In the City and County of Denver , all installers of life safety systems, and all those who perform the service of inspecting those systems, must have current licenses issued by the Denver Fire Department. These safety systems include:

  • Fire protection systems (sprinkler systems)
  • Fire alarm systems
  • Portable fire extinguishers
  • Public Safety Bi-Directional Amplifier Systems (BDA)
  • Fire Pumps
  • Apprentices doing this work under a journeyman, who are registered in an approved apprentice training program or have a signed agreement in place with a contractor (see below), are required to be registered with the Denver Fire Department (but not required to hold a license). 
In the future, additional licensing programs will be added, such as smoke control and hood systems. An announcement will appear on this web page whenever a new licensing program is added.

  2019 Fire Safety License and Registration Renewals

  Notice to Central Stations (PDF)


To obtain a license, you will need to:

  • Apply for a license and pay a non-refundable application fee ($25)
  • Schedule an exam. (An application must be completed and submitted, along with an additional $75 fee for the test, to schedule an exam.)
  • Successfully pass the licensing test. The licensing test is made up of questions based on the relevant standards for that safety system; see the links below for details.
  • If you did not pass the test, you need to pay the $75 fee to take the test again.

  •  In code-revision years (generally every three years), all licensed installers/inspectors must reapply, pay the renewal fee (currently $75) and take the complete revised test. 2010 is a code revision year.
  • In non-code-revision years, installers may renew their license upon payment of a renewal fee. The renewal fee for installers/inspectors is subject to change annually. 2011 and 2012 are non-code-revision years.

All apprentice registrations must be renewed annually.

If you have any questions related to the Denver Department of Safety licensing program or would like to schedule a test, please contact the Fire Safety Systems Licensing Program Coordinator at 720-913-3465 or

Becoming Registered as an Apprentice

To be registered as an apprentice, you must:
  • Be registered in an approved apprentice training program focusing on the installation, repair and alteration of fire systems or electrical systems, or
  • Have a signed agreement in place with a contractor, indicating that within six (6) months of your hire you will be required to begin and complete an approved course of study and work experience.
  • Apply to be registered and pay the $20 registration fee.

License / Apprentice Card

Upon successfully passing the test or registering as an apprentice, you will be issued a license or an apprentice card, which is laminated and comes with a lanyard and a clip so that it can be kept with you while you are at work. You may slip the license or card into your pocket at times when it would be in the way, but in general it is to be kept visible at all times while on the job site.
