Land surveyors in St. Louis: licensed Missouri and Illinois surveyors, quoted
Land surveyors in St. Louis work across a fifteen county, two state metro of about 2.81 million people, so the first question is always which state board licensed the person sealing your plat: Missouri licenses a Professional Land Surveyor under 20 CSR 2030-16, Illinois licenses a Professional Land Surveyor under 68 Ill. Adm. Code 1270.56, and the license has to match the state the land sits in rather than the state the office sits in. The St. Louis fact that costs people the most money is a filing rule: under RSMo 60.650 a Missouri surveyor only has to file the survey with the recorder of deeds when it creates a new parcel of land, so an ordinary retracement of your existing lot is usually never recorded anywhere, and the copy in your file is the record. The metro also has three separate records systems, because the City of St. Louis has run its own county level offices since it separated from St. Louis County in 1876. A St. Louis boundary survey typically costs $500 to $1,100. Surveyors.io publishes each license number exactly as the surveyor entered it and does not verify it, so check it on the board lookup linked on this page before you hire.

Two states, two boards: which license your St. Louis surveyor actually needs
The St. Louis metropolitan area is fifteen counties spread across Missouri and Illinois, with a combined population estimated at 2,814,421 in 2025. Half of the practical questions people ask about a survey here come down to which side of the Mississippi the parcel sits on.
On the Missouri side the metro runs through the City of St. Louis (278,144 residents), St. Louis County (990,911), St. Charles County (426,499, the fastest growing county in the region), plus Jefferson, Franklin, Lincoln and Warren counties. On the Illinois side, the area locals call the Metro East covers Madison, St. Clair, Monroe, Clinton, Bond, Macoupin, Jersey and Calhoun counties.
Missouri licenses a Professional Land Surveyor and holds that person to the Missouri Standards for Property Boundary Surveys at 20 CSR 2030-16. Illinois licenses its own Professional Land Surveyor through the Illinois Department of Financial and Professional Regulation, working to the minimum standards of practice at 68 Ill. Adm. Code 1270.56. The two rulebooks are not interchangeable, and neither is the seal.
The rule that trips people up: the license has to match the state the land is in, not the state the surveyor's office is in. A well regarded firm in Chesterfield or Kirkwood cannot seal a boundary survey in Belleville or Edwardsville unless someone in responsible charge holds an Illinois license, and the reverse is equally true. Plenty of St. Louis firms carry both. Plenty do not. Ask before you sign, and check the license number against the right state board rather than assuming a familiar local name covers both sides.
This matters more here than in a single state metro because so many St. Louis buyers, builders and attorneys work both sides of the river routinely. A surveyor who did excellent work on your Webster Groves house may have to subcontract or decline your Columbia, Illinois lot, and finding that out two weeks before closing is expensive.
The St. Louis myth: "my survey is on file with the county"
It usually is not. Missouri only makes the surveyor file when the survey creates a new parcel of land, which is not what happens on an ordinary residential boundary survey.
The statute is short and it decides the whole question. RSMo 60.650 says that for the purpose of preserving evidence of land surveys, "every surveyor who establishes, restores, or reestablishes one or more corners that create a new parcel of land shall file the results of such survey with the recorder of deeds in the county or counties in which the survey is situated within sixty days after the survey has been certified."
Read the trigger carefully. The duty attaches to creating a new parcel. If a surveyor retraces the lines of a lot that already exists, finds the old pins, sets replacements and hands you a sealed plat, no filing duty arises under 60.650. That is the most common job in the metro and it is the one people assume is on file somewhere. It generally is not. Your sealed copy, plus the surveying firm's own project file, is the record.
This is very different from neighboring states. Arkansas makes plat filing mandatory within 30 days under A.C.A. 17-48-106, Oklahoma requires a Certified Corner Record within 90 days for every public land survey corner used, and California, Washington, Nevada and Oregon all impose filing duties on retracement work. Missouri does not. If you want your St. Louis survey to exist in a public record, you have to ask for it and pay the recording fee, and the time to raise it is when you sign the proposal, not five years later.
It is worth paying for. RSMo 60.653 requires the recorder to keep survey plats in a reproducible medium, index them by section, township and range and by subdivision or condominium name, and send a duplicate to the land survey program of the Missouri Department of Agriculture. It also gives the recorded plat real legal weight: "copies of survey plats shall be evidence in all courts of justice when properly certified under the hand and official seal of the recorder." A certified copy from the recorder walks into a boundary case on its own. A PDF in your email does not.
One honest caveat, and it is the same one that applies in Arkansas: recording preserves evidence of what a surveyor did on a given day. It is not an adjudication of your boundary and it does not settle a dispute by itself. What it buys you is a durable, court-ready record that survives a house fire, a firm closing, and the twenty years between you and the next argument about the fence.
