Is monthly disinfection of the building still mandatory?

Not under any rule in force that sets it. The monthly obligation in Disposition 705/DGCONT/15 was revoked by Resolution 35/APRA/19 (Article 3). It remains an offence not to carry out periodic disinfection and deratisation when rodents are found (Law 451, Article 1.3.22).

Does the disinfection certificate expire after 30 days?

That maximum effective period was in Article 5 of Resolution 360/APRA/11, which was revoked in full by Resolution 35/APRA/19 (Article 2). The current rules reviewed set no other validity period for the certificate.

Who pays the fine if rodents are found in common areas?

In a condominium building where rodents are found in the common areas, the fine is imposed on the owners' association (Law 451, Article 1.3.22).

What must the building administrator do?

Look after the common areas and take the steps needed to comply with current rules, including pest control (Law 941, Article 9(b)). It is advisable for the association to set and document the service frequency.

Keep building pest control on track without relying on a repealed rule

Buenos Aires City no longer requires a monthly disinfection certificate for condominiums: Resolution 35/APRA/19 revoked it and no rule in force sets a frequency. It remains an offence not to disinfect and deratise when rodents are found; in common areas the association is fined (Law 451, Article 1.3.22).

For years, condominium associations in the Autonomous City of Buenos Aires had to hold a monthly disinfection and pest-control certificate (Disposition 705/DGCONT/15), and the certificate had a maximum effective period of thirty calendar days (Resolution 360/APRA/11, Article 5). In 2018, Resolution 245/APRA/18 left the frequency to the owners' meeting. Resolution 35/APRA/19, published on 20 February 2019, revoked Resolution 245/APRA/18, Resolution 360/APRA/11 and Dispositions 139/DGCONT/15 and 705/DGCONT/15 (Articles 1 to 3). The City's Official Gazette also lists Decree 8151/80, the rules for pest-control companies, as no longer in force.

Resolution 35/APRA/19 itself states in its recitals that this repeal does not affect the national and local rules that remain in force, including National Law 11,843, the City's Code of Minor Offences (Law 451) and the Building Code. Law 11,843 requires all owners or occupiers of urban property to kill rats and other rodents and to adopt the measures advised by the national health authority (Article 1). Law 451 penalises the holder or person in charge of an establishment or property where rodents are found and periodic disinfection and deratisation is not carried out; in a condominium, if rodents are found in common areas, the fine is imposed on the association (Article 1.3.22).

Law 941 requires the building administrator to look after the common areas and take the steps needed to comply with current rules, including pest control (Article 9(b)). The current rules reviewed set no fixed frequency for building disinfection and no validity period for the certificate; the date to track is the one the association sets or the one in the contract with the company. Water tanks have their own law, Law 6040, covered in the water tank analysis guide.

Who is responsible?

In a condominium building, the holder or person in charge of the property and, if rodents are found in common areas, the owners' association are liable for the offence (Law 451, Article 1.3.22). The building administrator must look after the common areas and pest control (Law 941, Article 9(b)). The national obligation applies to owners or occupiers (Law 11,843, Article 1).

If the deadline passes

If rodents are found in a property and periodic disinfection and deratisation has not been carried out, the holder or person in charge is fined; in a condominium with rodents in common areas, the fine is imposed on the association (Law 451, Article 1.3.22). An administrator's failure to meet the Article 9 duties of Law 941, where attributable to them, is an offence under that law (Article 15(d)).

There is no mandatory monthly certificate today

The monthly certificate requirement (Disposition 705/DGCONT/15) and the certificate's thirty-day period (Resolution 360/APRA/11) were revoked by Resolution 35/APRA/19.
