Original source-coded research | version 1.0.0 | checked July 15, 2026
There is no single national disclosure field for an AI-altered listing photo
Direct answer: in this purposive 20-source benchmark, 19 official MLS or association sources publish specific virtual-staging or alteration language, but only 7 explicitly name AI. Seven require an original or same-view unaltered copy, one recommends it, and two explicitly say an original is not required. The safest reusable workflow is to preserve the original and route disclosure to the exact surfaces named by the current market rule.
This is a cross-market source directory and workflow benchmark, not legal advice, a national census, or a statement that public silence means permission.
What changes when the rules are coded row by row
- AI language is still the minority: seven sources explicitly name AI. The other rows govern through virtual staging, enhanced media, digital alteration, photo manipulation, or broader accuracy language.
- Disclosure placement is a system design choice: the sample includes on-image or MLS-applied labels, photo descriptions, public remarks, broker remarks, structured fields, and public-original links. Several sources require more than one.
- Original-image handling is not uniform: seven sources require an original or same-view unaltered image, one uses nonbinding recommendation language, two expressly say it is not required, and the rest do not state a public requirement in the cited source.
- Rule strength matters: NorthstarMLS is coded as best-practice guidance because its source uses `should` language. The benchmark does not silently upgrade that advice into a binding rule.
- Silence is not a green light: the OneKey row records the broader accurate-media policy visible publicly and marks staging-specific fields as not publicly verified.
The useful synthesis: build disclosure as a capability matrix
A compliant workflow cannot be inferred from the phrase `virtually staged`. The record should carry the unaltered source, the transformation, the selected market profile, and every required disclosure surface through export.
Store an immutable original, the edited derivative, the editor or model, date, and listing/media identifier.
Version the official source and map its current rule strength, placement fields, labels, original-copy posture, and edit limits.
Generate the image label, caption, public remarks, broker remarks, structured MLS field, and original URL only where the profile calls for them.
Use a preflight review for structural, fixture, landscape, view, defect, dimension, and surrounding-property changes before syndication.
Vendor test: ask whether the product can retain the original, produce a same-view pair, preserve a source manifest, and export different disclosure combinations by MLS. A single `AI disclosed` checkbox does not cover the source patterns in this benchmark.
Twenty official market policies with row-level sources
Each responsive card exposes the same 14 fields without a sideways-scrolling comparison table. `Not stated` and `not publicly verified` are evidence limits, not permission or prohibition.

Methodology, definitions, limitations, and corrections
- Sample design: a purposive cross-market benchmark of 20 distinct official public MLS or REALTOR-association sources, not a representative national survey.
- Primary-source rule: row coding excludes vendor blogs, staging-company summaries, forums, search snippets, and law-firm summaries.
- Conservative coding: AI is explicit only when the source names it. Required, recommended, explicitly not required, not stated, and not publicly verified are kept separate.
- Dates: a policy’s visible revision, effective, or publication date remains separate from TPTK’s July 15, 2026 checked date.
- Coverage limits: policies can change and public sources may omit subscriber-only instructions. State, local, brokerage, ethics, advertising, copyright, privacy, fair-housing, and platform rules can also apply.
- No legal advice: this dataset compares public policy text and workflow implications. It does not determine whether a specific image, edit, listing, or disclosure is lawful.
Corrections: email hello@theprotoolkit.com with the stable row ID and current official source. Material corrections will receive a dated revision or new semantic version.

Frequently asked questions
Does every MLS require an AI or virtual-staging label on the image?
No. The published workflows in this 20-source purposive sample range across on-image or system labels, photo descriptions, public or broker remarks, structured MLS fields, and original-image links. Some sources combine several surfaces, and one source in the sample publishes only a broader accurate-media rule.
Should agents keep the original image even when the public MLS rule does not require it?
Keeping an immutable original is the most portable operational baseline because seven reviewed sources require an original or same-view unaltered copy and one recommends it. That retention step is an evidence practice, not a claim that every MLS requires an upload.
Is this benchmark legal advice or a list of every U.S. MLS rule?
No. It is a dated purposive benchmark of 20 official public MLS or REALTOR-association sources. It is not legal advice, a national census, or a substitute for current subscriber rules, brokerage review, and state or local requirements.
What does not stated or not publicly verified mean?
It means the cited public source did not provide enough language to code that field. It does not mean the organization permits the practice or lacks an internal, subscriber-only, or newly revised policy.
