Certificates of Fitness

Effective 5/17/2021, COF holders can apply, renew and make payments online to save time.

The Fire Department of New York (FDNY) issues Certificates of Fitness (COF) for various types of dangerous occupations. We provide study materials, other guidance and tests to individual applicants to ensure they know how to safely use, store and handle dangerous materials in the workplace. Under the New York City Fire Code, a COF is needed to:

  • Manufacture, store, handle, use, maintain, inspect, test or transport certain materials.
  • Conduct certain operations.
  • Operate certain facilities.

See list of Certificates of Fitness below for Study Materials and exam specific information.

To obtain a Certificate of Fitness

COF exams can be taken at FDNY Headquarters. Most COF exams are walk-in exams. Exam fees can be paid by credit/debit card, check or money order only. Cash is no longer accepted. Applicants who have completed application and payment online will have a shorter wait time.

The following COFs require an appointment before taking the exam at FDNY Headquarters: F89, F80, Q01, S56, S98.

You must have a COF application ID before scheduling the appointment.

To make a group appointment

Groups of ten (10) applicants or more MUST contact FDNY.BusinessSupport@FDNY.nyc.gov to schedule an appointment.

Certificate of Fitness Application

COF applications can be completed online or in-person at the FDNY Headquarters. FDNY highly recommends COF candidates use the online application BEFORE coming to FDNY Headquarters.

Candidates who complete the online application and payment will be processed faster and have a shorter wait time to take the exam.

(2) Comprehensive COF Renewal: Renewal COF with a NYC ID.

All COFs can be renewed online by logging in with a NYC ID, including Fee Exempt COFs.

You can also upload supporting documents (such as proof of employment) and change your mailing address online.
