Some cities agree to reduce permit fees when sprinklers are installed. Scottsdale, Arizona dropped the fire-related permit fees altogether for sprinklered buildings. The logic is that the department will absorb the cost of plan reviewers and inspectors as its contribution to lowering the net cost of sprinklers. In many cases, the increased workload will be very little for plan reviewers, who are already on hand to review the structural plans. The plumbing inspectors can be trained to handle sprinkler inspections, and fire firefighters can also be trained to do this work.
