California Code § 1596.954: Carbon Monoxide Detectors

This regulation requires every licensed child day care center to have one or more carbon monoxide (CO) detectors installed that meet California's safety standards. These detectors must be present and functional at all times, and licensing inspectors will check for them during facility inspections. Carbon monoxide is a deadly, odorless gas that can come from heating systems, gas appliances, or attached garages, making these detectors a critical safety requirement.

As of November 23, 2025, 16 facilities have been cited for this violation in the past 90 days, affecting 9 counties across California. That's approximately 1 in 2,500 facilities statewide. Los Angeles County had the most citations with 6 facilities, followed by San Bernardino and San Diego with 2 each. This represents about 0.21% of the 7,551 facilities inspected during this period.

Inspectors cite facilities when they find no carbon monoxide detector installed, when detectors are not functioning (dead batteries, expired units), or when detectors don't meet California's required standards. Common issues include: detectors that have passed their expiration date (most CO detectors expire after 5-7 years), detectors placed in improper locations (too close to fuel-burning appliances or in areas with poor air circulation), or facilities that removed detectors during renovations and forgot to reinstall them.

First, install CO detectors that are certified to meet California standards (look for UL 2034 certification). Place them according to manufacturer instructions - typically on every level of your facility and near sleeping areas if you have nap rooms. Test detectors monthly by pressing the test button, replace batteries at least annually (or install units with 10-year sealed batteries), and replace the entire detector when it reaches its expiration date (check the back of the unit for the manufacture date). Keep documentation of installation dates and testing schedules. If your facility has gas appliances or an attached garage, this requirement is especially critical.

Purchase and install compliant CO detectors immediately - don't wait for the correction deadline. Take photos showing the installed detectors, their location, and the certification label showing they meet standards. Document the installation date and test the units to ensure they're working. Submit your correction documentation to licensing with proof of purchase and installation photos within the required timeframe. If your facility has unique layout challenges that make placement difficult, consult with your licensing analyst before installing to ensure proper placement.
