Start with the Pennsylvania License Database
The single most important step when hiring a land surveyor in Pennsylvania is verifying their license. Pennsylvania requires all persons performing boundary surveys to be licensed as a professional land surveyor by the State Registration Board for Professional Engineers, Land Surveyors and Geologists (PELSB). The license database is free and publicly available at pals.pa.gov.
To use it, go to pals.pa.gov and select the license lookup option. Search by the surveyor's name or license number. The results show whether the license is current, when it expires, and whether any disciplinary actions are on record. This check takes less than two minutes. Do not skip it.
Pennsylvania licenses must be renewed periodically, and surveyors must complete continuing education requirements to maintain licensure. An expired license means the surveyor is not currently authorized to practice. A disciplinary record is a serious red flag that deserves investigation before you commit to hiring.
Use the PCLS Member Directory
The Pennsylvania Council of Land Surveyors (PCLS) at pcls.net maintains a member directory of professional surveying firms across the state. PCLS membership is voluntary, but member firms have agreed to professional standards and are actively participating in the Pennsylvania surveying community. The directory lets you search by county or region to find firms near your property.
PCLS members stay current on changes to Pennsylvania surveying law, FEMA flood mapping updates, PELSB licensing requirements, and evolving survey standards. Membership is not a substitute for verifying the individual's license at pals.pa.gov, but it is a positive indicator of professional engagement.
Ask About Local Experience
Pennsylvania's diverse geography and deed history means that local experience matters. A firm that regularly works in Philadelphia has deep familiarity with the City Archives, the Recorder of Deeds at Philadelphia City Hall, and the complexities of row house lot histories. A firm working in Allegheny County knows how to navigate the steep terrain of Pittsburgh's hillside neighborhoods and the mineral rights issues common in western PA coal country.
When you contact a surveyor, ask how many surveys they have completed in your specific county or municipality. Ask whether they are familiar with the county GIS portal and the local recorder of deeds records. A surveyor who regularly works in your area will have existing relationships, prior survey records to reference, and familiarity with local monumentation practices that speed up the work.
What to Ask Before You Hire
When you call a surveying firm for a quote, have your deed description, county parcel ID, and approximate property dimensions ready. Then ask these specific questions.
Ask for a firm written quote based on a review of your deed. Any surveyor who gives you a price without reviewing your deed is estimating without information. A review of your deed and the parcel information typically takes a day or two, and most reputable firms will do it before quoting.
Ask what the quote includes. Does it include monument placement or replacement? Does it include a signed and sealed plat? Are there additional fees for title research, extra corners, or rush delivery?
Ask for the expected timeline from start to completed plat. Standard residential boundary surveys in Pennsylvania typically take two to four weeks. A firm that promises results in two days without good reason may be cutting corners.
Ask for references from recent clients in your area. A firm confident in their work should be able to provide contact information for recent survey customers.
Red Flags When Hiring a Pennsylvania Land Surveyor
Several warning signs indicate a surveyor may not be the right choice for your project.
An unlicensed provider is a clear disqualifier. Anyone who cannot provide a current Pennsylvania professional land surveyor license number should not be hired for boundary work. An unlicensed survey has no legal standing.
A verbal quote with no review of your deed is unreliable. Reputable surveyors do not price boundary surveys off the top of their heads.
No written contract is a problem. Before fieldwork begins, you should have a written agreement that describes the scope of work, the deliverables, the price, and the timeline. Oral agreements lead to disputes.
No sealed plat at the end is unacceptable. Any legitimate Pennsylvania boundary survey produces a document signed and stamped with the surveyor's PA license seal. If a provider tells you they will give you an informal sketch or a handwritten map, that is not a legal survey.
Regional Resources by Area
In Philadelphia and surrounding counties, surveyors regularly work with the Philadelphia City Archives, the Office of Property Assessment, and the Philadelphia Register of Deeds. For complex row house surveys, experience with colonial-era deed chains is important.
In Allegheny County, survey firms familiar with the Allegheny County GIS portal, the Department of Real Estate, and the county's online deed records at alleghenycounty.us have an advantage in completing research efficiently.
In the Lehigh Valley, Lehigh County and Northampton County both maintain GIS portals with parcel boundary data. This data is not legally binding but helps surveyors orient before fieldwork.
In Dauphin County and the Harrisburg area, the county assessment office and the Dauphin County GIS system provide useful background data. Properties near the Susquehanna River may also require FEMA flood map research.
In Luzerne and Lackawanna counties, flood exposure from the Susquehanna and its tributaries means many surveys in the Wyoming Valley come paired with elevation certificate requests. Surveyors in this region should be familiar with NFIP requirements and FEMA flood map procedures.
What Happens After You Hire a Surveyor
After you hire a licensed Pennsylvania surveyor and sign an agreement, the process generally unfolds in three stages. First, the surveyor researches your deed, searches the county recorder of deeds for prior surveys, and reviews adjoiners' deeds. Second, field crews visit your property to locate existing monuments and measure the boundaries. Third, the surveyor prepares the plat, reviews the results, signs and seals the document, and delivers it to you.
You may have questions during the process. A good surveyor will explain what they found and what it means in plain terms. If the survey reveals an encroachment, a gap in the deed history, or a boundary that does not match a fence line, you deserve a clear explanation before any decisions are made.
The completed plat is your legal record of the boundary survey. Keep it with your other property documents and provide a copy to your title insurer if applicable.
