Orange City Council approved a two-hour parking zone along the southern side of Dora Street between William Street and 18 Dora Street in May in response to complaints from residents and Canobolas Family Pet Hospital.

But resident of 37 years Helen Merchant said the signs had not yet been installed, meaning she often struggled to park outside her home.

"The houses at 4-18 have no driveways and our parking spots are taken up with drivers," she said.

"The problem is the ones who park in the morning and don't leave until late in the afternoon."

Mrs Merchant said it meant her outings were restricted.

"Sometimes I can't get my groceries inside because they're too heavy to carry - I know if I go in the morning there won't be a parking spot when I come back," she said.

The pet hospital's Dr Lauren Slater said the business experienced similar problems with emergency vehicles unable to load sick or injured animals and clients having to carry cat cages longer distances.

They said the problem traced back about a year when Centrelink started a call centre in the area.

It has called the site home for about seven years, but moved customer services to Anson Street.

Council spokesman Nick Redmond said the project was added to the list for the signage crew when it was first approved.

"Signs are currently being manufactured and are set for installation in the next four weeks," he said.

"Those who don't have access to off-street parking on their own land will be issued with an exemption pass under the residential parking scheme, which is set to commence within the next eight weeks."

Mr Redmond said approval for Centrelink site was granted in 2009 but its current usage arrangements were unknown.

A Department of Human Services spokesman said about 100 staff worked from the location.

"We have a limited number of private parking spaces as part of our lease arrangement," he said.

"Further public parking adjacent to the site was provided to meet local council requirements.

"We will consult with the local council and the building owner to address any potential parking issues, should they arise."
