If your building permit has expired, stop work and phone the building department today. You need an answer to one question: will they extend or reinstate this permit, or do you have to apply from scratch? Reinstatement is nearly always cheaper, but departments only offer it for a while. After that call, gather your inspection records, book whatever inspections you still owe, and push the permit through to formal closure.
As a rule, nobody sends a warning letter. The permit just stops being valid, and you find out when an inspector turns up, when a buyer's permit search flags it, or when the lender won't fund the next draw. Below: how long permits last in a few states, why they lapse, what it costs you, and how to fix it.
What an expired building permit means
Every permit runs on a clock. Section 105.5 of the International Building Code, which most US cities and counties adopt with their own tweaks, says a permit goes invalid if work hasn't started 180 days after issue, or if work stops for 180 days once it has. From then on the permit authorizes nothing. Hang one sheet of drywall the next morning and you're legally working without a permit.
Open permit versus expired permit
People mix these two up. An open permit is a job that started but never got its final inspection, so it sits on the city's record as unfinished. An expired permit simply ran out of time. A permit can be both. Picture a bathroom remodel from years ago that nobody signed off: open on paper, expired for ages, and discovered the week you list the house.
How long is a building permit valid?
Plan on 180 days unless your local code says otherwise, and plenty do. Under the model code, each approved inspection counts as progress and restarts the clock. Phoning to request one doesn't. The inspector has to come out and pass the work.
We checked three states against the statute or code text itself:
| Where | When the permit expires | Source |
|---|---|---|
| Florida (single-family dwellings) | 1 year after issue, or when the next edition of the Florida Building Code takes effect, whichever is later. The local government can extend it. | Fla. Stat. 553.79 |
| North Carolina | 6 months after issue if work hasn't started (a local ordinance can set less), or immediately once work has stopped for 12 months | N.C. Gen. Stat. 160D-1111 |
| California | The 2022 California Building Code (new Section 105.5.1) moved expiry from 180 days to 12 months for starting work | California Building Standards Commission |
| Most other places | The model code baseline of 180 days, as amended locally | Your local building code |
Sources: Florida Statutes 553.79, N.C. Gen. Stat. 160D-1111 and the California Building Standards Commission summary of the 2022 code changes. Cities and counties amend these all the time, so treat the table as a starting point and confirm the number with your own building department.
Florida adds a courtesy. The same statute lets the local government email or post a notice to the owner and contractor at least 30 days before a permit expires. It's optional, so don't rely on it.
Why building permits expire
Almost nobody lets a permit go on purpose. A project stalls or changes hands, and the date slides by because no single person was watching it.
The next inspection never gets booked
Say the framing on a kitchen extension is finished in April. The site lead assumes the office booked the framing inspection; the office assumes the site lead did. By October nobody has, and the permit's gone. Lovely framing, though.
The project pauses for longer than you planned
The loan draw comes in late. The client decides she wants the bigger window after all, and the roofer can't come back until March. Three months turns into seven. Unless someone has that date under active tracking, the pause runs straight past expiry.
The contractor walks off the job
When a contractor leaves mid-job, the permit file usually goes too, in a truck cab or an email inbox you can't get into. The replacement crew has no idea where things stand. And the owner doesn't learn the renewal deadline has passed until somebody asks to see the permit card.
Dates live in five spreadsheets and nobody owns them
With six jobs running, permit dates end up in a site diary, two spreadsheets and the estimator's Outlook. Nobody has a single view of what's due and when. We see this more than any other cause.
What happens when a building permit expires
An expired permit is a compliance risk with a price tag. Work done after the lapse counts as work without a permit, and the penalty is often a multiple of the permit fee.
New York City shows how that adds up. Under 1 RCNY 102-04, the civil penalty for a one- or two-family home is six times the current permit fee (at least $600, at most $10,000). For any other building it's 21 times the fee, between $6,000 and $15,000.
The fine is often the smaller problem. The department can issue a stop-work order, so your crew stands around while the schedule slips. If the inspector can't see what's behind finished drywall, you may have to cut it open, and anything that isn't to code comes out.
Then there's the end of the job. No valid, closed permit means no certificate of occupancy, so nobody can legally move in or open the doors. Insurers may push back on a claim that involves unpermitted work. Lenders often won't close while a permit issue is open.
Five steps to take when your permit has expired
Work through these in order. Going straight to a fresh application usually costs more than it should.
1. Confirm the status with the building department
Ask whether the permit is expired, open or closed, and on what date it actually lapsed. Online portals lag, so phone or go to the counter. Note the name of whoever you spoke to.
