Who can call themselves an architect in US marketing videos, websites and Instagram bios

A project film opens with "designed by the architects at Studio X", the Instagram bio says "architectural designer", the footer says "architecture + interiors". If nobody at Studio X holds a license in the state where that content is read, each line may violate a state practice act, and a board investigator can find them in a search. This guide explains who regulates the word "architect" in the United States, NCARB's role, how unlicensed designers and interior designers should describe themselves in captions and bios, and how to credit the architect of record in a film. Not legal advice; your state board's website is the authority.

Key takeaways

• In the US the title "architect" and the practice of architecture are regulated by state and territorial licensing boards, not by NCARB or the AIA; NCARB works with 55 jurisdictions and each sets its own rules.
• Most states also restrict derivatives such as "architectural" and "architecture" in business names and job titles when no licensee is involved; California's board says any form of the word used by an unlicensed person "may result in enforcement action".
• Unlicensed residential designers have plenty of accurate titles to use: designer, residential designer, building designer, design studio, project designer.
• Interior design titles vary by state: some protect "Registered Interior Designer", some "Certified Interior Designer", some "Licensed Interior Designer", and most states have no title law at all.
• In a project film, credit the licensed architect of record by name and firm, and describe your own role accurately in the same card.

Who regulates the word "architect" in the United States

There is no national architecture license. Each state, the District of Columbia and several territories issue licenses through a board, and each board's practice act defines both who may practice architecture and who may use the title. The National Council of Architectural Registration Boards, NCARB, is the membership organization of those boards. Its home page refers to "NCARB's 55 jurisdictions" and points candidates to "Contact Your Licensing Board" for requirements in their home state (NCARB). Its licensure page says plainly: "Each state has a different set of rules for practicing architecture" (NCARB, Become an Architect).

NCARB administers the three components most boards require, education, the Architectural Experience Program (AXP) and the Architect Registration Examination (ARE), and issues the NCARB Certificate that lets a licensed architect apply for licenses in other states more easily. It does not grant the title. A person who has finished a professional degree, completed AXP hours and passed every ARE division is still not an architect until a board issues the license.

The AIA is a professional membership association. Its "AIA" designation after a name tells you the person is a licensed architect member, but AIA membership is not itself a license, and the AIA does not enforce title laws. The California Architects Board notes that abbreviations and designations that imply licensure are also protected in that state (California Architects Board, Can I Call Myself an Architect?).

What the rules typically say

Wording differs by state, but the pattern is consistent. California's board fact sheet summarizes its law this way: "Any person who uses the title of 'architect' (or any term confusingly similar) or advertises to provide architectural services in California must be licensed as an architect by the Board." It warns candidates that using "any form of the term 'architect' (including 'architectural,' 'architecture,' or any abbreviations or confusingly similar variations) in their titles or to describe their services, prior to obtaining a California architect license, may result in enforcement action and/or the denial of a license", and it tells employers that "the use of any form of the term 'architect' in an unlicensed employee's job title or description is strictly prohibited" (California Architects Board fact sheet, November 2021).

Massachusetts is similar. The Boston Society for Architecture, reporting on the state board's position in 2023, wrote that "the term architect and any derivation of it, such as architectural designer, registered architect, etc., are protected by law", with "intern-architect" the one permitted exception for people in NCARB's experience program under a licensed architect's supervision (Boston Society for Architecture, May 4, 2023). NCARB's own blog, written during its title task force work, put it in one line: "you can only call yourself an 'architect' once you're licensed", and noted that many states prohibit any derivative of the word for unlicensed professionals (NCARB blog).

Consequences, in principle, run from a citation and administrative fine to a misdemeanor charge, and boards publish enforcement actions by name. Enforcement is complaint-driven, and complaints often come from licensed competitors who notice a caption or a bio.

Some states carve out exemptions for who may design what without a license, usually single-family houses and small buildings below a size threshold. That exemption is about practice; it does not give the designer the title. A residential designer in Texas or Arizona may lawfully design a house and still may not call the work "architecture" in a reel.

Interior design titles vary even more

Interior design regulation is a patchwork. CIDQ, the body behind the NCIDQ exam, keeps a jurisdiction list showing that about half the states plus the District of Columbia regulate interior design in some form, and that the protected title differs: "Certified Interior Designer" in states including California, Connecticut, Maryland, Minnesota, New York and Virginia; "Registered Interior Designer" in states including Alabama, Florida, Georgia, Illinois, Louisiana, Nevada, Tennessee and Texas; and "Licensed Interior Designer" in Oklahoma, New Mexico and the District of Columbia (CIDQ, Jurisdictions and Requirements). Most of these are title acts: anyone may practice interior design, but only a registrant may use the protected phrase. A few are practice acts that also restrict certain work.

