The Real Cost of Living in Fairfield, Connecticut

The 2025 Revaluation: A Lower Mill Rate, Not Necessarily a Lower Bill

Fairfield's 2025 Grand List mill rate is 19.19 per $1,000 of assessed value, applying to tax bills issued starting July 2026 -- down substantially from the prior mill rate, which had run in the mid-$20s (26.79 in the fiscal year before the revaluation). That drop is the direct result of Connecticut's state-required periodic property revaluation, which Fairfield completed in 2025: the process reassesses every property in town to reflect current market value, and because Sound-shore Connecticut real estate has appreciated substantially since Fairfield's prior revaluation, assessed values across town rose meaningfully. The mill rate then dropped mathematically to keep the town's total tax levy roughly in line with its budget -- a lower rate applied to a higher assessed value, which is very different from an actual reduction in what a homeowner pays.

Working through an example: at the new 19.19 mill rate, a home now assessed at $1,000,000 (post-revaluation) would owe roughly $19,190/year. If that same home's assessed value was, say, $750,000 before the revaluation under the old ~26.79 rate, the prior bill would have been roughly $20,093/year -- meaning in this hypothetical, the bill would actually go down slightly. But if the revaluation pushed that home's assessed value up more sharply, to $1,200,000, the new bill would be roughly $23,028/year -- higher than before, despite the lower headline mill rate. This research did not obtain the actual before/after assessed-value change for a representative Fairfield home, so it cannot state whether bills are rising or falling town-wide on net; that is a genuine, disclosed gap, and any specific property's real before/after comparison should come directly from the Fairfield Tax Assessor's office.

Southport vs. Town-Wide Fairfield Pricing

Southport carries a real, sourced premium over Fairfield as a whole: average Southport home values run around $1,508,142, up roughly 7.6% year-over-year, versus Fairfield's town-wide single-family median of roughly $1,365,000. Applying the new 19.19 mill rate to those figures directly (again assuming the assessed value tracks the market figure, which won't be exactly true post-revaluation): a $1,508,142 Southport home would carry roughly $28,941/year in property tax at the new rate, while a $1,365,000 town-wide-median Fairfield home would carry roughly $26,194/year -- both large numbers reflecting Fairfield County's high Sound-shore price environment generally, not something specific to the new mill rate itself.

No State Assessment Cap

Connecticut has no statewide cap on annual assessment increases comparable to Florida's Save Our Homes or California's Proposition 13 -- Fairfield's 2025 revaluation, discussed above, is a direct real-world example of what that means in practice: assessed values can jump substantially at each periodic revaluation cycle (state law requires one at least every five years) rather than being smoothed by an annual cap. A buyer relocating from either of those capped-assessment states should treat Fairfield's 19.19 rate as a snapshot tied to this specific 2025 revaluation cycle, not a permanently low number.

Insurance and Sound-Shore Flood Risk

Fairfield's coastline, including Southport Harbor and the town's broader Sound-front neighborhoods, carries real flood-zone exposure -- a standard homeowners policy excludes flood damage, and any waterfront or near-waterfront Fairfield property needs a separate NFIP or private flood policy priced off an address-specific FEMA flood-zone determination. This research did not obtain a Fairfield- or Southport-specific homeowners or flood-insurance premium average this session; that is a genuine, disclosed gap, and any buyer evaluating a specific parcel should get an actual quote from a licensed Connecticut agent rather than relying on a general Fairfield County average.

Putting the Real Number Together

For a representative $1.3-1.5 million Fairfield or Southport purchase post-revaluation, a realistic annual recurring-cost floor looks roughly like: $25,000-$29,000-plus in property tax at the new 19.19 mill rate, calculated against the property's actual new (post-2025-revaluation) assessed value rather than its market price directly; a homeowners policy plus a separate flood policy for any Sound- or harbor-adjacent parcel, both requiring an actual quote given this page's disclosed lack of a confirmed local premium average; and confirmation from the Fairfield Assessor of exactly how the 2025 revaluation changed that specific property's assessed value, since this page cannot state whether any individual buyer's bill will run higher or lower than the pre-revaluation number. None of this substitutes for an actual current tax card and actual insurance quotes -- but it is a far more honest starting budget than the headline 19.19 mill rate alone.
