Boundary Surveys, Fences, and Encroachments Before Closing

By Dawn Riley, Associate Broker, Realtor, Master Certified Negotiator (MCNE) and Pricing Strategy Advisor (PSA) | Published November 2, 2026

A fence is evidence that somebody once wanted a fence. It is not automatic proof of the legal boundary. Buyers and sellers should compare the deed, recorded plat, title exceptions and an appropriate survey before treating a mower line as a property right.

Calvert County parcels may include acreage, older plats, private access, waterfront edges, agricultural land and accessory structures. Online mapping is useful for orientation, but the county itself warns that mapped property lines are not survey grade and have no legal standing. The cheerful dotted line on a screen does not get to testify in court.

Start with the property-specific question

A fence is evidence that somebody once wanted a fence. It is not automatic proof of the legal boundary. Buyers and sellers should compare the deed, recorded plat, title exceptions and an appropriate survey before treating a mower line as a property right. That distinction matters because buyers and sellers often hear a shorthand answer and treat it as final. A listing description, seller memory, online map or contractor opinion can be useful, but none automatically controls title, financing, insurance, permitting or legal rights.

Calvert County parcels may include acreage, older plats, private access, waterfront edges, agricultural land and accessory structures. Online mapping is useful for orientation, but the county itself warns that mapped property lines are not survey grade and have no legal standing. The cheerful dotted line on a screen does not get to testify in court. Dawn begins by writing down the client’s intended use, the evidence already available and the deadline for a reliable answer. That prevents research from becoming an open-ended project and keeps the parties focused on what could change price, terms or willingness to proceed.

Records buyers and sellers should collect

Documents usually reveal more than reassurance. Collect the following records early, preserve the original file names and note the source and date. If a record is missing, label it missing. Do not replace it with an assumption.

• Current deed and every referenced plat or survey
• Title commitment and copies of easements, restrictions and rights-of-way
• Recent location drawing, boundary survey or ALTA product appropriate to the question
• Permits and site plans for fences, sheds, pools, additions and driveways
• Written neighbor agreements or licenses affecting use
• Photographs and measurements of visible fences, walls, structures and access routes

These records should be read together. A permit without a final inspection, a survey without the referenced easement, or an estimate without a defined scope can create false confidence. Dawn builds one shared checklist and tracks who requested each item, when it arrived and which professional still needs to review it.

Local warning signs that deserve a closer look

• The fence line and mapped parcel line visibly disagree
• A shed, pool, driveway or retaining wall sits close to the apparent boundary
• The deed references a plat or easement nobody has obtained
• A neighbor uses part of the property for parking, access or storage
• The seller relies on a tax map or phone app as the final boundary answer
• The buyer plans improvements near setbacks before obtaining a survey

A warning sign is not proof of a defect, denial or legal violation. It is a reason to slow down and ask a narrower question. The strongest due diligence says, “Here is what we observed, here is the controlling document or agency, and here is the answer we need before this date.”

In Calvert County, rural land, waterfront, private systems and community restrictions often overlap. One professional cannot answer every layer. A contractor may estimate a repair but cannot guarantee lender acceptance. A county employee may explain permits but not interpret a private contract. A Realtor can organize the transaction but does not replace legal, engineering, insurance or tax advice.

Verified rules and practical limits

• Maryland licenses professional land surveyors and property line surveyors through the Department of Labor
• Calvert County online mapped property lines are not survey-grade and do not have legal standing
• Different survey products answer different questions, so the buyer should tell the surveyor the intended use
• Title insurance exceptions and survey matters require review by the title company or Maryland attorney
• A fence permit or association approval does not by itself establish ownership of the land beneath the fence
• Encroachment remedies and adverse possession questions are legal matters

These are starting points, not a substitute for a property-specific decision. Programs, forms and underwriting requirements can change. Dawn verifies the current rule with the controlling professional and keeps the written answer with the transaction file.

