How to Split or Combine Property in St. Clair County

The County of St. Clair assists in the maintenance and updating of property descriptions, taxpayer name and address records for all 31 local assessing units (23 townships, 8 cities and 2 villages). Available to residents are property maps, which are updated as new information is obtained and aerial photos.

Property Split and Combination CHECKLIST:

  1. Contact your local municipality to verify the zoning requirements; frontage/acreage, usage, access; to assure requested change meets the local ordinances. The local assessor is your main contact person, the listing can be found here.

  2. IF creating a new taxable parcel, acquire documentation to show adequate easements for public utilities as per the State Land Division Act. This involves contacting the local municipality to find what utility easements will be necessary. A combination or transfer to adjacent parcel should not need to have easements done, as they most likely are already in place, please check with your local municipality to make sure everything is in order.

  3. Contact the St. Clair County GIS Department at (810) 989-6920 to set up an appointment for review of the proposed split/combination. An administration fee of $25 is charged at this time for processing.

  4. Contact the St. Clair County Road Commission for a driveway evaluation on the resulting parcels.

  5. Submit all your approval letters, completed land division application, maps and new property descriptions to the municipality for final approval.

  6. A copy of the land division application, approvals and necessary documents need to be forwarded to the St. Clair County GIS Department to ensure the property will be split on the tax roll.

  7. You can now sell or transfer the property. Please note: a legal name change and a deed should be recorded with the register of deeds office for the split to be recognized per P.A. 591.
