How to appeal

If your assessment is higher than comparable sales in your area, you can appeal. File with your county Board of Assessment Appeals within the deadline on your notice (typically 30-90 days). Bring 3-5 recent comparable sales ("comps") pulled from Zillow or your county recorder. The process is free.

What drives reassessment

Triggers include your purchase price being recorded at county, permitted renovation work, and periodic mass appraisals. New construction is always assessed on completion.
