Sheffield Council has submitted objections to the Government’s proposed changes to planning rules.
Under changes being put forward by ministers, home owners and businesses could extend their properties without permission.
Meanwhile, responsibility for some major planning decisions for big schemes like office and retail parks would be transferred from councils to the Government.
Sheffield Council said that 90 per cent of planning applications are granted after negotiation with planners, the majority within eight weeks.
Coun Leigh Bramall, Sheffield Council cabinet member for business, skills and development, said: “Removing planning controls for extensions to residential houses will do nothing to boost the economy and everything to create anger, resentment and conflict between neighbours.
“We would also lose our ability to plan many major developments in the city.”
