No serious complaints were upheld against Brighton and Hove City Council during the last year.
The Local Government Ombudsman received 68 complaints about the authority.
Nineteen were outside his jurisdiction and another 19 were premature complaints which the council should have had a chance to resolve first.
Forty complaints were investigated. In no case had the most serious offence of injustice causing maladministration been committed.
One complaint was upheld with no injustice caused to the resident.
Four were eventually settled locally between the council and complainant.
Thirteen showed no maladministration and nine had not yet been determined.
Thirteen cases were where complaints may not have been fully resolved but the council had not been shown to have acted improperly.
No complaints out of five about councillors were upheld by the council's cross-party standards board.
Council leader Ken Bodfish said: "We have thousands of customers and hundreds of products and services. It is a great achievement to have this few serious complaints against us upheld.
"The really positive news is we had 19 compliments out of the blue. It is a small number but people understandably only get in touch on the relatively few occasions when things go wrong."
