What kind of survey do you need?

Cost by project type
Use this as a planning range. A firm still needs the property context before it can give reliable pricing.
| Project type | Typical range | Best fit | What changes the estimate |
|---|---|---|---|
| Residential boundary survey | $700 to $2,500 | Fences, additions, property lines, purchases | Lot shape, records, corner evidence, access, easements, and dispute risk. |
| Boundary staking | $600 to $2,000 | Marking corners or lines before work starts | Number of points, missing monuments, terrain, and whether retracement is needed first. |
| Hillside boundary or topo package | $2,000 to $8,000+ | Hillside additions, retaining walls, grading, slope work | Contours, spot elevations, drainage, access, walls, and design-team requirements. |
| Topographic survey | $1,500 to $6,000+ | Architecture, engineering, drainage, ADU, pool, or site planning | Detail level, hardscape, utilities, trees, CAD files, slopes, and jurisdiction comments. |

Why Los Angeles County changes the price
Hillside terrain and grading context
If the project touches slope, retaining walls, drainage, or earthwork, boundary-only pricing is usually the wrong planning number.
LA County Public WorksCoastal, flood, and watercourse issues
Malibu, Santa Monica, Long Beach, Venice, low-lying basins, and channel-adjacent parcels can add flood, bluff, drainage, and elevation questions.
California Coastal CommissionJurisdiction and permit path
The survey question can change depending on whether the property is in Los Angeles, Long Beach, Santa Monica, Malibu, Pasadena, Glendale, or an unincorporated area.
LA County PlanningRecords, APNs, and land records
Assessor and Public Works records help prepare the request, but they do not replace a licensed boundary determination.

How to verify a Los Angeles County surveyor
California land surveying is regulated by the Board for Professional Engineers, Land Surveyors, and Geologists. Before hiring, use BPELSG license lookup to confirm the responsible professional's current status, then ask whose seal will appear on the final deliverable.
Start with the Los Angeles County land surveyor directory, then confirm license status, service area, scope, timeline, and written pricing directly with the firm.
