Under the standard AIA owner-architect agreement, the architect owns its drawings, specifications and models, including the copyright, and the client gets a license to use them only for its project. That ownership is why some architecture firms can license their archives to AI developers, where contractors usually cannot. The limits come from the contract actually signed: owner-drafted agreements often transfer copyright, consultants own their own files, and confidential, security-sensitive or export-controlled projects stay out.
- Under AIA B101-2017, the architect and its consultants own their instruments of service, including copyright.
- The client's license covers its own project only, so the client cannot license your drawings to an AI developer either.
- Owner-drafted contracts often transfer copyright to the client: check each project before including it.
- Consultants own their own drawings and models; leave them out unless they agree.
Who owns architectural drawings: the architect or the client?
Under the standard AIA contract, the architect does. In B101-2017, "the Architect and the Architect’s consultants are deemed the authors and owners of their respective Instruments of Service, and they retain all common law and statutory rights, including copyright." The client gets a narrower right: "The Owner receives a license to use the Instruments of Service solely and exclusively for constructing, using, maintaining, altering and adding to the Project" (AIA Contract Documents).
"Instruments of service" is the AIA's term for the architect's work product on a project: drawings, specifications, models and the other documents the firm prepares. Federal law protects the design itself too. An architectural work "is the design of a building as embodied in any tangible medium of expression, including a building, architectural plans, or drawings." (17 U.S.C. 101).
This page is general information, not legal advice: it states what each contract or rule says, with its source, and your counsel decides how it applies to your firm.
Do architects own their drawings? It depends on the contract you signed
Only if the contract kept the copyright with the firm. The AIA warns that "many owner-drafted agreements attempt to transfer ownership of the architect’s copyright to the owner." (AIA). Public owners, developers and large institutional clients often use their own forms, so a firm's archive is usually a mix of projects it owns and projects it does not.
| Contract on the project | Who usually owns the drawings and models | Can the firm license them for AI training? |
|---|---|---|
| AIA B101-2017 or a similar form, unchanged | The architect (and each consultant for its own work) | Often yes, subject to confidentiality and the other checks below |
| Owner-drafted agreement that assigns copyright to the client | The client | No, unless the client agrees in writing |
| Assignment limited to project-specific material | Split: the client owns project-unique parts, the firm keeps its standard details | Only the firm's own standard material, separated out |
| In-house design team of a developer or owner | The employer: work by an employee is a work made for hire | The employer decides, not the designers |
The AIA also notes that a firm's documents usually include "some of your own standard drawings, details, specifications, and other materials" developed before the project (AIA). Even where a client took the project copyright, a firm may keep its standard library if the assignment excluded it. Federal law makes "a work prepared by an employee within the scope of his or her employment" a work made for hire, owned by the employer (17 U.S.C. 101).
Who owns the BIM model and the CAD files: architect or client?
The same rules apply: a Revit model or a set of CAD files is an instrument of service, so under B101 the firm that authored it owns it. The AIA's BIM exhibit does not change that. "AIA Document E203–2013 does not create a license to use digital data"; it sets protocols on top of the license in the main agreement (AIA Contract Documents).
Shared models are where ownership gets mixed. A federated model often contains the structural engineer's and MEP engineer's models, and B101 treats each consultant as the owner of its own work; the architect only obtains "similar nonexclusive licenses from the Architect’s consultants" for the project (AIA B101-2017). License your own model files, not the federated model, unless every author agrees.
What AI developers want from architecture and engineering firms
They want the working record of design, not finished renderings. Archinect reported that AI companies are building models and agents for tasks "such as reviewing drawings and writing RFI responses", and that one offer asked for CAD files "including revisions and markups" (Archinect). Fast Company reported that "the data that could be used to train an architecture AI model is not widely available (or stealable) online." (Fast Company).
| Record | Why a developer wants it | Ownership note |
|---|---|---|
| Native Revit, ArchiCAD or AutoCAD files with revision history | Shows how a design changed and why | Firm-owned under B101; consultant models are theirs |
| Issued drawing sets by phase (SD, DD, CD) | Pairs early and final versions of the same building | Firm-owned under B101 |
| RFIs with the architect's responses | Teaches answering contractor questions against the drawings | Questions are the contractor's text; answers are yours |
| Redlines, markups and QA/QC comments | Shows what reviewers catch | Firm-owned if made by your staff |
| Code-review comments and plan-check correspondence | Links drawings to code requirements and corrections | Reviewer comments come from the jurisdiction; check before including |
| Specifications and the firm's standard detail library | Reusable technical text and details | Usually firm-owned even after some copyright transfers |
Expert screen recordings of design software are a separate market: Markov says such data "is especially scarce for expert workflows in domains like CAD, architecture, engineering, finance, and other professional software." (Markov). Engineering data in general (parts, assemblies, BOMs, simulations) is covered in licensing CAD files and engineering data.
Can an architecture firm sell its drawings or Revit models?
Usually it licenses them rather than selling them. A license gives the AI developer defined rights to use a prepared copy for training, while the firm keeps ownership and can keep using its details on future projects. Selling the copyright outright would stop the firm from reusing its own work, which few firms want.
