Where the recorded documents are

On the ground

Rights that may be separate
Rights below the surface near Cedarville may belong to someone else, which a title search can uncover.
Rules that come with the land

What the map can't tell you
For a parcel near Lake Summerset, listed acreage is a tax-roll number; only a licensed surveyor sets the real boundary on the ground. For a home near Lake Summerset, records update in batches, so a deed recorded last month may not show yet.
Getting answers from the right desk
If the acreage or value on a parcel near Lake Summerset looks off are handled by the Supervisor of Assessments, working with township assessors, the office behind the parcel record. Zoning, permits and septic questions near Orangeville go to planning, building or health offices, town or county, depending on location.
