Anthony Flynn, a Dublin city councillor and homeless campaigner, will be laid to rest on Tuesday after he passed away earlier this week.
The 34-year-old was found dead at his home in East Wall on Wednesday afternoon.
Mr Flynn founded the housing charity Inner City Helping Homeless in Dublin city centre in 2013.
Originally from Dorset Street, Mr Flynn was selected as councillor in the 2019 local elections as an Independent north inner city candidate.
He was a vocal opponent of the government's housing policy, and was appointed to the Dublin City Council Housing Special Policy Committee alongside the Joint Policing Committee for Dublin City.
Mr Flynn was also appointed chief executive of Inner City Helping Homeless in 2019 but had recently been suspended pending an investigation by gardai into allegations of sexual misconduct. However, he had not been arrested or formally questioned.
A lantern vigil is being held outside the offices of the charity on Dublin's Amiens Street on Friday night in tribute to the campaigner.
In a statement following his death this week, ICHH said: "We are broken hearted to say we were notified of the death of our co-founder of Inner City Helping Homeless, Anthony Flynn.
"This tragic loss is a source of deep shock to all of us at ICHH. We wish to express our sadness and deepest condolences to his family and friends at his sad passing.
"Anthony was a person who passionately cared about the plight of the homeless and fought to give them a voice and a home. As one of the founders of ICHH, he turned that belief into action.
"Anthony’s passing is a tragedy and we are all joined in expressing our condolences to Anthony’s family, friends, and colleagues.
"ICHH is committed to continuing the necessary work begun by Anthony."
His family are said to be "heartbroken" following his death, and he will be laid to rest on Tuesday in Dublin city centre.
Mr Flynn's obituary on RIP.ie reads: "Flynn (Dorset St, Dublin 1) - Aug 18, 2021, (unexpectedly) Anthony (Anto), dearly loved only son of Yvonne (nee Hanney) and the late Anthony (Anto), grandson of the late Christopher (Boy) and Nellie Hanney and Brendan (Mousey) Flynn, most treasured brother of Anita, Lisa and Andrea, cherished uncle of Callum, Ariana, Dawson, Harper, Tristan and Ralph.
"Anthony will be deeply missed by his heartbroken mother, sisters, brothers in law, nephews, nieces, step dad Damien, step sisters Michelle, Tammy and Gemma, nanny Lolo, uncles (especially Greg, who guided him and who he looked up to like a father), aunts, cousins, extended family, a wide and large circle of friends, his colleagues in ICHH, all those he helped through homeless services and Dublin City Council."
A private funeral service will be held on Tuesday morning at 10.30am in The Church of Our Lady of Lourdes, Sean McDermott St, for family and close friends, with a limit of 50 people, followed by burial in Dardistown Cemetery.
Following the Mass, his funeral cortège will follow the route past Lloyds Bar and the office of ICHH, with neighbours and friends welcome to line this route in a socially distanced manner to pay their respects.
