Residential PropertiesReinforced autoclaved aerated concrete (RAAC) RAAC is primarily a building maintenance issue and responsibility lies with the homeowner. To confirm the presence of RAAC, any property suspected of having RAAC requires a survey by a qualified professional which homeowners would need to agree to.Intelligence gathering, undertaken as part of the RAAC Cross Sector Working Group, has indicated that RAAC has not been used extensively as a building material in private sector house building in Scotland. However, some homes containing RAAC have passed into private ownership through Right to Buy transactions and other mechanisms.The Scottish Housing Regulator wrote to all social landlords on 13 October 2023 to request a data return on the presence of RAAC in social sector housing. Additional information was sought from landlords in relation to homes where they have maintenance obligations, provide factoring services, or have previously sold properties.In July 2025, the Scottish Housing Regulator published an update on the number of social landlords that have identified RAAC in their social rented homes. The data returns showed that 17 landlords identified RAAC in 2,205 homes.
