Finding Your Property Information Online

These instructions will help you locate your property information on our real property data system. You can search the online database by either the address, street name, account identifier or map reference. You can not search by owner's name, town, neighborhood, subdivision or zip code.

To begin go to our home page www.dat.state.md.us  

1. select the Real Property Data Search link
2. Select the county in which to search


Searching by address

1. Do not use street directions (e.g. "North", "Southeast", "West", etc.) or any abbreviations of street directions.

2. Do not use street name suffixes (e.g. "Avenue", "Street", "Way", etc.) or any abbreviations of street name suffixes.

3. To perform a specific search on a street name, enter the complete name.  For example, a search on  "Preston", would only return records that had "Preston" as the name.   If you do not find the right property, perform a general search by truncating the street name followed by an asterisk(*).  This will return street names that match the truncated search.  For example, a search on "301 Pr*" would return 301 Preston Street, 301 President Street, 301 Pratt Street, etc.

4. If you are still not finding the property, try leaving off the street number. While this may result in several matches, it will give you an idea of whether or not you have the street name correct.  Also, the official street number assigned to the property by the local government may not be the same as the number the owner uses.


Using your assessment notice to search by account number

Your property account identification number is located above your name and address on your assessment notice. Look for the information in the following format:

     ACCT#
01 02 123456
         4         40500       0391 302000 C
     DOE, JOHN
     123 MAIN ST
     ANYTOWNIN, MD 21200-0000

In the above example, the property account indentification number (ACCT #) consists of the county code 01, the assessment district 02 and account number 123456. The county code identifies the jurisdiction in which the property resides.

Select the county in which the property is located by matching the county code to the respective name from the above County Codes table. The county name can also be identified by looking at SDAT's return address on the assessment notice. The return address will be the SDAT office for the county in which the property is located, for example, property located in Garrett County will have the following return address:

    State of Maryland
    Department of Assessments and Taxation

    GARRETT COUNTY
    PO BOX 388
