Quick answer
Authorization Permit for events in São Paulo, in a few lines
In São Paulo, a public, temporary event with more than 250 people, with or without ticket sales, requires City Hall's Authorization Permit (Alvará de Autorização), under Decree 49.969/2008. The application goes to the Municipal Secretariat for Urban Planning and Licensing at least 30 days in advance, with an occupancy calculation, approvals from other agencies and technical attestations with ART for the stage, structures and installations; an event with a fenced-off area also needs the Fire Department license, requested separately. An event without authorization is fined per square meter of land. MTC analyzes the venue, prepares the technical part with engineers and architects and follows the application through to the permit.

What the Authorization Permit for events is
The Authorization Permit (Alvará de Autorização) is São Paulo City Hall's license for a public, temporary event with more than 250 people, with or without ticket sales: a concert, party, fair, conference, religious or sports event. It applies to public or private property, a lot, a parking lot, a street, a square or a park (Decree 49.969/2008). The application goes to the Municipal Secretariat for Urban Planning and Licensing, which reviews the event's safety conditions.
The application must be filed at least 30 days in advance, and filing alone does not authorize the event. The Zoning Law sets a fine of R$ 20 per square meter of land for an event without authorization, a 2016 value adjusted by the IPCA, and the permit can be revoked at any time. At the Fire Department, holding a temporary event without a license is a very serious violation.
What usually holds things up is the technical part: occupancy and exit calculations, the safety design, approvals from CET and the Health Department, and attestations with ARTTechnical Responsibility Record (Anotação de Responsabilidade Técnica). A CREA record that identifies the engineer responsible for a project, technical report, or construction work. for the stage, roof structure, bleachers, electrical installations, grounding and lightning protection. And City Hall's requirements allow only 5 days for a response. MTC analyzes the venue, puts together the technical documentation with engineers, architects and partners, and follows the application through to the permit.

Does your event need the Authorization Permit?
The decree sorts cases by audience and by venue. It is the first check MTC does, before the date and the venue contract are closed.
1Up to 250 people
Outside the Authorization Permit. In a street or square, use of the space is authorized by the local Subprefeitura.
2More than 250 people on a lot or in a parking lot, warehouse, street, square or park
Authorization Permit from City Hall, requested at least 30 days in advance.
3Assembly venue with a valid Operating Permit, only in the licensed areas and without changes
Exempt from the Authorization Permit, as long as maximum occupancy is controlled.
4The same licensed venue, but with a stage, tent or bleachers set up for the event
It loses the exemption and needs the Authorization Permit.
5Audience also in the courtyard, garden or parking lot
It needs the permit. In the parking lot, the event cannot take up the building's mandatory parking spaces.
6The activity will continue beyond the 6 months and the extension
The person in charge is notified to apply for the venue's Operating Permit.
An event with a fenced-off area also needs the Fire Department license, requested separately. MTC checks both paths when analyzing the venue.

See all questionsThe Authorization Permit is required for a public, temporary event with more than 250 people, with or without ticket sales, on public or private property, a lot, a parking lot, a street, a square or a park.

Source: Decree No. 49.969/2008 (Authorization Permit for events, arts. 5, 24 and 42) (opens in a new tab)It does not need City Hall's Authorization Permit. But an event in a street, square or other public area depends on authorization from the local Subprefeitura, which has its own rules. In Pinheiros, for example, the request is filed at least 30 days in advance.
Source: São Paulo City Hall (Subprefeitura Pinheiros): authorization for events in public areas (opens in a new tab)At least 30 days before the event date.
