to avoid legal trouble.
What happens if I photograph someone and they demand I delete it?
If you took the photo in a public place, you are not legally required to delete it. However, if you used it commercially without permission or if the person was in a private space, they may have a legal claim against you. If someone asks you to delete a photo, consider whether keeping it is worth the potential conflict or legal cost.
Can I photograph someone through a window if they are inside a building?
If the person is visible through a window and you are standing in a public place, you can legally take the photo. However, if you are photographing someone in a private space where they expect privacy — a bedroom, bathroom, or medical office — that is illegal even if you are outside the building. The key is whether the person had a reasonable expectation of privacy.
Do I need a permit to photograph in a public park?
For personal use, no. For commercial photography — a paid photo shoot, advertising, or a film production — most parks require a permit. Contact your city or county parks department to ask about their rules. Permits usually cost money and may require liability insurance, but they allow you to set up equipment and control the space.
