A Cannington resident said she was disappointed the council had supported a motion to approve a property change from a residential block to a childcare centre.
The council voted to support the change at its last meeting, which would change the property on Doust Street from a residential lot to a childcare centre.
It would be allowed a maximum of 30 children and have a small car park for pickup and drop-off.
The city also required a 1.8m brick fence be built on three sides of the property in anticipation of increased noise levels.
Pat Howarth lived near the site and said the council had not listened to local opposition to the proposal.
“Everybody sent letters around here as far as I know and nothing’s been done,” she said.
“It’s just gone ahead.”
Ms Howarth said the location between two residential properties was an unusual place for a childcare centre and could have repercussions for property values in the area.
She said the decision had angered her.
“It’s going to take the price away from properties. People are not going to want to buy a house next door or next but one from a childcare centre.
“Children make noise. I’m not against children making noise, but I don’t want to hear kids screaming and carrying on all day from 7am on my property.”
The city said it had taken on recommendations by an acoustic consultant who visited the area and identified noise could be managed to meet regulation requirements.
It said it had received 33 objections and 47 “no objections” during the advertising process.
Mayor Paul Ng said the property values were not a consideration for the council to make.
“The perceived impact on property values, which is difficult to substantiate in any case, is not a consideration the city can take into account when making planning decisions under legislation,” he said.
