If we see someone breaking the rules, we may block their IP address. We do this to protect the servers and the private data of property owners.

Intellectual Property Rights

All the data, maps, and text on this site belong to St Louis County. This includes the code that makes the site work and the way data looks. You do not own any part of the data just because you can see it on your screen. The county spent a lot of money to create these records and maps. We protect our work using copyright and trademark laws. You may not copy the design of the site or use our logos without asking first. Intellectual property rights help the county keep control over the quality of the data. If people could take the data and change it, it would cause big problems for the public. We keep the rights to the “St Louis County Assessor” name and all related marks.

Ownership of Content

The St Louis County Assessor Office owns the property records and tax assessments. We also own the GIS maps and the photos of houses and buildings. No one else has the right to say they own this data. Even if you pay property taxes, the data records belong to the county government. This ownership includes the metadata and the history of the property values. We keep these records safe in our digital vault. You are allowed to look at them, but you do not own the files. The data is a public record, but the way we organize it is our intellectual property. We take this ownership seriously to prevent data fraud in the real estate market.

Use of Website Materials

You can print one copy of a property report for your own use. You can save a PDF of your tax bill to your home computer. These materials are for your personal knowledge or for legal property tasks. You can show the data to your bank or a person buying your house. But you cannot use these materials to build your own website. You cannot put the county maps on a site where you charge people money. Use the materials in a way that respects the hard work of the county staff. If you need to use a lot of data, you must ask for permission in writing. Most small tasks do not need a special permit if you follow these basic rules.

Restrictions on Republishing

You are not allowed to republish the whole database on the internet. Do not copy lists of names and addresses to put in a book or on a blog. This stops people from getting spam or unwanted visitors. You cannot use software to crawl the site and pull out thousands of records. This is called data mining, and we forbid it. If you republish a small part of the data, you must not change the facts. You cannot make a property look like it has a lower tax value than it really does. Republishing data in a way that tricks people is a crime. We will take legal steps if we find our data used in a scam or on a fake real estate site.

Attribution Requirements

When you use data from this site, you must say where it came from. You should write “Source: St Louis County Assessor Office” on your document. This tells people that the data is official. It also helps people find the source if they have questions. Proper attribution is part of being a good user of public data. Do not act like you gathered the data yourself. Give credit to the county employees who do the work. If you use a map, keep the county seal visible on the image. This proves the map is a real government record. Following these steps helps keep property records honest across the community.

Limitation of Liability & Disclaimers

The county provides this property data as a public service. We do not promise that every single piece of data is perfect. Real estate facts change every day because of sales and new buildings. The St Louis County property appraiser terms and conditions say we are not liable for errors. If you buy a house based on a mistake on this site, we are not responsible. You should always check the physical deeds at the Recorder of Deeds office. Our data is for “informational use” and is not a legal substitute for a title search. We offer the data “as is” and “as available.” This means we do not guarantee the site will be up 20 hours a day or that it will be fast.

No Warranty on Accuracy or Completeness

We do not give a warranty that the data is 100% right. Sometimes a house might have the wrong square footage listed. Sometimes an owner’s name might have a typo. We work hard to fix these things, but we do not promise a perfect database. The data reflects what we knew at the time of the last assessment. Because property values change, the data on your screen might be old. You should not use this data for a legal court case without getting a certified copy. A certified copy is a paper document signed by the Assessor. The digital data on the website is not a certified legal record. Use it as a starting point, but do not stop there if the stakes are high.

Use at Your Own Risk

You take all the risk when you use the data on this site. If the data causes you to lose money, the county will not pay you back. This is a standard rule for government websites. We provide the tools, but you decide how to use them. If you see a house listed for $200,000 and it is really $300,000, that is an error you must verify. Do not make big life choices based only on a website search. Talk to a lawyer or a real estate pro before you sign any contracts. The county is not your financial advisor. We are a government office that collects taxes and tracks property values. By using this site, you agree that you are responsible for your own choices.

Errors, Omissions & Outdated Information

Errors happen in every large database. St Louis County has hundreds of thousands of parcels. We might miss a new deck or a garage on a house. We might list a property as a commercial lot when it is now a park. These omissions are not on purpose. We fix them as we find them during our field visits. Outdated data is also common because deeds take time to process. If a house sells today, the website might not show the new owner for weeks. The tax year runs on a specific schedule in Missouri. What you see might be the value from last year. Always check the “Tax Year” label on the screen to see how old the facts are.

