The Short Answer
Iowa law does not require a survey to sell a residential property. There is no statewide statute that makes a survey a condition of closing a home sale. That said, surveys come up in Iowa real estate transactions more often than sellers expect, and knowing when one is likely to be requested can prevent closing delays and last-minute surprises.
What Iowa Law Requires at Closing
Iowa is a disclosure state. Sellers are required to disclose known material defects and conditions affecting the property, including boundary disputes, encroachments, or claims by neighboring owners that the seller is aware of. The disclosure obligation covers what you know, not what a survey might uncover.
A seller who knows of a fence line dispute or a structure that sits over the property line and says nothing risks legal exposure after closing. A survey done before listing surfaces these issues when there is still time to resolve them cleanly, before a buyer is under contract and the pressure to close is high.
When Lenders Request a Survey in Iowa
Even though Iowa law does not require a survey, the buyer's mortgage lender may ask for one. Common situations where this happens:
- The existing survey on file is more than 10 years old
- The legal description uses a PLSS metes and bounds description rather than a lot-and-block reference to a recorded plat
- The property is located in a rural area without a filed subdivision plat
- A recorded easement exists whose location on the ground is unclear
- An addition, garage, or outbuilding was constructed after the last survey
- The lender's underwriting guidelines require a current survey for properties above a certain loan amount
When a lender requests a survey and none has been done, the transaction may be delayed by one to three weeks while a licensed Iowa PLS completes the work. Having a current survey before listing eliminates this risk entirely.
When Title Companies Request a Survey in Iowa
Title companies issuing title insurance in Iowa do not always require a survey. Many will insure a standard residential transaction based on a recorded subdivision plat and a clean title search. However, title underwriters may require a survey in these circumstances:
- The property has an older deed with an irregular or unclear description
- There is a recorded easement whose physical location cannot be confirmed from documents alone
- Prior title insurance claims or boundary notes appear in the chain of title
- The property is unplatted or has never been surveyed
- A prior survey shows discrepancies or notes unresolved conflicts with adjacent parcels
In some cases, a title company will insure around a boundary uncertainty but exclude coverage for any loss arising from that uncertainty. Sellers who want to deliver clean, fully insured title to a buyer are better served by resolving these issues with a survey than by hoping an exclusion does not affect the deal.
The Difference Between a Survey Plat and a Title Search
These two tools are often confused in real estate transactions because both are associated with title insurance and closing. They address different questions.
A title search is conducted by an attorney or title company examiner who reviews recorded documents at the county recorder and courthouse. The search establishes the chain of ownership, identifies mortgages and liens, and locates recorded easements and covenants. It tells you who has claims against the property as a matter of law.
A survey plat is produced by a licensed Iowa PLS through a combination of records research and field measurement. It shows where the physical boundary lines of the property sit on the ground, where the corner monuments are located, and how structures and improvements relate to those lines. It tells you where your property ends and your neighbor's begins.
A clear title search does not mean your fence is on the right side of the line. A survey provides that answer.
When Sellers Proactively Order a Survey in Iowa
Some Iowa sellers choose to commission a survey before listing the property, even when not required. This makes sense in several situations:
Fence Encroachments
A fence installed by a prior owner may sit over the property line onto a neighboring parcel. Discovering this during a buyer's inspection is worse than finding it before listing. When a seller knows about an encroachment before the property goes on the market, they can address it on their own timeline.
Additions and Outbuildings
A garage, shed, deck, or addition built without a survey may encroach on a setback or a neighboring parcel. If the addition was permitted and built correctly, a survey confirms this and gives the buyer confidence. If it was not, the seller learns this before a buyer's inspector flags it.
Older Deeds with Vague Descriptions
Iowa farmland and older rural parcels sometimes carry deeds with PLSS descriptions that reference quarter sections or half sections of land. These descriptions are legally valid but can leave uncertainty about exactly where the boundary runs when corners have not been surveyed or re-established in decades. A survey tied to current GLO corner records resolves that uncertainty before it becomes a lender or title company issue.
Known Neighbor Disputes
If a boundary disagreement with a neighbor has been simmering, a seller who resolves it before listing avoids disclosing an open dispute to every buyer who makes an offer. A survey and a recorded boundary line agreement are far cleaner solutions than listing a property with a disclosed dispute attached to it.
Cost and Impact on the Sale
A standard residential boundary survey in Iowa typically runs $500 to $1,200 for a platted urban or suburban lot. Rural parcels and acreage properties, where the surveyor must research GLO field notes and locate section corner monuments, often cost $800 to $2,500 or more.
Compare that to carrying costs if a closing is delayed by two to four weeks while a survey is completed, or to the cost of renegotiating a purchase price after a buyer's inspector raises a boundary concern. Sellers who provide a current survey are also seen by some buyers as lower-risk, which can support a smoother negotiation.
Plot Plans vs. Full Boundary Surveys
Some Iowa mortgage lenders request a “plot plan” rather than a full boundary survey. A plot plan is a simplified drawing showing the property's approximate shape and the location of major improvements relative to the lot lines. It is less detailed and less expensive than a certified boundary survey, but it also provides less legal protection.
If a lender accepts a plot plan, it satisfies the lender's requirement but does not establish where boundary lines legally sit. If there is any concern about the boundary, a full survey from a licensed Iowa PLS is the more protective choice for both the seller and the buyer.
