Most people assume that if something feels harmless, it’s probably legal. But across the U.S., there are plenty of surprising state laws that restrict everyday activities. Whether these rules were created for public safety, historical reasons, or simply outdated logic, they’re still enforceable. From collecting rainwater to selling cookies from your kitchen, these strange state-specific rules can catch you off guard. It’s always a good idea to double-check local laws before you dive into a side hustle or quirky habit. Let’s explore nine things you might not realize are illegal, depending on where you live.
1. Selling Homemade Baked Goods Without a Permit
If you’re thinking about starting a small baking business from your home kitchen, be aware that many states have strict cottage food laws. In some places, such as New Jersey, selling homemade goods like cookies or bread without a specific permit is illegal. Even states that allow it typically require food safety training or limit sales to farmers’ markets. These laws aim to protect public health, but they can be confusing for hobby bakers. Before you turn your oven into a business tool, make sure you know your local health regulations to avoid fines or shutdowns.
2. Collecting Rainwater on Your Property
Though it might seem eco-friendly, collecting rainwater isn’t always allowed. In some states like Colorado, rainwater harvesting was restricted for years due to water rights laws. While laws have eased recently, they still limit how much you can collect and for what purposes. These laws date back to the idea that all water eventually flows into shared rivers or reservoirs and should be accounted for. Other states are more lenient, even encouraging rain collection. If you’re setting up barrels on your property, check your state laws to make sure you’re not violating any water usage rules.
3. Walking Barefoot in Public Buildings
It may sound silly, but in some states and municipalities, it’s illegal to walk barefoot in certain public places like restaurants, libraries, or government offices. These rules often stem from outdated health codes or safety concerns about stepping on sharp objects. While not always strictly enforced, you can still be asked to leave or denied entry. Some localities even have signage to remind visitors of footwear requirements. If you’re someone who enjoys going shoeless, keep a pair of flip-flops handy when entering public spaces to avoid awkward confrontations.
4. Driving With an Obstruction on the Windshield
You might think it’s harmless to hang an air freshener or graduation tassel from your rearview mirror, but in several states, that’s technically illegal. States like California and Minnesota have laws that prohibit any object that obstructs the driver’s view. Even small decorations can be cited if a police officer believes they interfere with road safety. Enforcement can vary depending on the officer and the state, but it’s best to keep your windshield completely clear. That fuzzy dice might be nostalgic, but it could cost you a ticket if you’re not careful.
5. Holding a Garage Sale Without a Permit
Hosting a yard or garage sale seems like an innocent weekend activity, but many cities require a permit to do so. This is especially true in urban areas or homeowner associations where frequent sales could disturb neighbors or attract unwanted traffic. Some places limit the number of garage sales you can host per year. Without a permit, you might face a fine or be forced to shut down early. Before advertising your next big decluttering event, check with your city or county to make sure you’re following all local requirements.
6. Using Fake Names Online
Creating a fake name on social media or email might seem harmless, but in some states, this can run afoul of impersonation or fraud laws. For example, using someone else’s identity or pretending to be a public figure can be considered illegal even if done jokingly. While most states focus on intent to deceive or harm, a few have broader interpretations. It’s especially risky if that identity is used to harass or manipulate others. If you’re online for fun, it’s safer to use pseudonyms that clearly aren’t meant to impersonate someone real.
7. Letting Your Car Idle for Too Long
In cold or hot weather, it’s common to let your car idle while you warm it up or cool it down. But in several states and cities, this practice is regulated or outright banned. Places like New York City and Pennsylvania have anti-idling laws to reduce air pollution. Some states impose time limits, often just a few minutes, and can issue fines for violations. Even if you’re just running back inside for a second, leaving your car idling could land you in legal trouble. It’s better to turn off the engine unless you’re actively driving.
8. Sharing Netflix Passwords
Sharing your Netflix or other streaming service passwords might seem generous, but in some states, it’s considered illegal under computer crime or theft of services laws. Tennessee, for example, passed a law in 2011 specifically targeting unauthorized sharing of subscription passwords. The idea is that these accounts are meant for personal use, and sharing access can be seen as a form of piracy. While enforcement is rare, especially for casual use among family members, it’s technically a legal risk if you’re sharing accounts with people outside your household.
9. Reusing the American Flag for Apparel or Décor
Many people enjoy showing patriotism by wearing flag-themed clothing or using the American flag in decorations, but this can violate flag code laws in some states. The U.S. Flag Code discourages the use of the flag for advertising or apparel, and while it’s not strictly enforced as a criminal matter, some states have local ordinances that treat it more seriously. Misusing the flag could lead to citations or public backlash. If you want to show your national pride, consider more respectful displays like properly flying a flag at your home.
