Real Property and Tax Data
The Real Property Lister is responsible for the county’s real property listing and associated assessment functions, supplying parcel-based land information to both land information professionals and to the general public.
View Property Listing & Tax Information
NOVUS is the county’s online tax, property, and assessment information database. Use NOVUS to view property listings and tax information.
Tax ID numbers and PIN numbers are two different parcel identification numbers placed on each parcel in the county. Your PIN is a 23 digit number, while tax ID numbers are between 1 and 5 digits. Get a detailed explanation of how these PIN numbers are derived.
After a deed is recorded in the Register of Deeds office, it will move to the office of the Real Property Lister where the ownership and documentation will be updated in NOVUS.
Parcel Splits and Merges
When a parcel is either split or combined with another parcel, the Real Property Lister assigns new Tax ID and PIN number(s), adds in all appropriate ownership, documents, and basic listing information, and then sends to the assessor to add on assessment values. NOVUS is updated first, then parcel boundary updates are reflected on the GIS Web Map.

Unsure of Property Lines?
In addition to reading your deed, a survey is the best way to know your property boundaries. Please note that our GIS Web Map only shows approximate parcel lines and can be up to 200 feet off in some cases. First check if your property has a survey on it - Certified Survey Maps or CSMs (recorded) are filed in the Register of Deeds office, while maps of survey (not recorded) are filed in the Land Records Department and can be viewed using the GIS Web Map. To contact a land surveyor, see the list on our Land Surveying webpage.
