How Do I Find a Licensed Land Surveyor in Washington County, Oregon?
Washington County is the western anchor of the Portland metro area, running from the dense suburbs of Beaverton and Tigard at its eastern edge to the agricultural and timber lands near Banks at its western foothills. The county seat, Hillsboro, is home to Oregon's largest concentration of high-tech manufacturing. Tualatin, Sherwood, Forest Grove, and Cornelius fill out the county's cities. The flat Tualatin Valley floor, the Tualatin Mountains to the east, and the Coast Range foothills to the west mean surveyors here work across sharply different conditions depending on where in the county the property sits.

Oregon licenses all surveyors through the Oregon State Board of Examiners for Engineering and Land Surveying (OSBEELS) under ORS Chapter 672.

Common Reasons Washington County Property Owners Need Surveys
Hillsboro Residential Lot Line Adjustments
Hillsboro's older residential neighborhoods, built in waves from the 1960s through the 1990s, include a significant number of lots where fences, driveways, and landscaping have drifted away from the legal boundary over decades. When homeowners want to formalize a boundary adjustment with a neighbor, sell, or add a structure near a setback, a boundary survey is needed to establish the correct legal line. Lot line adjustments must be prepared and recorded by a licensed PLS and require a formal survey document.
Beaverton New Subdivision Stakeout
Beaverton is one of the most active residential development markets in Oregon. New subdivision projects in Beaverton require construction stakeout services to mark lot corners, building envelopes, and utility alignments before permits are issued. Surveyors handling Beaverton subdivision work typically coordinate closely with city engineers to ensure staked positions match approved development plans.
Forest Grove Rural-to-Urban Transition Parcels
Forest Grove sits at the western edge of the Tualatin Valley where agricultural land transitions to suburban development. Parcels in this zone often carry a mix of agricultural easements, old right-of-way dedications, and deed descriptions from rural-era conveyances that predate modern subdivision. Owners partitioning land, selling to developers, or clarifying boundary positions on these transition parcels benefit from a surveyor experienced with mixed-vintage deed records.
Tualatin Commercial Boundary Surveys
Tualatin's commercial corridors along Boones Ferry Road and Interstate 5 are active for retail, industrial, and distribution development. Commercial boundary surveys in Tualatin involve right-of-way research along major arterials, utility easement documentation, and in some cases flood zone analysis near the Tualatin River. ALTA/NSPS surveys for commercial transactions here run $2,000 to $4,500 for most mid-size properties.
Banks Agricultural Parcels Near the Urban Growth Boundary
Banks is at the western edge of Washington County, beyond the Portland metro urban growth boundary, surrounded by farming and timberland in the Coast Range foothills. Agricultural parcels near Banks change hands for farm use, rural residential development, and occasionally conservation purposes. These surveys involve large tracts, older iron pin monuments, and terrain that demands more field time than valley floor work. Banks-area owners typically need two to four weeks of scheduling lead time with an experienced rural surveyor.
What to Expect from the Survey Process in Washington County
Getting a Quote
When calling Washington County surveyors, have your parcel number from Washington County Assessment and Taxation ready, along with any prior surveys, deeds, or plat documents. State the purpose clearly: a fence project, a commercial closing, a partition, and a new building permit all have different deliverables and costs.
Scheduling Lead Times
Washington County is a high-demand survey market. Residential surveys typically require two to four weeks of lead time. Commercial ALTA surveys and partition surveys take four to six weeks or more. Spring and summer see the heaviest scheduling pressure. If your project has a deadline tied to a closing, permit, or construction start date, engage surveyors early.
Fieldwork and Plat Delivery
After scheduling, the surveyor's crew visits the property for monument searches, boundary measurements, and control establishment. For standard residential lots in Beaverton or Tigard, fieldwork takes one to two days. Rural parcels near Forest Grove or Banks may require additional days. After fieldwork, the surveyor prepares the final plat or record of survey, typically within two weeks of field completion. Oregon requires the surveyor to stamp and sign all survey documents before they can be recorded.
