The media still haven't grasped the fact that councils in Dublin, Cork and Galway are mainly responsible for the affordable housing supply shortages;councils' planning rules make it very difficult to increase densities for affordable housing in duplexes and moderately high apartments of up to seven stories high.
These planning barriers are politically motivated and designed to please NIMBY home owners who have a high voter turnout. The NIMBYS don't want any new housing to obstruct the view from their backyard. It's time the national government placed limits on these barriers but that would take political will which has been notably absent for decades.
An article in the New York Times illustrates the NIMBY barriers in California where housing costs are double the US average and lack of affordable housing is causing serious social problems. https://www.nytimes.com/2017/12/01/b...mily-home.html Governor Brown who incidentally is of Irish descent has introduced state legislation to limit municipal government powers to block housing densities.
