Certificate of Occupancy & Closeout

Certificate of Occupancy (CO)

The CO is the building department's sign-off that the building is safe and legal to occupy. It's issued after final inspections of building, fire, accessibility, and site work pass. No CO, no move-in (and often no permanent financing). A temporary CO (TCO) may allow partial occupancy while punch items finish.

Closeout

Wrapping up the construction contract:

• Punch list — final corrections completed.
• Release of retainage — paid after punch list and final lien waivers.
• Final lien waivers from GC and subs.
• Warranties, O&M manuals, and as-builts delivered.
• Final payment and contract closeout.

Don't rush it

A disciplined closeout protects you: it confirms the work is complete, the liens are cleared, and you have the documentation you'll need for operations and any future warranty claims.

Going Deeper (Intermediate)

The Certificate of Occupancy (CO) — the building official's sign-off that a building is safe to occupy — is required before you can use, sell, or lease it. Closeout completes the punch list, paperwork, and final approvals.

Advanced / Pro-Level

The CO is the gate to revenue:

• The path: final inspections of all trades + fire + accessibility, sometimes a TCO (temporary CO) for partial occupancy.
• For horizontal work, subdivision improvement acceptance and bond release.
• Closeout docs: as-builts, O&M manuals, warranties, final lien releases.
• You can't close home sales or start leases without the CO, and it's the trigger to convert the construction loan to permanent (or pay it off with sale proceeds). A slow closeout withholds your revenue and your retainage — it's a financial event, not a formality.

Practice Challenge

Why can a developer's revenue and loan payoff stall even after the building looks "done"? (Answer: without the Certificate of Occupancy (final trade/fire/accessibility inspections passed) you can't legally sell or lease — so sales don't close and the construction loan can't be repaid/converted; the CO and a complete closeout are the gate to actually getting paid.)

In Practice

An owner can't get permanent financing because there's no Certificate of Occupancy yet. No CO, no move-in — and a rushed closeout leaves liens uncleared.

Common Mistakes to Avoid

• Rushing or skipping closeout
• Not securing the CO before occupancy
• Failing to collect final lien waivers

Takeaway: No Certificate of Occupancy, no move-in — and don't rush closeout; it clears your liens.
