Are Plat Maps Public Record? (How to Find Recorded Plats Online)
Usually, yes — if you mean a recorded plat. A recorded plat is generally a public land record filed with a county recorder, register of deeds, clerk, or another local recording office. But “public record” does not always mean “free PDF one click away.” County indexing, digitization, search rules, and copy fees vary. An interactive county parcel viewer can help you find the right property, but it is not the same document.

The short answer: recorded plats are generally public records
When a subdivision plat, condominium plat, replat, dedication, or similar map has been accepted and recorded, it becomes part of the public land-record system in that jurisdiction. The office name changes by state and county: you may be looking for the county recorder, register of deeds, clerk of court, land records office, or a clerk-recorder. Some counties route plats through a planning or surveyor’s office before the final filing, so the county’s land-records page is the best starting point.
Public access is not identical everywhere. One county may provide a searchable scan by plat book and page; another may show an index but require an online order, an email request, an in-person visit, or a fee for a certified or oversized copy. Older plats may still be in paper volumes or image archives that have not been fully indexed. A result that is not online is not necessarily private — it may simply require a different request path.
Recorded plats vs. a county parcel viewer
A recorded plat is an official filed drawing or land-record instrument. It may include lot and block numbers, dimensions, bearings, easements, rights-of-way, dedications, monuments, approvals, notes, and a recording stamp. Its title, date, book/page, or instrument number gives you a trail back to the public record.
A county parcel viewer is a web map built for searching and displaying GIS or tax-parcel information. It may let you search by address, owner, parcel ID, or subdivision, then click through to assessment details or links. The viewer can be extremely useful for orientation and for identifying a plat name or nearby parcel. Its polygon is often a mapping or assessment layer, however, not a scanned copy of the recorded plat. It can be generalized, shifted for display, awaiting an update, or based on a different source.
Think of the two tools as complementary: use the parcel viewer to locate the property and clues; use the county’s recording system to retrieve the filed plat and related documents. Do not treat a clickable line on a parcel viewer as a survey boundary.
An unrecorded sketch is not the same as a recorded plat
People use “plat” loosely for many drawings. A preliminary subdivision layout, marketing sketch, hand-drawn lot plan, GIS screenshot, survey exhibit, or map attached to an unrecorded agreement may be useful evidence or background, but it is not automatically a recorded plat. It may never have been approved, accepted, indexed, or filed in the public land records.
Look for a recording stamp, instrument number, book and page, certified signatures, clerk or recorder notation, and the actual county source. A copy with no filing reference should be described as an unrecorded sketch or plan unless the responsible office confirms otherwise. A recorded plat can also be amended, vacated, or supplemented, so check for later filings rather than relying on the first drawing you find.
How to find a recorded plat online
- Identify the county. Start with the property’s county, not just the city or mailing address. Plat records usually follow the county’s land-record system.
- Open the official county site. Search for the county recorder, register of deeds, clerk land records, or plat recording page. A county parcel viewer may be the fastest route to the subdivision name, parcel number, or legal description.
- Search the index. Try the subdivision name, plat book and page, instrument number, lot and block, grantor/developer name, or legal description. Search rules and date ranges differ.
- Check related filings. Look for replats, amendments, vacations, dedications, condominium declarations, easement documents, and deeds that reference the original plat.
- Ask about copies and fees. The online image may be free to view while downloads, certified copies, large-format scans, or staff research cost extra. Follow the office’s current instructions.
If the recorder’s search is hard to use, write down the subdivision and recording clues from the county parcel viewer and send a focused request to the recording office. Platbookmapper can help you find the county’s official starting point: we link out to county GIS and parcel viewers rather than hosting or redrawing their data.

Is a public plat free to view or copy?
There is no nationwide answer. “Public record” generally describes access rights, not a promise that every image, download, staff search, or certified copy is free. A county may offer free browser viewing but charge per page for a reproduction. Another may charge a convenience or subscription fee for online land-record images while allowing inspection at the office. Certified copies and oversized plat sheets commonly have different fees.
Before paying, confirm whether you need an uncertified research copy, a certified copy, or simply the book/page and instrument number. For a transaction or legal filing, ask the title company, attorney, or recording office what format is required.
Why a survey still matters
A public plat is valuable research, but it is a snapshot of recorded information, not a field inspection of current conditions. Deeds, senior rights, monuments, improvements, later easements, and occupation lines can change how a boundary question must be analyzed.
Required reminder: A licensed survey is the most accurate way to establish property lines for legal purposes. Public plats and parcel viewers are for research and orientation, not a substitute for a survey. Do not rely on them for disputes, fences, closings, or construction.
Recorded plat and parcel viewer FAQ
Are recorded plats public records?
Generally, yes. Recorded plats are usually filed with a county recorder, register of deeds, clerk, or comparable land-records office. Access and copy procedures vary by state and county.
Is a county parcel viewer a recorded plat?
No. A parcel viewer is an interactive GIS or tax map. It may help you find a subdivision or parcel, but the recorded plat is the filed document with its own recording reference.
Are unrecorded plat sketches public records?
Not automatically. An unrecorded sketch or preliminary plan is not the same as an accepted, filed recorded plat. Confirm the recording stamp and instrument reference with the county.
Can I use a plat or parcel viewer to place a fence?
No. A licensed survey is the most accurate way to establish property lines for legal purposes. Public plats and parcel viewers are for research and orientation, not disputes, fences, closings, or construction.