A practical buyer checklist

1. Step 1: Tell the title company and surveyor about planned fences, pools, sheds or additions. Put the result in the transaction file and decide whether it changes affordability, intended use or the offer.
2. Step 2: Order the survey product that answers the actual boundary question. Put the result in the transaction file and decide whether it changes affordability, intended use or the offer.
3. Step 3: Compare survey findings with title exceptions and visible conditions. Put the result in the transaction file and decide whether it changes affordability, intended use or the offer.
4. Step 4: Obtain copies of every referenced easement or agreement. Put the result in the transaction file and decide whether it changes affordability, intended use or the offer.
5. Step 5: Send proposed improvements to the county and association before relying on feasibility. Put the result in the transaction file and decide whether it changes affordability, intended use or the offer.
6. Step 6: Resolve material encroachments through counsel before closing or accept them knowingly. Put the result in the transaction file and decide whether it changes affordability, intended use or the offer.

Buyers should prioritize questions that can end the purchase, change the monthly cost or make the planned use impossible. Cosmetic preferences can wait. Title, financing, insurance, safety, legal use and expensive physical conditions cannot. The contract should preserve enough time to receive real answers rather than merely submit requests.

A practical seller checklist

1. Seller action 1: Locate prior surveys, plats and improvement permits. Early documentation protects credibility and gives the seller more choices.
2. Seller action 2: Avoid advertising exact acreage or boundaries beyond reliable records. Early documentation protects credibility and gives the seller more choices.
3. Seller action 3: Disclose known disputes, encroachments and neighbor agreements. Early documentation protects credibility and gives the seller more choices.
4. Seller action 4: Move movable items away from disputed areas when appropriate. Early documentation protects credibility and gives the seller more choices.
5. Seller action 5: Give surveyors reasonable access and preserve corner markers. Early documentation protects credibility and gives the seller more choices.
6. Seller action 6: Discuss cure options with title and counsel before negotiating a deadline. Early documentation protects credibility and gives the seller more choices.

Sellers gain leverage by solving uncertainty before a buyer turns it into a worst-case estimate. That does not mean repairing everything or agreeing with every concern. It means describing the property accurately, producing records quickly and understanding the likely cost and timing of any real issue before negotiating.

How this issue can affect the transaction

Not every possible effect will apply. The purpose of the table is to prevent tunnel vision. A buyer may solve a physical concern and still have a lender problem. A seller may agree to a credit and still lack insurable title or carrier approval. Each lane must reach its own answer.

Who should answer each part?

Dawn’s job is to make sure the correct question reaches the correct professional before the relevant decision date. She can explain the Maryland contract process, organize evidence and negotiate terms. She will not present a guess as a legal, underwriting, engineering, appraisal, insurance or tax conclusion.

A realistic Southern Maryland transaction example

A Huntingtown buyer wants to fence the yard for dogs. The existing fence looks convenient, but the online map suggests one corner is several feet off. I do not choose between two imperfect clues. We order the appropriate survey, pull the plat and title documents, ask the county about setbacks and let counsel review any real encroachment. The buyer can decide before paying for a fence that might need a second career as firewood.

This example is illustrative, not a prediction. Property facts, contract language and professional decisions vary. What remains consistent is the method: identify the uncertainty, obtain the controlling evidence, calculate the effect and decide before leverage disappears.

How Dawn organizes the contract and negotiation strategy

I describe the observation without accusing a neighbor or promising a legal result. The contract strategy identifies the required document, access for the survey, deadline, acceptable cure and buyer option if the result is materially different. If an agreement is proposed, a Maryland attorney should draft or review it.

Her career includes 1,338+ sales and more than $532,653,786 in volume, with average sold-to-list statistics over 101%. Those numbers do not guarantee a result. They support a disciplined approach to pricing, documentation and negotiation.

Common mistakes to avoid

The first mistake is treating a verbal answer as a permanent fact. The second is asking the wrong professional to guarantee an outcome outside that person’s authority. The third is waiting until settlement week, when moving plans, rate locks and emotions make clear decisions harder.

Another mistake is assuming a credit cures everything. Money can address a known cost, but it does not create a permit, change a title right, make a lender approve the loan or force an insurer to issue coverage. The remedy must match the actual problem.

The Bottom Line

A fence is evidence that somebody once wanted a fence. It is not automatic proof of the legal boundary. Buyers and sellers should compare the deed, recorded plat, title exceptions and an appropriate survey before treating a mower line as a property right. Collect the records, identify the controlling authority, calculate the transaction impact and protect the deadline. Buyers deserve enough evidence to make an informed decision. Sellers deserve a strategy that does not discount the property simply because information was disorganized.
