Broughton Town Council is objecting to a planning application to extend the Riverside doctors' surgery on Brooklands Avenue.
Approval is being sought by the practice from North Lincolnshire Council to change the use of a domestic garden to form an extension and provide additional car parking.
But Broughton Town Council objects "due to insufficient parking for patients as a result of the extension."
North Lincolnshire planners gave people a chance to comment on this application until October 11, but no members of the public chose to do so.
The unitary authority will now decide whether to accept Riverside Surgery's application.
