The project factor complemented the value given to a house analyzed in real estate appraisals. In this work, the design of the functional analysis methodology of the rooms that make up each dwelling was presented, in combination with the Ross-Heidecke physical depreciation approach. The architectural plans of samples of houses in Mexico of all socioeconomic categories were measured and three types of matrices were established for their valuation and percentage parameters. The main type of construction was analyzed under the analysis scheme by building items and the rest of the types were examined in a unitary manner. The percentage results of the sampling analysis were directed to matrices of physical focus and as a whole; with the qualification factor of the state of conservation of each building item, with the calculation of a project factor appropriate to each type of dwelling. The automated analysis, which qualified the value of the buildings based on the functionality of each architectural project, complemented the study of physical depreciation. The resulting percentages of the sample, calculated how much each room measures in the logic of a simulation, which according to the total building area and the specific number of rooms, classified the functionality to unit surfaces. It was emphasized that the functionality analysis includes the qualification of facilities and infrastructure. The result of the functionality factor of the architectural project was subject to the parameters and requirements of residential building codes in Mexico.
