Washington Survey Guide
This Washington Survey Guide explains how boundary surveys, topographic surveys, ALTA surveys, short plat surveys, easement mapping, encroachments, corners, and legal descriptions can affect vacant land, development property, property value, and selling land in Washington State.
A survey can help clarify where a property begins and ends, whether improvements or fences cross boundaries, where easements are located, and whether a future buyer can confidently evaluate the parcel.
Why Surveys Matter for Washington Land
A survey helps identify property boundaries, corners, easements, improvements, access routes, and sometimes topography. For vacant land, inherited land, and development property, survey information can be a major part of feasibility.
County maps are not the same as surveys
Assessor maps, GIS maps, online parcel viewers, and aerial images are useful starting points, but they are not a substitute for a professional survey. Parcel lines shown online can be approximate and may not show exact corners, encroachments, easement locations, or buildable area.
Buyers often become more cautious when the boundaries, access, easements, or usable area are unclear. This can affect offer price, closing timeline, and whether a buyer proceeds after feasibility review.
- Surveys can confirm property corners and boundary lines.
- Surveys can identify encroachments or improvements crossing lines.
- Surveys can help locate easements and access routes.
- Topographic surveys can support development and engineering review.
Why this matters to sellers
Survey uncertainty can reduce land value because buyers may not know exactly what they are buying. This is especially important with older parcels, inherited land, rural acreage, shared driveways, boundary disputes, development sites, and land that has never been professionally surveyed.
A survey is not always required before selling. However, understanding whether a survey issue exists can help you decide whether to list, order more information, negotiate with neighbors, or sell directly to a buyer comfortable with uncertainty.
Important note
This guide is educational. It is not legal, surveying, engineering, title, or permitting advice. Boundary, easement, and survey questions should be confirmed by a licensed surveyor, title company, attorney, or local agency when needed.
Four Survey Questions Every Landowner Should Ask
If you own vacant land, inherited property, a development parcel, or rural acreage, these survey questions often matter most.
Where are the boundaries?
Buyers want to know where the parcel starts and ends before relying on acreage, access, or development potential.
Are there encroachments?
Fences, sheds, driveways, walls, landscaping, or utilities may cross property lines and create title concerns.
Where are the easements?
Access, utility, drainage, and shared driveway easements can affect where improvements can be built.
Is the land developable?
Topography, setbacks, critical areas, and utility routes often require survey-level information for serious development review.
Common Types of Land Surveys in Washington
Different survey types answer different questions. The right survey depends on whether the issue is boundary, access, title, development, subdivision, topography, or easement location.
| Survey Type | What It May Show | Why It Matters for Landowners |
|---|---|---|
| Boundary Survey | Property lines, corners, monuments, and boundary location. | Useful when lines are unclear, fences may be wrong, or buyers need confidence. |
| Topographic Survey | Elevation, contours, slopes, site features, trees, utilities, drainage, and improvements. | Important for grading, engineering, development design, and feasibility. |
| ALTA Survey | Detailed title-related survey commonly used in commercial or lender-driven transactions. | May show easements, encroachments, access, improvements, and title exceptions. |
| Short Plat / Subdivision Survey | Proposed lot lines, access, utilities, easements, and subdivision layout. | Important when land may be divided into multiple lots. |
| Easement Survey | Location and dimensions of access, utility, drainage, or private road easements. | Can clarify whether a parcel has practical and legal access or utility routing. |
| Construction Survey | Layout points for building, roads, utilities, grading, and site improvements. | Used after development plans are prepared and construction is moving forward. |
Not every seller needs a survey before selling
A survey can be helpful, but it is not always the best first expense. Some sellers choose to let the buyer handle survey work during feasibility, especially when the seller wants a direct sale or does not want to pay upfront costs.
Boundary Lines, Corners, and Encroachments
Boundary problems can create uncertainty in a sale. A fence, driveway, shed, wall, or landscaping feature may not match the true property line. Online parcel maps may show a general location, but exact boundaries usually require survey work.
Boundary uncertainty matters because buyers want to understand usable area, access, setbacks, improvements, neighbor conflicts, and whether any title issue may arise before or after closing.
- Are the property corners marked?
- Does a fence match the true boundary?
- Do neighboring improvements cross the line?
- Does the driveway sit inside the parcel or an easement?
- Is the legal description consistent with the parcel map?
Encroachments can affect value
An encroachment occurs when something from one property extends onto another property. Examples include fences, sheds, driveways, retaining walls, utilities, drainage structures, or landscaping.
Some encroachments are minor. Others may affect title insurance, development layout, financing, neighbor relations, or whether a buyer is willing to close.
How Surveys Help With Access and Easements
A survey can help show where access easements, private roads, shared driveways, utility easements, and drainage easements are located. This is especially important when a parcel does not front a public road or depends on another property for access.
