A survey doesn’t start when the crew arrives on site. It starts with research. A licensed surveyor reviews documents before a single measurement is taken. That research shapes every decision made in the field. In Tampa, where older subdivisions sit next to newer developments and county records span decades, the document review is where survey accuracy starts. This article covers which documents get reviewed and why each one matters.

The Property Deed and Legal Description

The deed is the first document a licensed surveyor reads. It contains the legal description of the property. That description tells the surveyor where the boundaries are supposed to be.

Legal descriptions come in two main forms. Metes and bounds descriptions define the boundary using directions and distances. Lot and block descriptions reference a recorded subdivision plat. Both types need careful reading.

Older deeds sometimes have errors. A description might reference a monument that no longer exists. Two adjacent deeds might overlap. That creates a conflict the surveyor has to find and resolve.

Reading the deed before fieldwork tells the surveyor what to measure and where problems may be hiding. Without it, the fieldwork has no legal foundation.

Recorded Subdivision Plats

Most residential properties in Tampa are part of a recorded subdivision. The plat is the official map filed with Hillsborough County when the subdivision was created. It shows lot dimensions, street widths, easements and the location of the original survey monuments.

A licensed surveyor reviews the plat before fieldwork. It shows what dimensions and angles to expect. It shows where monuments should be and how the lot connects to the surrounding lots and streets.

When field conditions don’t match the plat, the surveyor investigates. A monument might be missing. A lot line might have shifted. An error in the original plat might have affected every lot in the subdivision.

Reviewing the plat early means the surveyor already knows what to watch for on site.

Prior Surveys of the Same Property

If a survey has been done on the property before, a licensed surveyor will review it. Prior surveys show where earlier surveyors located the boundary. They also show where monuments were placed and what measurements were recorded.

Comparing an older survey to current field conditions helps find problems. If a monument was in one spot in a 1995 survey and appears to have moved, that needs investigation. If the measurements don’t match the plat, the surveyor needs to understand why.

In Tampa’s older neighborhoods, lots have sometimes been surveyed many times over the past 50 or 60 years. Each prior survey adds useful context for the current one.

Title Commitments and Recorded Easements

A title commitment is prepared by a title company before a real estate transaction. It lists the recorded easements, restrictions and other items that affect the property. A licensed surveyor reviews this document to understand what rights exist on the land.

Easements must be located and shown on the survey. A utility easement along the rear of the lot affects where improvements can go. A drainage easement may restrict construction near a swale. An access easement may give a neighbor the right to cross part of the lot.

If a surveyor skips this step, a recorded restriction may be missed entirely. That causes problems during permitting or at closing when the easement turns up and the survey doesn’t show it.

In Hillsborough County, easements are recorded with the Clerk of Court. A thorough surveyor pulls the actual recorded documents to confirm the exact terms and dimensions of each easement.

Right-of-Way Documents and Road Plats

Public roads in Tampa have recorded right-of-way widths. Those widths define how much land next to the road is reserved for public use. The right-of-way boundary is not always where the pavement ends. In many cases, it extends well past the visible road surface.

A licensed surveyor reviews right-of-way plats and road dedication documents before fieldwork. This confirms where the public right-of-way ends and where private property begins. That line affects front setback rules and how close a structure can legally sit to the street.

In older Tampa neighborhoods, some road rights-of-way were recorded through documents that are hard to find. Reviewing these records early helps the surveyor account for them before the permit application is submitted.

County GIS Data and Tax Records

County GIS maps and property appraiser records give a licensed surveyor useful background information. They show the general shape of the parcel, the owner of record and the parcel identification number. Sometimes they include scanned images of older survey documents.

GIS data is not survey-accurate. It is built from recorded documents and aerial images. Parcel boundaries on county maps can be off by several feet. This data is useful for research, not for setting legal boundaries.

A licensed surveyor uses GIS and tax records to confirm basic facts and cross-reference the deed and plat. The actual boundary positions are determined in the field from recorded plats and legal descriptions, not from a county map on a screen.

Frequently Asked Questions

What Documents Does a Licensed Surveyor Review Before Fieldwork?

A licensed surveyor reviews the property deed, legal description, recorded subdivision plats, prior surveys, title commitments, easement documents, and right-of-way records. These documents provide the legal and historical information needed to perform accurate fieldwork and establish the correct boundary.

Why Does a Surveyor Need the Deed Before Measuring the Property?

The deed contains the legal description that defines where the property boundaries should be. Surveyors use this information to determine what to measure and which monuments to locate. The deed can also reveal issues such as conflicting descriptions or references to monuments that no longer exist.

How Do Recorded Easements Affect the Survey Drawing?

Recorded easements must be located and shown on the survey. They can limit where improvements may be built and identify areas with special rights or restrictions. Missing an easement during research can create problems during permitting or when the property is sold.

Are County GIS Maps Accurate Enough to Replace a Licensed Survey?

No. County GIS maps are based on recorded documents and aerial imagery, not on field measurements. Property lines shown on GIS maps can be several feet off. While they are useful for research, they are not a substitute for a professional land survey.

Why Do Prior Surveys Help When Working on the Same Property?

Prior surveys show previous measurements and monument locations. Comparing older survey information with current field conditions helps the surveyor determine whether monuments have moved, dimensions have changed, or discrepancies need further investigation.
