To meet the Missouri architect license requirements, you need a professional degree from a program accredited by the National Architectural Accrediting Board, 3,740 documented hours through NCARB’s Architectural Experience Program, and passing scores on all six divisions of the Architect Registration Examination. Once those are complete, you apply to the Missouri Board for Architects, Professional Engineers, Professional Land Surveyors and Professional Landscape Architects and pay a $100 filing fee.1Missouri Secretary of State. Missouri Code of State Regulations 20 CSR 2030-6.015 – Application, Renewal, Relicensure, and Miscellaneous Fees The Board operates under the state’s Division of Professional Registration and handles every step from education verification through ongoing compliance.2Missouri Department of Professional Registration.

Do You Actually Need a License?
Missouri reserves the title “architect” and the practice of architecture to license holders, but the statute carves out a few situations where you can do the work without one.3Missouri Revisor of Statutes. Missouri Revised Statutes Section 327-091 – Practice of Architecture Defined You can provide architectural services for a single-family home or a duplex without a license, provided you do not call yourself an architect on any drawings or documents.4Missouri Revisor of Statutes. Missouri Revised Statutes Section 327.101 – Unauthorized Practice Prohibited, Licensure Required, Exceptions
A similar exemption covers small commercial buildings: no more than nine occupants, less than 2,000 square feet, and not part of a larger structure. The title restriction still applies.4Missouri Revisor of Statutes. Missouri Revised Statutes Section 327.101 – Unauthorized Practice Prohibited, Licensure Required, Exceptions Other exemptions apply to employees working under a licensed architect’s direct supervision, in-house staff designing facilities only for their own employer, and licensed professional engineers whose architectural work is incidental to an engineering project. If none of these fit your work, you need the license.
Education
The standard route is a professional degree from a NAAB-accredited program. In practice that means a five-year Bachelor of Architecture or a Master of Architecture built on a pre-architecture undergraduate degree. Candidates without an accredited degree still have options, covered further down.
The Architectural Experience Program
After your degree, you log hands-on work through NCARB’s Architectural Experience Program. The requirement is 3,740 hours across six experience areas spanning site design through project management. At least 1,860 of those hours must come from working in an architecture firm under a licensed architect; the remaining 1,860 can be earned in other settings, which gives candidates more flexibility than earlier versions of the program allowed.5National Council of Architectural Registration Boards. Experience Requirements
The Architect Registration Examination
You must pass all six divisions of the ARE 5.0.6National Council of Architectural Registration Boards. ARE Overview – Architect Registration Examination Each division lines up with an AXP experience area, so your work hours and your study tend to feed each other. Divisions can be taken in any order and do not need to be completed in one sitting.
If You Don’t Have a NAAB-Accredited Degree
A non-accredited degree does not automatically shut you out. One common route is an Education Evaluation Services for Architects (EESA) review, which compares your transcript against NCARB’s education standard and flags any coursework you need to add. As of January 2026, NCARB also retired the three-year waiting period that non-NAAB-degree holders previously faced before applying for NCARB certification, so licensed architects without an accredited degree can now apply for certification immediately upon licensure.7National Council of Architectural Registration Boards.

How to Apply
Applications go through the Missouri Division of Professional Registration. The forms ask for personal identification, professional references, your employment history in architecture, and an educational chronology, along with disclosure of any prior out-of-state licenses and disciplinary history.8Missouri Division of Professional Registration. Architects – Application Forms
Most applicants attach an NCARB Council Record, which bundles verified transcripts, AXP hours, and ARE scores into a single file and streamlines the Board’s review. Update your Council Record before you file so dates and details match your state forms exactly.
The filing fee for initial licensure by examination is $100, and all fees paid to the Board are nonrefundable.1Missouri Secretary of State. Missouri Code of State Regulations 20 CSR 2030-6.015 – Application, Renewal, Relicensure, and Miscellaneous Fees Applications are processed in the order received, and the Board does not commit to a specific timeline.8Missouri Division of Professional Registration. Architects – Application Forms
Already Licensed in Another State
Missouri offers two reciprocity paths. The traditional one is licensure by comity with a current NCARB Certificate. Because the Certificate already verifies that you met nationally recognized benchmarks, the Board’s review of whether your original state’s standards were substantially equivalent to Missouri’s tends to go quickly.9National Council of Architectural Registration Boards. Reciprocity
The second path comes from House Bill 2046, enacted in 2020. Missouri waives its education and experience requirements for any applicant who has held a license for at least one year in a state that sets its own minimum education and experience standards. Your out-of-state license must be current and in good standing, you cannot be under investigation or active discipline, and you cannot have a disqualifying criminal record.10Missouri Division of Professional Registration. Architects – Application Forms – Section 324.009 This route is useful for architects without an NCARB Certificate who otherwise have a clean record.
