A considerable share of dysfunctions in the social, economic, physical–functional, and decision-making systems of deteriorated urban fabrics in many countries, including Iran, originates from the absence, weakness, or inadequacy of laws and regulations. These instruments, designed to guide legislators and urban decision-makers in controlling development, promoting social justice, and ensuring a safe and livable environment, often fail to achieve their intended goals due to shortcomings, contradictions, or conflicting objectives. Qazvin, chosen as the case study for this research, is one of Iran’s historic cities and a pioneer in urban planning. Nevertheless, its deteriorated urban fabric is of particular importance given its scale, proximity to heritage assets and valuable urban spaces, and the severity of its physical and social challenges. This study examines the existing laws and regulations, their impacts on physical–functional, socio-cultural, economic, decision-making, and environmental–natural systems, and evaluates their influence on the regeneration of Qazvin’s deteriorated urban fabric. The research pursues two main objectives: (1) to address or mitigate problems arising from the enactment or implementation of relevant laws and regulations, and (2) to identify potential solutions to enhance their effectiveness. To achieve this, impact analysis techniques were employed alongside the Delphi method to propose strategies for improvement. Findings highlight the crucial role of laws and regulations in urban regeneration. Drafting such frameworks requires a comprehensive, multidimensional approach grounded in the needs of residents. Success depends on active community participation, the application of appropriate analytical tools, and collective decision-making to address the intertwined physical, social, economic, and environmental dysfunctions of deteriorated areas.

The architecture of the first Pahlavi period is considered a turning point in the evolution of Iranian architecture and urban planning, which dates back to the Qajar period and the familiarity of the Shah and his courtiers with European architecture. These changes reached a more tangible level in the first Pahlavi period, marking the beginning of modern Iranian architecture. The present study examines the architecture of schools from this period, focusing on a comparison between schools in East Azerbaijan and other modern schools in Iran, to provide a model for the design of today's schools. This study aims to analyze qualitative findings including: physical, spatial, and functional organization used in schools of the first Pahlavi period, such as appropriate access, spatial connections, hierarchy, arrangement of spaces, combination of full and empty space, open and semi-open spaces, introversion and extroversion, geometry and pattern, ., to arrive at solutions for the development of school architecture. The methodology of this research is historical-interpretive and case study (study of 6 schools from the Qajar and Pahlavi periods in East Azerbaijan province). The research method employed is qualitative, involving interviews with experts. In this study, 10 people were interviewed. In accordance with the principles of grounded theory, data collection and analysis were conducted following the first interview. This study also conducted a comparative analysis of the architecture of East Azerbaijan schools between 1304 and 1320, examining six landmark works in this province. Using the comparative method and structural approach, the spatial organization of schools from the Pahlavi period was analyzed, categorized, and coded. The results showed that the highest salience in the functional component was associated with extroversion, with a value of 28, and the lowest was associated with introversion, with a value of 7. The results indicate a decrease in Iranian-Islamic identity in Pahlavi-period schools. These changes include the shift from traditional architecture to new styles, the transformation of interior to exterior space, the reduction of hierarchy and proportions, the decline of decorative elements, and the elimination of green spaces.
