Yes. The International Mechanical Code requires UL 2075 listing for any CO or NO2 monitor used to control ventilation in an enclosed parking structure. A monitor without UL 2075 approval will not pass inspection for parking garage applications.

Every vehicle entering an enclosed parking garage or underground parking structure produces toxic exhaust gases, including carbon monoxide (CO) and nitrogen dioxide (NO2).
In areas with limited ventilation, these gases can accumulate to levels that pose a health and safety concern to building occupants, particularly during periods of high traffic. Enclosed parking garages and parking structures rely on gas detection systems and ventilation control to prevent gases from exceeding recognized exposure limits set by OSHA, NIOSH, and other regulatory bodies. The International Mechanical Code (IMC) requires all CO and NO2 monitors used for ventilation control in enclosed parking structures to be listed to UL 2075, the industry standard for gas detection equipment used in life-safety applications.
Whether running continuously or on fixed operating schedules, a ventilation system that operates without the assistance of a gas monitor may be effective, but it is far from efficient. This traditional approach often results in excessive energy consumption and increased equipment wear, yielding unnecessary operating costs. Fixed-schedule ventilation also fails to adapt to changing conditions in real time, allowing gas concentrations to rise during unexpected periods of heavy vehicle traffic while simultaneously ventilating unnecessarily during low-occupancy periods.
Without real-time visibility into CO and NO2 concentrations, facility managers are left with two undesirable options:
Neither supports the goals of a safe, efficient, and cost-effective facility.
Partner with parking facilities to create safer, efficient ventilation on-demand systems through intelligent fixed gas monitors and ventilation controllers.
Smarter ventilation performance for reduced energy consumption and consistently clean air.
Demand-based ventilation operates only when needed, reducing unnecessary fan runtime and helping facilities significantly lower electricity costs up to 85% when compared to continuously running systems.
Ventilation fans, motors, and related equipment experience fewer operating hours, helping extend equipment life while reducing maintenance requirements and repair costs.
Continuous monitoring, automated controls, and integration with building systems help facilities maintain compliance with applicable air quality standards with greater confidence.

Yes. The International Mechanical Code requires UL 2075 listing for any CO or NO2 monitor used to control ventilation in an enclosed parking structure. A monitor without UL 2075 approval will not pass inspection for parking garage applications.
Yes, with distributed remote sensors. Our Optio multi-gas monitors can provide coverage across multiple potential release points, accumulation areas, elevations, and adjacent spaces, extending detection across complex facility layouts without requiring a separate monitor for every location or hazard.
As of 2021, carbon monoxide (CO) and nitrogen dioxide (NO2) detection are required for enclosed parking garages using automatic ventilation control to maintain compliance with the International Mechanical Code (IMC). The 2021 IMC Section 404.1 requires mechanical ventilation systems in enclosed parking garages to operate continuously or be automatically controlled using CO detectors in conjunction with NO2 detectors.
There is no universal sensor count rule based solely on parking garage size. Requirements vary by jurisdiction, which may specify minimum sensor quantities, spacing, or monitoring coverage. The number and placement of sensors should account for the applicable codes, garage layout, ventilation system, airflow, and known congestion zones.
Yes. Conspec gas detection systems can connect to ventilation, alarms, equipment controls, and building automation systems to support automatic response to changing gas concentrations. Our Primus V offers expanded control solutions for more complex operations.
Every enclosed parking operation has unique ventilation, traffic levels, and local building regulations. Our team is ready to help you design a monitoring solution that is the right fit for your operation.
