Frozen Assessments

A note on method. "Ownership transfer" here means the owner name on the roll changed from one year to the next. That covers ordinary sales, but it also covers inheritance, trust transfers, LLC formations and name corrections. So 2,354 is not an exact count of market sales. It could run a little high, because non-sale transfers inflate it. It could run a little low, because a sale closing after the March 1 taxable status date lands on the following year's roll. Either way the core finding holds: the assessor updated almost none of them.

So an assessed value is whatever it was the last time that property was formally reassessed. City-wide, that was 1995. A parcel the assessor never singled out still carries a number set 31 years ago. On any given street, the higher assessments are probably the houses touched at some point since. The lower ones are the houses nobody has looked at since the city's last systematic effort.

New York publishes an equalization rate for every municipality: assessed value as a percentage of what the state estimates the property is actually worth. It is the cleanest measure of a frozen roll there is. Every year the assessor does nothing, the rate falls a little: market values rise while assessments sit still. The year a city reassesses, it jumps back to about 100.

Elmira's line does that twice. The roll drifted from 48% of market value in 1970 down to 13.8% by 1994. The 1995 revaluation snapped it back to 112.9%. And then the same slide started again: 56% as of 2025, and still falling. The city is now about as far adrift as it was in the mid-1970s, on the way down to the last reassessment.

Source: NYS Department of Taxation and Finance, equalization rates (data.ny.gov e6pv-77bh), City of Elmira, SWIS 70400 — compiled into equity.json by scripts/visualize_equity.py. The dataset reaches back to 1954. The earliest years repeat one rate for up to five years at a time, which means infrequent surveys rather than annual measurement. So the chart starts in 1970, where the series begins moving every year. Full method on the Data & Sources page.

The city also has a practical argument. Reassessment costs money up front. You hire contract assessors. You notify every property owner. You staff the appeals that always follow. All of it costs real money, and what it buys is a politically painful result. For a city already under budget pressure, that is a hard sell.

So the city does the other thing. It raises the tax rate. That spreads the pain across the assessed values already on the books, and nobody is singled out. The unfairness that builds up is a statistic. It is spread thin, and it is hard to organize against. A rate increase does not create the visible losers a reassessment does.

The result is a quiet penalty on visible investment. A sale almost never triggers a reassessment. A major renovation can. So the owner who fixes up a house risks being assessed near its new market value, while the identical house next door stays frozen at a decades-old number. That discourages exactly the upkeep a shrinking city needs.

The tax levy is the total the city, county and school district need to collect. That total is fixed. It does not care whether assessments are fair. So every dollar not collected from an under-assessed property gets collected from someone else.
