What Is a Real Property Report and Why You Need One

A real property report is a legal document, prepared by a licensed land surveyor, that shows your property’s boundaries and the exact location of every visible improvement on the land. You generally need one when buying or selling, applying for a mortgage, pulling a building permit, or settling a boundary disagreement with a neighbor. The same document goes by different names depending on where you live: “Real Property Report” is the formal term in several Canadian provinces, while U.S. transactions more commonly call it a boundary survey, land title survey, or plat of survey. The purpose is the same in every version: an authoritative, professionally certified picture of what sits on your land and whether any of it crosses a line it shouldn’t.

What the Document Actually Shows

A finished report packs a lot of detail into what looks like a simple map. It carries the legal description of the property, the precise dimensions and compass bearings of every boundary line, and a mathematical closure confirming those measurements add up correctly. Every visible structure gets plotted: house, garage, shed, deck, fence, driveway, retaining wall, concrete patio. Each one is measured against the nearest property line.

Encroachments are among the most important findings. An encroachment happens when something built on one property physically extends across the boundary onto a neighbor’s land. A fence set a foot too far over. A roof overhang. Part of a foundation. Many homeowners have no idea an encroachment exists until a surveyor measures it, and discovering one before a sale closes is far better than discovering it afterward.

The report also maps easements and rights-of-way that burden the property. These are areas where someone else has a legal right to use part of your land, most commonly for utility lines, drainage, or shared access. An ALTA/NSPS land title survey, the most comprehensive type used in U.S. transactions, must show the location, width, and recording information of every plottable easement identified in the title evidence given to the surveyor.1ALTA Land Survey. 2021 Minimum Standard Detail Requirements for ALTA/NSPS Land Title Surveys The surveyor’s stamp, signature, and date appear on the finished document, certifying its accuracy.

When You Need One

Four situations account for most of the surveys ordered each year.

Buying or Selling Property

A current survey gives both sides confidence that the property’s physical reality matches its legal description. Buyers get confirmation that the house, garage, and fences actually sit within the lines they’re paying for. Sellers benefit because a clean survey removes a common source of last-minute closing delays. Which party pays is negotiable; sometimes the cost gets split.

Getting a Mortgage

Lenders often require a recent survey, or at minimum a title insurance policy without a broad survey exception, before they’ll fund a loan. This is especially true for new construction, rural parcels, and properties where the most recent survey is more than five to ten years old. When a relatively recent survey already exists and the seller signs an affidavit confirming nothing has changed, some lenders and title insurers will accept that instead of ordering a new one.

Building or Renovating

Local building departments commonly require a survey when you apply for a construction permit. The survey confirms that your proposed addition, deck, or detached garage will fall within the required setback distances from each property line. Pouring a foundation first and discovering it violates a setback later is an expensive mistake.

Resolving Boundary Disputes

When neighbors disagree about where one property ends and the next begins, a professionally prepared survey provides an impartial, legally recognized measurement. Courts routinely rely on surveyor testimony and certified plats to settle these disputes, so the document functions as both a practical tool and potential evidence.

How a Survey Affects Title Insurance

Title insurance policies typically include a “survey exception” in Schedule B. It is a blanket carve-out that excludes coverage for any boundary problem, encroachment, or easement conflict a survey would have revealed. If you close without a survey, your title policy will not cover you if the neighbor’s garage turns out to sit three feet onto your land, or if a utility easement runs through your planned building site.

Providing a current survey to the title company lets the insurer remove that broad exception and replace it with language specific to whatever the survey actually found. If the survey is clean, the exception essentially disappears. If the survey reveals minor issues, say a fence slightly over the line, the insurer itemizes those specific matters instead of excluding an entire category of risk. This is a meaningful upgrade in protection, particularly for the lender’s policy, and it’s one reason mortgage companies push for surveys even when regulation doesn’t strictly require one.

The nationally recognized standard for this purpose is the ALTA/NSPS Land Title Survey, developed jointly by the American Land Title Association and the National Society of Professional Surveyors.2National Society of Professional Surveyors. 2026 ALTA/NSPS Standards

Types of Property Surveys

Not every survey serves the same purpose, and ordering the wrong type wastes money.

  • Boundary survey. Locates and marks property corners and boundary lines. This is the standard survey for residential transactions and neighbor disputes. Costs typically run from $1,200 to $5,500 depending on property size, terrain, and whether prior survey records exist.
  • ALTA/NSPS land title survey. The most comprehensive option, meeting nationally standardized minimum requirements for what the surveyor must show: boundaries, improvements, easements, access points, and more. Required by many commercial lenders and title insurers. Expect to pay $2,500 or more.1ALTA Land Survey. 2021 Minimum Standard Detail Requirements for ALTA/NSPS Land Title Surveys
  • Improvement Location Certificate. A less expensive, less precise document showing the approximate location of structures relative to boundaries. ILCs explicitly state their measurements are estimates, and the certificate itself typically says it cannot be used for confirming boundaries or planning construction. Some title companies accept an ILC for routine residential closings, but it carries no surveyor liability for boundary accuracy.
  • Topographic survey. Maps elevation changes, drainage patterns, and natural features rather than legal boundaries. Engineers and architects use these when designing new construction, grading plans, or flood mitigation, not for establishing who owns what.

