What it can't tell you
- It doesn't look at the whole parcel, its boundaries, title, easements, zoning or permits.
- It isn't a survey, appraisal, elevation certificate, soil or perc test, or Phase I environmental site assessment.
- It can't see local distribution power lines, driveways, legal access, wells or mineral rights.
- Maps lag behind the ground, and distances are straight-line, not driving distance.
Common questions
Can I check a specific property in St. Louis County?
Yes. Enter the address or drop a pin anywhere in St. Louis County. The free preview shows which checks returned data at that exact point, and the full report costs $29 (initial test price).
What flood zone is land in St. Louis County?
It depends on the exact spot. At our sample point near the middle of the county, FEMA's flood map returned zone X. A parcel a few hundred feet away can be in a different zone, so check your own pin.
Is this a survey or title search?
No. It is a preliminary screen of mapped public data at one point, not a survey, title search, appraisal, perc test or Phase I environmental site assessment.
