California regulates the boundary opinion
Business and Professions Code sections 8725 and 8726 make it unlawful to practice land surveying without a license or exemption and define the work to include locating or retracing property boundaries, creating or retracing subdivisions, and determining or setting survey monuments.
That distinction matters when comparing estimates. A topographic map, construction layout, or assessor parcel image may answer a different question. If your decision depends on ownership lines or corners, ask the firm to state that boundary surveying is included and identify the California PLS in responsible charge.
A Record of Survey is conditional, not universal
California's Business and Professions Code section 8762 requires a Record of Survey after specified findings, including a material discrepancy from the record, evidence that could produce alternate boundary positions, certain newly created boundary lines, or survey monuments whose positions are not already shown on an official map or record.
For a homeowner, the conditional triggers in section 8762 change the estimate conversation. Ask whether the initial research suggests a filing trigger and whether the price includes preparing, submitting, correcting, and recording the map. Some triggers cannot be identified until the surveyor has examined the record and field evidence.
Choose the deliverable by the decision
The licensed boundary functions in Business and Professions Code Chapter 15 and the filing triggers in section 8762 support different scopes for different decisions.
| Your decision | Ask for |
|---|---|
| Build a fence or improvement near the edge | Boundary determination, recovered or set corners, and any line staking the contractor needs. |
| Resolve conflicting deeds, monuments, or occupation | Boundary survey plus a clear explanation of conflicts and whether section 8762 requires filing. |
| Create or adjust a parcel | Surveying coordinated with the city's or county's land-division approval process. |
| Research only | Recorded maps, deeds, and assessor information, without treating the parcel graphic as a boundary opinion. |
Verify the professional and the scope
The California Board for Professional Engineers, Land Surveyors, and Geologists provides the official license lookup and consumer guidance. Verify the individual who will sign the work, then ask for a written scope covering record research, monuments, staking, the final map, and any county filing.