Where a St. Louis survey record actually lives, and how to look before you spend
The metro has three separate records systems, not one, because the City of St. Louis has been an independent city since the 1876 separation from St. Louis County and is the only city in Missouri that runs its own county level offices, including its own Recorder of Deeds. Search the right one before you order anything.
| Where the land sits | Which office holds recorded plats | What to search by |
|---|---|---|
| City of St. Louis | St. Louis City Recorder of Deeds (city runs its own county level offices since 1876) | Address, subdivision name, city block number |
| St. Louis County, MO | St. Louis County Recorder of Deeds | Subdivision name, locator number, section, township and range |
| St. Charles, Jefferson, Franklin, Lincoln, Warren (MO) | That county's Recorder of Deeds | Subdivision name, section, township and range |
| Any Missouri county, as a statewide backstop | Land Survey Index, Land Survey Program, Missouri Department of Agriculture, Rolla | Section, township and range |
| Madison, St. Clair, Monroe and the rest of the Metro East (IL) | That Illinois county's Recorder | Subdivision name, parcel identification number, section, township and range |
Two practical notes. First, the statewide index exists because RSMo 60.653 makes the recorder send a duplicate of every recorded survey plat to the state land survey program, so the index is a copy of county records rather than a separate archive. Second, the Land Survey Program itself points out that records filed or recorded by a recorder of deeds and dated after December 31, 1969 have to be requested from the recorder where they were originally recorded. Use the state index to find out that a plat exists, then order the certified copy from the county. If nothing turns up, that is normal in Missouri and it is exactly what section 02 explains.
Missouri side versus Illinois side: what actually differs on your plat
These are not cosmetic differences. Two of them change what you receive for the same money, so read this before you approve a quote for a Metro East parcel.
| What you are checking | Missouri side | Illinois side (Metro East) |
|---|---|---|
| Rulebook | Missouri Standards for Property Boundary Surveys, 20 CSR 2030-16 | Minimum Standards of Practice, 68 Ill. Adm. Code 1270.56 |
| Monuments at your corners | Required at every exterior corner of the tract surveyed, with no client opt-out | Set at all accessible corners of the survey unless the client requests otherwise |
| Minimum semi-permanent marker | Iron pipe 3/4 in outside and 1/2 in inside diameter, or 1/2 in rod, at least 18 in long, capped | Iron bars or rods at least 1/2 in diameter by 24 in long |
| Cap marking | Cap inscribed with the license number of the surveyor in responsible charge or the company license number or name | Monuments set to a stable, distinctive location and set vertically wherever possible |
| Statement to look for near the seal | That the survey was executed in accordance with the Missouri Standards, plus the property type: Urban or Rural | The exact wording "This professional service conforms to the current Illinois minimum standards for a boundary survey" |
| Fences and occupation lines | Material variation between surveyed lines and lines of possession must be shown at all exterior corners | The character and location of evidence of possession or occupation along the perimeter must be shown |
| Improvements and easements | Located and drawn only when the client specifically asks, then tied to the boundary with at least three dimensions | Visible improvements, rights of way and easements shown when requested by the client |
| Where a corner cannot be monumented | A witness monument is set along a line of the survey or its prolongation | A witness corner or corners are set where physical impossibility prevents monumenting the corner |
The row that costs real money is the second one. On the Illinois side the standard lets the client waive monuments, which means a low quote for a Belleville or Edwardsville lot can legitimately come back with no pins in the ground. If you are surveying to build a fence, place an addition or settle an argument with a neighbor, put "set monuments at all accessible corners" in writing on the proposal. Missouri gives you no such waiver, which is one reason quotes on the two sides of the river are not directly comparable.
The St. Louis accuracy twist: a lot of this metro is legally Rural
Missouri grades survey precision into exactly two classes, and the test is legal status rather than how the neighborhood looks. In St. Louis County that produces a result most homeowners get backwards.
20 CSR 2030-16.020 defines Urban Property as any property located wholly or partly within the corporate limits of any municipality, or any commercial, industrial or multi-unit developmental property. Rural Property is defined in one line: any property that is not urban property. When the standards were revised, the old Suburban class was renamed Rural and the separate Rural accuracy class was removed altogether, so today there is no middle tier and no acreage test.
The precision that follows is set by 20 CSR 2030-16.040. On Urban property, the uncertainty due to random errors in any direction or distance shown on the plat may not exceed fifty parts per million or one tenth of a foot for distances under 2,000 feet, at the 68 percent confidence level. On Rural property the allowance doubles to one hundred parts per million or one tenth of a foot for distances under 1,000 feet.
