Although the adoption of customization can be a significant differential, it is not easily achieved without a strict management. The customization process of the housing product emerges as an important factor that can add value to the product by considering the requirements of consumers, and this is one of the principles covered by the Lean Construction. This study aims at identifying the offer of customized multilayered buildings in three cities of São Paulo (São Carlos, Mogi das Cruzes e São Paulo) and verifying the interference in the management of the construction site through the application of the Lean principles. Therefore, the methodology chosen was the case study, whose strategy was to apply a questionnaire to six construction companies. The final analysis shows that the companies have found a way of introducing the flexibility in their businesses by planning distinct layouts and different possibilities of alteration. However, only four of them allow the client to modify the internal appearance of the residences. Besides that, even with the restrict knowledge of the Lean concepts in the construction industry, it was observed that all the companies apply the basic tools of this philosophy, albeit in a superficial manner, and have reached significant improvements in the development of their work, enabling them to include the customization in their processes.
