Tenants have also complained about finding broken glass, vomit and urine near the flats, she said.
''I shouldn't have to hire my own guards for my own properties on nights the bar is open to 1am.''
The problems were not new and had persisted under the bar's former owners and Ms Seque said she did not believe they would be solved under the new ownership.
A district licensing committee hearing on the matter is set for May 13.
Association chief executive Debbie Downs said changes would be made to the bar's procedures and physical modifications added to the outdoor area to address Seque's concerns.
Both police alcohol harm prevention officer Sergeant Ian Paulin and the medical officer of health Toni Paterson have opposed the application as it asks for closing hours of 1am on Thursday, Friday and Saturday nights, outside the allowed hours for suburban bars in the local alcohol policy.
The bar is one of seven which have opposed the new closing times set under the policy and a decision on that matter is likely to be released this week.
Paulin had no other objections to the application and said the association was impressive in all aspects of running the bar.
