IT could cost up to $10,000 to fix the old Tintenbar Council Chambers at Alstonville after a car crashed into the building earlier this month.
The heritage-listed building is now home to Arts Northern Rivers and Accessible Arts.
A new business also recently moved into the building.
But the front veranda sustained major damage in the accident and it is not yet known when it will be fixed.
The roof, balustrades and gardens were also damaged.
The council undertook immediate remedial repairs and actions to ensure the site was safe. Staff are now in the process of getting quotes to repair and restore the building.
At this stage it is estimated the repairs could cost up to $10,000.
Arts Northern Rivers chief executive Peter Wood said it was lucky there was no structural damage.
"It's such a beautiful old building," he said.
"We love being in this space because of its history.
"To see the front of it looking like this is a shame. This is our public face; it's what people see when they drive past or come to visit.
"I was shocked when I was told this had happened.
"It will be nice when the building is back to looking the way it should.
"But at this stage we just don't know when that's going to be.
"Apparently there are some insurance issues which need to be sorted out before any work can be done on the building.
"And because it's heritage listed, the work has to be done in accordance with that.
"We are just hoping the insurance issues will be sorted out as soon as possible."
Zoe Robinson-Kennedy from Arts Northern Rivers was at the scene the day after the accident happened.
"It looked pretty crazy, with bits of the car scattered around everywhere," she said.
"We had these two huge pot plants which were just completely shattered.
"It's really lucky that the driver wasn't hurt and that there wasn't more damage."
The building was used as the council chambers by Tintenbar Shire Council before it amalgamated with Ballina in 1976.
