How to choose a grievance firm

Long Island has dozens of grievance firms. They mostly fall into three groups:

  1. Local generalist firms — family-owned, decades of experience with specific town BARs. Best for "I want a phone call from a real person."
  2. Volume firms — advertise heavily, file thousands of cases per cycle. They batch-file and rarely customize per-parcel evidence. Often cheapest contingency.
  3. Attorneys / tax certiorari specialists — only worth it for high-value properties ($1.5M+) where SCAR or Article 7 proceedings can be cost-effective.

Questions to ask before signing

  • Is the fee strictly contingency? (You should pay $0 if there's no reduction.)
  • What percent of the first-year savings? (Industry standard: 50%. Some firms charge less.)
  • Does the contingency apply to year 1 only, or multiple years? (Multi-year contingency is a red flag.)
  • Do they handle the ARC / BAR hearing themselves, or pass it to staff?
  • Will they pursue SCAR if the BAR denies the initial reduction?
  • What's their success rate for properties similar to yours in this town?

What "filing on your own" looks like

Filing your own grievance is free and often successful. You'll need:

  • Form RP-524 (Suffolk towns) or AR1 (Nassau) — one page
  • Recent comparable sales (Zillow, Redfin, MLS via your realtor)
  • A photo of any defects (deferred maintenance, awkward floor plan, etc.)