Ownership is necessary but not enough. As one architect put it to Archinect: "Just because a firm possesses these files doesn't necessarily mean it has the right to sell them for AI training." and "Removing client names doesn't necessarily resolve those issues." (Archinect).
| Material | Without client consent? | Why |
|---|---|---|
| Your own drawings and models on B101-type projects with no confidentiality designation | Often yes | The firm owns the copyright and the client's license is project-only |
| Your standard details, specifications and templates | Usually yes | Developed before and outside any one project |
| Projects where the client took the copyright | No | The client owns it |
| Information the client designated confidential or business proprietary | No | B101 section 10.8 requires the receiving party to "keep such information strictly confidential" |
| Consultants' drawings and models | No, needs the consultant | Each consultant owns its own instruments of service |
| Security-sensitive, critical infrastructure or defense projects | No, and often not at all | Federal rules restrict the design information itself |
The confidentiality wording is from B101-2017 section 10.8 (AIA B101-2017).
What must stay out: confidential, security-sensitive and export-controlled work
Four kinds of project stay out of a first license, whatever the ownership clause says.
- Client-confidential projects. Anything a client designated confidential, and projects under separate nondisclosure agreements (common for retail, technology and healthcare clients).
- Critical infrastructure. FERC defines critical energy infrastructure information as "specific engineering, vulnerability, or detailed design information about proposed or existing critical infrastructure" (18 CFR 388.113). Utility, substation and similar design work stays out, and so do prisons, courthouses, data centers and other buildings where the floor plan is a security risk.
- Defense and export-controlled work. ITAR technical data "includes information in the form of blueprints, drawings, photographs, plans, instructions, or documentation" for defense articles (22 CFR 120.33). Under the EAR, releasing controlled technology to a foreign person in the US "is a deemed export" (15 CFR 734.13).
- Personal information. Residential clients' names and addresses, staff names in title blocks and PDM logs, and photos of occupants. Replace names with codes; see the de-identification guide.
How to prepare an architecture firm archive for AI licensing
Sort on paper before anyone exports a file. Most of the work is a contract review by project.
- List projects by year, building type and region, with the contract form used (AIA or owner-drafted) and whether copyright was transferred.
- Mark projects with confidentiality designations, NDAs, security sensitivity or export control. They are excluded first.
- Separate your own models and drawings from consultants' files in each project folder.
- Keep the history: issued sets by phase, revision clouds, RFI logs with responses, and markups, linked to the drawings they refer to.
- Strip client names, addresses and staff names from title blocks and file properties.
What AI companies pay for architecture data: the honest evidence
No sale of an architecture firm's drawings to an AI developer, and no price for one, has been published. What exists is offers and claims, graded below.
| Evidence | What it says | Source grade |
|---|---|---|
| Nyne.ai post reported by Archinect | "We’ll pay you six figures" for three years of CAD files (Archinect) | Named press reporting a buyer's social post; an offer, not a deal |
| Archinect on intermediaries | "several platforms have emerged offering to serve as brokers" for architecture and construction firms (Archinect) | Named press; no prices given |
| Fast Company on the big labs | "None of the big AI labs are currently attempting to tackle this challenge." (Fast Company, August 2026) | Named press |
Read six figures as a ceiling someone advertised, not a market price. Value depends on how many projects you own outright, how much history the files keep, and how many building types they cover. Before talking to any buyer, see how to vet an AI data buyer and the Nyne review.
Architecture firm valuation and new revenue streams
A data license is a possible new revenue stream for a firm that owns a long archive, but do not count it in an architecture firm valuation until a contract is signed: no published valuation method assigns a value to drawing archives. See new revenue streams for B2B companies and what is my business worth.
Contractors on the same projects face a different position, because the design documents are not theirs; see licensing construction project records.

Common questions
Who owns architectural drawings, the architect or the client?
Under the standard AIA owner-architect agreement, B101-2017, the architect and its consultants own their drawings, specifications and models, including copyright. The client receives a license to use them only for constructing, using, maintaining, altering and adding to its project. An owner-drafted contract can change that by transferring copyright to the client, so check the agreement for each project.
Can my architecture firm license old project drawings to an AI company without asking the client?
Sometimes. On projects under an unchanged AIA B101 agreement the firm owns the copyright, and the client's license is limited to its project. You still need the client's consent where the client took the copyright, designated information as confidential, or signed a separate NDA. Leave out consultants' files and any security-sensitive or export-controlled work.
Does the client own the Revit model if we sent them a copy at closeout?
No, not under the AIA forms. Delivering a model gives the client a license to use it for the project, not ownership. The AIA's BIM exhibit, E203-2013, does not create a license by itself; rights follow the main agreement. An owner-drafted contract may say otherwise, so read the ownership and deliverables clauses.
Can we include our structural and MEP consultants' models in a data license?
Not without their agreement. B101-2017 treats each consultant as the author and owner of its own instruments of service, and the architect only obtains a nonexclusive license from them for the project. License your own model files and get each consultant's written consent before including theirs, or remove their content from federated models.
An AI company offered our architecture firm six figures for CAD files: is that a normal price?
There is no normal price yet. Archinect reported a Nyne.ai post offering six figures for three years of CAD files, but no closed sale or price for an architecture archive has been published. Treat an offer as a starting point, check which projects you own outright, and compare written offers before agreeing to anything.
What architecture data do AI developers want most?
Native CAD and BIM files with their revision history, drawing sets issued at each phase, RFIs with the architect's responses, redlines and QA comments, and code-review correspondence. Archinect reports AI companies building tools for reviewing drawings and writing RFI responses, which need the questions, the drawings and the answers linked together.
Will AI replace architects?
Not on current evidence. The Bureau of Labor Statistics projects architect employment to grow 4 percent from 2025 to 2035, about as fast as average. AI tools are being built for parts of the work, such as drawing review and RFI answers, and Fast Company reported in August 2026 that the big AI labs were not yet tackling architecture data at all.
