Dublin City Council are investigating noise complaints from residents living near a social housing development on the north side of the city.
The construction site is at the corner of the Schoolhouse Lane and Magenta Crescent in Santry.
The housing charity Tuath is set to acquire the development- which is being fronted by Conor McGregor.
Late Night Noise
Locals say they can't sleep because of sound of a power generator which comes on and off throughout night.
Speaking on 98fm's Dublin Talks today, Fianna Fail Councillor for the area Racheal Batten says she has received videos of the noise.
"I'm getting them at extremely late hours of the night, so they're sending me videos of the the noise.
She added "Certainly, last night. I got one last night at 2.15am; so it is going on through the night."
Councillor Batten said that in the space of a day last weekend, four people contacted her to say they couldn't sit in their back gardens because it was so loud.
Housing charity Tuath is set to pay more than €3million for the development fronted by Conor McGregor.
The mixed martial arts fighter said the houses were for families who currently live in hotels around the capital.
