About the Darien Property Market
Darien is a city located in Fairfield County, Connecticut. Every property inside the Darien city limits is assessed by Local Assessor (varies by town), which applies Connecticut property tax rules uniformly across the county.
Because Darien property values are set at the county level, the $500,000 county median home value and 2.14% effective tax rate apply to homes throughout the city. Homeowners who believe their Darien home is over-assessed have the right to file a appeal directly with Local Assessor (varies by town) before the February 20 deadline.
Connecticut allows the assessor to defend or adjust the assessed value during a appeal, so Darien homeowners should build a strong evidence-based case before filing — which is exactly what ProtestMax generates for $45.
Darien Property Market Context
Every Darien homeowner operates under Connecticut property tax law, and understanding the state context is the first step toward a successful challenge.
Connecticut market character
Connecticut has some of the highest effective property tax rates in the country at around 2.0%, and assessed value equals 70% of fair market value. Towns revalue on a five-year cycle, and a missed revaluation can leave homeowners badly over-assessed for years.
How Connecticut handles appeals
Connecticut homeowners appeal first to the Board of Assessment Appeals, then to Superior Court for larger cases. Filing an appeal does not risk an increase in assessed value.
When to file in Darien
BAA filing deadline is February 20 (or the next business day). Missing this window locks in your assessment for another year.
