Connecticut Property Assessments and Parcel Data for 2024

169 Connecticut towns contributed property assessment data for a statewide 2024 collection effort. The GIS office compiled this information into a seamless parcel layer, cleaning inconsistencies from municipal submissions. This file was generated on September 28, 2024, from data collected throughout the year.

Use Cases

• Model property valuation using features like Land Acres, Stories, Number of Bedroom, and Bathrm Style Description.
• Analyze spatial property characteristics by joining CAMA data to parcel geometry via the link column in GIS software.
• Track assessment changes over time by comparing Pre Yr Assessed Total, Pre Yr Assessed Building, and Valuation Year fields.
• Study property ownership patterns using suppressed owner fields and location addresses like Street Name and Mailing Zip.

Strengths

• Statewide coverage includes data from all 169 Connecticut towns.
• Contains over 30 columns detailing property characteristics, assessments, and location.
• Data was cleaned and reorganized to align with a state schema after collection.

Limitations
