© 2026 PropDiagram.com · Measurements are approximate footprint estimates, not an appraisal or survey.

Building diagrams and measurements are derived from a variety of databases and/or imagery. Occasionally aerial imagery available may cause discrepancies in the outline, or significant (approx >5%) deviations from actual building footprint. Multiple tools are provided as part of this service for the user to make corrections, revisions, additions, or deletions to allow for an end product to be as reasonably accurate as possible, just short of manual field verified measurements. Alternatively the end user may use this tool for a rough draft, then use the tools provided to develop an accurate, scale diagram based on their own field verified measurements.
