Who Owns the Launch Render, and for How Long

TL;DR

• Paying the rendering invoice does not transfer copyright. Under 17 U.S.C. §204(a), a transfer of copyright ownership "is not valid unless an instrument of conveyance, or a note or memorandum of the transfer, is in writing and signed by the owner of the rights conveyed".
• Commissioning a render from an outside studio does not make it a work made for hire. §201(b) gives the employer authorship only in that narrow case, and an independent vendor's rendering is not it. What you hold without a signed assignment is a licence, and its scope is whatever the paperwork says.
• The inventory most launches never build has seven columns: asset, media, territory, term, exclusivity, design revision and credit. Write them before the first image enters production, because afterwards every gap is argued on your deadline.

What the invoice actually buys

A tower launch approves thirty images, pays, publishes, moves on. Two years later the remaining inventory goes back to market, somebody pulls the facade render off the server and puts it into paid media. Nobody asks a question, because the image has been paid for since 2024. That is where the arithmetic breaks.

The image was created by someone. Copyright in it vests in that someone at the moment of creation, and it reaches you by one of two routes: a signed assignment, or a licence. The invoice is neither. It records that production happened and that money changed hands, which is a different fact from who may publish the file in 2029, in which media, in which country.

United States law is unusually blunt about the writing requirement. §204(a) voids any transfer of copyright ownership that is not in a signed instrument. §201(b) carves out works made for hire, where "the employer or other person for whom the work was prepared is considered the author", but that route covers employees acting within the scope of employment and a short statutory list of commissioned categories. A visualisation studio invoicing you as a vendor sits outside it. Civil law jurisdictions reach a similar place by a different road: in Brazil, where we work, an assignment with no written term is capped at five years by statute.

The seven columns

A luxury launch carries more than a hundred files: facades, interiors, furnished plans, aerials, film, stills pulled from film. Managing that in server folders is the beginning of the problem. The sheet that holds up has seven columns per asset:

• Asset. A unique identifier, not "facade final v7". Version gets its own column.
• Media. Website, paid social, print, out-of-home, sales gallery, third-party portal, broker's own feed. Each is a separate permission, not a shade of the same one.
• Territory. Where the asset may run. If you raise capital in three countries, say so in the licence.
• Term. With a start date and an end date, not "for the duration of the launch". Launches end on an uncertain day.
• Exclusivity. May the studio show the image in its own portfolio and enter it into awards? The right answer is almost always yes, with a hold until your official reveal.
• Design revision. Which revision of the architectural set the image depicts.
• Credit. Who signs it, and on which assets the credit appears.

The revision column is the one nobody fills and the one that costs most. Pricing follows the same logic: we have written about what actually moves the cost of an architectural rendering, and scope of use belongs on that list beside camera count and detail level.

When the design changes after the image is approved

Approval freezes the image. It does not freeze the building. Balustrades change, the podium cladding changes, the plant floor gains height. The published render now shows a building that will not exist, and the exposure stops being a copyright question and becomes a consumer-protection question.

On the authorship side, moral rights sit under the commercial deal and do not move with it. Article 6bis of the Berne Convention gives the author the right to claim authorship and to object to modification of the work prejudicial to their reputation, and most Berne members implement some version of it. Brazilian law goes further for our discipline: the architect may publicly disown authorship of a project altered without consent, during construction or after it is finished. The studio that signs the render is not the studio that signs the project, and the render is still the artefact through which the public meets the project.

The operating rule is cadence. Any revision that changes massing, fenestration or visible finish triggers a revision of the image set, with a new date and a new row. The superseded asset stays in the library, marked out of use with the date it left circulation. That timestamp is what you will want when a buyer questions the facade three years on. Judgement on the new set still comes down to detail, which is why render quality in luxury real estate is read in the furniture.

The use that did not exist when you signed

Here is the clause that has not aged well. "Unrestricted, perpetual use for any purpose" was written in contracts drafted before anyone was feeding image libraries into a model. Several jurisdictions read an assignment narrowly against uses the parties could not have contemplated, and Brazilian statute says it outright: an assignment operates only for modes of use already in existence on the date of the contract. On that reading, a 2019 production agreement does not, by itself, authorise training a generative model on the development's image library in 2026.

The dispute has a scoreboard. The public count kept by the site Chat GPT Is Eating the World stood at 157 copyright lawsuits against AI companies, checked on 27 October 2026. None of them is about a property render. All of them turn on the same question: who authorised that specific use, and when.

The uncomfortable position, for anyone buying images: the broad adjective in your licence is weaker than it looks, because adjectives do not reach forward in time. A licence that survives this decade names media explicitly, names model training among them if that is the intent, and carries a date. If your studio refuses the training clause, that is a negotiation, not a surprise, and it is cheaper to have it now than in a deposition.

Credit is not a negotiating chip

Attribution costs one line of fine print. It is also the right that most systems refuse to let an author sell, which means a clause removing it is likely unenforceable in part of your footprint and reads as petty in all of it. Name the studio. On the day of a dispute over who made what and when, the credit line is your cheapest evidence.

FAQ

I bought the render and paid the invoice. Do I own it?

Not by payment alone. Copyright moves by a signed instrument under §204(a) in the United States, and by equivalent written-assignment rules in most other markets. Absent that instrument you hold a licence whose scope is read narrowly, and whose term may be fixed by statute rather than by your expectations.

How long should a launch licence run?

By the life of the product, not the life of the campaign. From teaser to handover, a luxury development runs four to six years, and remaining inventory keeps using the images after that. A two-year licence forces renegotiation at the worst possible moment, with the building selling and the studio knowing it.

Can the studio publish the images in its own portfolio?

Whatever the contract says, so write it down. The arrangement that avoids friction allows portfolio and awards use after your official reveal, bars commercial use for a third party, and carries the developer's credit on the asset.
