A report by RSH found that the council failed to meet the Safety and Quality Standard and Transparency, Influence and Accountability Standard, giving it a C3 grading.
It showed the council commissioned stock condition surveys for 86% of its homes but it only held partial data so it could not fully analyse the results.
It reported that 99.54% of homes met the Decent Homes Standard, though this had not been verified against the survey information.
The council also identified 800 homes with Electrical Installation Condition Reports over five years old, and 600 homes without a smoke alarm.
Edwards said: “The regulator’s findings set a clear benchmark for the standards our tenants should expect, and work is already under way to ensure those changes make a tangible difference.”
