The hook
State surveying boards publish codes of conduct that bind every PLS. Principles are the starting point; the rules are specific — what is prohibited, what is required, what triggers discipline.
Memorize these
Concepts that show up on the exam
Public protection (paramount)
The public health, safety, and welfare comes first — before client wishes, before personal interest.
Practice within competence
Don't accept work outside your training/experience. Refer to a specialist or decline.
Practice within license scope
PLS authorizes surveying — not engineering, not legal advice. Stay in your lane.
Conflict of interest disclosure
Personal/financial interest that could compromise judgment must be disclosed in writing to the client. Recuse if disclosure isn't enough.
Honest reporting
No misrepresentations. Survey shows what you found, including discrepancies and uncertainties.
Sealing only what you supervised
A PLS's seal certifies the work was done under their direct/responsible supervision. Sealing work you didn't supervise is grounds for discipline.
No solicitation by deceit
Truthful advertising. No misleading credentials. No signature forgery. Most state boards have specific advertising rules.
Mandatory reporting
Some states require reporting incompetent or unethical conduct of other surveyors. Failure to report can itself be a violation.