The practical reading for marketing: "interior designer" on its own is unregulated in most states, "registered interior designer" and "certified interior designer" are protected phrases where the state has a law, and "interior architect" or "interior architecture" runs into the architecture title laws described above in many states. Kitchen and bath designers with NKBA credentials should use the exact credential name (for example, Certified Kitchen and Bath Designer) rather than any phrase that borrows "architect".

How unlicensed designers should describe themselves

Accurate titles are not a demotion. Clients hire residential designers, design-build firms and interior studios every day, and plain language about what you do converts better than a borrowed word that invites a complaint.

A few states permit specific phrases for people on the path to licensure. Check your board's site rather than copying another firm's bio from a different state; the bio you see in Chicago may not be lawful in Los Angeles.

Captions are read as advertising. If you post reels, run your caption templates through the table above once, then reuse them; the caption formulas for architects work equally well for a design studio once the title line is right.

Crediting the architect of record in a project film

Many project films are made by someone other than the licensed architect: an interior designer, a builder, a developer, a photographer, or a residential designer who collaborated with an architect on a stamped set. The right credit protects everyone and is good marketing, because the licensed firm will share a film that names it.

Put a credit card in the film or in the first line of the caption with these elements:

• Architect of record: firm name, and the licensed individual's name if the firm is small or the client wants it. Use the firm's legal name as the board lists it.
• Your role, stated precisely: "Interior design: Studio X", "Design collaboration and documentation: Studio X", "Builder: Y Construction", "Film: Z".
• Other consultants where the film shows their work: landscape architect (also a licensed title in most states), structural engineer, lighting designer.
• A rendering or AI note where the film includes concept imagery, following the wording in AI rendering disclosure for architects.

If you produce the film with Arch2Video, the optional studio logo on the end card should be the logo of the party publishing the film, and the credit to the architect of record goes in the caption or in a title card you add in your editor; the service does not add credits for you. Where the film shows unbuilt or concept work, label it as concept so the credit does not imply the architect has built something they have not.

For the written side of the same project, the case study page template has a credits block in the same order. Use identical wording in the film caption, the case study page and any client testimonial video so a board investigator or a curious client finds one consistent story.

A title audit for your studio

Do this once a year, or whenever someone joins or leaves, or when you start publishing in a new state.

1. List every public surface: website, Google Business Profile, Instagram, TikTok, LinkedIn (personal and company), YouTube channel, Houzz, email signatures, proposal templates, video title cards.
2. Search each for "archit" and read every hit in context. Business name, tagline, job titles, alt text and hashtags count; #architecture as a topic tag is usually fine, "#architect" as a self-description is not.
3. Check the states you market in, not only the state you sit in. A Kansas City studio that posts work in Kansas and Missouri answers to two boards.
4. Confirm who at the firm holds which license and in which states, and that any "Architects" in the firm name is supported by an active license in each state where you offer services.
5. For interior design, confirm whether your state protects a title and, if so, whether each person using it holds the registration.
6. Fix wording using the table above; keep a dated copy of the audit.

When a credential is real, show it: "AIA", "NCARB" and "NCIDQ" after a name tell clients something specific and verifiable. When it is not, the honest title still tells them what they will get, and that is the point of the rule.

Frequently asked questions

I have an architecture degree but no license. Can I say "architectural designer" in my bio?

In many states, no. Boards such as California's and Massachusetts's treat "architectural" as a derivative of the protected title and restrict it for unlicensed people. Some states allow a specific phrase for candidates in NCARB's experience program; check your board's site and use its exact wording.

Can my firm be called "Smith Architecture" if I am licensed in Texas but the firm also works in Colorado?

Firm names are regulated by each state where the firm offers services, and many states require a licensee responsible for the firm in that state and sometimes a firm registration. Before marketing in a second state, confirm the firm's status with that state's board; a reel that reaches Denver homeowners is an offer of services there.

Is "interior architect" a legal title in the US?

Rarely. It combines a protected word with a field that most states regulate separately, so it usually falls under the architecture title law. Use "interior designer", or the protected "Registered" or "Certified Interior Designer" if you hold that status in your state.

How should a builder credit the architect in a project reel?

Name the architect of record by firm (and individual if appropriate) in a title card or the first caption line, state your own role as builder or design-build contractor, and keep the wording consistent with your website. Ask the architect how they want the firm name written; the board's registry has the legal form.

What happens if a board decides my caption violates the title law?

Procedures vary by state, but outcomes range from a warning letter and required correction to a citation with a fine, and in some states a misdemeanor referral. A history of unlicensed advertising can also complicate a later license application. This is general information, not legal advice; ask your state board or an attorney.
