The certificate of occupancy is the last thing standing between a finished space and an open business, and it is where schedules die. The work is done, the rent is running, and the building sits empty waiting for a signature.
Almost every CO delay traces back to one of five things, and every one of them is avoidable with sequencing rather than luck.
1. Accessibility
Pulling a permit can trigger accessibility obligations the building has been grandfathered out of for years. Restrooms are the usual failure: clearances, grab bar placement, lavatory height, door hardware, and approach space. An inspector will fail a restroom that has served the previous tenant perfectly well for a decade.
This is worth confirming before demo, not after, because the fix sometimes means moving a wall.
A build-out estimated at $50,000 or more also runs on a separate state track: it is registered with TDLR, submitted for Registered Accessibility Specialist review before the permit application is filed, and inspected within a year of completion. TDLR TABS registration and RAS inspections explains how that track meets the city's.
2. Fire and life safety
Change the layout and you change egress. Sprinkler head positions relate to the ceiling plan, exit signage relates to the path of travel, and alarm devices relate to the room count. If the fire marshal has a separate inspection and a separate queue, and in most DFW cities they do, that queue is on your critical path.
3. Health department, where it applies
Restaurants and medical spaces answer to a second authority with its own plan review and its own inspection. Those cycles do not run in parallel with the building department by default. Booking them late is one of the most common ways a restaurant opening slips by a month.
4. Inspections booked in the wrong order
Rough-in inspections have to pass before the work gets covered. Cover it first and you are opening walls back up. The sequence is not complicated, but it is unforgiving, and it is the contractor's job to hold it rather than yours.
5. Paperwork that nobody owns
- Signed and sealed drawings where the scope required them
- Contractor and subcontractor registrations current with that city
- Landlord authorisation letters for work in a leased space
- Fire alarm and sprinkler certifications from the installing contractor
- Final grease trap, hood, or medical gas certifications where applicable
Each of those is trivial on its own and each has held up a CO for a week because nobody was clearly responsible for producing it.

How long is a certificate of occupancy valid?
In Dallas, Fort Worth and Plano a certificate of occupancy has no fixed expiration date. It stays with the use and the occupant it was issued for, and it ends when one of those changes or the city revokes it. The details differ by city:
| City | Does the CO expire? | When a new CO is needed |
|---|---|---|
| Dallas | No fixed date. Under Chapter 52 it is void if the use does not start within 120 days, and the city revokes it once the use has been discontinued for six months or more. A temporary CO runs as long as the building official sets, with extensions. | A change of tenant, even when the use stays the same. A change of business name alone is handled as a record change. |
| Fort Worth | No expiration in the code. The building official can suspend or revoke one. | A change of ownership or tenant. If the use stays the same, it is a simpler application without a change-of-use permit. |
| Plano | No expiration stated. A temporary CO is limited to 45 days from issue. | A change of occupancy, business, business name or ownership. |
The Dallas six-month rule is worth knowing before you sign. In Dallas, a space whose use has been discontinued for six months or more has lost its CO, so the next tenant is not inheriting a certificate at all, whatever the listing says.
When does a new tenant need a new CO?
In the three largest cities we work in, yes. All three require a new certificate when the tenant or the owner changes, even if the space will be used exactly as before. The new occupant applies, the city inspects, and the certificate has to be issued before the business opens. That inspection looks at the space as it stands today, so a second-generation suite with an old restroom, missing exit signs or a blocked exit can fail it even when nothing was built. If you are taking over a space, walk it with that inspection in mind before you sign, and put the time it takes into the lease timeline.
How we sequence it
Design to permit approval averages three to four weeks across the markets we work in. We pre-file so review runs in parallel with finalising your scope rather than after it, book the fire and health inspections at the same time as the building inspections rather than in series, and hold the rough-in sequence so nothing gets covered early. The CO is the plan, not the hope.

Frequently Asked Questions
Common questions about this topic from DFW tenants, landlords, and business owners.
How long does a certificate of occupancy take in DFW?
The inspection itself is quick. What takes time is everything feeding it: design to permit approval averages three to four weeks, then the build, then building, fire, and where applicable health inspections. Booking those in parallel rather than in series is the single biggest schedule lever.
Why did my restroom fail inspection when it was fine before?
Because pulling a permit can trigger accessibility requirements the building was grandfathered out of. Clearances, grab bars, lavatory height, and door hardware are the usual failures. We check this before demo, since the fix occasionally means moving a wall.
Does the fire marshal inspect separately?
In most DFW cities, yes, with a separate queue. If your layout changed egress, sprinkler positions, or the room count, that inspection is on your critical path and needs booking early.
What paperwork holds up a CO most often?
Alarm and sprinkler certifications from the installing contractor, landlord authorisation letters, and current contractor registration with that specific city. Each is trivial and each has cost a week when nobody owned it.
How long is a certificate of occupancy good for?
In Dallas, Fort Worth and Plano there is no fixed expiration date. A CO stays with the use and the occupant it was issued for. In Dallas it is void if the use does not start within 120 days, and it is revoked once the use has been discontinued for six months or more. Plano limits a temporary CO to 45 days.
Does a new tenant need a new CO if the use is the same?
Yes, in Dallas, Fort Worth and Plano. All three require a new certificate when the tenant or owner changes. Fort Worth makes it a simpler application when the use is unchanged, and Dallas treats a business name change alone as a record change.
Who is responsible for scheduling inspections?
We are. Permits, plan review, and inspection coordination are part of the project, so it is our schedule problem rather than a checklist we hand you.
