Survey Markers & Monuments in Florida: Types, Laws & How to Find Them
Quick Answer
Survey markers (also called monuments, pins, or stakes) are physical objects placed by licensed surveyors to mark property corners and boundary lines. In Florida, molesting a survey monument, or defacing or destroying a recorded map or plat, is a second-degree misdemeanor under Florida Statute 177.121, punishable as provided in Florida Statutes 775.082 and 775.083.
What Are Survey Markers?
Survey markers are permanent physical objects set by licensed Professional Surveyors and Mappers (PSMs) to identify exact property corners, boundary lines, and reference points. They are the physical proof of where your property begins and ends under Florida law.
When a surveyor completes a boundary survey, they set markers at each corner of the property and at any angle points along the boundary. These markers tie directly to the legal description in your deed and the recorded plat.
Survey markers serve as evidence of the boundary and are referenced in legal disputes, fence installations, construction setback compliance, and property transactions.
Types of Survey Markers in Florida
Florida surveyors use several types of markers depending on the terrain, permanence requirements, and local conditions:
| Marker Type | Material | Typical Use | Permanence |
|---|---|---|---|
| Iron Rod & Cap | 5/8" iron rebar with aluminum cap | Most residential property corners | Permanent (decades) |
| Concrete Monument | 4"x4" concrete post with brass disk | Section corners, government survey points | Permanent (50+ years) |
| Iron Pipe | Iron pipe (3/4" to 2") | Older surveys, subdivision corners | Permanent |
| Nail & Disk | Nail in pavement with stamped washer | Right-of-way lines, road intersections | Semi-permanent |
| PK Nail | Large-headed masonry nail | Temporary construction points | Temporary |
| Wood Stakes & Flagging | Painted wooden stakes with ribbon | Construction layout, temporary marking | Temporary (weeks) |
The aluminum or plastic cap on top of an iron rod is stamped with the surveyor's name, license number, and often the date. This cap is how you verify who set the marker and which survey it belongs to. Under Florida's Standards of Practice (Chapter 5J-17), the surveyor's registration number must appear on all permanent markers.
Florida Law on Removing Survey Markers
Florida Statute 177.121 — Molesting a Monument or Defacing a Map or Plat
Survey monuments and recorded plats are protected under Florida law. Under Florida Statute 177.121, it is a misdemeanor of the second degree for any person to molest any monument established under Chapter 177, or to deface or destroy any map or plat placed on public record — punishable as provided in Florida Statutes 775.082 and 775.083.
Property owners, contractors, landscapers, and fence installers should not remove, disturb, or alter survey monuments. If a monument appears damaged, missing, or in conflict with planned construction, contact a Florida-licensed Professional Surveyor and Mapper before proceeding rather than moving or removing it yourself.
Common ways markers get destroyed:
- Landscaping crews pulling up "metal stakes" they don't recognize
- Construction equipment grading over corner pins
- Fence installers removing markers that are "in the way"
- Homeowners pulling up rebar thinking it's construction debris
- Paving over nail-and-disk markers in driveways
If you find a survey marker on your property, do not remove it. If you need to build near one, a surveyor can reference it before construction and reset it afterward.
How to Find Your Survey Markers
If you want to locate your existing survey markers without hiring a surveyor:
- Check your survey plat or sketch: If you received a survey when you purchased your home, the plat shows the type and location of each marker (e.g., "F.I.R." = Found Iron Rod, "S.I.R." = Set Iron Rod).
- Use a metal detector: Most markers are iron or steel and can be found 2–6 inches below the surface. Start at the approximate corners shown on your plat.
- Look for caps at the surface: In some cases, the aluminum cap is visible at or just above ground level, especially in areas without heavy vegetation.
- Check fence corners and sidewalk edges: Markers are often near fence posts, sidewalk corners, or curb intersections.
- Search the county recorder's office: Recorded plats and surveys filed with the county recording office show marker positions.
If you cannot find your markers, a licensed surveyor can recover them using GPS coordinates and reference measurements from the original survey. This is quoted per project, and the number of corners that need locating is the main driver — recovering an intact marker is quick, while a corner that has been destroyed has to be re-established from the record, which is substantially more work. See our Florida survey cost guide for how that pricing is built.
What to Do If Markers Are Damaged or Missing
If your survey markers have been disturbed, destroyed, or cannot be found:
- Do not try to replace them yourself. Only a Florida-licensed PSM can legally set or reset survey markers.
- Contact a licensed surveyor to perform a boundary survey and reset the markers. The surveyor will research the original records, perform field measurements, and set new monuments at the correct positions.
- If a neighbor removed your markers: Document the situation and consult both a surveyor and an attorney. Intentional interference with a monument is a second-degree misdemeanor under F.S. 177.121, and you will still need a licensed surveyor to re-establish the corner.
- If construction destroyed the markers: The contractor may be liable for the cost of a new survey and marker replacement. Document the damage before any further work occurs.
Survey Markers vs. Survey Stakes
Survey markers (also called monuments) are permanent, set at property corners, and have legal significance. They are typically iron rods, pipes, or concrete monuments with surveyor identification.
Survey stakes are temporary wooden or plastic stakes used during construction staking. They mark building corners, grade elevations, utility locations, and other construction reference points. Stakes are expected to be removed or destroyed during construction.
The key difference: never remove a metal marker with a cap — that's a permanent survey monument protected by law. Wooden stakes with paint or flagging tape are temporary and can be removed after construction is complete.
Frequently Asked Questions
Is it illegal to remove survey markers in Florida?
Yes. Under Florida Statute 177.121, it is a second-degree misdemeanor to molest any monument established under Chapter 177, or to deface or destroy any map or plat placed on public record, punishable as provided in Florida Statutes 775.082 and 775.083. Beyond the legal exposure, replacing a destroyed monument requires hiring a licensed surveyor to re-establish the corner, so the practical cost falls on whoever disturbed it.
What do survey markers look like?
The most common survey marker in Florida is a 5/8-inch iron rebar with an aluminum cap stamped with the surveyor's name and license number. You may also find iron pipes, concrete monuments with brass disks, or nails with washers in paved areas. They are typically found at property corners, 2-6 inches below the surface.
How do I find survey markers on my property?
Check your survey plat or sketch for marker locations (labeled F.I.R., S.I.R., etc.). Use a metal detector near approximate property corners — most markers are iron and detectable at 2-6 inches depth. You can also search recorded plats at your county recorder's office, or hire a licensed surveyor for marker recovery, which is quoted per project based on how many corners need locating.
Can I build a fence on a survey marker?
You should not build directly on top of a survey marker. If a fence post needs to go near a marker location, have a surveyor reference the marker first. The surveyor can document its position so it can be recovered later. Building over or displacing a marker could violate Florida Statute 177.121.
How much does it cost to replace a survey marker in Florida?
Replacing survey markers generally requires a boundary survey, because the surveyor has to verify the correct position from the record before setting a new monument - and in Florida only a licensed PSM may do that. Recovering and re-exposing markers that still exist is a much smaller job than re-establishing corners that are gone, which is exactly why the two are priced differently and why both are quoted per project rather than from a price list.
What does F.I.R. and S.I.R. mean on a survey?
F.I.R. stands for "Found Iron Rod" — a marker that was already in place when the surveyor arrived. S.I.R. stands for "Set Iron Rod" — a new marker placed by the surveyor during the survey. Other common abbreviations: F.I.P. (Found Iron Pipe), S.C.M. (Set Concrete Monument), F.N.D. (Found Nail and Disk).
