Missouri Fence Law and When a Survey Matters
Missouri does not require a land survey before building a fence. There is no state statute that makes a survey a legal prerequisite to fence construction. But that short answer misses the practical reality for many Missouri property owners. If you are not certain where your property line is, building first and surveying later is a gamble that can turn into an expensive dispute.
Here is what Missouri law says about fences, when a survey is the right call before you build, and how to protect yourself whether you are in Kansas City, a rural Ozark county, or anywhere in between.
Missouri's Partition Fence Law: RSMo Chapter 272
Missouri Revised Statutes Chapter 272 is the state's partition fence statute. It governs fences that sit on or along a boundary line between two adjoining properties. The key principles under Chapter 272 are:
- Adjoining landowners in Missouri are jointly responsible for maintaining a legal partition fence along their shared boundary line
- Each party is responsible for a portion of the fence, typically divided between the two corners based on a line running diagonally across the shared boundary
- Either party can call in county fence viewers if there is a dispute about fence placement, condition, or the cost-sharing arrangement
- Fence viewers in Missouri are typically the county commissioners of the county where the property is located
Chapter 272 applies to rural agricultural land situations as well as residential properties. The law has deep roots in Missouri's farming history, and many rural landowners rely on it when disputes arise about old fence lines between fields.
The Critical Link Between Fence Viewers and Surveys
The fence viewer process under Chapter 272 depends on knowing where the property line actually is. Fence viewers can determine how costs should be split and what condition the fence should be in, but their authority rests on the actual legal boundary. If you and your neighbor disagree about where that boundary falls, the fence viewers cannot resolve the dispute on their own. A boundary survey is the tool that establishes the legal line they need as a reference.
In practice, this means that many partition fence disputes in Missouri follow a sequence: a disagreement arises, one or both parties hire a licensed Professional Land Surveyor to establish the boundary, and then the fence viewer process or a negotiated agreement follows. Skipping the survey and going straight to fence viewers often just delays the inevitable if the line itself is in dispute.
When You Probably Do Need a Survey Before Building a Fence in Missouri
You Are Not Sure Where Your Property Line Is
This is the most common reason Missouri property owners order a boundary survey before fence construction. If you cannot find the iron pins marking your corners, if your deed description references landmarks that have changed, or if you have never confirmed the location of your lot's edges, you are guessing at the line. Fences built in the wrong location have to be moved, and moving a fence after the fact costs far more than a survey would have cost upfront.
Your Neighbor Disagrees About the Line
If there is any disagreement between you and your neighbor about where the boundary falls, get a survey before placing a single post. Building over a disputed line opens you to a demand for removal, potential litigation, and costs that dwarf the price of the original survey. A survey from a licensed Missouri PLS gives both parties a documented, legally defensible answer.
You Are in an Area with Old Fences Already in Place
Rural Missouri has thousands of miles of old fence lines that were placed based on handshake agreements, approximate measurements, or outright guesses decades ago. A fence line that has been in the wrong location for many years can complicate any new boundary determination. Missouri recognizes adverse possession, which means a long-standing misplaced fence, in some circumstances, can eventually affect legal title. If old fences on your property do not match what you think the deed lines show, a survey before building a new fence is an investment in clarity.
You Are Near a Setback Line
Missouri cities, counties, and municipalities impose setback requirements that dictate how close a fence can be to a property line or to the street right-of-way. If you are in any incorporated Missouri community, check local ordinances before building. If your planned fence location is within a few feet of the required setback, a survey confirms whether you are in compliance before you spend money on materials.
Missouri Cities and Local Fence Ordinances
Missouri has no statewide fence height or setback law that applies uniformly to all residential properties. Local ordinances control. Some examples:
- Kansas City requires building permits for most fences over a certain height and imposes setback requirements from street-facing property lines
- St. Louis City has detailed fence regulations that vary by zoning district
- Springfield, Columbia, and Jefferson City all have local fence ordinances with permit requirements
- Many smaller Missouri municipalities follow their county's zoning ordinances
Before building any fence in an incorporated Missouri community, check with the local planning or building department for permit requirements, height limits, and setback rules. Many Missouri municipalities require you to show the property line location as part of the fence permit application, which means a survey may effectively be required even if state law does not mandate one.
Rural Missouri: Fence Lines and Adverse Possession Risk
In rural Missouri, the relationship between fences and property lines is complicated by decades of informal land management. Many farming communities have fence lines that follow field edges rather than deed lines, and some have been in place long enough that adverse possession claims are theoretically possible if the occupancy was open, continuous, exclusive, and hostile to the owner's title for Missouri's ten-year statutory period.
If you are purchasing rural Missouri land with existing fence lines, a boundary survey before closing gives you a clear picture of whether those fences align with the deed description. If they do not, you can address the discrepancy before it becomes your problem as the new owner.
Practical Advice: Survey First, Then Build
The cost of a boundary survey in Missouri, typically $400 to $900 for a residential lot, is small compared to the cost of moving a fence that was built in the wrong location. For rural parcels, the calculation is similar. Survey cost scales with acreage, but so does the financial risk of a misplaced fence.
If your neighbor is willing to share the cost, even better. A shared survey splits the expense and gives both parties a document they both recognize as authoritative. That is often the fastest path to getting a fence built without a dispute.
Find a Missouri Surveyor Before You Build
If you have any doubt about where your property line falls, get a survey before the first post goes in. Use our Missouri land surveyor directory to find licensed PLSs in your county who can establish your boundary and give you the confidence to build correctly the first time.