External Links Disclaimer

Our site might have links to other websites like the State of Missouri or the IRS. We do not control those other sites. If you click a link and leave our site, our rules no longer apply. We are not responsible for the facts or the safety of those other pages. A link does not mean we support everything on that other site. We provide links to help you find more help with your taxes. If a link is broken, you can tell us, but we do not have to fix it. Always look at the URL in your browser to see where you are. Stay safe by only giving your private data to sites you trust. The county will never ask for your social security number on a public search page.

User Accounts & Security

Some people need special access to get more data from the Assessor. Real estate pros or title companies might have user accounts. These accounts have extra rules to keep the data safe. If you have an account, you are the only one who should use it. Do not share your login with your friends or other workers. Each account is for one person only. We track who logs in and what they look at. This helps us stop people from stealing large amounts of data. If we see weird activity on your account, we will lock it. You will have to call the office to get it open again. Security is the most vital part of our digital records system.

Account Responsibility

You are the boss of your own account. If someone else uses your account to break the rules, you get the blame. This is why you must pick a strong password. Do not use “password123” or your birthday. Pick something hard to guess. If you leave your job, you must tell us to close the account. Do not let the person who takes your job use your old login. We want to know exactly who is looking at our data. This keeps the system clean and safe for the public. If you lose your account access, we can help you reset it. But we will ask you questions to prove you are who you say you are.

Protecting Your Login Credentials

Keep your username and password in a safe place. Do not write them on a sticky note and put it on your monitor. If you use a public computer, always log out when you are done. If you stay logged in, the next person can see your history. They might even change your settings. Use a password manager if you have many logins to track. Never send your password in an email to anyone, even to our office. We will never ask for your password in an email. If you get an email asking for it, it is a scam. Delete those emails and do not click any links inside them. Protecting your login is the best way to keep the county data safe.

Unauthorized Access Reporting

If you think someone stole your password, tell us right away. If you see data on the site that looks like it was hacked, call us. We need your help to keep the site working well. Reporting problems helps the whole community. We have a team that looks for hackers and bad bots. But sometimes a human sees the problem first. If you report a security hole, we will look at it fast. Do not try to fix the site yourself. Just tell us what you saw and where you saw it. We take every report seriously to make sure the St Louis County property appraiser terms and conditions stay strong. Your report could stop a big data leak.

Data Collection & Privacy

We care about your privacy when you use the St Louis County property search. We do not track your name or home address when you just look at public data. However, we do collect some technical data to make the site work. This is normal for all websites on the internet. We want to know which pages are popular and which ones are hard to find. This helps us spend tax money in the right way to fix the site. We do not sell your data to companies that want to show you ads. The data we collect stays with the county or our tech partners. Privacy is a right that we respect for every visitor.

Information We May Collect

When you visit, our server records your IP address. This is like a phone number for your computer. We also see what kind of browser you use, like Chrome or Safari. We see the date and time of your visit and the pages you looked at. If you search for a specific house, we record that search term. We do this to see what neighborhoods people are interested in. If you fill out a contact form, we collect your name and email. We only use that to answer your question. We do not keep a list of every person who looks at a specific house. Your secrets are safe with us as you do your research.

Use of Cookies & Analytics

We use cookies to make the site better. A cookie is a tiny file that sits on your computer. It helps the site remember your settings. For example, if you like the map zoomed in, a cookie can remember that. We also use analytics tools to see how many people visit us each day. This data is all grouped together. We do not look at one person’s data alone. We look at the “big picture” to see if the site is fast enough. You can turn off cookies in your browser settings if you want. The site will still work, but some parts might be slower. Cookies help us give you a better experience on the property appraiser site.

How We Handle Your Data

We keep the data we collect on secure servers. We follow Missouri state laws about how long we must keep records. Public records laws mean some of our emails might be open to the public. But your private search history is usually not a public record. We do not give your data to anyone unless the law says we have to. If a judge orders us to give up data, we must follow the law. Other than that, we keep your visit data quiet. We use firewalls and encryption to stop people from stealing the data. We update our security every year to stay ahead of bad actors on the web.

