County and Public-Sector Surveyor Career Guide

County Surveyor is a recognized job title in United States surveying.

O*NET, the federal occupational database, lists it among the sample reported titles for Surveyors (SOC 17-1022.00), alongside City Surveyor, State Surveyor and Licensed Land Surveyor.

What makes the role public-side is who the work is for.

In the statutes our research verified, the office examines survey filings for its county — records of survey and corner records filed by private-practice licensees.

The duties our research verified are statutory ones, set state by state.

The clearest documented picture comes from California, where Business and Professions Code 8762 requires a licensed land surveyor or civil engineer to file a record of survey with the county surveyor in specific cases.

The triggers include, among other things, material evidence or physical change not shown on recorded maps, a material discrepancy with recorded maps, and points or lines set or reestablished that appear on no recorded map.

The county surveyor's side of that system is review.

In California, a record of survey filed with the county surveyor is examined by that office before it moves on to the county recorder.

Titles are not uniform across the country.

Ohio has no office titled county surveyor at all: its counties elect a county engineer instead.

One honest gap: our research verified statutes like these individually, but it did not confirm a national roster of which states and counties maintain a county surveyor office.

Treat the local picture as something to check with the county or the state — our research found no national list that settles it.

State law decides, and the statutes our research verified show two different models side by side.

The elected model is Ohio's.

Ohio elects a county engineer in each county every four years, under Ohio Revised Code section 315.01 — and Ohio has county engineers rather than an office titled county surveyor.

Ohio also writes qualifications into the office itself.

No one may be a candidate for, or be elected or appointed to, county engineer unless they are both a registered professional engineer and a registered surveyor licensed to practice in Ohio (Ohio Revised Code section 315.02).

The statutory-office model is California's.

California's statutes assign duties to the county surveyor as the review point for records of survey and corner records, and the provisions our research read govern what the office does with filings — they do not set out an election for it.

For a surveyor weighing a run for an elected office or an application to a hired one, the qualifications to check first are the ones the statute itself sets.

Ohio writes them into the office: both a professional engineer and a surveyor registration.

The profession-wide backdrop is licensure, too — all 50 states and DC require a license before providing surveying services to the public.

An elected office adds a campaign; a hired one adds a county hiring process.

The state's statute and the county's own rules tell you which track you are on.

What we cannot give you is a national scorecard.

Our research verified these statutes individually, and it did not compile a national roster of elective surveying offices — check the statute and the county where you want to work.

The documented core of the job is the review of survey filings, and California's filing system shows what that means in practice.

It is a two-document system, fed by the state's private practitioners.

The record of survey is the first filing type.

A licensed land surveyor or civil engineer files it when a survey discloses, among other things, material evidence or physical change not shown on recorded maps, a material discrepancy with those maps, or points or lines set that appear on no recorded map.

The law also sets a clock: the filing is due within 90 days after boundary monuments are set or the field survey is completed, whichever comes first.

The deadline extends only for reasons beyond the surveyor's control, with a letter to the county surveyor before it arrives.

Corner records are the second type.

Under California law, a signed and sealed corner record goes to the county surveyor for a Public Land Survey System corner found, set, reset or used as control.

Lost corners — as the BLM's 2009 Manual of Surveying Instructions defines them — are the exception, and establishing one takes a record of survey instead.

The county surveyor must examine the record and file it or return it within 20 working days, and the form itself is a single 8.5-by-11-inch sheet, front and back.

Public construction brings a related obligation, though the statute places it on government agencies rather than on the county surveyor.

California's monument-perpetuation statute, Business and Professions Code 8771, requires monuments controlling subdivisions, boundaries, roads or survey control to be located and referenced by a licensed surveyor before streets, highways or easements are improved, resurfaced or relocated.

The statute makes the permitting government agency responsible for ensuring that perpetuation happens — so where the county is the agency performing or permitting the work, that responsibility sits with county government.

Alongside the filing work, BLS's duty list for surveyors overall gives the occupation-wide backdrop.

