A certificate of occupancy (CO) is one of the most important documents you’ll need before moving into a new building or opening a business. Issued by your local government, this document verifies that your project complies with building codes, zoning laws, and safety standards. Without it, property owners and developers risk delays, fines, or being unable to legally occupy their space.
What Is a Certificate of Occupancy?
A certificate of occupancy confirms that a building is safe and suitable for use. Local building departments issue the CO after final inspections are complete. Whether you’re developing a new multifamily property, finishing a tenant build-out, or adapting an older structure, the CO is the green light for occupancy.

Key Requirements for a CO
While requirements vary by jurisdiction, most municipalities require:
Completed building permit inspections (structural, electrical, plumbing, mechanical)
Compliance with zoning ordinances (use, density, setbacks, parking)
Fire and life safety approvals
Accessibility compliance
Each step requires coordination with inspectors and often multiple rounds of review. Partnering with architects who understand these requirements can streamline the process and reduce costly delays.
The Inspection Process
Final inspections typically include checks on:
Life safety: exits, sprinklers, alarms
Structural systems: foundations, framing, roofing
Mechanical systems: HVAC, plumbing, electrical
Accessibility: ADA and local code standards
After inspectors sign off, the CO is issued. If issues arise, you may be granted a temporary certificate of occupancy (TCO), allowing limited use until final corrections are made.
Why Developers Need to Plan Early
Waiting until the end of construction to think about a CO can cause serious delays. By addressing requirements during design and permitting, developers can avoid expensive rework. Architects familiar with permit drawings and code compliance can help you plan for inspections well before move-in day.