Refer to Our Privacy Policy for Full Details

These terms give you a quick look at privacy. But we have a full Privacy Policy that goes into more detail. You should read that policy if you have big worries about your data. It explains every rule the county follows for all its websites. The St Louis County property appraiser terms and conditions work with the Privacy Policys. Together, they create a safe place for you to get the facts you need. You can find a link to the full policy at the bottom of every page on the county site. Knowing your rights is the best way to use the internet. We want you to feel good about using our digital tools.

Governing Law & Dispute Resolution

The laws of the State of Missouri govern these terms. If there is a fight about these rules, a Missouri court will decide the winner. You agree that any legal case must happen in St Louis County. This is because the office and the properties are all located here. We do not use the laws of other states or countries. Missouri law is very clear about property taxes and public records. By using the site, you agree to follow these local laws. If a part of these terms is found to be wrong by a judge, the rest of the terms still stay in place. This protects the agreement from being destroyed by one small mistake.

Jurisdiction – State of Missouri

St Louis County is part of the State of Missouri. Every search you do on this site happens under Missouri’s legal power. The Missouri Revised Statutes (RSMo) Chapter 137 defines how we assess property. Chapter 138 defines how you can appeal your property value. These laws are the foundation of everything we do. If you live in another state, you still must follow Missouri law while on this site. You cannot sue us in a different state. You must bring your case to the local courts in Clayton, Missouri. This makes things fair because the records and the people are all here. The State of Missouri has the final say on all property data rules.

Legal Remedies and Arbitration

If you have a problem with the county, we want to talk first. Most problems can be fixed with a phone call or a meeting. If we cannot agree, we might use arbitration. This is a way to settle a fight without a big court trial. An independent person listens to both sides and makes a choice. This is often faster and cheaper than a law suit. However, the county keeps all its legal rights under state law. We do not give up our “sovereign immunity.” This is a legal rule that protects the government from some types of law suits. We will always try to be fair, but we must protect the taxpayers’ money too.

Waiver of Class Actions

By using this site, you agree to only bring a case as one person. You cannot join a “class action” suit against the county office. You cannot be the leader of a group of people suing us at once. Every property case is different because every house is different. This is why we handle things one by one. This rule helps keep legal costs down for everyone. It also means your specific problem gets the attention it needs. If you have a problem with your tax bill, you should use the official appeal steps. These steps are set by law and work better than a law suit. We want to fix errors fast and for each person directly.

Changes to Terms & Conditions

The St Louis County property appraiser terms and conditions are not set in stone. We modify them as the office grows and as the web changes. We might add new rules about using AI to look at our data. We might add rules about how maps can be used in apps. These changes help us stay current. We do not need a vote to change these rules. The Assessor has the power to set the rules for the office’s digital data. Every time you see a “last updated” date change, you should read the terms again. This ensures you are always following the current law and the current office policies.

Right to Modify Terms

We keep the right to change, add, or take away any part of these terms. We do this to protect the data and the public. Sometimes a new way to steal data is found, and we have to change the rules to stop it. Sometimes the state legislature passes a new law that changes our job. We will make those changes on this page as fast as we can. You do not have the right to demand that the rules stay the same. As a user of a free public service, you must adapt to the rules we set. We try to make changes that help the most people while keeping the data safe.

Notification of Changes

We do not send out emails when the terms change. We do not put it in the newspaper. The only place we post the changes is right here on this website. This is why you should look at this page once in a while. If a change is very big, we might put a small alert on the home page. But usually, the changes are small and just fix the language. You are responsible for knowing the rules. “I didn’t know the rules changed” is not a legal excuse. We keep the site open and the rules clear so everyone can see them easily. This transparency is part of our goal to be a trusted government office.

Your Responsibility to Stay Informed

Being an informed citizen means knowing the rules of your local government. When you search for St Louis County property data, you are using a public tool. You should know how that tool is allowed to be used. Staying informed protects you from making a mistake that could get you blocked from the site. It also helps you understand how your tax dollars are used to manage data. Read the terms once a year or every time you have a big property task. It only takes a few minutes but it can save you a lot of trouble. We want our users to be smart and follow the law at all times.

St Louis County Assessment Deadlines

To help you use the data better, you should know these key dates. These dates affect when the data on the site changes. In Missouri, property is valued as of January 1st every year. If you build a garage in June, it might not show up on the tax roll until the next year. Knowing these dates helps you understand why the website might look “outdated” sometimes. It is not an error; it is just how the law works. Use this table to plan your property searches and appeals.
