Long wait times to submit building-permit applications and a disorganized filing system are delaying development across Denver, an audit has found. People start lining up hours before the Department of Community Planning and Development opens to hand in plans for review, according to Denver Auditor Timothy O’Brien. O’Brien said the agency should take steps to improve its intake practices to dramatically improve efficiency. “Imbalances in staff training and long wait times are holding up the business of growing and developing the City of Denver,” O’Brien said in a written statement Thursday. The department says that improvements are already either completed or underway in response to the auditor’s report, like better use of digital-submission systems, which have begun to reduce waits for those trying to file plans.
