What Is a Spot Survey?
A spot survey (or spot elevation survey) verifies that construction matches the approved plans at critical stages. It's typically required by the building department before foundation pour, framing, and final inspection.

When spot surveys are required
Most jurisdictions require a spot survey after foundation forms are set but before concrete pour (verifying setbacks and elevations), and sometimes after framing (verifying height). The surveyor certifies that the structure location matches the approved site plan.
What it verifies
Building setbacks from property lines, finished floor elevation (critical for flood zones and drainage), building height, and lot coverage. If the spot survey reveals the building is in the wrong location, it's caught before concrete is poured — when fixes are still feasible.
Cost and scheduling
Spot surveys run $300-$800 per visit. Schedule the surveyor 48-72 hours before your planned pour or inspection. The building department won't approve the next inspection phase without the spot survey certification on file.
The bottom line
Spot surveys verify building location before concrete pour. Required by most jurisdictions, they catch setback errors when fixes are still feasible.