Your Seal Once You’re Licensed
Every Missouri-licensed architect must obtain a personal seal at their own expense. It is a 1¾-inch circle reading “State of Missouri” across the top and “Architect” across the bottom, with your name and license number (prefixed by the letter “A”) in the center. Embossing seals, rubber stamps, and computer-generated images are all acceptable so long as they match the required design.11Missouri Secretary of State. Missouri Code of State Regulations 20 CSR 2030-3.060 – Licensee’s Seal
You seal, sign, and date every sheet of your final technical submissions, including drawings, specifications, reports, and construction certifications. Documents clearly marked as preliminary or not for construction are the exception. Revisions to a sealed document need their own seal, signature, date, and an explanation of what changed.
If Your Firm Is a Corporation or LLC
Individual licensure covers you personally. If your practice is organized as a corporation or LLC, the entity itself must obtain a Certificate of Authority from the Board before it can offer architectural services in Missouri, and the certificate renews on the same biennial cycle as individual licenses.12Missouri Revisor of Statutes. Missouri Revised Statutes Section 327.401 – Right to Practice Not Transferable, Corporation Certificate of Authority Required The firm must designate a Missouri-licensed architect, employed full-time, who is in responsible charge of all architectural work the firm performs in the state.13Missouri Secretary of State. Missouri Code of State Regulations 4 CSR 30-10.010 – Application for Certificate of Authority Professional corporations face stricter rules on who may be a shareholder, officer, or director.
Operating without a valid Certificate of Authority exposes the firm to civil penalties of up to $5,000 per offense, with each day of continued violation counting separately and a cap of $25,000.14Missouri Revisor of Statutes. Missouri Revised Statutes Section 327-077 – Civil Penalties May Be Imposed
Renewing Your License
Missouri architect licenses run on a two-year cycle. Licenses first issued in an even year expire December 31 of each even-numbered year; licenses first issued in an odd year expire December 31 of each odd-numbered year.15Missouri Division of Professional Registration. Renewal Information The individual renewal fee is $35.1Missouri Secretary of State. Missouri Code of State Regulations 20 CSR 2030-6.015 – Application, Renewal, Relicensure, and Miscellaneous Fees
Renewal requires 24 continuing education units during the two-year cycle. At least 16 must cover health, safety, and welfare topics through structured educational activities; the remaining 8 can address any subject relevant to architectural practice. You can carry up to 12 excess hours into the next cycle.16Legal Information Institute. Missouri Code 20 CSR 2030-11.025 – Continuing Education for Architects Keep records of activity type, sponsoring organization, location, duration, and instructor in case of audit. Falling short results in nonrenewal, potential discipline, or both.
If a license lapses, Missouri distinguishes between “inactive” and “expired” status and has separate reactivation applications for each. The relicensure fee is $200.17Legal Information Institute. Missouri Code 20 CSR 2030-6.015 – Application, Renewal, Relicensure, and Miscellaneous Fees Contact the Board directly about the continuing education and documentation required in your specific situation.
Penalties for Practicing Without a License
Unlicensed architectural practice in Missouri is a Class A misdemeanor, which can carry up to a year in jail and a fine of up to $2,000.18Missouri Revisor of Statutes. Missouri Revised Statutes Section 327.076 – Licensure Required, Penalty for Violation The Board can also pursue civil penalties of up to $5,000 per offense through the Administrative Hearing Commission, with a $25,000 cap for continued violations.14Missouri Revisor of Statutes. Missouri Revised Statutes Section 327-077 – Civil Penalties May Be Imposed The conduct covered is broad: using the title “architect” without a license, using someone else’s license or seal, misusing a seal, submitting false information to the Board, and helping someone else practice without authorization.
