PropDiagram is an online tool that turns a street address into a numbered diagram of the buildings on the property (a property diagram, also called a plot plan, plot map, site diagram or sketch diagram), with each building's length, width and footprint square footage. The diagram is made for you from aerial-imagery-derived building outlines in about a minute, and you can correct it with your own measurements before downloading a PDF.
You can pay per successful report or subscribe monthly with reports included each month; current rates are on the Pricing page. There is no contract and no minimum. A report that fails is not charged, and editing a report or downloading it again is free.
The building footprints are drawn and measured automatically. Occasionally walls and dimensions may need to be tweaked for better accuracy using the tools provided, and you can add a building that is new or missing from the aerial imagery.
Yes. When an underwriter asks for a plot plan, site diagram or sketch diagram, a PropDiagram report gives them every building numbered and measured, the distances between buildings and to the hazards you mark, lot lines when available, and a dated PDF to attach to the submission.
Property insurance agents, underwriters, loss control and risk management staff, and claims adjusters who need a clear record of what is on a property and how big it is.
Building outlines are detected from aerial imagery and are typically within a few feet. The square footage is the ground footprint (the 1st floor); upper floors are added by you. It is an estimate, not an appraisal, survey or replacement cost valuation.
Reports can be run for addresses in all of the lower 48 states and Washington, DC. Lot lines are added where county parcel maps are available.
Detailed site diagrams and property data to support property insurance underwriters, loss control and risk management.
