Requesting a land survey quote is easier when you know what information to provide. You do not need to have every technical detail figured out before contacting a surveyor, but a few key details can help the survey team understand your property, your project, and the type of survey that may be needed.
Whether you are a property owner, developer, architect, engineer, contractor, broker, attorney, or title professional, preparing the right information can help reduce delays and make the quote process more efficient.
Why the Right Information Matters
Land surveying is not one-size-fits-all. A boundary survey, topographic survey, ALTA/NSPS survey, construction staking request, elevation certificate, or specialty survey may each require a different scope of work.
The survey team needs to understand what decision the survey is meant to support. Are you trying to confirm property lines? Prepare for architectural design? Support a commercial transaction? Stake construction improvements? Resolve an encroachment concern? The purpose of the survey helps determine the appropriate approach.
Start With the Property Address
The property address is the most basic starting point. It helps the survey team identify the site, review available records, understand the general location, and evaluate service area logistics.
If the property does not have a standard street address, provide as much location information as possible. This may include nearby intersections, parcel maps, legal descriptions, coordinates, or other identifying details.
Include the Assessor’s Parcel Number if Available
The Assessor’s Parcel Number, often called the APN, is especially helpful. The APN helps identify the specific parcel and can reduce confusion when multiple parcels, vacant land, large properties, or unusual addresses are involved.
If you do not know the APN, it may be available through county assessor records, property tax documents, title materials, purchase documents, or online property information resources.
Explain Why You Need the Survey
One of the most helpful things you can provide is a plain-language explanation of why you need the survey.
For example:
- “I am planning to build a fence and need to know where the property line is.”
- “Our architect needs a topographic survey before beginning design.”
- “The lender is requesting an ALTA/NSPS survey for a commercial property purchase.”
- “We need construction staking for a new building pad.”
- “There may be an encroachment from a neighboring wall.”
- “We need an elevation certificate for flood insurance or permitting.”
You do not have to use technical survey language. The goal is to help the surveyor understand the problem you are trying to solve.
Identify the Type of Survey, if You Know It
If you already know the type of survey being requested, include that information. Common examples include:
- Boundary survey
- Topographic survey
- ALTA/NSPS Land Title Survey
- Construction staking
- Parcel map or lot line adjustment support
- Elevation certificate
- As-built survey
- 3D topographic scanning or point cloud survey
- Specialty survey services
If you are not sure which type of survey is needed, that is okay. The survey team can help identify the appropriate scope based on your project goals.
Share Your Timeline
Survey timelines can vary based on property complexity, records research, field conditions, title materials, agency requirements, weather, site access, and current workload. Providing your desired timeline helps the survey team evaluate scheduling and communicate expectations early.
Be specific if there is a deadline. For example, let the surveyor know if the survey is needed before a closing date, permit submittal, design meeting, construction start, lender deadline, or court-related date.
Provide Deeds, Title Reports, or Legal Descriptions
Property records can be very important, especially for boundary surveys and ALTA/NSPS Land Title Surveys. Helpful documents may include:
- Grant deed or vesting deed
- Legal description
- Preliminary title report or title commitment
- Recorded easement documents
- Parcel maps or subdivision maps
- Prior surveys, if available
For commercial transactions, title materials are especially important. Providing them early can help the surveyor understand recorded easements, exceptions, access rights, and other title-related matters that may affect the survey.
Include Plans, Drawings, or Project Documents
If the survey is connected to design, engineering, permitting, or construction, include any available plans or project documents. These may help the survey team understand the area of interest and the level of detail needed.
Helpful documents may include:
- Architectural plans
- Civil engineering plans
- Site plans
- Grading plans
- Improvement plans
- Landscape plans
- Utility plans
- Previous survey drawings
Even preliminary plans can be helpful if they show the project area and intended improvements.
Describe Site Access Conditions
Site access can affect scheduling and fieldwork. Let the survey team know if the property is gated, occupied, vacant, under construction, secured, or difficult to access.
Helpful access details include:
- Gate codes or access instructions
- Contact person for site entry
- Business hours or restricted access times
- Locked yards, rooftops, utility areas, or fenced areas
- Pets, tenants, security personnel, or construction crews on site
- Parking limitations or safety requirements
Clear access information helps reduce missed appointments and field delays.
Clarify the Area to Be Surveyed
Sometimes the entire property needs to be surveyed. Other times, only a portion of the site is relevant. If you know the specific area of concern, explain it clearly.
For example:
- “Only the rear property line is in question.”
- “The architect needs the full parcel and adjacent street frontage.”
- “The contractor needs staking for the building corners and utility trench.”
- “The lender needs the entire commercial parcel included.”
- “We need topo information around the proposed addition area.”
Defining the area of interest can help the survey team recommend the proper scope.
Let the Survey Team Know Who Else Is Involved
Many survey projects involve more than one person or organization. Sharing the right contacts can help streamline communication.
Depending on the project, this may include:
- Property owner
- Buyer or seller
- Real estate broker
- Title company or escrow officer
- Attorney
- Lender
- Architect
- Engineer
- Contractor
- Developer or project manager
This is especially important when survey requirements are coming from a third party, such as a lender, title company, architect, engineer, or municipality.
You Do Not Need to Have Everything Figured Out
It is common for clients to be unsure what type of survey they need. In many cases, the first step is simply explaining the property, the project goal, and the deadline.
A professional survey team can help clarify whether your project may require a boundary survey, topographic survey, ALTA/NSPS survey, construction staking, specialty survey, or a combination of services.
