The municipal sign-off that says a building is legal to occupy.
A Certificate of Occupancy (CO) is the municipal document authorizing a newly-built, substantially renovated, or change-of-use property to be legally occupied. The CO is issued after final inspections confirm the building meets code, has all required systems operational, and is safe for the intended use. No tenant can legally move in until the CO is issued.
The CO process involves multiple inspections through construction. Foundation, framing, rough-in (electrical, plumbing, HVAC), insulation, and final inspections are typical milestones. Each requires the relevant trade work to be complete and accessible for inspection. The CO is issued only after the final inspection passes — typically the last step before occupancy.
Temporary CO (TCO) is sometimes issued when most of the work is complete but minor items remain. TCO allows occupancy for a defined period (typically 30–90 days) while the borrower completes punch-list items. TCO is common when developers need to start lease-up before every detail is finished. The full CO is issued when remaining items are completed and re-inspected.
CO timing affects financing directly. Construction loans typically require CO before converting to permanent debt or before the property can be refinanced into long-term debt. Lease-up loans and stabilization loans can't fund until CO is in hand. CO delays — even minor ones — can cascade into bigger financing problems if construction loan maturity is approaching.
For developers, managing CO process is critical. Stay ahead of inspection scheduling — most municipalities are 1–3 weeks out on inspector availability. Complete inspection-ready punch lists before the inspector arrives — failed inspections cost time. Communicate with the building department proactively. CO is fundamentally an administrative process that rewards process discipline; the projects that get COs fast are the ones whose teams understand the local building department.

The municipal document authorizing a newly-built or renovated property to be legally occupied. Issued after final inspections confirm the building meets code and is safe.
New construction (always), major renovations (work affecting structure, MEP, or use), and change-of-use conversions. Minor repairs typically don't require CO.
A short-term CO (typically 30–90 days) issued when most work is complete but minor items remain. Allows occupancy while the borrower finishes punch-list items.
After the final inspection passes, CO is typically issued within 1–5 business days. The variable timing is inspection scheduling — most municipalities are 1–3 weeks out from request.
Yes — permanent debt won't fund until CO is in hand. Plan construction timeline with adequate buffer between CO and loan maturity to allow refinance.
Matrix structures construction loans with refinance plans built around realistic CO timelines. No mismatch between construction completion and perm funding.
