Cambabest, a lightside merchant based in Venetia Road, Bordesley Green, was ordered to pay out more than £8000 after failing to ensure the safety of its employees.
The company, which employs 50 members of staff, repeatedly ignored the health and safety orders regarding its site and equipment, Birmingham Magistrates Court heard.
A routine inspection by Birmingham City Council health and safety officers revealed badly damaged ladders, unstable wooden stairs, and an unprotected two-metre high timber store roof.
Although no accidents had been reported, the company was given a £6000 fine and told to pay more than £2000 costs.
Emma Hall, prosecuting, said: "The officers were of the opinion that the ladders were in such poor safety condition that they shouldn't have been available for use. It had the potential to cause a user to have a fall from height. The conditions that officers found were simply not safe and not acceptable."
The company had previously received several improvement orders, dating as far back as 2003, and even had its own set of safety regulations recognising ladders should be checked every six months.
Director Sam Pnasier pleaded guilty to all of the charges. Solicitor Reyaz Ali said his client accepted the ladders should not have been there and said the company has paid for further safety assessments.
