Parepare City, in South Sulawesi Province, has a population growth rate of 2.2% every year. Population growth requires land for settlements.  The high demand for land for settlement development needs to be anticipated to avoid inconsistencies in the spatial plan and changes in land use functions. One of the causes of high land-use change and discrepancies in Regional Spatial Plans (RTRW) is the lack of information about land suitability for settlement development. This article aims to build a GIS-based information model for the appropriateness of the settlement development in Parepare City for self-built housing people of Parepare. The method used is the spatial analysis of overlay spatial and scoring data using software (GIS).  While to find out the perceptions and social interest carried out data retrieval by interviews and the spread of questioner interviews conducted with the government. And the questionnaire distributed to 355 residents. The results of this study showed that the density of settlements concentrated in the city center.  The settlement area shifted to suburban areas which caused land conversion. The forest area of 3,055 hectares in 2010 decreased to 2,971 hectares in 2014, and the paddy fields decreased by 837 hectares, while land for settlements increased to 923 hectares in 2015. This website GIS-based model can show the distribution of space that suitable for the allocation of settlement area following the carrying capacity of the environment and the Regional Spatial Plan of Parepare City. Digital database produced for urban spatial growth and land transformation by integrating GIS with websites. This model of settlement development based on GIS websites is expected to be a reference for people in making decisions about their housing/settlement locations. Further, this model could be as tools to anticipate the adverse effects of the inconsistency of the RTRW in the Parepare City.
