Information We Collect

St Louis County collects specific facts to ensure accurate real estate valuations and tax assessments for the local community. These details help the assessor determine the fair market value of land and buildings located within the county borders. Every piece of data resides in secure servers managed by the county technology department to prevent leaks or breaches. We gather these facts through legal filings, site visits, and direct interactions with homeowners or business owners in Missouri. The law requires us to maintain these records to support the public tax roll and ensure fair funding for schools and roads. Our office tracks physical traits of houses, such as square footage, bedroom counts, and bathroom totals, to create fair models. We also record ownership history, sale prices, and deed transfer dates that arrive from the Recorder of Deeds office. These records form the backbone of the local tax system and allow for clear tracking of land ownership over many years. Our team updates these records during the biennial reassessment cycles that happen in odd-numbered years like 2024 and 2026.

Data You Provide Voluntarily

Homeowners often give us facts directly when they file for tax exemptions or appeal their property values. When you fill out a residential personal property declaration form, you share details about your vehicles and home assets. You might also submit contact details like phone numbers and email addresses when signing up for digital tax notifications or news. If you file an appeal with the Board of Equalization, you supply evidence such as photos or recent home appraisals. These files help us understand the specific condition of your house compared to others in the same Clayton or Kirkwood neighborhood. We use this data only to resolve your specific request or to update your account details for better communication. Our staff handles these paper and digital forms with care to keep your contact facts from reaching the public. We store your social security numbers or private phone numbers in protected fields that do not appear on public search tools. You have the right to know which facts we store and how those details influence your yearly tax bill in St Louis County.

Automatically Collected Information

Our website gathers technical data every time a user visits the online property search tool or the GIS map. This data includes your internet protocol address, the type of web browser you use, and the specific pages you view. We use cookies to remember your search settings and to help the map load faster during your next visit to the site. These digital logs help our tech team monitor for cyber threats and ensure the website stays online for everyone. We do not link your internet address to your name or physical home address during these standard browsing sessions. The system tracks which neighborhoods receive the most search traffic to help us allocate server resources during peak tax seasons. Automatic logs also record the date and time of every search to prevent bots from stealing mass amounts of data. This protection keeps the public database running smoothly for actual residents and real estate professionals who need accurate facts. We keep these server logs for a limited time before the system purges them to maintain user anonymity and privacy.

How We Use Your Information

The St Louis County Assessor uses the data collected to fulfill legal duties defined by Missouri State Statutes. Our primary goal involves placing a fair value on every piece of real estate in the county for tax purposes. We use sale prices from local markets to compare similar homes and ensure no one pays more than their fair share. These facts allow us to create a balanced tax roll that funds vital services like police, fire, and public education. We also use your data to determine if you qualify for specific tax relief programs or senior citizen credits. Without accurate records, the county could not distribute the tax burden evenly across all residential and commercial zones. Our office uses data to track new construction and renovations that change the value of a specific plot of land. We also use contact facts to alert you if there is a problem with your filing or a change in your status. Keeping your data accurate helps us serve you better and reduces the need for long phone calls or office visits.

For Service Improvements

We analyze how users interact with our online portal to make the search experience better for everyone in the county. If many people struggle to find a specific form, we move that link to a more visible spot on the homepage. User feedback helps us fix bugs in the GIS map so that parcel boundaries display correctly on mobile devices. We use data trends to decide when to hire more staff for the phone lines or the front desk. During high-traffic months like June and July, we use past data to prepare for the surge in valuation appeals. Improving our digital tools reduces the cost of government and saves taxpayers time when they need fast facts. We look at which devices residents use to visit our site so we can support older computers and new smartphones alike. Every update to our software comes from looking at how the public uses our existing tools to find property data. We want the St Louis County property appraiser website to be the most helpful resource for local real estate facts.

Communication & Notifications

Your contact details allow us to send important alerts regarding your property taxes and assessment deadlines. We send postcards and letters to your mailing address to notify you of changes in your home value. If you sign up for email alerts, we can give you instant updates about new laws or tax relief programs. These communications help you avoid late fees and ensure you have time to appeal if you disagree with our findings. We use your phone number to call you if a field appraiser needs to visit your property for a physical check. Direct communication prevents misunderstandings and helps us correct errors in our records quickly and efficiently. We do not use your email or phone number for marketing or share it with outside sales companies for any reason. Our office values your time and only sends notices that are required by law or requested by you. Staying connected helps maintain a transparent relationship between the county government and the people we serve in Missouri.

Legal and Compliance Purposes

Missouri law mandates that most property records remain open for public viewing to ensure government transparency and fairness. The Missouri Sunshine Law (Chapter 610 RSMo) dictates how we must share data with those who request it. We follow these laws to the letter to protect the integrity of the public record while shielding truly private facts. Some data must stay hidden, such as the banking details of individuals who pay their taxes through our online portal. We also comply with court orders that might require us to keep certain records confidential for safety reasons. Our legal team reviews every data request to make sure it follows state and local privacy rules. We keep audit trails of who accesses sensitive records to prevent internal misuse of data by county employees. Following these strict legal paths ensures that our office stays accountable to the voters and the legal system. Our commitment to compliance protects the county from legal risks and keeps your records secure according to the latest standards.

