What to check on your notice
If your 2026 notice shows a higher value than last year, ask why. The typical Glen Park home lost 5.8% over the same stretch. A higher number can still be right for a specific home, for example after a remodel, but the town or city assessor should be able to explain it.

Deadline and where to file
Glen Park values are set by the local town or city assessor. Most towns and cities: file Form RP-524 by Grievance Day, usually the fourth Tuesday in May. Exceptions: Suffolk towns meet the third Tuesday in May, Westchester towns the third Tuesday in June, villages that assess typically the third Tuesday in February, and some shared-assessor towns pick a date between the fourth Tuesday in May and the second Tuesday in June. NYC: March 15 for Class 1 homes and March 1 for all other classes. Nassau County: March 1.
Reading this in fall 2026? The 2026 Grievance Day has passed in nearly every community, and the 30-day window to file SCAR after the final roll has too. Your next chance is for the 2027 roll, and it depends on where you live. Based on the usual rules (dates not yet confirmed for 2027), villages that assess may meet around February 16, 2027, NYC and Nassau deadlines are around March 1 (NYC Class 1 around March 15), most towns and cities around May 25, Suffolk towns around May 18, and Westchester towns around June 15. Call your assessor to confirm, because missing Grievance Day forfeits both the board hearing and judicial review for that year.

Building a Glen Park case
Averages explain why a case might work. The decision turns on evidence about one property. Glen Park is part of the Watertown-Fort Drum metro, but your evidence should be local. Sales a few streets away usually beat sales across the metro.
- Use recent sales of comparable homes that sold for less than the assessor's implied market value.