Now apply it to St. Louis. Every parcel in the City of St. Louis sits inside municipal corporate limits, so the whole city is Urban property. St. Louis County is the opposite story: it contains 88 municipalities and still leaves roughly 300,000 residents in unincorporated territory. A single family lot in unincorporated west or south county is Rural property under the rule, however suburban the street looks, unless it happens to be commercial, industrial or multi-unit.
The actionable part is that Missouri makes the plat tell you. Among the required plat contents in 20 CSR 2030-16.030, the plat shall reference the property type (Urban or Rural). So take out your existing survey and read it. If it says Rural and you are about to build a fence, a garage or an addition against a tight setback, say so when you order the new work and buy the tighter standard deliberately rather than discovering the tolerance afterwards.
This is a genuinely different situation from the other side of the state. On the Kansas City side almost every suburban lot sits inside the corporate limits of a municipality and is therefore Urban by default. In St. Louis County that assumption fails for a large slice of the population. See the Missouri land surveyors page for how the same rules read statewide.
What to put in writing before you approve a St. Louis survey quote
Both states make several of the most useful deliverables optional, triggered only by a client request. That is where two quotes that look identical stop being identical.
- Monuments at every accessible corner. Mandatory in Missouri, waivable by the client in Illinois. Spell it out for any Metro East parcel.
- Improvements located. Under 20 CSR 2030-16.110 a Missouri surveyor locates the house, garage, slabs and footings only when specifically requested, and then ties them to the boundary with a minimum of three dimensions, parallel, perpendicular or radial to the lines. If you need to know how close the garage is to the line, ask for it by name.
- Easements shown. When asked, the surveyor shows by graphic representation all easements appearing on the recorded subdivision plat and all easements you hand over. Locating an easement on the ground is a further request again. Give the surveyor your recorded plat and title commitment up front so nothing is missed.
- Recording the finished plat. Not automatic in Missouri outside a new-parcel survey. Decide at proposal stage, and see recording a land survey for what it costs and which states force the issue.
- Subdivision monument timing. If you are splitting ground, the standard requires at least two permanent monuments for every four acres developed, waived when the survey creates no more than four lots, set before the plat is recorded or within twelve months of recording. Ask which applies before you agree a schedule with a builder. Our guide to splitting a parcel covers the sequence.
- The Missouri Coordinate System of 1983. Ask for it if the survey will feed engineering or GIS work. When requested, the surveyor must tie the corners to a second order or better geodetic control station and state the datum adjustment date, method and grid factor on the plat.
Land survey cost in St. Louis
Metro pricing for the Missouri and Illinois sides is broadly similar for residential work. The spread inside each band is driven by lot size, how old and how contradictory the record is, and how much fence, wall and driveway evidence has to be reconciled.
| Survey type | Typical St. Louis price | What moves the number |
|---|---|---|
| Residential boundary survey, city or suburban lot | $500 - $1,100 | Lot size, age of the subdivision plat, amount of occupation evidence to reconcile |
| Boundary survey, 1 to 5 acre metes and bounds parcel | $900 - $2,000 | Deed calls, timber and brush, distance to usable control |
| Mortgage or location survey for closing | $200 - $700 | Lender product only. No corners are set and the boundary is not independently determined |
| Boundary survey with improvements located | $600 - $1,300 | The add-on for locating structures, drives and easements under 16.110 |
| Topographic survey | $900 - $3,500 | Contour interval and site size. Commercial sites usually $1,500 to $3,500 |
| Elevation certificate | $400 - $900 | Floodplain work along the Mississippi, Missouri and Meramec and their creeks |
| ALTA/NSPS land title survey, commercial | $2,500 - $6,000+ | Acreage, Table A items requested, quality of the title documents supplied |
| Construction staking | $800 - $2,500 | Number of stakes, number of return visits, contractor schedule |
Recording fees are separate and are set by each recorder of deeds, so ask for the current figure when you decide to record. Compare quotes on the same scope: a Missouri quote already includes monuments at every corner, an Illinois quote may not, and a quote without improvements located is a different product from one with them. See the land survey cost guide and property survey cost by state for national context.
