Brindabella Christian College must remove demountable classrooms in breach of a development application before Term 1 next year after a community group brought the matter to a tribunal.
The college will also need to correct and update the drawings of its Lyneham campus as part of agreed undertakings made in the ACT Civil and Administrative tribunal.
An association, known as the Community for Constitutional Reform at Brindabella Christian College, argued the demountables which were built without building approval put students and staff at risk.
The group also claimed inaccurate site drawings had affected fire safety on the site.
"The community shouldn't have to take such an active role in ensuring [the school] meets its legal obligations. Regulators need to ensure the community is protected," a spokesperson for the group said.
Brindabella Christian College was contacted for comment.
In 2016, a plan to build a new junior school building on the Lyneham campus was met with community concerns that an increase in student numbers would impact on parking and traffic in Bigalow Street.
The development application was approved on the condition that existing demountable buildings would be disconnected and removed from the site within six months.
However, the college later relocated the demountable buildings to the south east corner of the site and used them as the C Block classrooms between 2019 and April this year.
These demountable buildings did not have building approval.
The Community for Constitutional Reform at Brindabella Christian College raised the issues with Access Canberra and applied for a controlled activity order to be made to remove the demountables.
Access Canberra issued a show cause notice to the school on March 25 asking for a response to the allegations.
Legal representatives for the school said the application should be dismissed and no controlled activity order should be made.
Access Canberra decided not to make a controlled activity order as they determined there was no breach of the development application conditions.
It found these demountables, and another set of demountable classrooms near Brigalow Street, were constructed without building approval.
The community association disagreed with Access Canberra's decision and brought a case against the Territory Planning Authority in the ACT Civil and Administrative Tribunal.
The school was also made a party to the proceedings.
During a hearing on August 22, the three parties came to an agreement that Brindabella Christian College would not use the C Block demountable buildings and would remove them before the first day of Term 1, 2025.
The school must also provide an updated set of drawings of the site to the ACT Planning Authority and the community association within 60 days.
If the school does not comply with these conditions, the tribunal will step in and make controlled activity orders for both actions.
Brindabella Christian College has come under scrutiny from regulators in recent years.
The federal Education Department decided the entity which operates the school, Brindabella Christian Education Limited, was not fit and proper to run a non-government school. Conditions were placed on the school relating to financial management and governance.
Principal Keturah Jones resigned suddenly this term without giving reasons.
