Land Survey

For those seeking for real estate investments, a survey is a “due diligence” essential. It identifies if the property has the capacity for a subdivision or if an existing structure violates zoning codes. Knowing the exact acreage and topography allows an investor to accurately calculate the cost of future development or landscaping, reducing the risk of expensive “surprises” after the deal is closed.

Yes. If you are buying a home in a mature neighborhood, boundaries may have “drifted” over decades as fences were replaced and trees grew. A fresh survey ensures you aren’t inheriting a 30-year-old boundary dispute. It also confirms that the smaller lot you are moving to has no hidden easements that could prevent you from adding a ramp or a small garden shed later.

When your surveyor hands you the “plat,” check for:

• The Seal: A legal survey must be signed and stamped by a licensed professional.

• Encroachments: Any notations of structures (sheds, fences, eaves) that cross the property line.

• Setback Lines: The “invisible” boundaries where you are legally forbidden from building.

• Monuments: Descriptions of the physical markers (iron pins or concrete posts) placed at the lot corners.

While you can use tools like a tape measure or a GPS mobile app to estimate your lines, you cannot legally survey your own property. Only a licensed professional can produce a map that is legally binding in a court of law or accepted by building departments for permits. DIY measurements are fine for general gardening, but relying on them for construction could lead to a “forced demolition” if you are off by even a few inches.

Before paying for a new one, check these sources:

• The Seller: Many homeowners keep a copy in their closing files.

• County Records: Visit your local County Assessor or Recorder’s office; some surveys are filed with the deed.

• Title Company: If the home changed hands recently, the title company likely has a copy in their digital archives.

To commission a new survey, you must hire a Licensed Professional Land Surveyor (PLS). You can find them through your state’s professional licensing board or by asking your real estate agent for a vetted referral. Be prepared to provide your property’s address, a copy of your deed, and a clear explanation of why you need the survey (e.g., for a fence or a building permit) so the pro can choose the correct survey type.

Even if your lender doesn’t require one, a survey is a critical tool for:

• Installing a Fence: Ensuring you don’t accidentally build on your neighbor’s land.

• Building an Addition: Confirming you meet “setback” requirements (how far a structure must be from the property line).

• Resolving Disputes: Providing legal proof in a boundary disagreement with a neighbor.

• Title Insurance: Clearing “survey exceptions” so your insurance covers boundary issues.

• Finding Easements: Identifying where utility companies have a legal right to dig or build on your property.

In the world of homeownership, you’ll likely encounter these seven types:

1. Boundary Survey: Identifies exact property lines and corners; the most common for residential use.

2. Topographic Survey: Maps the elevations and contours of the land; essential for construction or drainage planning.

3. ALTA/NSPS Survey: The “gold standard” for high-value or commercial properties, following strict national standards.

4. Mortgage Location Survey: A basic check required by lenders to ensure the house is actually on the right lot.

5. Construction Survey: Stakes out exactly where a new home or addition should be built according to the design.

6. Subdivision Survey: Used to legally divide a large parcel into smaller, individual lots.

7. Floodplain Survey: Determines if any part of your land falls into a high-risk flood zone for insurance purposes.

The cost varies based on property size, terrain, and the type of survey required. In 2026, standard residential costs typically fall into these ranges:

• Small Urban Lots: $300 to $800

• Standard Suburban Lots (up to 1 acre): $500 to $1,500

• Large Acreage (5+ acres): $1,500 to $5,500+ Factors such as dense foliage, missing historical records, or steep terrain can push these costs toward the higher end.

A land survey is a professional scientific and legal evaluation used to determine the exact boundaries, dimensions, and physical features of a property. Performed by a licensed professional, it combines historical deed research with on-site measurements using advanced 2026 technology like robotic total stations and LiDAR drones. The result is a “plat” or map that identifies property corners, easements, and any structures (encroachments) that may cross over your lines.
