The goal of the Aurora Building Division’s Life Safety Staff is to assist the developer/builder with assembling a comprehensive set of plans that will result in their project moving smoothly through the building review process in the least amount of time (specific time tables are shown on the last sheet of this checklist). The material contained within this checklist will aid in both the predictability and timeliness of the plan review process and eventual installation of your project. This checklist contains the minimum standard information required for a project submitted for the plan review of Kitchen Hood Fire Suppression systems. Plans sets submitted without the minimum information listed below cannot be accepted for review.
Before the installation of any hood suppression system may commence, a currently licensed D-7 contractor with the City of Aurora must be issued the appropriate permit for all work performed. Licensing information is available from the Aurora Building Division by calling 303-739-7420. Please ask for a licensing representative.
Pre-Submittal Consultations with our Life Safety staff are available upon request.
