Commercial Rent Increases in Brazil: Market Value Shifts

Governed by the Lei do Inquilinato (Law No. 8.245), which was published on 21 October 1991 and entered into force sixty days later, commercial rent in Brazil is primarily a matter of contractual agreement. While adjustments are common practice, the 3-year mark is when parties can legally seek to align the rent with market reality through judicial intervention if they cannot agree.

Unlike commercial markets in some jurisdictions where corporate landlords have unilateral freedom to escalate rent based on lease agreements, the fundamental tenancy laws of Brazil emphasize mutual agreement and free convention.

Rent Convention and Adjustments

For the vast majority of commercial properties—ranging from corporate offices in Faria Lima to massive distribution hubs on the outskirts of São Paulo—the base monthly rental price is determined by free convention between the parties (Art. 17).

Under Law 8.245/91, there is no explicit statutory requirement for a 12-month freeze; rather, the law permits the landlord and tenant to fix new values or modify adjustment clauses at any time through mutual agreement (Art. 18). Any attempt to unilaterally escalate rent outside of the terms established in the contract or by mutual consent is subject to legal challenge.

Tying Increases to Inflation Indices: IGP-M and IPCA

When parties agree to periodic adjustments, they often tie the rent hike to an official Brazilian macroeconomic index. While Law 8.245/91 does not mandate the use of a specific index or frequency, it is common practice to use metrics such as:

• IGP-M (General Market Price Index): Historically the dominant "rent inflation index" computed by the FGV. However, because its formula factorizes global commodity prices and the dollar exchange rate, it often results in volatile increases for businesses.
• IPCA (Broad National Consumer Price Index): The official government retail inflation index. In recent years, many corporate tenants have demanded tying their leases strictly to the IPCA, which tends to reflect a more stable domestic inflation rate.

It remains a legal violation under Art. 17 of the Tenancy Law to tie base rent to foreign currencies (such as the U.S. Dollar or Euro) or the minimum wage.

"Percentual Rent" and Shopping Center Freedoms

While street front retail and large warehouses are generally governed by fixed base rents and agreed-upon raises, Shopping Centers (Malls) enjoy sweeping liberties under Article 54 of the Tenancy Law.

Malls essentially operate as private commercial ecosystems. Shopping Center management is legally permitted to charge their tenants a hybrid rent model: A fixed "Minimum Base Rent" plus a variable component known as the "Percentual Rent" (aluguel percentual).

This percentual rent legally entitles the landlord to a dynamic slice of the tenant's gross monthly sales. If a clothing store has a massive boom in December sales, the mall's percentual rent slice increases accordingly for that month.

The 3-Year Revisional Action (Ação Revisional)

Because decades can pass in commercial real estate without the lease fundamentally changing structure, the Tenancy Law created the Revisional Action under Article 19.

Every 36 uninterrupted months (three years) since the last negotiated base rent or contract signing, if the parties cannot reach an agreement, either the corporate landlord or the commercial tenant can petition a civil judge to adjust the rent to reflect the "True Current Market Value" of the property.

• Landlord Advantage: If massive urban developments caused the area's commercial value to skyrocket over three years, the landlord may sue to force a market-rate rent hike.
• Tenant Advantage: If the neighborhood degraded and the tenant is overpaying compared to equivalent nearby properties, the tenant may sue to force a deduction in rent.

These lawsuits often entail judges appointing temporary injunctions setting interim rent amounts until market appraisals can be fully litigated.
