Temporary certificate of occupancy vs. final CO in North Carolina: what a TCO allows, how long it lasts and who uses them

A temporary certificate of occupancy, or TCO, lets people use all or part of a building before the final certificate is issued, for a stated period, when the inspector finds it can be occupied safely. North Carolina's law allows it in one sentence (G.S. 160D-1116(b)); each inspections office decides how to grant it, for how long and for what fee. In practice TCOs are a tool for apartment buildings and commercial spaces, not houses: in Durham, half of the apartment buildings permitted since 2021 still show a conditional CO as their latest step, against one house in a thousand. This guide covers the difference between a TCO and a final CO, what offices require, how long a TCO lasts, and what happens when it runs out.

Temporary vs. final certificate of occupancy

What offices require for a TCO

The statute leaves the details to each office. Two that publish theirs:

• Mecklenburg County: every building, electrical, mechanical and plumbing permit on the project, and every agency hold, must be finaled, released or approved for the TCO. The fee is $90 per open permit for a first TCO and $55 per open permit to renew, plus $55 for each renewal inspection, and only general contractors with an account can get one. A placard showing the TCO's conditions and expiration date must stay posted until the CO is issued. A contractor with a TCO expired more than 30 days can't get another until it's renewed or completed.
• Guilford County: sprinkler, smoke detection and fire alarm systems, where the building has them, must be working and tested and verified by the fire inspector; the general contractor is responsible for any re-inspection fees; and an application that hasn't produced a TCO within 90 days is voided.
• Durham City-County: in its records a temporary certificate appears as its own status, Cond. CO Issued (a conditional CO), with the date it was signed off.

One limit applies everywhere. An office can't withhold a building permit or certificate of occupancy to force work on a different property unless there's a public safety issue, and landscaping on house lots and in subdivision common areas, and subdivision street lights, don't count as one; the developer files an affidavit saying when that work will be finished instead (G.S. 160D-1110(h)). That's one reason houses rarely need a TCO.

Who uses TCOs: what Durham's records show

Durham records the date each certificate was signed off and whether it was a final or a conditional CO, so its permits show which buildings end up waiting on a temporary certificate. Of the 23,814 permits issued since 2021 that have reached either, 368 (1.5%) still show a conditional CO as their latest step. Nearly all of them are apartments and commercial buildings.

That lines up with how those buildings are built: an apartment complex is often finished and leased in stages, and a commercial tenant may want to open its space while work elsewhere in the building goes on. A house is usually finished all at once.

When a temporary certificate becomes permanent in practice

A TCO is supposed to end in a final certificate, but the records show many that haven't. In Durham, 267 of the 368 conditional COs, 73%, were signed off more than a year ago and still have no final. In Mecklenburg County, 176 permits show TCO Issued today: 145 are commercial upfits, additions and repairs, six are apartment buildings and none are houses. The typical permit among them was issued about five months ago, and 35 were issued more than a year ago. For a buyer, tenant or lender, a TCO that has been renewed for a year is worth asking about: something on the project still hasn't passed its final inspection.

For buyers, owners and contractors

• Buyers and tenants: check whether the building has a final or a temporary certificate, and if it's temporary, when it expires and what's left. The permit record at the office, or Permit Search, shows the status.
• Owners: occupying without either certificate is a misdemeanor, and so is letting a tenant move in early; temporary power from the utility isn't a substitute.
• Contractors: a TCO needs every trade on the project finaled or signed off for it, the life-safety systems working, and a renewal before it lapses. In Mecklenburg an expired one blocks your next.

How the numbers were counted

Durham: permits in TarSignal's copy of the City-County records issued from January 1, 2021, whose status is CO Issued or Cond. CO Issued and which carry a certificate sign-off date, grouped by the building type Durham records. A status is the latest step, so a building that had a conditional CO and later got its final counts as final; the share at a conditional CO is the buildings still waiting. Mecklenburg: permits whose status was TCO Issued on October 24, 2026, by the county's building use code and issue date. Rules are as published in G.S. 160D-1110 and 160D-1116, on Mecklenburg County's TCO page and on Guilford County's TCO application in October 2026; other offices set their own terms.
