The purpose of the study is to identify and compare territorial zones, volumetric-spatial characteristics of buildings and the peculiarities of the formation of open public spaces in Zelenodolsk. The main results of the study are that a comprehensive urban planning analysis was carried out, on the basis of which the features of the formation of territorial zones in the city were revealed, the boundaries of spatial-environmental morphotypes, their environmental features were identified, and the specificity of the formation of a design code for different areas of the city was determined. The significance of the results obtained for architecture and urban planning lies in the fact that the concept of the form-based code developed in the study for Zelenodolsk can become the basis for updating (or updating) urban planning documents (Local standards for urban planning, General plan, urban planning regulations, City beautification rules). The method of identifying and forming spatial-environmental morphotypes in the city is also of great importance, as the basis for creating a form-based code for Russian small and medium-sized industrial cities
