The data you reported is coming from your county records, because of this I am unable to edit the information. This data is gathered by a third-party data collector and if correct with your county will be updated on Trulia when the updated data gets sent to us. My best recommendation would be to contact your county to ensure that the public records are up to date.
If the county records are correct and Trulia has not received the updated data yet, owners have the ability to edit their home facts on Trulia which appear in the 'Owner Information' section. Please know that edit home facts feature is currently removed from the property pages while we improve the feature. While we do not have a specific date for when they will be available, I can assure you this is only temporary. We thank you for your patience.
Once the feature is back, please follow these instructions on how to edit your home facts. This includes editing the number of bedrooms/bathrooms, square footage, home features, description and more.
Sign into your Trulia account. If you do not have an account, you must first register in order to update your home facts.
If you haven't already claimed your home, navigate to the property page, go to the "Edit Home Facts " button and verify ownership.
If you have claimed your home, click on the same "Edit Home Facts" button to update your home facts.
Make sure to select Publish Updates at the bottom of the page.
Thank you for using Trulia!
