The Dunfield Terrace development was partially destroyed in a fire in the summer of 2022.
People living near the unfinished development told BBC Radio Foyle they are concerned the site is now a magnet for anti-social behaviour.
Last November, the owners of the site were ordered to demolish the area by Derry City and Strabane District Council.
A DCSDC spokesperson told BBC Radio Foyle that the enforcement notice issued by the Environmental Health Department remains in place.
It said its planning department has started enforcement action over the hoarding and the structures on the site.
Council officers have been liaising with the owners of the site.
The council spokesperson said: “We have reminded them of their responsibility to keep the site secure and their commitment to demolish the remaining structures.”
Three years ago building work stopped at the Dunfield site.
Residents’ spokesperson Felicity McCall said a crowd of young people had entered the site on Thursday from where they “hurled half-bricks, concrete blocks, stones and bits of wood” at cars parked outside homes.
She said there is an onus now on council to enforce the site’s demolition.
“We have been saying this for years, but it has become even more urgent,” she told the BBC.
Police Derry City and Strabane have appealed to anyone who witnessed the latest incident, which happened at about 8 pm on Thursday, April 13, to contact them on the 101 number.
