A land survey does not always start with a measurement. Sometimes it starts with a stack of old deeds. If a survey company asks for more documents than you expected, there is usually a reason tied to how older neighborhoods hold their property history. This article looks at why that request happens, and what you can do to move the process along.
Why an Older Pittsburgh Property Can Require More Record Research
Pittsburgh has many neighborhoods with property lines that go back a hundred years or more. Some parcels were split, combined, or renamed several times before they reached their current form. Each change usually left behind a document, whether that is an old deed, a plan, or a court record.
A surveyor working on one of these properties often needs to trace that chain of documents back through time. This is not true of every property in the city. Some parcels have a short and simple history. But in older sections, the chain can run through several owners, several plans, and sometimes a change in how the parcel was described.
This kind of research is different from simply asking a property owner to hand over a folder of papers. A surveyor is not collecting documents at random. Each document adds a piece to how the property came to be described the way it is today. Before relying on any single record, the surveyor needs to understand where that record sits in the property’s full history.
The Deed May Point to Records You Do Not Have at Home
Your current deed is rarely the whole story. Deeds often reference earlier deeds, recorded plans, or other documents tied to the property. A line in the deed might mention a plan recorded decades ago, or a prior transfer that set the boundaries you have now.
When a surveyor spots one of these references, they may ask you for it directly, even if you have never seen the document before. That is not an unusual request. It simply means your own deed pointed toward something that is not sitting in your file at home.
In Pennsylvania, county-level deed records hold much of this information. Allegheny County’s Recorder of Deeds keeps records of transfers, plans, and related documents tied to properties in the county. A surveyor working on a property will often pull records from that office as part of putting together the full document trail. This step is about following where the deed points, not about walking you through how to locate your property lines. That topic is covered elsewhere.
When a Prior Plan or Survey Becomes Useful to the Surveyor
If your property was surveyed before, or if it sits inside a recorded subdivision plan, that document can be useful. It might show how the parcel was originally laid out, who prepared earlier work, and what measurements were used at the time.
That does not mean an old survey gets treated as current. A surveyor cannot just copy an old plan and call it done. The surveyor has to look at what that older document shows, compare it with other evidence, and decide how much weight it deserves for the current assignment.
Pennsylvania surveying standards specifically call for surveyors to seek out relevant information already in the client’s possession, including any prior surveys, along with research into public records. So when a surveyor asks whether you have an old survey tucked away somewhere, they are following a normal step in preparing the work, not making an unusual demand.
Why “I Only Have the Deed” May Not End the Research
Most property owners only have one or two documents on hand. That is normal. A deed is often the only document people keep after a purchase, and that is fine. It does not mean the research stops there.
Records connected to a property can live in more than one place. Pennsylvania’s State Archives holds historical Land Office records, including early surveys and land grants that go back well before modern recording systems existed. More recent, privately prepared surveys, when they were recorded, usually sit with the county instead.
If you only have the deed, that is a starting point, not a problem. The surveyor will look in other places for anything else connected to the property. Handing over what you have is a way of giving the surveyor a head start, not a task you are expected to finish on your own.
What to Gather Before Calling Survey Companies Near Me
Before you call survey companies near me, a little preparation can save time later. Gather what you already have, even if it seems incomplete:
- Your current deed
- Any older deeds you still have
- Previous surveys, if you kept a copy
- Recorded plans or other property documents in your files
- Documents you received during a purchase or refinance
- Basic details identifying the property and its municipality
You do not need to track down anything you don’t already have. Once the survey company looks over what you brought, they can tell you which additional records, if any, would actually help with your specific job.
More documents requested does not mean something is wrong with your property. Most of the time, it means the surveyor is putting together enough documentary evidence to do the work correctly the first time.
Frequently Asked Questions
Why do survey companies near me ask for old property documents?
Older records can hold information relevant to a surveyor’s research. In Pennsylvania, property information is often spread across deeds, recorded plans, surveys, and other public records.
Do I need to find every old document before hiring a survey company?
No. Bring what you already have. Ask the surveyor which other records, if any, would help with your specific job.
Can an old survey still be useful?
Yes. A prior survey can offer historical information. A surveyor will look at it alongside other evidence rather than treat it as a current survey on its own.
Where are older Pennsylvania land records kept?
It depends on the type and period of the record. Pennsylvania’s State Archives holds historical Land Office records. Deeds transferring private property are kept at the county Recorder of Deeds.
Why might my deed lead a surveyor to another document?
A deed can reference earlier deeds, recorded plans, or other documents connected to the property’s history. Those references can prompt more research.
