Pennsylvania Land Surveying Law: Boundary Work and Local Plan Review

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

Quick answer

In Pennsylvania, use a licensed professional land surveyor for a boundary, tract perimeter, corner monument, boundary description, or easement location. If the project divides or develops land, identify the municipality's subdivision process first, because the survey is only one part of local plan approval.

Pennsylvania draws a line between two professional scopes

Section 2 of the Engineer, Land Surveyor and Geologist Registration Law defines professional land surveying to include locating or retracing property boundaries, setting or replacing boundary monuments, preparing deed descriptions, and locating rights-of-way and easements.

The same statutory definition distinguishes engineering land surveys and expressly places tract perimeter surveys with the professional land surveyor. If a civil-engineering firm offers a combined site package, ask which Pennsylvania PLS is responsible for the perimeter and boundary deliverable.

Local government controls the subdivision path

The Pennsylvania Municipalities Planning Code authorizes local subdivision and land-development regulation. That means a parcel split, lot-line revision, or development plan should start with the municipality and, where applicable, county planning office, not with an assumption that one statewide plat checklist will apply.

Ask the reviewing office which ordinance, plan type, certifications, review fees, and recording steps apply. Then give that answer to the surveyor so the proposal covers the intended approval rather than only a field survey.

The Pennsylvania Department of State license verification service is the official status check. Verify the PLS, then compare scopes for records, monuments, staking, plan review, and recording.

Can a Pennsylvania professional engineer establish my tract perimeter?

The registration law distinguishes engineering land surveys from professional land surveying and states that tract perimeter surveys are the function of the professional land surveyor.

Are Pennsylvania subdivision requirements statewide?

The Pennsylvania Municipalities Planning Code supplies the state framework, but municipalities and counties administer subdivision and land-development review. Confirm the local ordinance before fixing the survey scope.
