Commercial Permit Application Checklist
This checklist helps commercial property owners, businesses, and contractors identify the project-specific materials to gather before applying for a permit.
What this form is

Before applying, use the section for your project to identify items such as plans, contracts or scopes of work, licenses, surveys, and approvals. Requirements vary by project, and the checklist directs applicants to apply separately with the Fire Department for fire sprinkler systems and alarms.
