Calgary Property Assessments with Land Use and Construction Year

Calgary's assessed values for residential, non-residential, and farm land properties with registered parcels. The dataset includes columns for LAND_USE_DESIGNATION, ASSESSED_VALUE, YEAR_OF_CONSTRUCTION, and ADDRESS, and is updated annually by data.calgary.ca. Data for the current year is made available each January.

Use Cases

• Modeling ASSESSED_VALUE based on LAND_USE_DESIGNATION, LAND_SIZE_SM, and YEAR_OF_CONSTRUCTION using regression techniques.
• Analyzing spatial distribution of property values by joining ADDRESS or MULTIPOLYGON data with geographic boundaries.
• Tracking changes in RE_ASSESSED_VALUE and ASSESSMENT_CLASS over time using ROLL_YEAR for longitudinal studies.
• Segmenting property markets by analyzing correlations between PROPERTY_TYPE, COMM_NAME, and FL_ASSESSED_VALUE or NR_ASSESSED_VALUE.

Strengths

• Includes 22 columns covering assessment values, land use, construction year, and spatial identifiers.
• Annual update cycle provides a consistent temporal series, with data available from ROLL_YEAR 2020 onward.
• Geospatial data is present via the MULTIPOLYGON column, enabling map-based analysis.

Limitations

• Row count and total data size are unknown, which may limit suitability assessment for large-scale processing.
• Description metadata is limited; actual data quality requires manual inspection after download.
• The dataset excludes titled parking stalls, storage units, and linear property, limiting coverage of all assessable property types.
