South Dakota's 66 counties maintain property records through the county director of equalization and register of deeds.

5 Ways to Find Your Property Lines in South Dakota

1

Check County Records Online

South Dakota has 66 counties, and many offer online GIS or parcel viewer tools where you can look up property boundaries by address or parcel number. Start with your county assessor or recorder's office website.

The accuracy and availability of online records varies by county. Some provide detailed interactive maps, while others may require an in-person visit to the county office.

2

Review Your Property Deed

Your property deed contains a legal description of your land, including metes and bounds measurements or lot and block references. You can find your deed at the county recorder's office or through your title company.

While the deed defines your legal boundaries, interpreting the description on the actual ground can be difficult without surveying knowledge or equipment.

3

Look for Physical Markers

Section corners, iron pins, and USGS monuments. Black Hills area has different marker patterns than the open prairie. Badlands terrain can shift markers.

4

Hire a Licensed Surveyor

A professional land survey in South Dakota typically costs between $300 and $700, depending on parcel size, terrain, and complexity. A licensed surveyor will physically mark your boundary corners with stakes or monuments.

South Dakota requires surveyors to be licensed by the Board of Technical Professions.

5

Use ParcelVision AR

ParcelVision uses augmented reality to show property boundary lines right on the ground through your iPhone camera. Just search an address, unlock the property for $14.99, and walk the lines in real time.

Unlike a survey that takes weeks to schedule, ParcelVision gives you instant results — and you can share access with anyone for free. It's ideal for getting a quick visual understanding of where your property lines are before committing to a full survey.

When You Need a Professional Survey

While ParcelVision is great for visualizing property lines on the ground, there are situations where a licensed land survey is the right call. A professional survey provides a legally binding document and precise measurements that hold up in court.

  • Legal disputes — If you're in a boundary disagreement with a neighbor, a certified survey is the only document that carries legal weight. South Dakota has an adverse possession period of 20 years, making boundary clarity especially important.
  • New construction — Building a fence, addition, or structure near your property line typically requires a survey to obtain permits and avoid setback violations.
  • Buying or selling land — A current survey protects both buyer and seller by confirming the property's exact boundaries, easements, and encroachments.
  • Subdividing property — Splitting a parcel into multiple lots requires a formal subdivision survey filed with the county.
  • Title insurance claims — If there's a question about boundary location during a title search, a survey resolves the issue definitively.

For everything else — walking your land, understanding your boundaries before buying, checking a fence line, or showing a hunting group the property edges — ParcelVision gives you the answer in minutes for $14.99.