Title documents may describe easements in legal language, but a survey can help place those rights on the ground. This can make the difference between an easement that looks useful on paper and one that actually works for a buyer.
- Is the access route inside the recorded easement?
- Is the easement wide enough for the intended use?
- Do utilities have their own rights?
- Does the easement reach the correct parcel?
- Do buildings or fences interfere with easement use?
Access and easement pages to review
Survey issues often connect directly to legal access and utilities. If access rights or utility routing are unclear, those issues may affect value as much as the boundary itself.
Why Surveys Matter for Development Land
Developers and builders often need survey information before designing a project. The survey can affect building placement, road layout, utilities, stormwater, setbacks, critical areas, grading, and subdivision potential.
Setbacks and Building Area
Survey information helps determine whether a home, townhome, driveway, or other improvement can fit within required setbacks.
Topography and Grading
Topographic surveys show elevation and slope conditions that affect grading, drainage, retaining walls, and construction cost.
Utilities and Stormwater
Survey data can help route water, sewer, power, stormwater, drainage, and utility easements through the site.
Critical Areas
Wetlands, slopes, streams, and buffers often need to be mapped before determining the true usable area.
Subdivision Potential
Short plats and subdivisions need survey work to create accurate lot lines, access, easements, and utility layouts.
Buyer Confidence
Clear survey information can reduce uncertainty and help a buyer decide whether the land is worth pursuing.
When Might a Survey Be Needed Before Selling?
A survey is not required for every land sale, but it may become important when boundaries, access, easements, development potential, or title issues are unclear.
| Situation | Why a Survey May Matter | Seller Consideration |
|---|---|---|
| Boundary dispute | Neighbor, fence, driveway, or improvement may not match the true boundary. | A survey may help clarify the issue before listing or negotiating. |
| Unknown corners | Owner or buyer cannot identify the actual property lines. | A boundary survey may improve confidence, especially on rural or wooded parcels. |
| Development parcel | Builder needs accurate dimensions, setbacks, topography, utilities, and critical areas. | Buyer may order survey during feasibility, or seller may provide one to support value. |
| Access issue | Private road, shared driveway, or easement route may be unclear. | Survey may help locate access rights but title language also matters. |
| Subdivision potential | Lot division requires accurate boundaries, frontage, access, and utility layouts. | Survey work may be part of short plat or subdivision feasibility. |
| Direct sale | Seller may not want to pay upfront for survey work. | A direct buyer may accept some uncertainty if price reflects risk. |
Can You Sell Land With Survey Issues?
Yes. Land with survey uncertainty, unclear boundaries, easement questions, or possible encroachments can still be sold. The key is understanding how the issue affects value, buyer confidence, feasibility, and closing risk.
Some sellers order a survey before listing. Others prefer a direct land buyer because they do not want to pay for survey work, resolve boundary uncertainty, or wait through repeated buyer due diligence.
- Survey-issue land may appeal to neighbors, investors, builders, developers, or long-term holders.
- Value depends on location, zoning, access, utilities, usable area, and severity of uncertainty.
- A direct sale may be practical when the parcel is hard to explain or expensive to study.

Frequently Asked Questions About Land Surveys in Washington
These answers are general starting points for landowners. A parcel-specific title, survey, legal, or county review may be needed.
Do I need a survey before selling land?
Not always. A survey can help when boundaries, access, easements, or development potential are unclear, but some sellers let the buyer handle survey work during feasibility.
Are online parcel maps accurate?
Online maps are useful but often approximate. They usually should not be treated as a professional boundary survey.
What is a boundary survey?
A boundary survey identifies property lines, corners, monuments, and boundary location based on records and field work.
What is a topographic survey?
A topographic survey maps elevations, contours, slopes, site features, and sometimes utilities or improvements for design and feasibility.
Can a survey show easements?
Yes, depending on scope and available records. Easement language usually comes from title documents, while a survey can help show the location on the ground.
Can survey issues reduce land value?
Yes. Boundary uncertainty, encroachments, missing corners, unclear access, and disputed lines can reduce buyer confidence and affect price.
Can I sell land with a boundary dispute?
Yes, but it may reduce buyer interest or price. Some buyers will still consider the land if the risk is understood and reflected in the deal.
Does a fence prove the property line?
Not necessarily. Fences may be built in the wrong location. A licensed surveyor is usually needed to confirm legal boundaries.
Can a survey help with subdivision?
Yes. Short plats and subdivisions usually require survey work for lot lines, access, easements, utilities, and site layout.
Should inherited land be surveyed?
Sometimes. Inherited land may have unclear boundaries, old easements, missing corners, or access questions, but a survey is not always required before contacting Goan.
Will buyers still buy land without a survey?
Yes. Many buyers will purchase land without a current survey, but unclear issues may affect price, feasibility, and closing risk.
