Virtual Home Staging: What Estate Agents Have Had to Label Since August

The three-bedroom flat has stood empty since the tenants moved out. White walls, a radiator under the window. In the photos, it looks bleak. So a member of staff uploads the images to a staging app. Ten minutes later, there's a grey corner sofa in the living room and geraniums are blooming on the balcony. The enquiries come in quickly. Then, at the first viewing, the prospective buyer falls noticeably silent.

The term "housefishing" has caught on for listings whose AI-enhanced images don't match the actual property. In September, Euronews asked whether the EU AI Act can do anything about it. For estate agents, the answer turns out to be quite practical. What used to be a question of style and decency is now, in many cases, a legal obligation. According to the European Commission, the transparency rules in Article 50 of the AI Act have applied since 2 August 2026.

The obligation applies to users too

The regulation distinguishes between the companies that make AI tools, known as providers, and the deployers that use those tools in a professional capacity. An estate agency using a staging app is a deployer. For deployers, paragraph 4 is the key provision. Anyone who uses an AI system to generate or manipulate image, audio or video content that constitutes a deepfake must disclose that the content has been artificially generated or manipulated.

According to the Commission's draft guidelines, intent to deceive is irrelevant. Well-meant staging is therefore caught just as much as a deliberately embellished image.

A second date often causes confusion: 2 December 2026. According to KPMG Austria, the so-called Digital Omnibus only postpones, until that date, the machine-readable marking required of providers whose AI systems were already on the market before August. For estate agents, nothing changes. Their disclosure obligation already applies.

The Commission published its final guidelines on Article 50 on 20 July 2026. They are not binding, but they show how Brussels interprets the rules. According to the Cloud Security Alliance, breaches can attract fines of up to €15 million or 3 per cent of worldwide annual turnover, whichever is higher.

Why property photos, of all things

The word deepfake brings to mind fake videos of politicians. The regulation takes a broader view. According to the specialist blog nicfab, it covers AI-generated or manipulated content that resembles existing persons, objects, places or events and could falsely appear to be authentic. A real flat is just such a place.

The Commission even cites, as an explicit example, a genuine photo of an empty flat that has been "furnished" using AI. According to Euronews, the EU classifies such an image as partially AI-altered and requiring an AI transparency icon. Anyone using virtual staging should therefore assume they need to label it.

Where the line is drawn

The following breakdown is practical guidance, not an official list. Conventional photo editing is generally unproblematic: a brightened kitchen, corrected white balance, straightened converging verticals, a clean crop. Afterwards, the flat looks the way a person would see it in good light.

It's a different matter as soon as something is added, removed or replaced. That includes inserted furniture, as well as a swapped sky, a green lawn in February, or a cellar from which AI has erased the previous owner's junk. Such images may be shown, but only with a disclosure.

Some things shouldn't be published at all. The water stain on the ceiling that has suddenly vanished. The bathroom that looks bigger thanks to distortion. The view of greenery without the electricity pylon that actually stands in front of it. Alongside the AI Act, unfair competition law continues to apply, as the AI imaging provider Immopix also points out, using the example of retouched-out cracks or patches of mould.

An AI disclosure doesn't make deception permissible. Anything that conceals a defect has no place in a listing, labelled or not.

In day-to-day practice, a simple test helps. If a prospective buyer sees something different at the viewing from what's in the photo, without the image having prepared them for it, something is wrong.

A disclosure no one can miss

According to the Commission's guidelines, the disclosure must be clearly perceptible and provided at the latest at the time of first interaction. Tucking it away in terms and conditions or menus is not sufficient, nor is purely machine-readable marking. A footnote on page twelve of the property brochure hardly meets that standard.

In practice, what works well is a clearly legible caption in one corner of the image that states specifically what was done. "Furniture added with AI" informs. So does "Sky digitally replaced". "Professionally enhanced", by contrast, tends to obscure.

The EU icon from the voluntary Code of Practice on transparency of AI-generated content is one way of implementing the disclosure, but it is not a requirement in its own right. In July, the Commission and the AI Board assessed the code as adequate for meeting the Article 50 obligations in practice. It describes how deployers can apply a disclosure including the icon. A clear text label on the image still makes sense, though, because not every prospective buyer will recognise the symbol.

The IVD training institute also recommends including the unaltered original photo in the marketing. A fixed order in the listing is practical. First comes the empty room, followed immediately by the furnished version with the note "Furnishing suggestion, created with AI". That way, there are no surprises at the viewing.

What gets lost in the XML feed

Hardly any agency still maintains its portal listings by hand. Properties go out via XML feed to several platforms, some of which pass them on to partner sites. Technical provenance data based on the C2PA standard is embedded in the image file itself, and according to Immopix, portals may strip it out on upload. A sentence in the description doesn't help much either if the search results only show the thumbnail or someone shares the photo in a messaging group.

That's why the disclosure should be visibly burned into the image. Then it travels with the file wherever it goes. Test the placement on a real property. A caption that looks fine in the full-size view is often illegible in a small thumbnail or gets cut off by automatic cropping. A bit of distance from the edge and a sufficiently large font size usually solve the problem.

One point still requires manual work. Some portals restrict captions or watermarks in photos, and articles in the trade press contradict each other on the details. Read the current image guidelines of every portal your feed delivers to yourself, and if in doubt, ask their support team before you switch over a hundred properties.

Keeping the image folder in order

At the latest when a prospective buyer asks what the bathroom really looks like, it becomes clear whether the agency keeps things organised. The original of every photo should be stored unaltered and separately from the edited versions. Each edited image should come with a short note on the tool used and the change made, such as "Staging app, sofa and rug added". That takes just a few minutes per property.

If you outsource staging to a service provider, you should stipulate in the contract that every AI alteration is reported and that the originals are supplied as well. The owner should also be informed. A sentence in the marketing agreement stating that edited images will be labelled saves a debate later about the disclosure on their photos. And the temp who uploads the listings on Fridays needs to know the rules just as well as the branch manager.

Existing listings and agencies in Switzerland

According to the law firm Paul, Weiss, listings published before 2 August 2026 do not have to be labelled retrospectively. However, anyone who lists a new property or uploads new images falls under the new rules. Longer-running listings are best brought into line at the next update.

For Swiss agencies, the matter isn't settled just because Switzerland isn't an EU member. According to Bird & Bird, under the final guidelines, simply publishing deepfakes on the globally accessible internet can trigger the obligations, even without specifically targeting the EU market. An agency in Basel with prospective buyers from Freiburg im Breisgau should therefore label its images just like its counterparts across the border.

Where this guide ends

This article provides a general overview of the topic and is not a substitute for legal advice. Interpretation will evolve as the first cases emerge. For a specific property or for contracts with service providers, a specialist lawyer or your own professional association is the right place to turn.

The first step for your own agency

Set aside an hour this week for your active listings whose images were uploaded after 2 August. Assign each edited photo to one of the groups above, then create a disclosure template to be used for every new property. Before each publication, a quick check of four points is then all it takes:

• The original is saved and the edit is documented.
• The image doesn't conceal any defect.
• Every item that was added, removed or replaced is specifically named in the image.
• The disclosure remains legible in the thumbnail and complies with the portal rules.

If you already store original and edited photos separately in the property record, for example in estate agency software such as ImotDesk, you'll have the evidence to hand quickly if it's ever needed.
