Clackamas County stretches from the south Portland suburbs to the edge of the Cascade foothills, covering everything from dense suburban lots in Lake Oswego and West Linn to forested acreage near Sandy and Estacada. That geographic range translates directly into cost variation: a boundary survey on a compact urban lot runs as low as $800, while a rural acreage survey east of the county can approach $1,800. In 2026, here is what property owners can expect to pay across the main survey types.
Boundary Survey Costs in Clackamas County
Boundary surveys establish the legal corners and lines of a parcel. In Clackamas County, expect $800 to $1,800 depending on location and parcel characteristics.
Urban and suburban lots (Lake Oswego, West Linn, Milwaukie, Happy Valley): These lots benefit from well-maintained plat records and relatively straightforward access. Surveys in the $800 to $1,200 range are common for standard residential parcels. Lake Oswego, in particular, has a dense suburban grid where research and field work are efficient.
Rural and foothill properties (Sandy, Estacada, Molalla, Canby): Moving east toward the Cascade foothills, parcels grow larger and terrain gets rougher. Sandy and Estacada properties often involve acreage with older metes-and-bounds descriptions, heavy tree cover, and longer field days. Expect $1,200 to $1,800 for rural boundary work in these areas.
Oregon City, the county seat, holds the deed and plat records that surveyors rely on for research. Survey firms factor in records research time when pricing a job, so properties with complex deed histories or older legal descriptions cost more.
ALTA/NSPS Land Title Survey Costs
ALTA surveys are used in commercial real estate transactions and by institutional lenders. They combine boundary survey work with title research, showing easements, encroachments, and other matters relevant to title. In Clackamas County, ALTA surveys run $2,000 to $4,500.
Commercial properties in Milwaukie and Tualatin (the western edge of the county) are common candidates. The upper end of the range applies to larger parcels, complex easement situations, or properties where the title commitment includes many items to locate and map.
Construction Stakeout and Lot Line Adjustments
Construction stakeout for new builds in Happy Valley and Canby typically runs $500 to $1,200 depending on scope. Lot line adjustments, common in Lake Oswego and West Linn where lot consolidations and splits happen with some frequency, usually cost $900 to $1,500 including the survey work and plat preparation.
Elevation Certificate Costs
The Clackamas River runs through the heart of the county, and portions of its floodplain near Oregon City and Canby fall within FEMA Special Flood Hazard Areas. The Willamette River borders the county’s west edge, with floodplain areas in Gladstone and Oregon City. Properties in these zones may need an elevation certificate for flood insurance. Elevation certificates in Clackamas County cost $350 to $600.
What Drives Survey Costs in Clackamas County
A few factors push costs up or down regardless of survey type. Access difficulty matters: properties in the Sandy River corridor and along steep Cascade foothill terrain require more field time. Parcel size is a direct driver of cost for acreage surveys near Estacada and Molalla. Dense vegetation, common in the county’s heavily wooded eastern portions, slows GPS work and increases field time.
Deed research complexity also adds cost. Properties platted under older Oregon land grants or those with multiple easements and rights-of-way require more research before any fieldwork begins.
Hiring a Licensed Surveyor in Clackamas County
