It's remarkable all the information you can gather on this site. If you want to do research on your home or municipality this is the place to start! You can check your current assessment, exemption(s) status, and physical information about your property. You're also able to research other properties, even going to other municipalities in Genesee County. If you would like to research recent property sales information you can search by town or a specific street. You'll be able to find sale price, lot size, square footage and more. This is a great way to see how your home compares with others in the area.

If you disagree with your assessment, there's information about the informal review process with PDF forms to print out to guide you through the process.

Please be assured that the goal of the assessor's office is to correctly describe each property and determine the fair and equitable assessment for your property.
