Certificate of Occupancy vs Certificate of Use

Certificate of Occupancy

Issued by the building department. Certifies that a structure has been built or altered in accordance with the approved plans and applicable codes, and may be legally occupied for its intended use. Required for new construction, and typically for a change of occupancy classification. This is the document lenders, insurers and landlords ask for.

Certificate of Completion

Also from the building department. Issued where work is complete but the space is not intended for occupancy, or where the permitted work does not create occupiable space — a shell building, a site improvement, certain trade permits.

Certificate of Use

Issued by zoning or planning, not the building department. Certifies that your specific business activity is permitted at that specific address under the zoning code. Predominantly a Miami-Dade and South Florida requirement; elsewhere in Florida the equivalent step is usually zoning verification folded into the business tax receipt process.

A CU generally does not transfer with a business sale. New owner, new application. This catches people buying existing businesses with depressing regularity.

Business Tax Receipt

Issued by the local tax collector or city. The license to operate, historically called an occupational license. Frequently required at both city and county level — meaning two of them — and typically renewed annually.

How they chain together

Most jurisdictions will not issue the business tax receipt without the use approval, and will not issue the use approval without a passing inspection and often a valid CO. Run in sequence that chain can consume two months. The practical work is identifying which dependencies are genuine and which are habit, and running everything that can run in parallel.

The lease-signing checklist

1. Is my specific use permitted at this address under current zoning, by right or only by special exception?
2. Does the change from the previous use require a new Certificate of Occupancy?
3. Does the change of occupancy classification trigger upgrades to egress, accessibility, fire protection, restrooms or ventilation?
4. Does my parking calculation work at my intended occupant or seating count?
5. Are impact fees or utility connection fees triggered by the change of use?
6. Which of CO, CU and BTR does this jurisdiction actually require, and in what order?

Answering these before signing costs very little. Answering them afterwards has ended businesses before they opened.