Where St. Louis surveyors get booked, and what drives the local job
| Area | What drives survey demand | Typical boundary survey |
|---|---|---|
| City of St. Louis: Tower Grove, Soulard, Benton Park, The Hill | Narrow nineteenth century platted lots where party walls, gangways and brick garages sit within inches of the line | $550 - $1,100 |
| Mid county: Clayton, University City, Webster Groves, Kirkwood, Maplewood | Teardown and rebuild permits, additions against tight setbacks, subdivision plats that predate modern monumentation | $550 - $1,100 |
| West and south county, much of it unincorporated: Chesterfield, Wildwood, Ballwin, Oakville | Larger lots, acreage splits, and the Urban versus Rural accuracy question from section 05 | $700 - $1,500 |
| St. Charles County: O'Fallon, St. Peters, Wentzville, Cottleville | The fastest growing county in the region, so new subdivision work, lot splits and builder staking | $600 - $1,200 |
| Jefferson and Franklin counties: Arnold, Festus, Washington, Union | Rural metes and bounds parcels, septic and well siting, timbered ground and long deed chains | $800 - $2,000 |
| Metro East, Illinois: Belleville, Edwardsville, O'Fallon IL, Columbia, Waterloo | Illinois plat of survey for permits and closings, plus Mississippi bottoms floodplain and levee district work | $550 - $1,200 |
Winter fieldwork is workable in the metro, but records turnaround, not weather, drives most of the timeline. Order three to four weeks ahead of a closing or permit date rather than paying a rush fee.
How to hire a St. Louis land surveyor without overpaying
1.
Work out which state and county
City of St. Louis, St. Louis County and the Metro East are three different records systems and, for Illinois, a different license entirely. Get this right before you call anyone.
2.
Search the record first
Check the right recorder of deeds and the statewide Land Survey Index. An existing plat, even an old one, cuts research time and can cut the quote.
3.
Write the scope down
Monuments at all corners, improvements located, easements shown, and whether you want the finished plat recorded. Each of these is optional somewhere in this metro.
4.
Compare three like-for-like quotes
Describe the parcel once in the form above and get up to three bids from license-verified, insured surveyors who actually work your county, usually within 24 hours.
St. Louis land survey questions
How much does a land survey cost in St. Louis?
A residential boundary survey in the St. Louis metro typically costs $500 to $1,100 for a city or suburban lot, and $900 to $2,000 for a 1 to 5 acre metes and bounds parcel. A mortgage or location survey for a closing runs $200 to $700 but sets no corners. A commercial ALTA/NSPS survey starts around $2,500. Lot size, the age of the record and the amount of fence evidence to reconcile drive the spread.
Does a land survey have to be recorded in Missouri?
Only when it creates a new parcel. RSMo 60.650 requires a surveyor who establishes, restores or reestablishes corners that create a new parcel of land to file the survey with the recorder of deeds within sixty days after certification. An ordinary retracement of an existing lot carries no filing duty, so most St. Louis residential surveys are never recorded unless the client asks and pays.
Where can I find my property survey in St. Louis County?
Start with the St. Louis County Recorder of Deeds and search by subdivision name, locator number, or section, township and range. If the property is inside the City of St. Louis, use the City Recorder of Deeds instead, because the city has run its own county level offices since 1876. The statewide Land Survey Index run by the Missouri Department of Agriculture is a useful second check.
Can a Missouri surveyor work on the Illinois side of St. Louis?
Not without an Illinois license. The license has to match the state the land sits in, not the state the office sits in, so a Missouri Professional Land Surveyor cannot seal a plat of survey in Belleville or Edwardsville unless someone in responsible charge is licensed by the Illinois Department of Financial and Professional Regulation. Many St. Louis firms hold both. Verify before you sign.
Is my St. Louis lot Urban or Rural for survey accuracy?
It depends on municipal limits, not on how the street looks. Missouri defines Urban Property as any property wholly or partly inside the corporate limits of a municipality, or any commercial, industrial or multi-unit development. Everything else is Rural. All of the City of St. Louis is Urban, but a single family lot in unincorporated St. Louis County is Rural and gets the looser 100 ppm standard.
How long does a land survey take in St. Louis?
Plan on two to four weeks from order to sealed plat for a residential boundary survey, and longer for a large or badly documented parcel. Records research is usually the slow part, not field work, because the surveyor has to pull deeds, subdivision plats and prior surveys from the right one of three separate records systems before a crew is scheduled.
Do I need a survey to build a fence in St. Louis?
Most municipal permit desks in the metro will accept a current survey or plat showing the fence line, and several require one. More importantly, a fence set from a guess is the single most common cause of a boundary argument here, and moving one is far more expensive than a $500 to $1,100 survey. Order a boundary survey with monuments set at every corner.
What is the difference between a plat of survey and a boundary survey in Illinois?
They are mostly the same product under different names. Illinois usage calls the sealed drawing of one parcel a plat of survey, and the Metro East permit counters ask for it by that name. It must carry the statement that the professional service conforms to the current Illinois minimum standards for a boundary survey. In Missouri the same deliverable is ordered as a boundary survey.
