Three others also wrote to the council, calling for the application to be rejected, with one arguing the “noise and late-night disturbance” would not come to an end when the event finishes.
“Music, amplified sound, large crowds, shouting, vehicles, taxis and people leaving the stadium can all result in disturbance continuing well into the early morning,” the resident wrote.
Another resident with young children said the event running into the early hours of the morning would “cause absolute chaos for those of us living right next to it”.
The person said issues such as “shouting and singing” early in the morning would “completely wake the whole house up and leave us with exhausted, stressed children”.
Others wrote in support of the licensing conditions being granted, with one saying they believed the event would bring a “significant economic boost” to businesses in the city.
Another said the event could help bring more tourists, particularly from the United States, to Cardiff.
One of the most eagerly awaited bouts in recent boxing history, numerous venues were put forward when the fight was proposed, including New York’s Madison Square Garden.
However, focus shifted to the UK after Joshua and his promoter Eddie Hearn refused to budge on their contractual right to stage the fight on British soil.
Wembley Stadium was touted as a potential venue – with London Mayor Sadiq Khan urging promoters to get in touch – but its strict 23:00 event curfew proved an issue given Netflix’s preference to broadcast during prime time hours in the US.
In Cardiff, while early-hour finishes require extensive co-ordination around transport, policing and crowd management in the city centre, the venue already holds a precedent for late-night boxing.
In 2007, Joe Calzaghe’s super-middleweight unification victory over Mikkel Kessler did not start until 02:00 local time to satisfy US television network Showtime.
The stadium’s application for the variation of the licence has been made according to the Licensing Act 2003, with a 28-day consultation period allowed.
Representations can be made to object to or support the proposals around prevention of crime and disorder, public safety, public nuisance and protection of children from harm.
If objections are received, the council’s licensing sub-committee must meet to hear them, and “may modify the conditions of the licence or reject the whole or part of the application”.
The Principality Stadium has been asked to comment.
