Land surveyors in Maryland: licensed Professional Land Surveyors, quoted
Land surveyors in Maryland are licensed by the Maryland State Board for Professional Land Surveyors, under the Maryland Department of Labor. Only a licensed Professional Land Surveyor can determine boundaries and seal a survey. Maryland is a rare two-tier state: it stopped issuing the limited Property Line Surveyor license in 1990, so almost every surveyor today is a full P.L.S. Watch for the cheap location drawing at settlement, which by regulation is not a boundary survey. A full boundary survey typically costs $600 to $2,000. Surveyors.io verifies every license against the state roster and returns up to three quotes within about 24 hours.

What a Maryland land surveyor license means, and how to check one
Maryland licenses land surveyors through the Maryland State Board for Professional Land Surveyors, part of the Division of Occupational and Professional Licensing within the Maryland Department of Labor. Practice is governed by the Business Occupations and Professions Article, Title 15 of the Annotated Code of Maryland, with the Board rules and Minimum Standards of Practice at COMAR Title 09, Subtitle 13 (the standards themselves at 09.13.06). The credential is Professional Land Surveyor, carrying the post-nominal P.L.S. Determining boundaries and setting monuments is licensed work; no builder, title company or lender can do it.
Verify any Maryland surveyor yourself through the Department of Labor public license search at labor.maryland.gov/pq, which covers every occupational and professional board including land surveyors. Search the name, confirm an active land surveyor license, and ask for the license number before you hire.
On Surveyors.io the check is done for you. We verify each surveyor's Maryland license against the state roster, keep a certificate of professional liability insurance on file, and pull a profile the moment a credential lapses. You are only matched with surveyors licensed and active in Maryland.
The Maryland hook: the frozen Property Line Surveyor tier, and the location drawing trap
Maryland is one of very few states with a two-tier surveyor license, and the history matters when you hire. The full license is the Professional Land Surveyor. A second, narrower license, the Property Line Surveyor, once allowed a limited practice focused on boundary and property-line work while excluding certain site-development design services. But by statute, on and after July 1, 1990 the Board may not issue any new Property Line Surveyor license. The surveyors who held that license in 1990 can keep renewing, but the pool is a small, shrinking grandfathered group, so virtually every surveyor a Maryland consumer hires today is a full Professional Land Surveyor.
The practical takeaway: when you compare quotes, you are almost always comparing full P.L.S. professionals, and you should confirm an active Professional Land Surveyor license rather than assuming. The distinction is worth knowing because the full license covers the site-development design work, such as grading, erosion and sediment control and stormwater plans, that a property-line-only license did not.
The Maryland trap to avoid is the location drawing, sometimes called a house location drawing or mortgage loan inspection. Lenders routinely order one at settlement because it is cheaper than a boundary survey, and by regulation it is not a boundary survey. Under COMAR 09.13.06, a location drawing exists only to locate and represent buildings and visible improvements, and every one must carry the disclaimer that a location drawing is not a boundary survey and cannot be relied upon to show where the property boundaries are. If you plan a fence, an addition or a pool, you need a full boundary survey by a licensed Professional Land Surveyor, not the location drawing.
Land survey cost in Maryland
Maryland runs above the national average, driven by the DC metro, dense Baltimore lots and Chesapeake waterfront work. These are market ranges, not fixed fees.
| Survey / product | Typical Maryland cost |
|---|---|
| Location drawing / mortgage inspection (NOT a boundary survey) | $400 - $700 |
| Full boundary survey, standard lot | $600 - $2,000 |
| Boundary survey, waterfront / disputed / rural parcel | $2,500 - $10,000+ |
| Topographic survey | $1,000 - $3,000 |
| ALTA/NSPS survey (commercial) | $2,000 - $6,000+ |
| Elevation certificate (coastal / flood) | $400 - $750 |
The location drawing is on this list only to warn you it is not a boundary survey. Full national context is in the land survey cost guide.
Where Maryland surveyors get booked, and what drives the local job
Surveyors.io matches at county level across all 24 Maryland jurisdictions. These are the metros where demand concentrates and the local factor behind each.
| Metro / region | What drives survey demand | Typical boundary survey |
|---|---|---|
| Baltimore City & Baltimore County | Dense infill, older urban lots, teardowns, fences and additions | $700 - $2,200 |
| Montgomery & Prince George's (DC suburbs) | DC-metro development pressure, high land values, additions and ADUs | $800 - $2,500 |
| Anne Arundel & Annapolis | Chesapeake Bay Critical Area rules and waterfront / riparian boundary work | $900 - $3,000+ |
| Eastern Shore (Talbot, Queen Anne's, Worcester / Ocean City) | Waterfront, Critical Area and flood-zone elevation certificates | $900 - $3,500+ |
| Frederick & exurban Maryland | Fast-growing residential, acreage and subdivision surveys | $700 - $2,200 |
The Chesapeake shoreline is the Maryland specialty case: the Critical Area program, flood zones and riparian lines stack survey-adjacent work on top of the boundary survey, which is why waterfront ranges run highest.
Maryland land survey questions
How much does a land survey cost in Maryland?
A full boundary survey in Maryland typically costs $600 to $2,000 for a standard lot, and $2,500 to $10,000 or more for waterfront, disputed or rural parcels. A location drawing runs $400 to $700 but is not a boundary survey. Maryland runs above the national average because of the DC metro, dense Baltimore lots and Chesapeake waterfront work.
What is the difference between a location drawing and a boundary survey in Maryland?
A location drawing is a cheaper product the lender orders at settlement to show where buildings sit. By COMAR regulation it carries a disclaimer that it is not a boundary survey and cannot be relied on to show where the property boundaries are. A full boundary survey by a licensed Professional Land Surveyor legally establishes your lines and sets monuments. Never build a fence off a location drawing.
What is a Property Line Surveyor in Maryland?
The Property Line Surveyor was a limited Maryland license for boundary and property-line work that excluded certain site-development design services. Maryland stopped issuing it on July 1, 1990, so only a small, shrinking grandfathered group still holds it. Almost every surveyor you hire in Maryland today is a full Professional Land Surveyor. Confirm an active P.L.S. license before you hire.
How do I verify a Maryland land surveyor is licensed?
Use the Maryland Department of Labor public license search at labor.maryland.gov/pq, confirm an active land surveyor license, and note the license number. Every surveyor on Surveyors.io has already been checked against the state roster and carries professional liability insurance on file.
Do you need a survey to buy a house in Maryland?
No law makes a full survey mandatory, and many buyers only receive a location drawing at settlement. But that drawing is not a boundary survey. If you plan to build near a line, resolve a dispute, or your parcel is waterfront in the Critical Area, order a full boundary survey by a licensed Maryland surveyor.
How long does a land survey take in Maryland?
Two to four weeks is common for a full boundary survey covering records research, field work and the sealed plat. Waterfront parcels in the Chesapeake Bay Critical Area, Eastern Shore flood work and old lots with ambiguous boundaries push it longer, so order early.
