Coordinate system Update:Notably, this dataset will be provided in NAD 83 Connecticut State Plane (2011) (EPSG 2234) projection, instead of WGS 1984 Web Mercator Auxiliary Sphere (EPSG 3857) which is the coordinate system of the 2023 dataset and will remain in Connecticut State Plane moving forward.Ownership Suppression and Data Access: 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 "Current Owner," the co-owner’s name will be listed as "Current Co-Owner," 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 "Suppression" field in the submission to verify specific details. This measure was implemented this year to help verify compliance with Suppression. New Data Fields: The new dataset introduces the "Land Acres" 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 FIPS code field, which provides the Federal Information Processing Standards (FIPS) code for each parcel’s corresponding block. This allows users to easily identify which block the parcel is in.Updated Service URL: 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.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.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. 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.CAMA Notes:The CAMA underwent several steps to standardize and consolidate the information. Python scripts were used to concatenate fields and create a unique identifier for each entry. The resulting dataset contains 1,353,595 entries and information on property assessments and other relevant attributes.<ul><li>CAMA was provided by the towns.</li></ul>Spatial Data Notes:Data processing involved merging the parcels from different municipalities using ArcGIS Pro and Python. The resulting dataset contains 1,290,196 parcels.<ul><li>No alteration has been made to the spatial geometry of the data.</li><li>Fields that are associated with CAMA data were provided by towns.</li><li>The data fields that have information from the CAMA were sourced from the towns’ CAMA data.</li><li>If no field for the parcels was provided for linking back to the CAMA by the town a new field within the original data was selected if it had a match rate above 50%, that joined back to the CAMA.</li><li>Linking fields were renamed to "Link".</li><li>All linking fields had a census town code added to the beginning of the value to create a unique identifier per town.</li><li>Any field that was not town name, Location, Editor, Edit Date, or a field associated back to the CAMA, was not used in the creation of this Dataset.</li><li>Only the fields related to town name, location, editor, edit date, and link fields associated with the towns’ CAMA were included in the creation of this dataset. Any other field provided in the original data was deleted or not used.</li><li>Field names for town (Muni, Municipality) were renamed to "Town Name".</li></ul>The attributes included in the data: <ul><li>Town Name </li><li>Owner</li><li>Co-Owner</li><li>Link</li><li>Editor</li><li>Edit Date</li><li>Collection year – year the parcels were submitted</li><li>Location</li><li>Mailing Address</li><li>Mailing City</li><li>Mailing State</li><li>Assessed Total</li><li>Assessed Land</li><li>Assessed Building</li><li>Pre-Year Assessed Total </li><li>Appraised Land</li><li>Appraised Building</li><li>Appraised Outbuilding</li><li>Condition</li><li>Model</li><li>Valuation</li><li>Zone</li><li>State Use</li><li>State Use Description</li><li>Land Acre </li><li>Living Area</li><li>Effective Area</li><li>Total rooms</li><li>Number of bedrooms</li><li>Number of Baths</li><li>Number of Half-Baths</li><li>Sale Price</li><li>Sale Date</li><li>Qualified</li><li>Occupancy</li><li>Prior Sale Price</li><li>Prior Sale Date</li><li>Prior Book and Page</li><li>Planning Region</li><li>FIPS Code </li></ul>*Please note that not all parcels have a link to a CAMA entry.*If any discrepancies are discovered within the data, whether pertaining to geographical inaccuracies or attribute inaccuracy, please directly contact the respective municipalities to request any necessary amendmentsAdditional information about the specifics of data availability and compliance will be coming soon.If you need a WFS service for use in specific applications : <a href='https://dservices3.arcgis.com/3FL1kr7L4LvwA2Kb/arcgis/services/Connecticut_CAMA_and_Parcel_Layer/WFSServer?service=wfs&request=getcapabilities' style='font-family:"Avenir Next", Avenir, "Helvetica Neue", Helvetica, Arial, sans-serif; font-size:15px;' target='_blank' rel='nofollow ugc noopener noreferrer'>Please Click Here</a>
