Why the plat map matters before you close
A plat can show the recorded subdivision lot, dimensions, streets, and easements, while a fence, driveway, or maintained yard shows present-day occupation. Comparing them can reveal questions that need a survey, title review, or municipal confirmation.
A Washtenaw County parcel map is an assessment and research layer; a recorded plat documents the subdivision as filed. Neither one, by itself, locates the boundary on the ground.
What a plat map shows
A recorded subdivision plat depicts the lots, streets, easements, dimensions, monument information, dedications, or other details shown when it was filed. Read the specific plat and its notes because drawings differ.
A surveyor relates relevant record and field evidence within a stated scope. A parcel map is a GIS representation used for assessment and public research. For an aerial reference, the property-line map online guide explains what the county layer can and cannot establish.
Use the plat as one record in the file, together with the deed, later recorded instruments, and any relevant survey.
Plat maps in Washtenaw County
Washtenaw County records plats through the Register of Deeds. A property file may also include later plats, amendments, divisions, combinations, condominium documents, easements, road records, or other instruments. Use the deed or title material to identify the records relevant to the parcel.
Current zoning and building requirements are separate from the original plat. If a purchase depends on an addition, fence, accessory structure, division, or change of use, confirm the current rules with the city or township.
How to get a plat map online for a Washtenaw County property
Start with the deed, title commitment, or assessor record to identify the parcel number, legal description, subdivision name, and any liber-and-page or document reference. Use the Washtenaw County Register of Deeds search instructions and available indexes to locate the plat; contact the records office if the online search does not return the document.
Use MapWashtenaw as a second reference for the parcel number, taxing jurisdiction, and approximate parcel geometry. A difference between the GIS outline, plat, legal description, or visible occupation is a question to resolve, not proof that the parcel was reconfigured.
The applicable city or township can provide current zoning maps and explain how to request local approvals or site-plan records.
- Use the Register of Deeds search options and the recording references from the deed or title material.
- Open the recorded plat image and note the applicable lot, block, dimensions, notes, and easements shown in the document.
- Compare the plat reference with MapWashtenaw for parcel orientation, without treating the GIS outline as a field boundary.
- Ask the responsible municipality for current zoning, setback, and project requirements.
- Check for later recorded instruments or municipal approvals that affect the parcel.
What the plat map will and will not prove
A recorded plat documents the subdivision geometry, streets, dedications, and easements shown when it was filed. A surveyor can locate a corner or fence in the field, and the municipality can confirm compliance with current zoning and building requirements.
Treat the plat as a starting record. A licensed surveyor can compare the record evidence with field conditions, and the municipality, title professional, or attorney can address questions within its own role.
Put the plat in context
Use the plat and parcel record to understand the recorded layout. Confirm a boundary in the field with a surveyor and a building plan with the municipality.
