Event security concepts: legal duties in Vienna

This article provides a practical overview and is not legal advice. For a binding assessment of your specific event, contact the responsible events authority or legal counsel specialising in event law.

When a security concept becomes mandatory

Vienna’s Event Venue Ordinance requires an officially reviewed security concept above a certain visitor count, depending on the type of venue, escape-route situation and how it’s used. As a rough guide: the larger the expected audience and the more complex the venue — multiple levels, restricted escape routes, outdoor areas with tent structures — the more likely a concept is required. Only the responsible authority or legal counsel can give a binding assessment; as an event security provider, we check this together with our clients as part of the quote process.

What a security concept must include

A complete security concept typically covers:

• Staffing calculations for stewarding and security, based on visitor count and risk profile
• Escape-route planning and signage, matched to the venue
• First-aid and medical provisions, including a dedicated medical team for larger events
• Access and entry control, particularly where alcohol is served or age restrictions apply
• Coordination with police, emergency services and the responsible events authority
• An emergency procedure for evacuation or medical incidents

Who is liable if something goes wrong

Responsibility for submitting and complying with the security concept rests with the organiser. The contracted security provider carries out the concept operationally — through access control, patrols and stewarding — but is generally not liable for the official approval itself. That’s exactly why early coordination pays off: an experienced security provider spots typical weak points in a concept before the authority flags them.

Timeline: how early should you start?

For events requiring a security concept, we recommend at least two to three weeks’ lead time, depending on the venue’s complexity and the authority’s response time. Smaller, informal events without a concept requirement can be planned at short notice. For recurring annual events, such as Christmas markets or city festivals, a longer-term framework agreement is also worth considering, simplifying coordination with the authority in following years.

Common mistakes in staffing planning

A common mistake is calculating staff numbers purely from expected visitor count, without accounting for entry flow, escape-route width, or specific risks such as alcohol service or high-profile guests. A second common mistake: booking security staff only shortly before the event, which leaves no time for a proper site walkthrough or coordination with authorities and other service providers.

Interaction with other approvals

A security concept rarely stands alone. Depending on the type of event, you may also need a trade licence for alcohol service, a road-use permit if you’re using public space, or a separate fire-safety sign-off from the fire brigade. These approval processes often run in parallel and should be coordinated early, so the security concept isn’t developed in isolation from the other requirements. As a security provider, we coordinate directly with the other bodies involved where needed, to avoid duplicated work.

Cost of the security concept itself

Developing a security concept involves its own planning effort on top of the actual staffing cost for the event day — depending on the venue’s complexity and the number of authorities to coordinate with. For recurring events at the same venue, this effort pays off over several years, since a base concept that’s already been developed and accepted by the authority usually only needs adjusting rather than rebuilding from scratch.

Plan post-event cleaning too

An often-overlooked point in event planning: the venue needs to be usable again quickly after the event. Post-event cleaning is handled by our WG Dienstleistungen brand — often overnight, straight after the event ends, so the venue or public space is ready again the next day.

Smaller events: what’s still worth doing

Even where no official security concept is required — a company party or a smaller trade fair, for example — a simple internal risk assessment is worthwhile for events with public footfall: how many visitors are expected, are escape routes clear and accessible, will alcohol be served? This informal check costs little time and noticeably reduces risk, even without a formal concept.
