Survey Guide

Which Type of Land Survey Do You Need?

Updated September 2, 2026 · 4 min read · Survey Types

Quick answer

Choose the survey by the decision it must support. Property lines call for boundary work; design needs site features and elevations; flood paperwork may require an Elevation Certificate; a title transaction may specify ALTA/NSPS; construction needs layout or as-built verification.

Start with the decision, not a survey name

A homeowner rarely needs “all survey information.” They need enough reliable information to place a fence, design drainage, close a transaction, obtain flood documentation, divide land, or build from plans. Tell the surveyor that purpose first. Because licensure is state based, use the NCEES licensure overview to reach the controlling board and confirm who may provide the required service.

This prevents two expensive errors: buying work that does not answer the real question, or buying a limited product and discovering later that a permit office, lender, title company, or designer needs something else.

For property lines, ask about a boundary survey

A boundary survey develops a professional opinion of the parcel boundary from record and field evidence. It can be scoped to include corner recovery or setting, selected line staking, a signed drawing, visible occupation, or other agreed features.

Use it when the location of ownership affects a fence, structure, purchase, dispute, clearing project, or land-use decision. Do not substitute an assessor map or phone GPS for the surveyor's work.

For design, ask for topographic and feature information

A topographic survey records elevations and specified site features for engineering, architecture, drainage, grading, landscape, or permit work. The USGS explanation of topographic maps describes contour lines as connecting points of equal elevation, allowing a map to show the shape and slope of the ground.

Your designer should define limits, required features, contour interval or point density, vertical datum, control, utility information, and file format. A public topographic map may provide regional context, but it is not a project-specific design survey.

For title due diligence, confirm whether ALTA/NSPS is required

An ALTA/NSPS Land Title Survey is a coordinated national product for title-related transactions. The 2026 standard requires a defined package of records review, fieldwork, map, certification, and any requested Table A items.

Do not select Table A items from memory or an old checklist. Ask the lender, title company, attorney, and surveyor to agree on the current scope and certification parties.

For flood paperwork, identify the exact form or determination

An Elevation Certificate records building and elevation information used in National Flood Insurance Program work. FEMA explains that the form can support floodplain management, rating, and map-change processes, but it does not by itself change the mapped flood zone. See FEMA's current description before ordering.

First ask the insurer, lender, floodplain administrator, or permit office which document is needed. An existing certificate may already be available, and some requests are for a map determination rather than new field measurements.

For construction, distinguish layout from verification

Construction staking transfers positions and elevations from approved plans to the site. An as-built or record survey measures selected completed conditions for comparison with plans, permits, or contract requirements. Neither service automatically determines the full property boundary unless boundary work is included.

Give the surveyor approved plans, current digital files, project control, site contacts, sequencing, tolerances, requested stakes or marks, and inspection deadlines. Revised plans can require revised layout.

For land division, start with the local approval path

Subdivision, parcel-map, lot-line-adjustment, and platting terms vary by state and locality. These assignments often connect surveying with planning review, access, utilities, legal descriptions, monumentation, and recording. Contact the planning or land-records office before assuming a simple boundary survey will create a new legal parcel.

Use a one-minute scope test before requesting estimates

  • Decision: what will happen after the survey?
  • Authority: who is asking for it, such as a permit office, lender, title company, designer, insurer, or attorney?
  • Physical work: what must be measured or marked?
  • Deliverable: stakes, signed drawing, CAD file, certificate, plat, or another defined product?
  • Deadline: which later event depends on delivery?

Then verify the responsible professional through the state licensing board. NCEES explains the state-based surveying licensure system and links to licensing resources.

Frequently Asked Questions

Can one survey serve more than one purpose?

Sometimes. A surveyor may combine compatible fieldwork and deliverables, but the combined scope should be written before work begins. Do not assume a boundary drawing includes design topography, flood certification, or construction staking.

What survey do I need for a fence?

Usually start by asking for a boundary survey with the relevant corners or line marked. Confirm local permit and site-plan requirements before finalizing the scope.

What survey do I need for a commercial purchase?

Ask the lender, title company, and attorney whether they require a 2026 ALTA/NSPS Land Title Survey and which Table A items are needed.
