The provision of social housing is, in the first instance, a matter for individual local authorities.
My Department collates statistical information on a quarterly basis from Local Authorities in relation to delivery outputs across all social housing delivery streams. Details on the number of social housing properties constructed or acquired by local authorities, to the end of Quarter 1 2019, are published on my Department’s website at the following link: www.housing.gov.ie/housing/social-housing/social-and-affordble/overall-social-housing-provision. These statistics are updated on a quarterly basis, with similar details for the remaining quarters for 2019 to be published as the year progresses.
Leasing data for Mayo for the years 2011 to 2013, on a cumulative basis, and from 2016 to end Quarter 1 2019 are also available at the above weblink. The number of social housing homes delivered through leasing in Mayo in 2015 was 45 and 31, respectively.
Given the number and type of houses involved, information on the individual costs per property are not readily available but may be available directly from the local authority.
