City Hall of São Paulo establishes a limit for construction noise; see what changes – 9/28/2021 – Daily life

The City of São Paulo published this Tuesday (28) rules that create limits for noise in civil construction works in the city.

Until now, the city did not have a clear regulation regarding the noise of construction works in the city. With the new rules, the hours and decibels allowed in civil construction works were established — public works are not included.

The measurement of noise pollution must be carried out by means of a sonorometer by agents of the PSIU (urban silence program). In case of irregularities, there may be a fine and even closure of the work.

According to the decree signed by Mayor Ricardo Nunes (MDB), works subject to an execution permit may have noise limits of up to 85 decibels between 7:00 and 19:00. From 7:00 pm to 7:00 am, it drops to 59 decibels.

On Saturdays, from 8 am to 2 pm, the limit is 85 decibels; from 2 pm to 8 am on Saturdays, Sundays and holidays, the limit goes to 59 decibels.

Despite establishing these limits for private works, there are a number of exceptions, including the government itself.

Public works are excluded from the rules, as well as those relating to the earth moving, foundation, demolition and structure phase, as long as they are carried out in the period between 7:00 am and 7:00 pm.

Civil construction loading and unloading activities are also excluded, as long as they are carried out from 9:00 pm to 12:00 am, Monday to Friday. Furthermore, emergency works are still allowed regardless of the noise.

Failure to comply with the rules results in a series of fines, which increase as there is a recurrence. In the third assessment, the embargo of the work in question will be carried out.

In the event of disrespect for the embargo on the works, a police inquiry will be instituted, in addition to the new closing of the work. Requests for disembarkations will be analyzed by the PSIU.

According to the city, the decree will take effect after 90 days. With this, the private sector will have time to adapt to the new rules.

Currently, PSIU’s work is not focused on construction noise, a constant complaint from São Paulo residents. Regulation changes that.

The agency was already responsible for dealing with reports of noise in commercial establishments, loud vehicles, funk dances, religious spaces, demolitions and quarry detonations.

The service does not respond to noise from food trucks and food stalls on the streets, noise from homes and various festivities as long as they take place with authorization at the defined time.

With the reopening of several economic sectors, complaints of noise rose again in the city. In the second quarter, complaints to the PSIU rose 48.6% — going from 2014, in the same period last year, to 2,993.

The five districts with the most occurrences are Sé (130), Vila Leopoldina (75), Tremembé (67), Sacomã (65) and República (64).

Calls, however, have not yet reached the same level as the second quarter of 2019—compared to it, the second quarter of 2021 had a 37% drop.

There was also a slight increase in the occurrences of disturbance of quiet, in general, related to noise in homes. Also in the second quarter, the occurrences of the type increased from 5,775 to 5,958, according to city hall data, an increase of 3.2%.

In these cases, the districts with more occurrences are all outside the expanded center, on the edges of the city. The five regions with the most cases are Cidade Tiradentes (245), Cidade Ademar (176), Campo Limpo (151), Capão Redondo (148) and Itaquera (147).
