The Connecticut Housing Data Hub is a public resource developed by the Office of Policy and Management (OPM), Department of Housing (DOH), and Department of Economic and Community Development (DECD). Data available on this site includes permitting and demolition data from DECD, housing stock from the American Community Survey, data on affordable housing collected by DOH, and housing market indicator data from RedFin.The dashboard centralizes various types of housing data into one comprehensive platform. It is not all encompassing, as there are still many of pieces of data, analyses, and perspectives that aren’t included here. The goal is to provide a starting point to understand an overview of housing in the state, and we offer resources and data sources for users to further explore the data.The dashboard is updated throughout the year. The data is processed and spatialized using Python and regularly updated in alignment with the underlying datasets. The feature layers and web maps used to create the dashboard are publicly available on the CT Geodata Portal.Key DetailsData Sources Referenced: demolition data from DECD, housing stock data from ACS 5-year, affordable housing data from DOH, housing market indicator data from RedFinData Owner: CT GIS OfficeMap Creator/Data Steward: Sarah Hurley (GIS Office)Update Frequency: Annually (last updated: v2.1 July 2025) For more information and full access to the Housing Dashboard, visit: https://geodata.ct.gov/pages/housing   ;
