Real LIDAR terrain, slope, drainage, sun, viewshed, and driveway feasibility for any US property. $50 per report.
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.
A real civil-engineering site analysis costs $1,000–3,000 and takes weeks. Get the same critical answers in 30 seconds, for $50.
Send the report link to your spouse, your realtor, your builder. Everyone sees the same picture and asks the same questions.
Real data from USGS, FEMA, USDA, county assessors, and OpenStreetMap. The same sources professional engineers use — surfaced in a 3D visualization built for the question you actually have: can I put a house here, and what will it cost me to find out?
Any US address works. Type or paste — we'll show you matching properties as you type. Always free.
We check what data is published for your specific property and show you a full checklist before you pay. No surprises.
Pay once, get a permanent shareable link to the full interactive 3D analysis. Share it with anyone who needs to see it.
Most people only need one report — they're scoping a specific lot. Builders and realtors save with the unlimited plan.
Properties without full parcel records (rare — about 5% of US addresses) are automatically discounted to $25.
USGS 3DEP for LIDAR-derived terrain (1m resolution 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.
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. In areas where only 10m data is available, that's surfaced honestly in the badge.
No. LotScanner is a pre-purchase feasibility check — designed for "should I make an offer?" or "is this lot worth pursuing?". Before you actually build, you'll still want a surveyor to walk the property, a soils engineer to assess bearing capacity, and a civil engineer to design the site plan. Think of LotScanner as the first $50 you spend before you spend the first $5,000.
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.
7-day no-questions-asked refund. We'd rather hear what was missing than keep your money.
Absolutely — many of our users do exactly this when planning an addition, an accessory dwelling unit, a barn, a driveway redesign, or just to understand what they've got.