If you’re buying a home and your lender or title company asks for a “survey,” clarify which type. A boundary survey is usually enough for a straightforward residential purchase. An ALTA survey is the gold standard but costs roughly double and is most common in commercial transactions. A topographic survey will not answer any boundary question, no matter how detailed it looks.

What Happens When a Survey Reveals a Problem

This is where most people’s stress level spikes, but a problem found before closing is far better than one found after. The most common issues are encroachments, setback violations, and undisclosed easements.

Dealing With Encroachments

If the survey shows a neighbor’s fence or shed crosses onto the property you’re buying, you have several options depending on how serious the intrusion is:

  • Negotiate removal. For minor encroachments like a fence or landscaping, the seller or neighbor may simply agree to move the offending structure before closing.
  • Grant or obtain an easement. If the encroachment is permanent and removing it would be impractical, such as part of a foundation, the parties can formalize an easement agreement that gets recorded with the county. That legally acknowledges the intrusion and sets terms for it.
  • Adjust the boundary. The neighbor can purchase the strip of encroached land, and both parties record a new deed reflecting the redrawn line.
  • Walk away. As a buyer, a significant unresolved encroachment is a legitimate reason to terminate a purchase contract during the due diligence period.
  • Litigate. When negotiation fails, a court can order removal or award damages. This is expensive and slow, which is why every other option on this list exists.

Setback Violations and Zoning Issues

If an existing structure sits closer to a property line than current zoning allows, the municipality may have already granted a variance, or the structure may have been built before the current rules took effect and be legally grandfathered. The surveyor’s job is to measure. Determining the legal status of a violation is a question for the local building department or a real estate attorney. A seller should resolve known violations before listing, but in practice many surface for the first time when the buyer’s surveyor measures the property.

How Long a Survey Stays Current

A survey doesn’t technically expire. The boundary lines it measured haven’t moved. But its practical usefulness decays because improvements on the land change. A survey from 2015 showing a house and a detached garage won’t help you if the previous owner added a deck, extended the driveway, and built a fence since then.

Lenders and title companies generally treat a survey as too stale if it is more than five to ten years old, and even a recent survey becomes outdated the moment someone builds something new on the property. You’ll need a new survey or an update after any of the following:

  • New construction or additions on the property
  • A natural disaster that may have shifted terrain or markers
  • A boundary dispute where both sides need current measurements
  • A real estate transaction where the lender or title company won’t accept the existing survey’s age

When the only change since the last survey is minor, such as a small shed or a fence replacement in the same location, some title insurers will accept a seller’s affidavit confirming no material changes rather than requiring a full re-survey. Whether that option is available depends on the insurer, the lender, and how risk-averse everyone in the transaction is.

How to Get One

Finding and Hiring a Surveyor

Only a licensed professional surveyor can prepare a legally recognized property survey. Licensing is handled at the state level, with requirements that typically include education, examinations, and a supervised internship, followed by continuing education for renewal.3National Society of Professional Surveyors. Professional Qualifications

Start by contacting your state’s board of licensure for surveyors or searching the National Society of Professional Surveyors directory. Get quotes from at least two or three firms. Prices vary significantly based on property size, terrain, availability of prior survey records, and how comprehensive a survey you need.

What the Process Looks Like

After hiring a surveyor, the work usually follows this sequence:

  • Records research. The surveyor pulls the deed, prior surveys, plat maps, and easement documents from county records. For an ALTA survey, they’ll also review the title commitment provided by the title company.
  • Fieldwork. A crew visits the property to locate existing survey monuments, measure boundary lines, and map every visible improvement. Modern surveyors use GPS and total stations, and increasingly drones and LiDAR.
  • Drafting. The surveyor produces the final plat or report, typically within two to four weeks after fieldwork. Rush jobs are possible but cost more.
  • Certification. The surveyor stamps and signs the document.

Typical Costs

A standard residential boundary survey runs roughly $1,200 to $5,500 across most of the country. An ALTA/NSPS land title survey starts around $2,500 and goes up from there for large or complex properties. An Improvement Location Certificate, where accepted, costs less because it involves less precision and carries no surveyor liability for boundary accuracy. The biggest cost drivers are property size, whether previous survey monuments can be found, dense vegetation or difficult terrain, and how quickly you need the finished document.

Surveyor Liability and Your Protection

A licensed surveyor’s stamp means something. It is a professional certification that the measurements are accurate and the work meets applicable standards. If a surveyor makes an error, mislocating a boundary line, missing an encroachment, failing to identify an easement, the consequences can be significant: a building placed in the wrong location, a failed closing, a dispute with a neighbor based on bad numbers.

Most surveyors carry errors and omissions insurance, a form of professional liability coverage separate from general liability. Many government agencies and private developers require proof of this coverage before awarding survey contracts. If you’re hiring a surveyor, asking for proof of current E&O coverage is reasonable due diligence. A surveyor without it is asking you to absorb all the risk of their mistakes.

The window for bringing a claim against a surveyor doesn’t stay open forever. Nearly every state has a statute of repose for claims involving improvements to real property, cutting off the right to sue after a fixed number of years regardless of when you discover the error. The repose period varies widely by state, so if you suspect a survey error, acting quickly matters.
