Summary

California law, applied to every Tracy home, requires owners to install a State Fire Marshal-listed carbon monoxide device in any dwelling with a fossil-fuel heater, fireplace, or attached garage. Health and Safety Code Section 17926 set a July 1, 2011 deadline for existing single-family homes, and violations draw up to a $200 fine per offense.

(a) An owner of a dwelling unit intended for human occupancy shall install a carbon monoxide device, approved and listed by the State Fire Marshal pursuant to Section 13263, in each existing dwelling unit having a fossil fuel burning heater or appliance, fireplace, or an attached garage, within the earliest applicable time period as follows: (1) For all existing single-family dwelling units intended for human occupancy on or before July 1, 2011. (2) For all existing hotel and motel dwelling units intended for human occupancy on or before January 1, 2017. (3) For all other existing dwelling units intended for human occupancy on or before January 1, 2013. ... (c) (1) Notwithstanding Section 17995, and except as provided in paragraph (2), a violation of this section is an infraction punishable by a maximum fine of two hundred dollars ($200) for each offense. (2) Notwithstanding paragraph (1), a property owner shall receive a 30-day notice to correct.

Full Breakdown

030). Subsection (a) requires an owner of a dwelling unit intended for human occupancy to install a carbon monoxide device, approved and listed by the State Fire Marshal, in every existing unit that has a fossil fuel burning heater or appliance, a fireplace, or an attached garage. The compliance deadlines are staggered: existing single-family dwellings had to comply by July 1, 2011; existing hotel and motel units by January 1, 2017; and all other existing dwelling units, such as apartments and condominiums, by January 1, 2013.

Subsection (b) requires the number and placement of the devices to match either the building standards for new construction of that occupancy type or the manufacturer's installation instructions, whichever is technically feasible. New construction in Tracy installs the required alarms as part of the adopted California Residential and Building Codes at the time of permitting; existing homeowners carry the ongoing installation duty directly under state law rather than a separate city ordinance. The statute caps liability for noncompliance: no real estate transfer can be invalidated for a missing device, and the exclusive civil remedy is actual damages up to $100.

Violations & Fines

A violation of Health and Safety Code Section 17926 is an infraction punishable by a fine of up to $200 per offense, but subsection (c)(2) requires the property owner first receive a thirty-day written notice to correct before that fine can be assessed. Failure to install a required device does not affect title to the property and carries no separate criminal exposure beyond the infraction fine.

Frequently Asked Questions

Does Tracy require carbon monoxide detectors in every home?
State law does, and it applies here. Health and Safety Code Section 17926 requires the owner of any dwelling with a fossil-fuel heater, fireplace, or attached garage to install a State Fire Marshal-listed carbon monoxide device. Existing single-family homes had to comply by July 1, 2011, and new construction gets the devices installed under Tracy's adopted 2025 California Residential Code.
What happens if a Tracy landlord skips the carbon monoxide alarm?
The owner first gets a thirty-day written notice to correct under Section 17926(c)(2). If the alarm still isn't installed after that window, the violation becomes an infraction punishable by a fine of up to $200 per offense, and a tenant harmed by the omission can recover actual damages up to $100.
Where must the CO alarm go in my house?
Section 17926(b) ties placement to either the current building standards for new construction of that type of dwelling or the manufacturer's installation instructions, whichever is technically feasible to follow in an existing structure. Tracy's adopted 2025 California Residential Code sets those placement standards for any new work.