1. Verify legal ownership of all land parcels.
2. Calculate tax liabilities based on current market values.
3. Identify properties eligible for exemptions or credits.
4. Maintain history of land transfers and deed changes.
5. Notify owners of reassessment results every two years.

Data Protection and Security Measures

Protecting your personal data requires a multi-layered approach involving modern software and physical barriers at our Clayton office. We spend significant resources on cybersecurity to stop hackers from accessing the county database or GIS systems. Our tech team updates the firewalls and antivirus programs every day to block the latest digital threats from the web. We also use secure hardware to store all property files, ensuring that even a physical theft would not expose your data. Staff members undergo regular training on how to spot phishing emails and keep their passwords strong and unique. We limit the number of people who can edit property records to prevent accidental errors or intentional tampering. Only background-checked employees with a clear need to know can see private contact details or internal appraisal notes. These security steps create a safe environment for your real estate data and personal facts in St Louis County. We take our role as the keepers of your public records very seriously and work hard to earn your trust.

Encryption and Secure Access

Our website uses Secure Sockets Layer (SSL) technology to encrypt the data moving between your computer and our servers. This encryption makes it impossible for outside parties to read your search history or personal details as they travel. When you enter a parcel number or your last name, that data stays hidden from prying eyes on the internet. We also use advanced encryption for our internal databases where the most sensitive tax facts reside at rest. Accessing these systems requires multi-factor authentication for every county employee to ensure only the right people get in. We monitor for failed login attempts and block any suspicious activity coming from unknown locations or foreign countries. Our encryption standards meet or exceed the requirements set by federal and state data protection agencies for local governments. By using these strong tools, we prevent data theft and keep the St Louis County appraisal system safe for everyone. You can look for the padlock icon in your browser to confirm you are on our secure and verified portal.

Internal Access Restrictions

We use a strict permission system to control which employees can see different types of data within our local network. A clerk at the front desk might only see basic parcel facts, while a senior appraiser can see internal valuation models. This separation of duties ensures that no single person has too much power over the entire data system. We log every time an employee opens a sensitive file to create a clear record of who did what and when. If someone leaves their job at the county, we remove their access to all systems before they walk out the door. We also conduct regular audits of these permissions to ensure they still match the job duties of every staff member. Protecting data from the inside is just as important as blocking hackers from the outside world. These internal controls prevent the misuse of your private details and keep our office running with high integrity. We hold our staff to the highest ethical standards when they handle any data related to your home or business.

Additional Security Practices

Beyond digital locks, we use physical security to keep our servers and paper files safe from damage or theft. Our data center is located in a high-security building with restricted access and 24-hour video surveillance by county police. We use fire suppression systems and backup power units to prevent data loss during storms or hardware failures. Every night, we create off-site backups of the entire property database to ensure we can recover quickly from any disaster. We also use shredding services for any paper documents that contain sensitive facts that we no longer need to keep. Visitors to our physical office must check in and stay in public areas unless they have an escort from a staff member. We perform vulnerability scans on our network every month to find and fix any weak spots before they become problems. These layers of safety work together to create a solid shield for all the data managed by the St Louis County appraiser. Your records stay safe whether they are on a hard drive or stored in a physical file cabinet in Clayton.

• Daily database backups stored in separate physical locations.
• Monthly security audits of all network access points.
• Biometric or keycard access for all restricted server rooms.
• Mandatory cybersecurity training for all department staff.
• Automatic session timeouts on all public-facing search tools.

Opt-Out Preferences

Residents have certain choices when it comes to how their data appears on our public search tools and GIS maps. While the law requires most property facts to be public, we offer ways to shield specific sensitive details from general view. You can choose to opt-out of certain digital notifications if you prefer to receive all your tax mail via the US Postal Service. Some people prefer to have their names hidden from the online search results for safety or privacy reasons. We provide forms for law enforcement officers and judges who need their home addresses kept off the web for protection. You can also request that your phone number or email be removed from our digital contact list at any time. We respect your choices and will do our best to honor your preferences within the limits of Missouri state law. Understanding your options helps you take control of your digital footprint while still meeting your tax obligations. We want you to feel comfortable with the way the St Louis County Assessor handles your private and public data.

