A relevant and controversial aspect in the modern theory of law in the development of the modern doctrine of the legal system is the question of the intersectoral division of the Russian legal system, the criteria for its construction, as well as the isolation and systematization of legal norms that are complex in nature. The purpose of the article is to establish intersectoral connections, criteria for systematization and the place in the system of Russian law of urban planning norms as a legal community that combines elements of private law and public law influence in the mechanism of legal regulation. A systematic approach and such logical research methods as analysis and synthesis made it possible to determine the place of urban planning norms in the system of Russian law as an independent branch of law with a special mixed type of legal regulation. Scope of application of the results: the main results and conclusions of the study can be used as the basis for the formation of new approaches to building a legal system and criteria for differentiating legal norms. In addition, the recognition of urban planning law as an independent branch of law will significantly facilitate the processes of law enforcement and law-making activities in the urban planning industry. Conclusions: the totality of the subject, method, principles, goals and functions of urban planning norms, forming a special mechanism of legal regulation, indicates the qualitative originality of the regulated sphere of social relations and the isolation of urban planning law as part of the Russian legal system as a branch of law. At the same time, the complex nature of urban planning law by type of legal regulation is due to the interpenetration of private law and public law interests.
