Zillow receives the numbers for total square footage that appears on the floor plan from the information that syndicates to their system on the MLS. If the listing is off-market, the square footage listed will be from a previous listing. Once the listing is live, the floor plan will pull the total square footage from MLS.   Floor plans are created by Zillow based on data submitted through the 3D Home app. All dimensions are approximate and subject to independent verification. We can remove individual room dimensions from the floor plan if you need!   Since the total square footage is not generated by Zillow, we are unable to edit or remove this information from our floor plans
