Iowa Land Surveying Laws: A Guide for Property Owners
Iowa property owners encounter land surveys in many contexts: buying or selling a home, building a fence, dividing a farm parcel, or resolving a boundary dispute with a neighbor. Understanding the laws that govern land surveying in Iowa helps you protect your property rights, avoid costly errors, and work effectively with licensed surveyors. This guide covers the key statutes and practical implications every Iowa property owner should understand.
Iowa Code Chapter 542B: The Foundation of Surveying Law
Iowa Code Chapter 542B is the primary statute governing the practice of land surveying in Iowa. It defines who may legally perform surveys, establishes the licensing process, and sets standards for professional conduct.
Key provisions property owners should know:
- Only a licensed Professional Land Surveyor (PLS) may establish or re-establish property boundaries, set monuments, or prepare plats of survey in Iowa
- The Iowa Engineering and Land Surveying Examining Board licenses and regulates all Iowa PLSs
- Surveyors must satisfy education requirements, complete supervised field experience, and pass both national and state examinations to earn an Iowa PLS license
- Disciplinary actions against licensed surveyors are handled by the Board and are part of the public record
The practical implication for property owners: if someone locates your property corners but does not hold a current Iowa PLS license, that work carries no legal standing.

What a PLS Does When Performing a Survey
When you hire a licensed Iowa PLS to survey your property, they carry out a process that combines legal research and field work. Understanding the steps helps you set realistic expectations for timeline and cost.
The research phase comes first. The surveyor pulls deed records from the county recorder, reviews subdivision plats filed at the county, and locates any prior surveys affecting your parcel. For rural parcels, the surveyor researches original General Land Office (GLO) field notes from the Iowa government surveys conducted in the 1800s. These original notes document where government surveyors established section corners and quarter-section corners across the PLSS grid.
The field phase follows. The surveyor locates existing monuments, typically iron pins, concrete monuments, or brass caps set at property corners by previous surveyors. They use measurements tied to known section corners and recorded plat data to verify existing monument positions or establish new ones where prior monuments are missing or disturbed.
The deliverable is a certified plat of survey, signed and sealed by the Iowa PLS, showing the boundary locations, dimensions, and monument descriptions. This document is the legal record of where your property lines sit on the ground.
Iowa Code Chapter 355: Subdivision Platting
Iowa Code Chapter 355 governs the platting and recording of subdivided land in Iowa. If you want to divide property into two or more parcels for sale or separate development, this law applies to you.
Key requirements under Chapter 355:
- A plat of subdivision must be prepared by a licensed Iowa PLS
- The plat must meet technical requirements for dimensions, bearings, monument descriptions, and lot numbering
- The plat must be certified by the PLS with their seal and signature
- The plat must be reviewed and approved by the county or municipal authority before it can be recorded
- Lots within an unrecorded plat generally cannot be legally conveyed until recording is complete
Subdivision platting comes up most often when farm landowners want to split a parcel for a family member, when rural acreage is being developed into residential lots, or when an estate must divide property among heirs. The county recorder's office is the final filing location after all approvals are obtained.
Iowa's Public Land Survey System
Iowa property descriptions rely heavily on the Public Land Survey System (PLSS), which divides the state into a grid of townships and ranges, each further divided into 36 sections of approximately 640 acres. Most Iowa deeds describe property by reference to PLSS units, such as the “Northeast Quarter of Section 12, Township 80 North, Range 6 West.”
This system dates to the federal surveys conducted across Iowa from the 1830s through the 1850s by the General Land Office. Original GLO surveyors set section corners and quarter-section corners across the state, and their field notes document those original locations. Iowa PLSs use GLO field notes as primary source material when re-establishing boundaries on rural parcels where corners have been lost or disturbed over the intervening 150-plus years.
For property owners, the PLSS reference means your deed may look unfamiliar compared to deeds in subdivided urban neighborhoods that use lot-and-block descriptions. Both systems are legally valid. The surveyor translates the legal description into physical monuments on the ground.
Boundary Disputes and the Legal Process in Iowa
When neighbors disagree about where a property line falls, Iowa law provides a defined path for resolution.
Step 1: Commission a Survey
The first step in any Iowa boundary dispute is hiring a licensed Iowa PLS to conduct a boundary survey. The PLS researches the recorded deed and plat record, reviews neighboring parcel surveys, and conducts field work to establish where the boundary legally sits. The resulting certified plat is the foundation for any further action.
Step 2: Seek Agreement
If both parties accept the survey findings, a boundary line agreement can be drafted, signed by both owners, and recorded with the county recorder. This permanently resolves the boundary question and creates a recorded document that follows the property through future transactions.
Step 3: Litigation
If neighbors cannot agree after a survey, the dispute may require a court action to quiet title or establish the boundary by judgment. Iowa courts treat a certified PLS survey as authoritative evidence of boundary location. Some Iowa surveyors offer expert witness services and can testify to the legal basis for their boundary determinations.
Survey Monument Requirements in Iowa
Iowa Code Chapter 542B requires that surveyors set durable physical monuments at property corners when performing boundary surveys. These monuments are typically iron pins or pipes, concrete monuments, or brass caps set in rock or concrete. The surveyor must file a plat or record of survey with the county recorder documenting the monument locations, descriptions, and the basis for the boundary determination.
This filing requirement matters for property owners because it creates a public record. Future surveyors working on your property or neighboring properties can research your county recorder's records and find prior surveys, reducing the cost and time required to establish boundaries again in the future.
Iowa Code Chapter 359A: Partition Fences
Iowa Code Chapter 359A governs partition fences between adjoining landowners. Iowa uses a fence viewer (also called a fence commissioner) system administered through county boards of supervisors. Adjacent landowners generally share fence maintenance costs equally under this system.
The fence viewer system is distinct from boundary surveying, but the two overlap when the location of the fence line is uncertain. If neighbors disagree about where the boundary sits before resolving who owes what for a shared fence, a PLS survey is the legal tool to establish the line. For more on Iowa fence law and when a survey is needed before building, see our article on building a fence in Iowa.
Surveyor Liability and What a Certified Survey Means
An Iowa PLS who performs a boundary survey is held to professional standards of care. If a surveyor makes an error that causes measurable harm, such as placing a boundary incorrectly and causing a client to build in the wrong location, the surveyor can face professional discipline from the Iowa Engineering and Land Surveying Examining Board and civil liability for damages.
For property owners, this professional accountability is one reason why hiring a licensed PLS matters. The PLS seal and signature on a survey plat represent a legal certification that the work meets Iowa professional standards. A certified Iowa survey is not just a drawing. It is a legal document that can be recorded, relied upon in court, and used by title companies for insurance purposes.
