The Brazilian Constitution dated 1988 promoted a notable transformation of the jurisdictional order. It submitted not only the Civil Code but all the nonconstitutional normative to be in accordance to the Constitutional values and principles. This methodology, entitled Civil-Constitutional Law, changed in a qualitative manner the foundation of the traditional private law, subtracting the center of the ordainment concerns of the individual interests of the patrimony, replacing it by the protection of the human rights. This study intends to present this phenomenon and in good conscience of its use, be able to analyze intricate cases of the rental relationships, offering solutions guided by the axiologicalteleological of the Civil-Constitutional Law. The parts for debate are: the needed dialog between the Consumers Code, the Tenant Code, the Civil Code and other non constitutional laws; the potential anti-juridical possibility of previous renouncement of the landlord to its legal right to be compensated for the repairs needed; the abuse of an unmotivated denounce of the rental contract as a way to accomplish illegal objectives. This study aims to present an hermeneutic that pays attention to the Constitutional Right to Housing, enriched with meta-individual and existential interests, as in the Constitutional Rights to Housing, as a form of reassuring the necessity to the functionalization of the entitled and to avoid the susceptibility of the tenant figure as a concrete person, possessed of dignity.
