Property Surveys, Boundary Lines, and Encroachments
RETURN TO BLOG
A tax map, online GIS line, fence or mowing pattern is not a licensed boundary opinion. Buyers and sellers need to understand the difference between a recorded plat, lender location drawing and boundary survey before assuming where a driveway, shed, pier, septic area or tree sits.
Large and irregular Southern Maryland parcels often combine old deeds, subdivision plats, private easements, wooded corners and improvements added over decades. Calvert County GIS is useful for orientation, but a Maryland-licensed surveyor controls professional boundary work. Title counsel determines the legal effect of recorded documents and any discovered encroachment.
Dawn’s rule: Separate verified facts from assumptions. Then send each unresolved question to the professional or agency that controls the answer. A good contract strategy does not blur those roles.
Start with the property-specific question
A tax map, online GIS line, fence or mowing pattern is not a licensed boundary opinion. Buyers and sellers need to understand the difference between a recorded plat, lender location drawing and boundary survey before assuming where a driveway, shed, pier, septic area or tree sits. 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.
Large and irregular Southern Maryland parcels often combine old deeds, subdivision plats, private easements, wooded corners and improvements added over decades. Calvert County GIS is useful for orientation, but a Maryland-licensed surveyor controls professional boundary work. Title counsel determines the legal effect of recorded documents and any discovered encroachment. 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, survey, easement and right-of-way instrument
- Prior boundary survey, location drawing, stakeout or improvement location certificate
- Title commitment and exception documents affecting access or use
- Permit site plans for additions, pools, sheds, fences, septic systems and driveways
- Written neighbor agreements, maintenance arrangements or encroachment licenses
- Photographs and measurements of fences, buildings, walls, trees, utilities and driveway use
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
- A fence changes direction before reaching the apparent rear corner
- A shed, pool deck, retaining wall or driveway sits close to an assumed line
- The deed references an old plat that no one has located
- Neighbors share a driveway or waterfront access without a clear written agreement
- GIS acreage or line placement conflicts with the deed or field evidence
- A buyer plans a future addition based only on an online map
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.
A practical buyer checklist
- Step 1: Read the title exceptions and obtain the referenced instruments. Put the result in the transaction file and decide whether it changes affordability, intended use or the offer.
- Step 2: Ask the surveyor which product will answer the buyer’s actual question. Put the result in the transaction file and decide whether it changes affordability, intended use or the offer.
- Step 3: Walk the boundaries when practical and photograph visible occupation lines. Put the result in the transaction file and decide whether it changes affordability, intended use or the offer.
- Step 4: Compare proposed uses with setbacks, easements, septic reserve areas and Critical Area limits. Put the result in the transaction file and decide whether it changes affordability, intended use or the offer.
- Step 5: Send any discrepancy to the title company and attorney before the contract deadline. Put the result in the transaction file and decide whether it changes affordability, intended use or the offer.
- Step 6: Do not move a fence or confront a neighbor until the boundary and legal rights are verified. 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
- Seller action 1: Locate prior surveys and the recorded plat before listing. Early documentation protects credibility and gives the seller more choices.
- Seller action 2: Disclose known disputes, shared uses or inconsistent occupation accurately. Early documentation protects credibility and gives the seller more choices.
- Seller action 3: Avoid marketing acreage or waterfront rights beyond documented records. Early documentation protects credibility and gives the seller more choices.
- Seller action 4: Resolve movable personal-property items and identify permanent improvements. Early documentation protects credibility and gives the seller more choices.
- Seller action 5: Obtain legal advice before signing a boundary or maintenance agreement. Early documentation protects credibility and gives the seller more choices.
- Seller action 6: Price and negotiate with the real effect of an encroachment rather than its emotional meaning. 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
| Area | Possible effect |
|---|---|
| Use | boundaries and easements can limit additions, fences, pools, access and maintenance. |
| Financing | lenders and title insurers may require resolution or an acceptable survey product. |
| Insurance | liability can arise from shared access or improvements on another parcel. |
| Appraisal | usable site area and adverse encroachments can affect market reaction. |
| Title | recorded rights and physical occupation must be reconciled for insurable ownership. |
| Seller net | survey, legal work, relocation or agreements can add cost. |
| Resale | unresolved line questions return with the next buyer and may narrow the market. |
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?
| Professional | What that professional should answer |
|---|---|
| Dawn Riley and the real estate team | Organize documents, identify contract deadlines, coordinate questions, compare offer terms and keep advice from each licensed professional in the correct lane. |
| Title company or real estate attorney | Review recorded instruments, ownership, liens, deed language, settlement charges and legal questions. Only an attorney should give legal advice. |
| Lender and appraiser | Decide loan eligibility, underwriting treatment, valuation requirements and documentation. A real estate agent cannot approve financing or direct an appraisal result. |
| Inspector, engineer or specialty contractor | Evaluate physical conditions within the professional scope and explain repair options. A general home inspection does not replace engineering or environmental review. |
| Insurance producer | Confirm whether coverage is available, what it costs, which exclusions apply and what underwriting records are required. |
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 loves a yard that appears to extend to a split-rail fence. The recorded plat and a new boundary survey place part of the fence and a garden on the neighboring parcel. Dawn does not call the fence the legal line or accuse either owner. She sends the survey and title documents to counsel, prices the impact on intended use and negotiates only after the buyer understands the options.
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
Dawn starts with the client’s intended use: maintain the existing yard, add a structure, secure access or simply obtain insurable title. The survey scope must answer that question. If an encroachment exists, the agreement should define whether it will be removed, licensed, insured over, accepted or resolved another way, subject to lender, title and legal approval.

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 tax map, online GIS line, fence or mowing pattern is not a licensed boundary opinion. Buyers and sellers need to understand the difference between a recorded plat, lender location drawing and boundary survey before assuming where a driveway, shed, pier, septic area or tree sits. 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.
Frequently Asked Questions
No. GIS is valuable for research and orientation, but mapped parcel lines are not a licensed boundary determination. Use a Maryland-licensed surveyor for a professional opinion.
Not automatically. A fence may have been placed for convenience or may be inaccurate. A surveyor should locate the boundary, and an attorney should explain any legal claim or agreement.
A location drawing generally shows improvements in relation to apparent boundaries for a limited purpose. A boundary survey is designed to establish or reestablish property lines under professional standards. Ask the surveyor which is appropriate.
A survey can plot easements when the documents and scope permit, but title work identifies recorded instruments. The surveyor and title professional should review the same source records.
It is a physical improvement or use crossing a boundary or burdening another property right. Its seriousness depends on location, size, use, documents, title and legal remedies.
Coverage depends on the policy, survey, exceptions and underwriting. The title company must provide the property-specific answer in writing.
Order the level of survey needed for the intended use and risk. A rural parcel, shared access, close improvements or future construction may justify more than a basic lender product.
Only after verifying the line, permits, association rules and legal rights. A rushed relocation without survey control can create a new dispute.
Both matter. A septic area must lie within the applicable property rights and satisfy health requirements. Review the survey and health records together.
The buyer decides whether the practical effect is acceptable, while the lender, title insurer and attorney decide their requirements. Dawn coordinates the evidence and contract response.
