Low-income housing in upscale neighborhoods of São Paulo: court rulings increase risks for developers and guarantee full refunds for buyers.

In recent months, the São Paulo courts have been consolidating an understanding that directly impacts the real estate market: buyers of units classified as Social Interest Housing (HIS) and Popular Market Housing (HMP), sold in upscale neighborhoods of the capital, are obtaining contract terminations, refunds of payments made, and, in several cases, substantial compensation.

The legal movement intensified after action by the Public Prosecutor's Office of the State of São Paulo, which questioned the way in which developments classified as HIS (Social Housing) and HMP (Housing for the Poor) began to be offered in upscale areas of the city, such as Vila Nova Conceição, Moema, Vila Mariana, Ipiranga, Perdizes, Pompeia, Barra Funda, and Liberdade.

The practical impact is already clear: the issue has ceased to be merely urban planning or regulatory and has become a significant legal risk for developers, construction companies, and investors.

What is motivating the convictions?

The main basis adopted by the judges is the violation of the duty to inform in the consumer relationship.

In practice, the courts have recognized that, in many developments, the buyer was not adequately informed — in a clear, conspicuous, and understandable way — about the legal limitations that apply to units classified as HIS and HMP.

In several cases, the buyers demonstrated that they only became aware of these restrictions when:

• They appeared at the notary's office to have the deed drawn up; or
• They tried to obtain mortgage financing; or
• They sought to make the rental of the unit feasible.

In other words, when the deal was already substantially advanced.

This scenario has been considered sufficient to characterize a defect in consent and a failure to provide information, with direct effects on the validity of the contract.

What are, in practice, the restrictions that affect HIS and HMP properties?

For the buyer — and especially for those involved in the structuring, incorporation, and marketing of these developments — it is essential to understand that properties classified as HIS (Social Housing) and HMP (Municipal Housing), particularly when benefiting from municipal urban planning and tax incentives, are not equivalent to conventional residential units.

Among the main legal limitations are:

• exclusively residential use;
• Restrictions on sales and rentals to families within specific income brackets;
• The existence of a legal ceiling for the commercialization and rental value;
• Unsuitability for short-term accommodation (such as vacation rental platforms);
• The need for all these restrictions to be expressly stated in the property registration.

In other words, it is a real estate product with its own legal framework, whose economic attractiveness, liquidity, and income potential are significantly different from those of properties on the open market.

Judicial interpretations are becoming increasingly strict.

In one of the most high-profile cases, involving a unit located in the Barra Funda region (case no. 4015132-49.2025.8.26.0100), the court recognized that the consumer was misled and ordered not only the restitution of the amounts paid, but also compensation in the amount of R$ 800,000.00.

This case has since been used as a reference in new lawsuits.

The central point highlighted by the Judiciary is that it is not enough to include technical information in lengthy contractual clauses, ancillary documents, or generic project manuals.

The information needs to be:

• clear;
• highlighted;
• affordable for the average buyer; and
• provided before making a purchase decision.

When this does not occur, the contract becomes legally vulnerable.

Direct impacts for developers, construction companies, and investors.

From a business perspective, recent decisions significantly broaden the legal exposure of developments classified as HIS (Social Housing) and HMP (Municipal Housing), especially when marketed as "traditional" residential products.

Among the main risks observed today are:

• Contract terminations with full or majority refund of amounts paid;
• convictions for material and moral damages;
• imposing contractual penalties against the developer;
• Judicial reduction of retention clauses in contract terminations;
• questions arise regarding the very legality of the commercial strategy adopted.

Furthermore, there is a significant side effect: legal liabilities tend to concentrate after the units are delivered or when the buyer's expectations regarding use and income are not met, which increases the simultaneous financial impact on the project.

What changes for the consumer?

For the buyer, the decisions represent a concrete expansion of protection.

The Judiciary has recognized that a buyer who acquires a unit classified as HIS or HMP without having been adequately informed about:

• price limits,
• income restrictions,
• impossibility of free rental or short-term use,

You have the right to have the transaction reviewed or terminated, with a refund of any amounts paid and possible compensation.

In an increasingly sophisticated market, simply signing lengthy contracts is no longer enough to absolve companies of responsibility.

Conclusion: Transparency is no longer a differentiating factor but a requirement for legal certainty.

The message from these decisions is directed straight to the market.

Projects structured under the HIS (Social Housing) and HMP (Municipal Housing) regimes require a fully integrated legal, urban planning, and commercial model.

The lack of clear and prior communication about product limitations is no longer treated as a formal flaw but is now interpreted as an element capable of compromising the validity of the contract itself.

For developers, construction companies, and investors, now is the time for immediate review:

• of the sales materials,
• from the performance of brokers and sales channels,
• of standard contracts,
• and the market positioning strategy for these ventures.

For buyers, this scenario reinforces the importance of a prior legal analysis before signing purchase and sale agreements involving units classified as affordable housing.

In a regulatory and judicial environment that is increasingly sensitive to housing and urban policy issues, the appropriate legal treatment of social housing and low-income housing projects has become a critical factor for economic viability and the reduction of future liabilities.
