Pre-Drywall Scanning vs. Real-Estate Marketing Tours
A real-estate marketing tour and a builder's documentation scan look similar on screen but solve different problems. Here is how to tell which one a project actually needs.

A marketing tour and a documentation scan are built on similar hardware and look almost identical the first time you open them. They are not the same product, and using one where you needed the other is an expensive mistake. The short version: a marketing tour is built to show a space; a pre-drywall scan is built to record it.
The one-sentence answer
If the goal is to sell or present a finished space, a 20–30 position marketing tour is the right tool. If the goal is to find a service run inside a wall years from now, you need a 50–500+ position documentation scan taken before drywall closes.
Where they differ
Scan density
A marketing tour uses 20–30 positions per floor — enough for a visitor to walk through and get a feel for the space. A documentation scan uses 50–500+ positions on a typical custom home, so every wall cavity is captured from at least two angles and nothing important hides behind a stud or a stack.
Timing
A marketing tour is shot once, when the home is finished and staged. A pre-drywall scan has exactly one window: after rough-in inspections clear and before insulation and drywall go up. Miss that window and the information is sealed inside the walls.
What you do with it
You share a marketing tour with buyers. You open a documentation scan when a warranty question lands, when a trade needs to pre-walk a space, or when an owner renovates in ten years and needs to know what is behind the ceiling.
When you need both
High-end custom builds often want both: a dense pre-drywall record for documentation and warranty, and a clean finished-state tour for marketing and owner handoff. Captured by the same team in two visits, they share a workflow and a hosting account.
How to decide
Ask one question: will someone need this record after the walls are closed? If yes, you need a documentation-grade pre-drywall scan, not a marketing tour. See why pre-drywall scanning matters for the warranty case, or step into a real 10,000 sq ft Birchview Estate pre-drywall record.
