McInerney Homes was started by Thomas McInerney when he built his first house for a neighbour in
Tulla,
County Clare in 1909. Thomas McInerney and Co Ltd was incorporated for the first time in the late 1940s and later traded under the name McInerney Properties. The company expanded throughout Clare and Galway building homes and schools. These often included social housing developments throughout the west of Ireland and the midlands. By the early 1950s, McInerney had entered the Dublin market and was building high volume suburban homes on green field sites including 190 houses for Dublin Corporation in
Ballyfermot and 340 houses in Milltown. By the mid-1950s, it had expanded into the Greater London market and was soon constructing local authority housing across the South of England. It floated on the Dublin and London Stock Exchanges () in December 1971 and was at that time the largest Irish company to float on the stock exchange. Dan McInerney, one of the senior management figures at the time, was quoted from 1975 as having said, beside being a great social need, housing in Ireland was a leading industry and was like the motor industry in America. The group had an operating profit of €58m in 2007 completing 2,414 units across Ireland, the UK and Spain and was a constituent of the
ISEQ 20. The group then swung to an operating loss before tax of €47m in 2008 only completing 1,359 units. The company celebrated its centenary in 2009 and it estimated that at that stage it had built over 90,000 homes in Ireland. In 2010, the company delisted from the stock exchange having entered examinership. It was then involved in a notable court case
McInerney Homes Ltd v Cos Acts 1990 following its examinership in 2010, however the British arm of the company was sold off to a competitor while the Irish operation was ultimately wound-up. == Notable developments ==
