SrO

SRO most commonly stands for standing room only, a designation used at venues to indicate that all seats are sold or unavailable and attendees will stand for the event. SRO tickets are often offered at a lower price, but standing conditions can affect accessibility and comfort. The term originated in theater and concert contexts and remains in use for sold-out performances and some crowdsourced events.

In housing policy, SRO stands for single-room occupancy, a form of rental accommodation consisting of a single private room with shared kitchen and bathroom facilities. SRO units are used to provide low-cost housing in urban areas with high housing costs and shortages. They may vary in quality, tenant protections, and regulatory status, with some modernized buildings and others subject to maintenance and safety concerns.

In financial regulation, SRO means self-regulatory organization, a non-governmental body authorized to supervise members of a profession or industry and enforce rules. In the United States, examples include FINRA and some stock exchanges that operate as SROs under SEC oversight. SROs establish conduct rules, monitor markets, license members, and impose disciplinary actions for violations.

Because SRO has several distinct meanings, the intended sense depends on the context.
