# AI-powered square-footage breakdown by floor

`GET /api/properties/sqft-per-floor/`

1 credit

## What it returns

Per-floor square-footage distribution for a US residential property, derived from a multi-stage AI analysis (photo/room detection, architectural-style inference, and multi-method validation). Returns the total square footage and a `square_feet_by_floor` map keyed by floor.

## When to use it

- Break out living area by floor for renovation, valuation, or listing copy.
- Sanity-check a single total-sqft figure against a per-floor split.

**Note:** this is a heavy AI workflow — use a **45-second client timeout**.
