Maryland Land Surveying Law: Two Licenses, One Scope Question

Updated September 2, 2026 · 3 min read · State Surveying Laws

Quick answer

Maryland licenses both professional land surveyors and property line surveyors. The distinction matters because the statutory scopes differ. Verify the individual's credential, confirm that it covers the requested boundary, plat, topographic, or design work, and require the written scope to identify the signed and sealed deliverable.

Maryland's unusual distinction changes hiring

Business Occupations and Professions section 15-101 defines both “practice land surveying” and “practice property line surveying.” Property line surveying is a narrower credential focused on locating and describing boundaries, easements, and rights-of-way. The broader professional land-surveying scope includes additional measurement, planning, subdivision, condominium, topographic, and design-coordination work described in the statute.

Do not decide from the business name. Compare the assignment with the two scopes in section 15-101, then ask which licensed individual will be responsible for the complete work.

Maryland regulates both individuals and business practice

Section 15-301 requires board licensure before an individual practices land surveying or property line surveying, subject to listed exceptions and supervised work. Maryland also uses permits for corporations and partnerships offering these services.

Before a licensee issues a surveying plan, plat, report, or specification to a client or submits it to a public authority, section 15-502 requires the licensee's name and seal. Ask to see exactly which document will carry that responsibility.

A surveyor can retrace records, locate monuments, and report the boundary evidence. If the parties dispute ownership or lost bounds, Maryland Real Property section 14-111 describes a circuit-court process and permits the court to appoint surveyors or other experts. It also penalizes willful damage or removal of qualifying survey markers on another's property.

The homeowner takeaway is not to start with adverse-possession theories. Preserve the markers, obtain a defensible survey, and seek legal advice if the disagreement remains.

Match the credential and deliverable

Use the two credential definitions in section 15-101 to match the licensed responsibility to the work, then make the resulting deliverable explicit.

Verify before relying

Use the Maryland State Board public query to check the person and credential. Use the Maryland land surveyor directory to locate firms, then compare written scopes rather than titles alone.

Frequently Asked Questions

Why does Maryland have two land-surveying credentials?

Maryland law separately defines a professional land surveyor and a licensed property line surveyor. Their authorized scopes are not identical, so verify the credential against the work you need.

Must Maryland surveying documents be sealed?

Business Occupations and Professions section 15-502 requires a licensee's name and seal before a surveying plan, plat, report, or specification is issued to a client or submitted to a public authority.

Can a Maryland surveyor decide a boundary dispute?

A surveyor can locate and document boundary evidence. Maryland Real Property section 14-111 provides a court process for establishing a disputed line or lost bounds. Legal strategy belongs with a Maryland attorney.
