This research is an applied one with a descriptive – analytic method was conducted in Jahrom with the objective of analyzing the effective factors on retrofitting of rural homes. Our statistical universe includes 11 villages of Simekan district in the suburbs of Jahrom County, these villages have taken a loan over 50 items from Housing Foundation. For estimating the sample volume at rural family level, by using Cochran sampling method with 95 percent accuracy, the number of 186 persons (family guardian) was questioned by simple random sampling method. Then, the necessary information was gathered by survey and questionnaire. Based on the results of factor analysis, among the first two factors in the order of effectiveness proportion, the first factor (satisfaction with rural homing) describes 57.455 percent of variance by itself and the second factor (homing retrofitting) is accounted for 20.835 percent of variance. Also, it was found that the best reason for retrofitting of rural homes is using of rural homing facilities (67%). Safety against natural disasters such as earth quake and flood (33%) is another reason for homing retrofitting, so our main hypothesis is supported. According to the results of hypothesis testing, based on Pearson correlation coefficient and regarding to variance testing and our significance number which is more than 0.05, there isn’t a significant difference between our independent variables (gender, age & education) and housing retrofitting.
