Newington revaluation: townwide assessed values rise about 51%; interactive portal launched

Deputy Assessor Danielle Delino told the Newington Town Council on Nov. 25 that the town’s 2025 revaluation increased the grand-list market value by 51.39% overall and that residential parcels rose about 55.5% on average. "So what was our overall increase? 51.39%," Delino said during an illustrated presentation on the mass-appraisal process and performance metrics.

Delino said the revaluation followed standard mass-appraisal methods — sales-comparison, cost and income approaches — and met Connecticut performance-based testing standards. She reported a median assessment ratio of 67% (the statute’s target band is ±10% of a 70% ratio), a coefficient of dispersion of 5.88%, a price-related differential of about 1.00 and an unsold property test result near 1.05.

The assessor’s office also broke out changes by property type: condos rose about 64.8%, commercial parcels about 37.1% and vacant land about 14.0%. Delino said the 2024 median market value of $232,688 rose to about $343,600 in the 2025 grand list.

Monnique Michic demonstrated a new interactive revaluation data platform the town has published online. "We have developed the first interactive revaluation data platform for a municipality," Michic said, showing parcel-level search, comparison bars for old vs. new values, townwide data-insight dashboards and a valid-sales viewer covering October 1, 2023 to October 1, 2025.

Council members pressed staff on several issues: how Newington compares with nearby towns (staff said Newington tracks closely with similar communities), why condos jumped proportionally more (the sales market for condos has been especially strong), and whether higher appraisals necessarily mean higher tax bills (staff explained future mill-rate decisions during the budget process determine final bills and noted state limits and balancing factors).

Delino described outreach and next steps: informal hearings are underway (decision notices going out in early January), the grand list will be signed by Jan. 31, applications to the Board of Assessment Appeals are due Feb. 20 with hearings in March, and tax bills reflecting new assessments are expected in July. The assessor’s office also listed exemptions and credits (elderly/disabled homeowners, veterans, legally blind and Social Security total disability) and encouraged residents to contact the assessor’s office for information.

The presentation prompted public questions during the meeting’s public-comment period and a wide council discussion about outreach and how to help seniors and others navigate the changes. The council and staff urged residents to use the online tools and to take advantage of informal hearings if they believe their property card or valuation is inaccurate.
