Revaluation Information

The Town of Durham selected Tyler Technologies, Inc. to assist with the town-wide revaluation project. Tyler Technologies is the oldest and largest provider of revaluation services and has performed revaluation nationally since 1938.

The major phases of a municipal revaluation are: 

Data Collection:

In July, Data Mailers were mailed to all residential properties. Data Mailers allowed property owners to verify the information the Town has on record.

Market Analysis, Valuation & Field Review:

Market analysis and valuation begins, followed by field review of properties to check and re-check values to ensure uniformity and accuracy of information.

Informal Hearings:

A Notice of Assessment Change is mailed to each property owner. After that, informal hearings allow anyone with questions concerning the revaluation process to speak with a staff member of Tyler Technologies, Inc. to discuss their property value.

Homeowners should review their assessment online by visiting the 2020 Revaluation List.

Assessments represent 70% of the October 1, 2020 market value, unless properties are classified in whole or in part under P.A. 490 farm, forest, or open space. Farm, forest, and open space assessments are reflected in the new assessment. Those values, however, are recommended by the State of Connecticut in tandem with the Agricultural Commission. 
Assessment exemptions (i.e. – Veteran’s exemptions) are not reflected in the new assessments shown on the Notice of Assessment Change but will be applied to the final assessments.

Hearings will be held over the phone by appointment only beginning February 1st and ending February 10th. Please schedule your appointment by February 5th by calling Tyler Technologies toll free at 1-800-273-8605 or scheduling online at and follow the instructions. You will need the Parcel Number listed on your Notice of Assessment Change when scheduling. If you have more than two parcels you wish to discuss, please do not schedule online, but instead call.

If you wish to appeal your assessment after the informal hearing process is complete, you must file a written appeal to the Durham Board of Assessment Appeals on or before March 20, 2021. Applications are available online at the Board of Assessment Appeals page.

If a property owner disagrees with the decision of the Board of Assessment Appeals, he/she must make application to Superior Court within two months of the Board of Assessment Appeals’ decision letter.
