Municipal Parcel Files
Update: 2022 parcels and CAMA files are available by contacting the State GIS Office at firstname.lastname@example.org.
Connecticut's Regional Councils of Governments (COGs) collect digital parcel files and standardized property assessment data (CAMA) from each of their member municipalities by May 1st annually, pursuant to Section 7-100l of the Connecticut General Statutes. Through the voluntary cooperation of the COGs, OPM obtains copies of these datasets and makes them available for public download.
Data received from the COGs are compressed into .zip files by planning region and can be downloaded via the links below. OPM does not modify any of the parcel data files received from the COGs. The spatial accuracy and completeness of the data can vary by COG and by municipality. It is expected that municipal parcel files conform to Level 1 or higher of the Cadastral Data Standard.
For the most recent parcel and assessment data, contact the COG or municipality directly.
Guidance for municipalities and COGs to comply with CGS Sec. 7-100l is available.
