For OPERATIONAL Permits please see Fire Safety Operational Permits

Notice to building owners and contractors: IFC 912.4.1

*Notice to building owners and contractors:

Plan Review & Testing Services

The City and County of Denver requires that plans and specifications be reviewed by plan review experts prior to approval of building or installation permits. The purpose is to provide safety through ensuring compliance with local ordinances, including the fire code.
The plan review process involves personnel from a number of different agencies, so in most cases you will need to start elsewhere--not directly with the Fire Department--and the appropriate portions of the review will be directed to us. 
Here are some general guidelines:

If you are planning . . .

  Please see:

a multi-family or commercial construction project

 Denver Development Services website

a single-family residence or small project

to install life-safety systems (fire alarm, fire sprinklers, smoke detection, carbon monoxide detection, smoke control, emergency communications systems, etc.) that are not part of a larger, overall construction project

If you would like to discuss specific issues or design questions about your project with our Plan Review personnel before submitting formal plans

  Pre-Application Plan Review Service

Denver Fire Department Fire Protection Engineers and uniformed firefighters in the plan review unit review:

  • Site plans
  • Water plans
  • Building and life safety system plans and specifications


They are also equipped to prepare recommendations or consult with individuals involved in building construction, remodeling or renovations. They contribute a high level of technical ability to the plan review process, interpretations, consultations, and the preparation of recommendations for a broad range of complex fire protection problems, and their expertise is recognized by architects, engineers, builders, and other professionals involved in the building process.

After a life-safety system has been installed, inspection personnel from the Fire Prevention unit must conduct an inspection to determine that is has been installed properly and is functional. 
Life-safety systems that require testing include:
  • fire alarms
  • fire sprinklers
  • smoke detection and alarms
  • carbon monoxide detection and alarms
  • smoke control
  • public-address systems
  • firefighters emergency communications systems
  • emergency generators
  • fire pumps
  • radio enhancement systems
  • kitchen hood extinguishing systems
  • special extinguishing systems
  • emergency elevator recall

A successful life-safety systems acceptance test usually results in a temporary or permanent certificate of occupancy.
There is no charge for initial acceptance testing unless you need to schedule the testing for a time outside normal business hours. If initial acceptance testing occurs outside normal business hours, a fee is charged. A fee is also charged for any re-tests (i.e., in cases when the initial test or subsequent tests determined that the system did not function in accordance with applicable standards). 

PLEASE NOTE: Inspections and fire systems tests that occur outside of normal business hours must be cancelled within one business day (24 hours) from the start time of the inspection or test. 

Any cancellations outside of this timeframe will be assessed the applicable fees. If the inspection or test occurs, and fails, the normal re-inspection fee schedule ($300 first re-inspect, $500 all subsequent re-inspections) will be assessed in addition to the applicable fees for outside of normal hour testing. All cancelled tests will be rescheduled by calling the testing line. 

Fees for construction-related Services
Fire Prevention has fees in place for two construction-related services:

  • Fire Safety Systems Retest - for systems (smoke alarms, fire alarms, sprinkler systems, etc.) that have failed a previous functionality/compliance test. In many cases, we find that, due to pressures to move the project forward, the contractor has not pre-tested the system; in other words, contractors are using the first City test as their pre-test.  We encourage contractors to perform their own pre-test to avoid having to pay a retest fee. The fee is $300 for the first retest and $500 for each subsequent retest. (There is no change for initial acceptance testing unless you need to schedule the testing for a time outside normal business hours.)
  • Contractor-paid Overtime / Standby Personnel - for fire safety system inspections or fire safety systems acceptance testing that the contractor has requested be conducted outside normal business hours. The hourly fee is $80. In accordance with Denver Fire Code Section 106.2.9, this fee also applies to standby personnel.

Both fees can be avoided by a contractor’s diligent preparation (i.e., pre-testing systems) and scheduling of all inspections and testing during normal business hours.

Refer to the installation permit for details about timing of and arranging for a post-installation inspection, or contact the Life-Safety Systems Acceptance Testing Group at 720-913-3480 or
