The National Building Control Office (NBCO) provides and manages the system for Building Control administration in the 31 Building Control Authorities (BCMS). Under the objectives of the Public Sector Data Strategy 2019-2023, NBCO has developed a secure Open Data Portal for our data. Access to quality data on housing development, building activity and completions is a key requirement for effective decision-making and the NBCO is now making our data available to all stakeholders at the same time to support evidence-informed decision making on all forms of development. This will contribute to the development of a single Data Ecosystem for Ireland’s policy makers, civil servants, business owners and the general public. In collaboration with Local Authorities and Ordnance Survey Ireland (OSi), we will continue this work to develop a geospatial functionality that plugs our data into the OSi geospatial data hub (called ‘geohive’).
