Steps to Firm Registration

Before your firm provides architectural or landscape architecture services in Ohio, please complete the following steps:

• Ensure that your firm meets each of the statutory ownership requirements to be eligible for firm registration. 
• If your firm meets the ownership requirements, contact the Ohio Secretary of State, Business Services Division, in order to obtain the business/corporate forms required to do business in the state of Ohio. The Ohio Secretary of State can be reached at (614) 466-3910 or toll-free at (877) 767-3453. They also can be reached on-line at: www.sos.state.oh.us/SOS/Businesses.aspx
• Once your firm is properly registered to do business in the state of Ohio by the Ohio Secretary of State, go to the eLicense Portal at https://elicense.ohio.gov to apply. You must create an account first, then you can apply for the license.
• During the online application process, you will be required to upload the following :
  • List of Firm Owners
  • A copy of the certificate/registration to do business in Ohio from the Ohio Secretary of State.
• You can pay the application fee with an electronic check or credit card. We accept VISA and MasterCard. After your firm's application for a new firm certificate of authorization has been approved, you will receive an email with a certificate permitting your firm to legally provide services in Ohio.
• If the firm is providing BOTH architecture and landscape architecture services, separate applications must be completed online. Each new license costs $125.

Important Information

• The cost of a new certificate of authorization is $125. The cost to renew a firm registration is $100.
• An eLicense System Transaction Fee pf of $3.50 will automatically be added to all transactions.
• If the firm registration has expired, a new application must be filed at a cost of $125.
• All firm certificates expire on June 30 of every year. Firms will be notified via email 60 days prior to the expiration date. Renewal is completed online at https://elicense.ohio.gov
• A "Firm Certificate of Authorization" and an architect's individual "Certificate of Qualification" (or license) to practice architecture are not the same thing.
• All changes in the firm's name, address, or ownership must be reported in writing to the board within 30 days.
• If a firm changes its name, it must apply for a new certificate of authorization.
• Firms using a trade name registered with the Ohio Secretary of State need to notify the Board in writing. However, a firm using a trade name is still required to file with the Secretary of State to do business in the state of Ohio and obtain a firm certificate of authorization. Both the legal name of the firm and any trade name must remain actively registered with the Ohio Secretary of State. Firms may not use an unregistered fictitious name.​
• Firms should include the complete firm name, or trade name, on all contracts, letterhead and title blocks. Firms should not shorten or abbreviate the legal name or any trade name in a manner that would be confusing or misleading.
• The use of firm or corporate seals are not permitted in Ohio. All sealed documents must bear the name and number of one active Ohio registered architect. Electronic seals are permitted in Ohio.
• Failure to comply with the firm registration requirements may result in penalties, including fines, suspension, or revocation of the designated architect's license.
• Firms without a current certificate of authorization are not permitted to provide architectural services in Ohio.
• Firms whose Ohio Secretary of State registration has been cancelled will have their application or renewal held in pending status until the firm has been reinstated.
• If it is determined by the Board that a firm's application does not meet the requirements, the firm may either withdraw the application and request a refund of the application fee, or request additional time in order to correct the deficiency.
