Mervue United originally operated out of the Redemptorist Grounds before moving to Monivea Road were they shared facilities with Mervue Athletic Club. After joining the Connacht Senior League, the club secured a lease on a clubhouse and a pitch in Fahy's Field. This has remained the club's principal home ground ever since. During the 2009 and 2010 seasons when they were playing in the League of Ireland First Division, Mervue played at Terryland Park as Fahy's Field did not meet League of Ireland standards. The move away from their Mervue fan base affected attendances to the degree that they were the lowest in league records. In early 2011 Fahy's Field was upgraded with fencing and turnstiles been added, allowing Mervue United to play their later League of Ireland games there.
