Connecticut CAMA and Parcel Layer 2024

Published by State of Connecticut | State of Connecticut | Metadata Last Checked: September 15, 2025 | Last Modified: 2025-09-12
<p><span style='font-size:inherit;'><strong>Coordinate system Update:</strong></span></p><p>Notably, this dataset will be provided in <strong>NAD 83 Connecticut State Plane  (2011) (EPSG 2234)</strong> projection, instead of <strong>WGS 1984 Web Mercator Auxiliary Sphere (EPSG 3857)</strong> which is the coordinate system of the 2023 dataset and will remain in Connecticut State Plane  moving forward.</p><p><b>Ownership Suppression and Data Access:</b><br />The updated dataset now includes parcel data for all towns across the state, with some towns featuring fully suppressed ownership information. In these instances, the owner’s name will be replaced with the label &quot;Current Owner,&quot; the co-owner’s name will be listed as &quot;Current Co-Owner,&quot; and the mailing address will appear as the property address itself. For towns with suppressed ownership data, users should be aware that there was no &quot;Suppression&quot; field in the submission to verify specific details. This measure was implemented this year to help verify compliance with Suppression.<br /></p><p><strong>New Data Fields:</strong><br />The new dataset introduces the &quot;<strong>Land Acres</strong>&quot; field, which will display the total acreage for each parcel. This additional field allows for more detailed analysis and better supports planning, zoning, and property valuation tasks. An important new addition is the <strong>FIPS code</strong> field, which provides the <strong>Federal Information Processing Standards (FIPS) code</strong> for each parcel’s corresponding block. This allows users to easily identify which block the parcel is in.</p><p><strong>Updated Service URL:</strong><br />The new parcel service URL includes all the updates mentioned above, such as the improved coordinate system, new data fields, and additional geospatial information. Users are strongly encouraged to transition to the new service as soon as possible to ensure that their workflows remain uninterrupted. The URL for this service will remain persistent moving forward. Once you have transitioned to the new service, the URL will remain constant, ensuring long term stability.</p><p>For a limited time, the old service will continue to be available, but it will eventually be retired. Users should plan to switch to the new service well before this cutoff to avoid any disruptions in data access.</p><p style='margin-top:0px; margin-bottom:1.5rem; font-family:&quot;Avenir Next W01&quot;, &quot;Avenir Next W00&quot;, &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, sans-serif; font-size:16px;'><span style='font-family:inherit;'>The dataset has combined the Parcels and Computer-Assisted Mass Appraisal (CAMA) data for 2024 into a single dataset. This dataset is designed to make it easier for stakeholders and the GIS community to use and access the information as a geospatial dataset. Included in this dataset are geometries for all 169 municipalities and attribution from the CAMA data for all but one municipality. Pursuant to Section 7-100l of the Connecticut General Statutes, each municipality is required to transmit a digital parcel file and an accompanying assessor’s database file (known as a CAMA report), to its respective regional council of governments (COG) by May 1 annually. </span></p><p style='margin-top:0px; margin-bottom:1.5rem; font-family:&quot;Avenir Next W01&quot;, &quot;Avenir Next W00&quot;, &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, sans-serif; font-size:16px;'><span style='font-family:inherit;'>These data were gathered from the CT municipalities by the COGs and then submitted to CT OPM. This dataset was created on 10/31/2024 from data collected in 2023-2024. Data was processed using Python scripts and ArcGIS Pro, ensuring standardization and integration of the data.</span></p><p style='margin-top:0px; margin-bottom:1.5rem; font-family:&quot;Avenir Next W01&quot;, &quot;Avenir Next W00&quot;, &quot;Avenir Next&quot;, Avenir, &quot;Helv
