Cities and towns; buildings; single-stairway apartment; effective date.

Summary

HB3913 would allow Oklahoma municipalities to authorize single-stairway apartment buildings, even if the city or town has not adopted local amendments to the International Building Code. The bill does not require municipalities to adopt this approach, but it gives them express authority to do so under state law. The authorization is limited to apartment buildings that meet a detailed set of fire and life-safety conditions. Among other requirements, the building could be no more than six stories above grade and not a high-rise, could have no more than four dwelling units per floor, and would need sprinkler protection, fire-rated stair enclosures and corridors, limits on travel distance, specific door-swing and egress design standards, emergency escape openings, and automatic smoke and fire detection tied to occupant notification systems in common areas and exit paths.

Impact

If enacted, the bill would add a new section to Title 11 of the Oklahoma Statutes and expand municipal authority over apartment-building design by expressly permitting single-stairway multifamily buildings under specified conditions. It would affect cities and towns, building officials, developers, architects, and property owners by creating a state-law framework for local approval of a building type that is otherwise more restricted under standard building code practice. The bill would take effect November 1, 2026.

Sentiment

The available voting history suggests limited support in committee: the House County and Municipal Government Committee vote on the bill was 1-4 against a do-pass recommendation. No committee transcript is available, so there is no recorded debate to indicate broader support or opposition arguments. Based on the vote, the bill appears to have faced significant resistance at the committee stage.

Contention

The main point of contention is likely the safety and code implications of allowing single-stairway apartment buildings, a design that can raise concerns about evacuation, fire access, and emergency egress. Opponents may have viewed the proposal as too permissive or as a departure from existing building-code norms, while supporters would likely argue that the bill preserves local discretion and includes extensive fire-protection safeguards. The committee vote indicates that concerns about building safety, code consistency, or municipal authority outweighed support in the committee.