Those duties span searching legal records, survey records and land titles, and measuring distances and angles.

They include using known reference points to locate features, recording results and verifying the data's accuracy.

Surveyors also prepare or supervise plots, maps and reports, and present findings to clients.

BLS rounds out the list with establishing official land and water boundaries — and testifying in court.

The toolset BLS describes for the occupation runs across that line too: handheld GPS units and robotic total stations in the field, GIS and CAD software in the office.

How much desk review and how much fieldwork a county office actually mixes varies with the county and its statute.

Public-sector surveying is bigger than the county office, and BLS's industry data sizes it.

Government accounted for 9% of surveyor jobs (SOC 17-1022) in 2025, against 71% in architectural, engineering and related services (BLS Occupational Outlook Handbook, 2025).

BLS's government category excludes state and local education and hospitals.

City government is one setting.

City Surveyor is another of O*NET's reported titles for the occupation.

Municipal duties, like county duties, are whatever the local statute and charter make them.

The state level adds a third setting, DOTs included.

Statutes can put survey obligations directly on public agencies: California's monument-perpetuation rule names the permitting government agency as the party responsible for ensuring monuments survive street and highway work.

State DOTs deserve their own search — but our research verified no DOT survey class specifications, so read each agency's own postings rather than assuming a common title.

Federal government is the fourth setting inside BLS's government category.

Among BLS's example types of surveyor, geodetic surveyors use high-accuracy technology, including aerial and satellite observations, to measure large areas of the Earth's surface.

Two cautions for the job search.

First, our research verified no federal survey class specifications either, so the same rule holds at every level: read each agency's own postings rather than assuming a common title.

Second, the licensure question follows you across all of these employers, which is the next section.

The baseline is licensure everywhere in the country.

BLS states that all 50 states and the District of Columbia require surveyors to be licensed before providing services to the public, including certifying legal documents that show property lines.

The requirement BLS describes turns on the service — providing surveying services to the public, including certifying legal documents that show property lines.

Our research did not verify how any state treats government employment under that requirement.

Whether one specific position requires the license is a question of its duties and the state's law, and the licensing board — not the job title — is the body that answers it.

A state can also write the license directly into a public office.

Ohio's is the verified example: county engineer candidates must be both a registered professional engineer and a registered surveyor licensed in Ohio.

In California, the professionals who file records of survey must be licensed land surveyors or civil engineers.

Crew and technician roles are different.

The NCEES Model Law exempts work done by employees or subordinates of a licensee when that work includes no final surveying designs or decisions and is done under the responsible charge of, and verified by, a licensee.

Responsible charge, as the Model Law defines it, means exercising full professional knowledge of and control over the work: the licensee has authority to review, change, reject or approve it.

That structure — a licensed decision-maker above an unlicensed crew — is the legal space the Model Law provides for unlicensed field staff.

The Model Law is a model, not any state's law, and each state's own statute controls.

The public-sector settings this guide covered are county surveyor and county engineer offices, city governments, state agencies — DOTs included — and federal agencies.

The 9% government share of surveyor jobs (BLS, 2025) is the measured size of that slice — a minority of the occupation, but a varied one.

Search more than one phrase.

O*NET's reported titles include County Surveyor, City Surveyor and State Surveyor, so it pays to search all of them.

In Ohio, the equivalent office is the elected county engineer — the title that state's counties actually use.

Check the county's or city's own jobs portal for its postings, and each DOT's careers site for its openings.

For the occupation behind these titles, BLS projects 6% employment growth from 2025 to 2035, faster than the 3% projected for all occupations, with about 3,100 openings a year on average — mostly to replace workers who change occupations or retire (BLS Employment Projections, 2025–35).

One requirement follows this search everywhere: certified surveying work needs a license in all 50 states and DC, and the route to one is each state board's to set.

Crew-level work sits alongside the licensed roles under the same structure the licensure section describes — the Model Law's employee/subordinate provision, with each state's statute controlling what unlicensed staff may do.
