Cal. Civ. Code § SPS 328.04
Carbon monoxide detectors.
Operative Text
SPS 328.04 Carbon monoxide detectors. Carbon monoxide detectors shall be installed and maintained in accordance with s. 101.647 (2), (3) (a) and (b) and (6), Stats., in a dwelling, for which initial construction commenced before June 1, 1980.
Under Wis. Admin. Code § SPS 328.04, dwellings whose initial construction began before June 1, 1980 are required to have carbon monoxide detectors installed and kept in working order. The rule incorporates specific subsections of Wisconsin statute § 101.647 to define exactly how and where those detectors must be placed and maintained. This provision applies to the dwelling as a whole, meaning both the physical installation and ongoing upkeep must meet the referenced statutory standards.
Plain English — not legal advice.
Property owners and managers overseeing pre-1980 construction dwellings should be aware that Wis. Admin. Code § SPS 328.04 requires carbon monoxide detectors to be both installed and actively maintained in compliance with Wis. Stat. § 101.647(2), (3)(a) and (b), and (6). Compliant operators typically verify detector placement meets statutory location requirements, test units regularly, and replace devices that are expired or malfunctioning. Keeping records of installation dates and maintenance checks is a practice commonly associated with demonstrating ongoing compliance.

Code § SPS 328.04 entitles them to carbon monoxide detectors that are properly installed and maintained under the standards set by Wis. Stat. § 101.647. If a detector appears to be missing, non-functional, or improperly placed, tenants may consider documenting the condition and reaching out to local housing or building inspection authorities to report a potential violation.
