This guide provides a detailed overview of the licensing requirements for architecture industry firms and individuals in the state of Missouri.


Missouri Architecture Company Licenses

If you are operating as a business entity, obtaining the proper company licenses is the first step toward legal compliance.

Corporate Certificate of Authority (Architecture)

To practice architecture in Missouri as a corporation or limited liability company (LLC), your entity must obtain a Corporate Certificate of Authority from the Missouri Board for Architects, Professional Engineers, Professional Land Surveyors and Professional Landscape Architects.

Eligibility and Ownership Requirements

  • Eligible Entity Types: Business Corporations, Professional Corporations, and Limited Liability Companies.
  • Foreign Qualification: Yes, out-of-state entities must foreign qualify in Missouri before obtaining this certificate.
  • Business Corporations: Officers and directors do not need to be licensed, but the corporation must appoint a Missouri-licensed individual (a full-time employee) to be responsible for the firm's architecture practice in the state.
  • Domestic Professional Corporations: All shareholders, officers (other than the secretary), and directors must be licensed in a professional service performed by the corporation.
  • Foreign Professional Corporations: All shareholders, a majority of directors, and all officers except the secretary and treasurer must be licensed in the professional service.
  • Limited Liability Companies (LLCs): Members and managers do not need to be licensed. However, the LLC must appoint a full-time employee who is a Missouri-licensed architect to be responsible for the practice.
  • Partnerships (including LPs and LLPs): While partners do not necessarily need to be licensed, the partnership must appoint a full-time, Missouri-licensed employee to oversee the practice. Note: Partnerships are generally not required to obtain a certificate of authority from the Board, as their members are directly subject to Board regulation.

The Managing Agent

Firms must appoint a Managing Agent. This individual must be an owner, officer, member, manager, or full-time employee of the firm. Their responsibilities include:
* Renewing the certificate of authority and notifying the board of any firm changes.
* Overall supervision of professional and licensing activities.
* Ensuring the firm adheres to state statutes and board rules.
* Ensuring immediate personal supervision requirements are met across all offices.

Initial Registration Process

When applying for the first time:

  1. Entity Formation/Qualification: Domestic applicants must file entity formation documents with the Missouri Secretary of State. Foreign applicants must file foreign qualification documents.
  2. Certificate of Good Standing: Obtain a Missouri Certificate of Good Standing from the Secretary of State (it must not be more than 60 days old).
  3. Application: File the Application for Corporate Certificate of Authority with the Board.
  4. Requirements: You will need to provide a list of officers/directors/managers (with license numbers) and a list of licensed employees. Applications generally require notarization and a filing fee of $200. Turnaround is typically 1-2 weeks.

Registration Renewal

Licenses originally issued in even-numbered years expire on December 31 of each even-numbered year, while those issued in odd-numbered years expire on December 31 of odd years. Renewals can be completed online and generally cost $50 plus a small processing fee. You must provide an updated list of officers, managers, and licensees, as well as disclose any disciplinary actions.

Amendments and Reinstatement

  • Amendments: Changes to the managing agent require filing an Affidavit to Amend Managing Agent within 30 days. Other changes (contact info, officers) can often be done online.
  • Reinstatement: If your license lapses, a Re-Authorization application is required, accompanied by a $200 fee and a current Certificate of Good Standing.

Corporate Certificate of Authority (Landscape Architecture)

Firms offering landscape architecture services must also obtain a specific Certificate of Authority.

  • Ownership Requirements: Unlike standard architecture firms, there are no specific license requirements for ownership in Missouri for landscape architecture firms.
  • Foreign Qualification: Required for out-of-state entities.
  • Initial Registration: Requires an application, a $200 fee, a Certificate of Good Standing, and lists of officers, directors, and licensees. Notarization is required.
  • Renewal: Biennial renewal by December 31 (even/odd year schedule matching issuance). The fee is $50 plus online processing.
  • Amendments: Changes to the managing agent or other listed personnel must be reported within 30 days.

Interior Design Firm License

In Missouri, an Interior Design Firm license is not required at the state level. The state does not currently license or register interior design businesses.


Missouri Individual Architecture Licenses

In addition to firm-level licensing, the individuals practicing architecture within the firm must hold the appropriate personal licenses.

Missouri Architect License

  • Initial Registration: Requires passing the Architect Registration Examination (ARE). The application fee is $100.
  • Reciprocal Registration: Architects licensed in other states can apply via comity, typically using an NCARB Certificate. The fee is $200. Alternatives exist for those licensed for at least one year without an NCARB certificate.
  • Renewal: Renewals are biennial by December 31 (even/odd schedule) and cost $35 plus an online processing fee.

Missouri Interior Designer Registration
