Defective Concrete and Crumbling Foundations Information Update

Mansfield is one of about twenty plus municipalities in Northeastern Connecticut known to have properties built using defective concrete in building foundations. Legislation has recently passed allowing owners of properties built in 1983 or later, who have been impacted by defective concrete, to receive a reduced property assessment. You must, however, have a licensed, professional engineer inspect your property and provide you with a written report indicating that your property has defective concrete.  A copy of the engineer’s report must be submitted to the Assessor’s Office, and the assessment staff must also inspect your property.  For more information about the process of receiving a reduced assessment, please contact our office by phone: (860)429-3311 or email:
