Maryland Property Assessment Field Reference

Maryland Real Property Assessments: Fields Reference is a data dictionary supplementing the statewide property assessment dataset. It provides metadata for the main assessment data from the State Department of Assessments and Taxation and the Maryland Department of Planning. The reference was last updated in April 2024.

Use Cases

• Map raw data fields from the main assessment dataset to human-readable 'Field Name' values for reporting and dashboards.
• Identify the correct 'API Field Name' for programmatically querying the associated property assessment data via an API.
• Understand the correspondence between 'SDAT Field Number' and 'MDP Field Name' for cross-referencing data from two state agencies.
• Determine the 'Data Type' of each field in the main dataset to guide data cleaning and validation processes.

Strengths

• Provides a direct mapping between six distinct metadata attributes for property assessment fields.
• Serves as an official reference for a large statewide property dataset, ensuring authoritative field definitions.

Limitations

• The dataset contains only metadata; it does not include actual property values or assessment records.
• The number of rows (fields defined) and the temporal coverage of the reference itself are unknown.
