Why people use LotScanner

One report that answers "is this lot worth it?"

Don't buy the wrong lot

A flat-looking lot can hide a 15% slope. A wooded lot can hide a wetland. Find out before you make an offer — not after closing.

Skip the engineering quote

A real civil-engineering site analysis costs $1,000–3,000 and takes weeks. Get the same critical answers in 30 seconds.

What's in your report

The same six lenses every site analysis walks through.

Real data from USGS, FEMA, USDA, county assessors, and OpenStreetMap — surfaced in a 3D visualization built for the question you actually have: can I put a house here?

Terrain & Topography

The actual shape of the ground, derived from real LIDAR — not guessed from satellite imagery.

3D model from LIDAR (1m resolution where available)
Adaptive contour lines (2 ft or 5 ft)
Elevation min, max, and total drop
Native data tier + acquisition year

Buildable Area

Algorithmic detection of where on the lot you can actually put a house — accounts for slope, setbacks, and shape.

Best building pads ranked by size + slope
Buildable square footage per region
Distance to road from each pad
Overall buildability score (0–100)

Water & Drainage

How water moves across the lot, and what's officially flagged as flood- or wetland-prone.

Surface water flow patterns (drainage arrows)
Drainage sinks (where water collects)
FEMA flood zone designation
National Wetlands Inventory overlay

Sun, Views & Privacy

Sun exposure across the entire lot, and what you'll see (or hide) from any point on the property.

Solar gain heatmap (% of day in direct sun)
Sunrise/sunset bearings across the year
Viewshed from any point — see what's visible
Best viewpoints ranked by visible area

Access & Driveways

Where the driveway can plausibly go, what slope it'll have, and what it'll cost in cut/fill.

Auto-computed candidate driveway paths
Slope profile + max grade per route
Draw-your-own driveway with live analysis
Total rise/run, length, average grade

Property Records

Authoritative county-assessor data — precise lot lines, ownership, zoning, and sale history.

Precise lot boundaries (via Regrid)
Acreage, perimeter, road frontage
Current owner of record
Zoning, land use, last sale + date

FAQ

Questions we hear a lot.

Still stuck? Email hello@lotscanner.com — we read every message.

Where does the data come from?

USGS 3DEP for LIDAR-derived terrain (1m where available, 3m or 10m elsewhere), FEMA NFHL for flood zones, USFWS NWI for wetlands, county-assessor records via Regrid for parcel boundaries and ownership, and OpenStreetMap for roads. The same public-domain sources professional civil engineers use.

How accurate is the terrain?

Where USGS publishes 1m LIDAR (≈95% of CONUS as of 2026), vertical accuracy is typically under 30cm — sufficient to identify meaningful slope, drainage, and building pads. We label every report with the exact data source and acquisition year so you never have to guess.

Is this a substitute for a real site survey?

No. LotScanner is a pre-purchase feasibility check — designed for "should I make an offer?" Before you actually build, you'll still want a surveyor, a soils engineer, and a civil engineer. Think of LotScanner as the first $50 you spend before the first $5,000.

Do you have my lot?

Most likely yes. We cover essentially every US address that has a postal record. The address search above will tell you exactly what's available for your specific property — including precise lot lines when published, or approximate ones with a discount if not.

What if the report isn't useful?

7-day no-questions-asked refund. We'd rather hear what was missing than keep your money.

Can I use this for a property I already own?

Absolutely — many of our users do exactly this when planning an addition, an ADU, a barn, a driveway redesign, or just to understand what they've got.
