What Oklahoma Requires for CO Detectors Under Amended IRC
Last verified: February 17, 2026
Oklahoma carbon monoxide detector laws for residential settings are anchored in Uniform Building Code Commission adoption of the 2015 IRC as a statewide minimum code framework, including an Oklahoma amendment to IRC Section R315.2.2 for permit-triggered alterations, repairs, and additions. That amendment requires covered work to include carbon monoxide alarms located as required for new dwellings.
Local implementation materials, such as City of Norman guidance, show the practical trigger and placement workflow used by code officials for fuel-burning sources and attached-garage risk. This means statewide certainty is strongest in code adoption and permit workflow, while day-to-day execution can vary by local enforcement practice.
Oklahoma compliance files should preserve adopted-code citations, room-level placement records, and final inspection results. Noting local code-edition adoption dates in each compliance packet also strengthens enforcement readiness.

When Are CO Alarms Required?
- Buildings with fuel-burning appliances
- Buildings with attached garages
- New construction
- When building permits are required
- Oklahoma amendment to IRC Section R315.2.2 ties existing-dwelling obligations to permit-triggered alterations repairs or additions.
Where to Install CO Alarms
- Local Oklahoma guidance places alarms outside sleeping rooms and on each story including basement levels used for occupancy.
- Where a fuel-burning appliance is located in a bedroom, local guidance requires an alarm in that bedroom.
For detailed placement guidance beyond legal requirements, see where to place carbon monoxide detectors.
Device Requirements
- Local code guidance in Oklahoma references hardwired with battery backup pathways for new construction.
- Interconnection expectations are applied in local implementation for covered new-work projects.
- Battery-only configurations may be allowed in limited existing-building scenarios depending on adopted code language.
Landlord and Tenant Responsibilities
- The cited statewide sources do not provide one broad landlord-tenant carbon monoxide duty matrix for every Oklahoma rental category.
Enforcement
Enforced by: Local building officials enforce adopted residential code, while OUBCC sets statewide minimum code standards.
Enforcement typically occurs:
- During plan review and inspection for new construction.
- During permit workflow for covered alterations repairs and additions under amended IRC Section R315.2.2.
Penalties for Non-Compliance
No stand-alone statewide Oklahoma carbon monoxide detector fine schedule was identified in the cited code-adoption materials.
Enforcement is typically through local building-code compliance workflow tied to permits and inspections.
Additional Notes
- No standalone statewide CO alarm statute identified as of 2026. Requirements derive from OUBCC administrative rule OAC 748:30 under 59 O.S. 1000.1 authority.
- Oklahoma code compliance is best handled as state minimum adoption plus local enforcement detail.
- Operators should verify the locally adopted edition before finalizing placement and wiring assumptions.

Frequently Asked Questions
Does Oklahoma statewide code require CO alarms in homes?
Oklahoma residential requirements are tied to Uniform Building Code Commission adoption of the 2015 IRC framework and the amended IRC Section R315.2.2 language for permit-triggered work. That gives a statewide legal anchor for covered residential scenarios even though implementation is executed locally. The practical compliance path is to confirm occupancy and permit status, then apply local enforcement guidance for placement and power configuration. Oklahoma property files should include the exact amended section citation and inspection sign-off records.
When does Oklahoma permit work trigger carbon monoxide alarm obligations?
The Oklahoma amendment to IRC Section R315.2.2 specifically addresses alterations, repairs, and additions that require a permit, requiring alarms located as for new dwellings in covered cases. This makes permit classification a key control point before work starts. Teams should coordinate with local code officials early, because scope interpretation can differ by jurisdiction. Oklahoma compliance documentation should tie each project to permit number, amended section language, and final inspection outcome.
Where should alarms be placed under Oklahoma implementation guidance?
Local Oklahoma guidance, including City of Norman materials, uses sleeping-area proximity and story-level coverage concepts that align with IRC Section R315 workflows. It also addresses bedroom placement when a fuel-burning appliance is located in that sleeping room context. Placement should be documented room by room and verified during inspection. Oklahoma operators should retain plan markups, installed-device photos, and inspection comments to support defensible compliance during transfer, leasing, or incident review.
Are Oklahoma landlords given one statewide CO duty matrix?
The statewide adoption sources cited here do not provide one comprehensive landlord-tenant carbon monoxide matrix for every rental scenario. In Oklahoma, residential rental obligations often depend on occupancy type and local enforcement of the adopted code framework. Landlords should verify local requirements at move-in and turnover, then keep written citations in lease compliance files. Documented role assignments for installation, testing, and correction reduce dispute risk and improve inspection readiness. Local policy appendices should identify the authority having jurisdiction for each managed property.
For Oklahoma all-electric homes, which local-code factors can still require alarms?
Not automatically. Oklahoma compliance decisions should be based on adopted trigger language and project context, not only on a utility description. Attached-garage conditions or other fuel-related risk pathways can still create obligations under local code interpretation. Owners should obtain written confirmation from the local authority having jurisdiction before recording any exemption. Oklahoma files should preserve that written basis with permit and inspection records. This documentation is important for later transfer and liability review.
How does Oklahoma compare with Texas for policy design?
Oklahoma in this workflow relies on statewide minimum code adoption plus local enforcement detail, while Texas portfolios often face a different blend of local adoption and occupancy specific statutes. Regional teams should avoid one shared template across both states without trigger-by-trigger mapping. For side-by-side planning, review Texas CO detector laws and compare permit triggers, enforcement channels, and documentation requirements. Oklahoma teams should preserve code-edition notes separately from Texas local-rule references.