How to Limit the Use of Your Data

To limit how the county uses your data, you can start by only providing the facts that are legally required for your filing. You can also visit our Clayton office to fill out a privacy request form if you belong to a protected group under Missouri law. For example, participants in the Safe at Home program can have their records completely shielded from public view to prevent stalkers from finding them. If you want to stop receiving certain mailings, you can update your preferences through our online portal or by calling our help desk. We also allow you to opt-out of our browser-based tracking by adjusting the settings in your own web browser. Limiting the data you share reduces the risk of that data being used in ways you do not like. Keep in mind that some data, like your parcel value and tax status, must remain public so that the system stays fair. We balance your need for privacy with the public’s right to know how tax dollars are assessed and collected in the county. Contact us if you have questions about which details can be hidden and which must stay visible.

Sharing & Third-Party Services

We do not sell your property data to private companies, marketers, or data brokers for any reason. However, we do share data with other government agencies and trusted partners to provide the services you need. For example, we send data to the St Louis County Collector of Revenue so they can create and mail your tax bills. We also share valuation facts with the Missouri State Tax Commission to ensure our office follows state standards for accuracy. Some of our online tools are hosted by third-party tech companies that help us manage large sets of GIS mapping data. These partners must sign contracts that force them to follow our strict privacy rules and data protection standards. They cannot use your data for their own profit or share it with anyone else without our express permission. Sharing data between departments helps the county run more efficiently and ensures that your records stay consistent across all local agencies. We only share the facts that are needed for each specific task to keep your data exposure as low as possible.

When and Why We Share Information

Data sharing often happens during the tax cycle to ensure that schools, parks, and libraries receive their fair share of funding. We share parcel values with the local school districts so they can plan their budgets for the upcoming academic year. If you apply for a building permit, the public works department shares that data with us so we can update your home records. We also share data with the courts if a legal dispute arises over a property line or a tax assessment. During a natural disaster, we might share data with emergency responders to help them identify which homes were hit hardest by a storm. We also provide data to the Census Bureau and other federal agencies for regional planning and grant applications. Every instance of sharing serves a specific public purpose that benefits the residents of St Louis County as a whole. We track these data transfers to ensure they remain secure and follow all privacy laws. Transparency in sharing helps build a better community and a more effective local government for everyone in Missouri.

Third-Party Tools and Services

Our office uses several software tools to help manage the complex GIS maps and the massive database of over 400,000 parcels. These tools include mapping software from companies like Esri and cloud storage from providers like Microsoft or Amazon. These companies provide the high-tech infrastructure needed to keep our site fast and reliable during the busy tax season. We choose our partners based on their ability to keep data safe and their history of following government security rules. They do not have the right to look at your personal details unless they are fixing a technical problem with the system. We use standard contracts that protect the county and its residents from any data misuse by these outside firms. If a third party fails to meet our security needs, we end the partnership and find a new provider who can keep our data safe. Using these tools allows us to offer advanced features like 3D maps and historical aerial photos that would be too expensive to build alone. We ensure that these modern features do not come at the cost of your privacy or data security.

Your Rights & Data Control Options

As a property owner in St Louis County, you have the right to view, verify, and correct any data we have on file. Transparency is a core value of our office, and we want you to see exactly how we arrived at your home valuation. You can access your records online at any time or visit our office to see the physical files linked to your land. If you find a mistake, such as an incorrect bedroom count or the wrong square footage, you have the right to ask for a fix. We also give you the right to appeal your property value if you believe the market data we used is not accurate. You can present your own evidence to the Board of Equalization to show why your tax bill should be lower. We also protect your right to stay informed by sending notices before we make big changes to your records. Knowing your rights helps you interact with the county government with confidence and ensures you are treated fairly. Our staff is here to help you exercise these rights and navigate the local tax system with ease.

Requesting Data Access or Deletion

You can request a copy of all the data we hold regarding your property by filing a formal request under the Missouri Sunshine Law. Most of these records are available for free through our online search portal, which stays open 24 hours a day. If you need a certified copy of a record for a bank or a court case, you can visit our Clayton office during business hours. Please note that we cannot delete property records that are required by law to be part of the public tax roll. However, we can delete or update contact details like your email address or phone number if you no longer want them in our system. To request a change or deletion, you can send a written letter to the Assessor or use our online contact form. We will process your request as fast as possible, usually within three business days as required by state law. Keeping your records clean and accurate is a goal we both share, and we welcome your input on your files. We do not charge a fee for standard data access via our website, making it easy for you to check your records at any time.

Updating Your Personal Information

It is important to keep your mailing address and contact facts up to date so you never miss a tax notice or a refund check. If you move or change your name, you should notify the Assessor’s office and the Recorder of Deeds as soon as possible. You can update your mailing address by filling out a simple change-of-address form on our website. This ensures that your next tax bill goes to the right place and prevents late fees caused by missed mail. We also encourage you to update your contact details if you want to participate in our digital notification programs. Keeping your records current helps us avoid errors and ensures that the tax burden is placed on the correct person. If you notice an error in your parcel’s physical traits, please contact us so we can send an appraiser to verify the facts. We want our database to be as accurate as possible for the benefit of all county residents and businesses. Updating your data is a fast and easy process that protects your property rights and your wallet.
