Understanding Rural Housing Policy in County Galway
Under the Galway County Development Plan, applications for rural standalone homes outside town boundaries require demonstration of 'Local Housing Need' (e.g., individuals born/raised in the local area or farming families). If you do not meet local rural criteria, building a 45m² exempted extension or garden suite on an existing family property is often the fastest, most straightforward solution.
