Navigating Maryland real estate records often starts with a single official database: the State Department of Assessments and Taxation portal. Whether you're a homebuyer checking tax histories, a real estate agent pulling parcel data, or a title researcher verifying ownership, understanding how to query this database saves hours of legwork.
The Maryland SDAT Real Property database is a public repository containing tax assessments, ownership histories, and property characteristics for millions of parcels across the state's counties and Baltimore City. While the interface is straightforward, knowing which search parameters to use and how to interpret assessment values prevents costly real estate mistakes.

The Maryland State Department of Assessments and Taxation maintains the public assessment records for every property in the state. The online Real Property Data Search tool allows anyone to look up real estate records free of charge.

How to Search the SDAT Database
Running an effective query requires choosing the right search criteria based on what information you currently have. The system lets you search by location and specific identifiers.
Searching by Location
If you know the physical address of the property, select the appropriate county or municipality first. Maryland has 23 counties and Baltimore City, each structured under distinct district codes. Enter the street number and street name. Keep abbreviations standard—use "St" instead of "Street" or "Rd" instead of "Road" to ensure the database engine retrieves an exact match.
Searching by Account Identifier
Every property in Maryland has a unique account number, typically organized by county code and parcel identifier. If you have a tax bill or a previous deed, the account number yields an instant, unambiguous match. This method avoids naming errors common with shared street names or multi-unit subdivisions.
Searching by Owner Name
You can search by individual or corporate owner name. Enter the last name followed by the first name for individuals, or the full corporate title for businesses. Because common names generate multiple results, cross-reference the property address or zip code to confirm you're viewing the correct parcel.
Interpreting Property Assessment Values
When you pull up a property record, you'll see several financial and physical figures. Understanding what these numbers mean prevents confusion during property evaluations.
The base value represents the state's assessment of what the land and structures are worth. Maryland reassesses properties on a triennial cycle—meaning every property is evaluated once every three years.
You'll also find the homestead tax credit eligibility status. Maryland caps how much a primary residence's taxable assessment can increase each year. If a home isn't registered as a primary residence, it won't qualify for this credit, which often explains why tax bills spike for rental or investment properties.
Common Pitfalls and Limitations
While the SDAT portal is powerful, it has specific limitations that catch researchers off guard.
- Timing lags: Recent property sales take time to process. If a home sold last week, the deed transfer might not appear in the database immediately.
- Mailing vs. physical addresses: The owner's address listed is often a mailing address where tax bills go, which may differ entirely from the physical property location.
- Zoning details: SDAT handles tax assessments and ownership, but it doesn't always provide detailed local zoning maps or code violation histories. For zoning rules, you must check municipal planning departments.
Frequently Asked Questions
Is the SDAT Real Property Search free?
Yes, the search tool provided by the Maryland Department of Assessments and Taxation is entirely free for public use. You don't need to create an account or pay subscription fees to look up basic property records.
How often are Maryland property assessments updated?
Properties are reassessed on a three-year cycle. The state divides properties into three groups so that approximately one-third of all properties are reassessed each year.
Why can't I find a newly built home in the database?
New construction requires subdivision approval, lot creation, and physical assessment before a new account number is generated. This administrative pipeline can take several months after construction finishes.
Can I find out who owns a commercial building through SDAT?
Yes. You can search by business entity name. If a commercial property is owned by an LLC or corporation, the record lists the registered corporate name and its principal address on file.
