There have been a significant difference between the urban spaces of the pre-Islamic and contemporary periods in Iran, which is resulted from organized complexity. This complexity has occurred in an open system and its components (fractals) have ben formed with a logic over time resulting in an internal development in an urban system with a hidden order in the urban chaotic space. In the traditional  urban areas , a hidden order in the urban space organized urban development within a defined boundries . People’s participation in achieving this important issue has played a crucial role, which is among the most important issues in urban sustainability. The present research, with documented and comparative studies applying chaos theory (fractal geometry, fuzzy logic and chaos space) as a systematic theory, aims to analyze the factors of dynamism, complexity, nonlinearity, hidden order, space self-organization, which is among the characteristics of a chaos space and living system, in urban structure and traditional  Islamic architecture such as privatization laws, public laws and Islamic inheritance laws in order to recognize the hidden order in ancient cities, inconsistency of contemporary cities developed in unspecified bounds by achieving a definite definition of consistency and integration. Finally, the paper introduces endogenous growth and people’s participation, which are resulted from Iranian-Islamic culture and world view in urban life aspects in a living system instead of specialization in the direction of urban stability and architecture.
