- Veterinary clinicsA state facility permit, controlled substances registration at both state and federal level, and a medical waste manifest — none of which a general business license covers.See the full permit list

What do these permits involve in Warren?
Certificate of Compliance
Warren calls this a Certificate of Compliance rather than a certificate of occupancy, but it functions identically — no space may be occupied, used, or changed in use until it is issued. A Knox Box for fire department access is required before it can be issued, and the application voids after 60 days for an occupied space or 180 days for a vacant one if not completed in time.
Commercial Building Permit
This fee schedule is dated 2014, and no newer version could be located on the city's own site — treat these figures as provisional and confirm directly with the Building Division before relying on them for a specific project.
Sign Permit
Anyone installing signs commercially must separately hold an Annual Sign Erector's License, a further $75 a year, expiring December 31, requiring its own $250,000/$500,000/$100,000 liability insurance.
