Overview
The Home Improvement exemption is an eight-year decreasing exemption on permitted alterations, reconstruction, and improvements which increase the assessed value of a one or two family home. The exemption provides property tax relief from the increase in equalized market value, between $3,000 and $80,000, caused by the improvement. Additional buildings and yard improvements do not qualify for this exemption. The home improvement project must be fully assessed before an exemption is granted. In the first year, 100% of the assessed value of the improvement/new construction is exempt. In the second year, 87.5%; in the third year 75%, and so on.
