Kerry Addison said Sheffield Council staff frequently take up three disabled spaces in a car park at Dover Street, Netherthorpe, which causes inconvenience for people with mobility issues who really need them.
The Southey Green woman snapped a picture of a council van she claims was parked illegally this week and shared it with the Sheffield Star to highlight the issue.
The authority has now promised to take action to tackle the issue.
Ms Addison claimed it has been a problem for years and has gotten worse in recent weeks while council staff carried out improvements to railings and street furniture in the area.
She previously described staff who park illegally as "ignorant."
"They need to have regular patrols there."
