CO Detector Rules in Tennessee: What Rentals and Hotels Must Do
Last verified: February 17, 2026
Tennessee carbon monoxide detector laws are occupancy-specific at the statewide level. The cited statutes make it unlawful to operate covered hotels and covered one-family or two-family rental units with carbon monoxide-emitting features, such as fossil-fuel equipment or fireplaces, without approved alarms installed within 10 feet of each sleeping room.
Tennessee sources also define accepted listing standards and power options, including hardwired, monitored battery, and plug-in pathways when statutory conditions are met. This creates clear statewide duties for rentals and lodging in covered scenarios, while broader all-home applicability remains dependent on occupancy and code context.
Tennessee operators should maintain unit-level installation, testing, and correction records with statute references before occupancy, renewal, or inspection events.

Where to Install CO Alarms
- Approved alarms must be installed within 10 feet of each room used for sleeping in covered Tennessee hotel and rental scenarios.

Device Requirements
- Devices are listed to nationally recognized laboratory standards including ANSI UL 2034 or ANSI UL 2075 in cited Tennessee sources.
- Combination smoke and carbon monoxide devices are allowed when applicable listing standards for both functions are satisfied.
- Installation follows NFPA standards or manufacturer directions unless conflicting law language controls.
- Allowed power pathways in cited Tennessee materials include hardwired, monitored battery, and qualifying plug-in approaches.
Landlord and Tenant Responsibilities
Landlord: Owners and operators of covered one-family and two-family rental units must provide required approved alarms in statutory trigger scenarios.
Tenant: Occupants must not tamper with or remove required smoke or carbon monoxide alarm devices.
- Short-term rental treatment should be confirmed against the exact statutory definitions applicable to the specific property type.
Enforcement
Enforced by: Local code and fire officials plus statutory enforcement mechanisms for unlawful operation in covered Tennessee contexts.
Enforcement typically occurs:
- During inspections and enforcement actions for covered rental and hotel occupancies.
- During complaint, incident, or licensing-related review where required alarms are missing or non-operational.
Penalties for Non-Compliance
Cited Tennessee statutes characterize covered noncompliance as unlawful; exact penalty classification should be confirmed in current codified sections used by the enforcing authority.
Tennessee statutory amendments to sections 68-120-112 and 68-102-151 in cited bill materials.
Additional Notes
- Tennessee compliance should be run by occupancy category because statewide duties are not framed as one universal home rule.
- Operators should verify current codified wording with local enforcing authorities before final policy publication.
