The Assessment Lottery — City of Elmira

How the Freeze Works

In New York State, municipalities set their own assessment level and their own reassessment schedule. Elmira hasn't done a mass reassessment in many years.

Unlike many states, New York does not automatically reassess a property when it sells. The assessor has the option to update an assessment at any time, but there is no legal trigger that forces a reassessment at the point of sale. In Elmira, the data makes clear that this option is almost never exercised: from 2021 to 2025, 2,310 residential parcels had an ownership transfer (detected as a change in the owner name field between consecutive roll years) and only 44 of them received any assessment update at all. The median update for those 44 was just 8%.

A note on methodology: "ownership transfer" here means the owner name on the assessment roll changed from one year to the next. This includes arm's-length sales but also inheritance, trust transfers, LLC formations, and name corrections — so the count of 2,310 isn't a precise count of market-rate sales. The count could be somewhat high (non-sale transfers inflate it) or somewhat low (sales that closed after the March 1 taxable status date appear in the following year's roll). The core finding — that the assessor updated almost none of them — holds regardless.

The result: assessed values are essentially whatever they were when the property was last formally reassessed — which could be 5 years ago or 35 years ago. High assessed values on a given street most likely reflect properties that were updated at some point in the relatively recent past; low values reflect properties that haven't been touched since the city's last systematic effort.

What We Can — and Can't — Determine

Our data runs from 2021 to 2025. That window is enough to confirm the freeze but not to date it.

99% of Elmira residential parcels had no change in assessed value from 2021 to 2025

We can confirm that 99% of assessed values have been frozen since at least 2021, but we can't say exactly when each was last set. The NYS ORPTS dataset, our source, only goes back to 2021 for Chemung County. For properties unchanged in our window, the last reassessment could have been in 2019, in 2003, or in 1987 — the data doesn't tell us.

To find when a specific property was last reassessed, the options are: (1) a public records request to the City Assessor's office for historical assessment cards; (2) deed transfer records at the Chemung County Clerk's office, which show sales history; or (3) Beacon (the county's online assessment portal) which sometimes shows prior-year values for individual parcels. None of these provide a clean bulk dataset.

Blue — frozen, never transferred: assessment unchanged since at least 2021
Red — ownership transferred 2021–25, but assessor did not reassess
Green — transferred and reassessed (44 parcels total)
Amber — reassessed without a transfer (31 parcels — likely corrections or appeals)

The 44 That Were Reassessed — What They Have in Common

Out of 2,354 ownership transfers from 2021 to 2025, only 44 received any assessment update. Examining them reveals that these are not systematic market-value corrections — they are ad hoc condition adjustments.

16 of 44 Went down in assessed value
Distressed sales, blight, partial demolition

8 of 44 Went up more than 50%
Likely renovations or major improvements

9 of 44 Now owned by an LLC or corporation
20% of reassessed parcels vs ~5% citywide

The assessor isn't tracking market values — they're patching extreme outliers. The biggest decreases went to severely distressed properties: 707 Magee St dropped from $52,000 to $6,700 (−87%) after transferring to an investment LLC; 409 Herrick dropped from $38,000 to $10,000 (−74%). These look like condition reassessments triggered by visible deterioration, not by a sale price. The increases are similarly condition-driven — 521 Water St jumped from $52,000 to $152,000 (+192%) after a renovation.

None of the 44 look like what a systematic reassessment would produce. A true market-value update would bring assessed values up to 56% of sale price across the board. Instead, the 44 cluster at the extremes — properties so obviously changed (up or down) that the assessor couldn't ignore them — leaving the 2,310 "ordinary" transfers completely untouched.

Why Doesn't the City Just Fix This?

The inequity documented above is visible, quantifiable, and correctable — so why does it persist?

The short answer: a mass reassessment would raise taxes on the households most likely to vote against it. Long-time homeowners have the lowest assessments — their values drifted down over years of inaction. A reassessment would bring those values up toward market, increasing their tax bills. These homeowners tend to be older, more established in the community, and more reliably present at City Council meetings and the ballot box than recent buyers who would benefit from the redistribution.

There is also a practical argument the city can make: reassessment is expensive upfront. Hiring contract assessors, notifying every property owner, and staffing the appeals process that inevitably follows costs real money — and produces a politically painful outcome as its main deliverable. For a city with budget pressure, that calculus is difficult.

The alternative the city has chosen — raising the tax rate — spreads the pain proportionally across the existing assessed values. Nobody gets individually singled out. The cumulative unfairness is statistical, diffuse, and hard to mobilize around. Rate increases don't generate the same visible losers that reassessment does.

The result is a quiet penalty on economic activity. Anyone who buys a house in Elmira, or improves an existing one, ends up assessed close to market value — and pays proportionally more than a neighbor with an identical home who simply hasn't moved in 30 years. This discourages investment in property and mobility within the city, which is the opposite of what a shrinking city needs.

Who Bears the Cost

The tax levy — the total amount the city, county, and school district need to collect — is fixed regardless of how fairly assessments are distributed. That means every dollar not collected from an under-assessed property is collected from someone else.

The burden shifts invisibly toward whoever happens to have a current assessment. Two neighbors in equivalent houses can have assessments set decades apart. The one with the older, lower assessment pays less — not because their home is worth less, but because it hasn't been looked at recently. The total levy doesn't change, so the under-assessment in one place becomes quiet over-assessment everywhere else, spread across anyone whose value is reasonably up to date.

A mass reassessment would fix the distribution — everyone pays based on today's values — but it would raise taxes for long-time owners whose assessments have drifted lowest over the years. That's why reassessments are politically difficult even when they are clearly the equitable outcome.

The exemption burden is a separate problem that reassessment can't fix. Even if the city reassessed every residential parcel tomorrow, the $355M held by hospitals, colleges, and the state prison would remain completely off the tax rolls. The only tool available to address that portion of the missing tax base is negotiated PILOT agreements — voluntary payments that exempt institutions can agree to make in recognition of the city services they use.

The Arnot Health system alone represents ~$90M in assessed value and a theoretical tax liability of nearly $4.8M per year across city, school, and county levies. No PILOT agreement is currently in place. See the PILOT analysis →
