Quick comparison

Survey type Best for Typical outputs Ballpark cost*
Boundary survey Property lines, corners, fence placement, disputes Marked corners, boundary map, encroachment notes (scope varies) $450–$1,400
Topographic survey (Topo) Site design, grading, drainage, build planning Ground heights, contours, utilities, visible features $850–$3,500
ALTA/NSPS Commercial lender and title needs ALTA map plus title record items (Table A as needed) $2,200–$8,000
*Ballparks only: final price depends on lot size, site access, records work, schedule, and output needs. For a deeper estimate, see the Cost Guide.

How to choose fast

  • Fence, shed, or driveway near a line: start with a boundary survey or stakeout.
  • Design or grading work: start with a topographic survey. Some projects also need boundary data.
  • Commercial closing or refinance: lender/title teams often request ALTA/NSPS. Ask for written requirements.

Still unsure? Use the Survey Types picker, then request quotes.

Plain-language cheat sheet

  • Boundary survey: finds and marks legal lot lines.
  • Topographic survey: maps slope, height, and site features.
  • ALTA survey: supports many commercial lender and title deals.

Use the survey type that matches your next decision. That keeps cost and timeline on track.

Which deliverable do you actually need?

Most quote mistakes happen because the buyer asks for a survey type but really means a deliverable. Boundary, topo, and ALTA are not interchangeable, and the map, staking, CAD, and lender/title outputs are what drive the real scope.

  • If you need corners or a line decision: ask whether you need boundary map plus field marking, or only a stakeout.
  • If you need design files: ask for topo outputs, contour interval, and whether utilities or visible improvements are included.
  • If you need lender/title signoff: ask for the title commitment and Table A list before the surveyor quotes ALTA work.

One-minute summary

Start with your goal. Keep it short and clear.

  • Need lot line proof for a fence or dispute? Ask for a boundary survey.
  • Need ground shape and slope data for design? Ask for a topographic survey.
  • Need lender and title support for a deal? Ask if an ALTA survey is required.
  • Ask what files you will get: map, stake marks, and digital outputs.
  • Ask what is not in scope before field work starts.
  • Ask for target dates for field work and final map delivery.
  • Share permit, lender, and contractor needs in writing.

Scope checklist before you call a surveyor

Use this short list before you call a surveyor.

  • State your goal in one short sentence. Example: "I need a boundary survey for a fence permit."
  • Share the address, parcel number, and any known corner marker details.
  • List required outputs: staking, signed map, digital files, or lender package support.
  • Share your target date and hard deadlines from city, lender, or contractor.

Clear details lead to clear quotes. They also speed up scheduling.

What to send before you request quotes

Give the surveyor the decision context, not just the property address. The right note is usually one sentence about the goal, one line about the deliverable, and any outside-party requirements in writing.

  • Fence or dispute: send any plat, prior survey, or neighbor issue that affects the line decision.
  • Permit or grading: send the city or engineer checklist so topo and boundary needs are priced together if required.
  • Lender or title: send the title commitment, legal description, and Table A list before asking for ALTA pricing.

If your use case is already clear, jump to Survey for Fence, Survey for Permit, or Survey for Lender/Title.

Common mistakes that increase cost

Costs rise when scope changes after field work starts.

  • Starting with boundary only, then adding topo work later.
  • Ordering ALTA work before Table A items are confirmed.
  • Missing site access notes, like locked gates or active work zones.
  • Assuming map, CAD, and staking outputs are included without written scope.

Prevent this by locking scope and outputs before the first site visit.

FAQ

Which survey do I need for a fence or property line?

Most fence and property-line jobs start with a boundary survey. If you only need field stakes, ask about boundary stakeout or corner marking. See Survey for Fence.

When do I need a topographic (topo) survey?

Use topo when you need elevations and contours. It maps slope and site features for design, grading, drainage, and build planning. Many jobs need topo and boundary work together.

What makes an ALTA/NSPS survey different?

ALTA/NSPS surveys follow rules used in many commercial lender and title deals. They include items from the title commitment and Table A. If a lender or title company is involved, get needs in writing.

Can I combine boundary and topo work?

Yes. Many projects need both boundary and topo work. Share lender, permit, and design needs early so the surveyor can quote the right outputs. If you are not sure, start with Survey Types.