2. Gather your inspection records
Pull together the original permit, every inspection result with its date, your contractor's paperwork and any emails with the department. Reinstatement turns on what you can prove was already approved. Missing the rough electrical sign-off? Expect a re-inspection, and if that wiring is now behind drywall, someone's opening the wall.
3. Ask for an extension or reinstatement before you reapply
Lots of departments will extend or reinstate a permit that lapsed recently. The model code lets the building official grant extensions in writing, usually on a written request with a reason (a supplier delay, a lender hold-up). Ask before the date if you possibly can.
4. Book the outstanding inspections
Once it's reinstated, book the remaining inspections in the right order. The department will tell you which ones you still owe.
5. Pay the fees and close the permit
Pay the reinstatement fee, pass the final, and get written confirmation that the permit is closed. That's the document a buyer's title and permit search goes looking for.
Extending a permit versus renewing an expired one
An extension keeps a live permit alive. Reinstatement revives a dead one. Extensions are far easier, which is the best reason to watch the date.
What departments usually ask for
Expect them to want a written request that quotes the permit number and says why you need more time, along with the original permit, your inspection history and the scope. Timing matters. Most want the request before expiry, or soon after if there's a grace period, and some also want proof that work had started before the permit lapsed.
Fees and timing
Reinstatement fees come from each department's published fee schedule and are often worked out from the original permit fee, not charged as a flat amount. Ask for the exact line item, and ask whether re-inspections are billed separately. Processing can take days or weeks, depending on the department's backlog and whether the code has changed since your permit was issued. Our renewal date calculator helps you work back from the expiry date to the day you should file.
How to close an open or expired permit
Closing a permit means passing the final inspection and getting formal closure from the department. It matters most when you sell, because open permits turn up in title and permit searches.
Florida has two helpful rules in section 553.79. If an expired permit's work is substantially complete, the local agency can let you close it without pulling a new permit. And a local agency may close a permit 6 years after issue, even without a final inspection, if it finds no apparent safety hazard.
If the original work doesn't meet the code that now applies, you may have to fix it before closure. Ask the department what it will accept. Some will agree a practical way through.
How an expired permit affects buying or selling a property
Open and expired permits regularly delay sales. Here's who carries what.
If you're selling
Expect to close open permits before completion or to give the buyer a credit to cover the cost. Permit searches during due diligence usually find them, so it's better to raise the issue yourself.
If you're buying
Code enforcement can follow the property, not the previous owner, so you may inherit the problem. Run a permit search before you commit. In Florida, the statute stops a local agency from fining or refusing permits to an arm's-length buyer just because a previous owner's permit was never closed. That protection isn't universal.
If you're the agent
You may have duties to disclose known permit issues. Recommending a permit search early protects your client and the deal.
How to stop your next permit expiring
Watching a date costs far less than reinstating a permit. Four habits do most of the work, and they're the permit version of our expiry management practices.
Keep every permit in one list
Keep one register for every active permit on every job: permit number, issue date, date of the last approved inspection, and the date it lapses if nothing else happens. A shared sheet copes with three jobs. At fifteen it starts to crack.
Give each permit a named owner
Name a person, not a team. On most jobs that's the project manager, sometimes the site super. It ends the "I thought you had it" conversation.
Remind early, and more than once
One email gets lost on a job site. Send automated reminders through more than one channel, starting 90 days out so there's time to get an inspector booked, and again at seven days as a last call. Reset them after every passed inspection, since that resets the permit's clock too.
Keep a record of every inspection and request
Log each inspection, extension request and renewal with its date. When the department or a compliance audit wants proof, you can demonstrate compliance in a couple of minutes instead of rebuilding it from texts and memory.
Track permit dates with ExpiryEdge
ExpiryEdge holds each permit with its expiry date and a named owner. It reminds that person before the date by email, SMS, WhatsApp, Slack or Microsoft Teams, and if the date passes with nothing done, it tells their manager.
When a permit gets extended or closed, upload the paperwork to the record. Every reminder and action lands in an audit trail you can export. The trial runs 14 days and doesn't need a credit card.
Frequently asked questions about building permit expiration
How long is a building permit good for in NC?
Under N.C. Gen. Stat. 160D-1111, a permit expires six months after it's issued if work hasn't started, and a local ordinance can set a shorter period. Once work has started, the permit expires immediately if the work stops for 12 months. Check your county or city ordinance for anything stricter before you plan a pause.
How long is a building permit good for in TN?
Tennessee doesn't have one period that applies everywhere. Cities and counties that enforce codes set their own terms, and many follow the International Building Code's 180-day model rule with local amendments. Call the department that issued your permit and ask for the expiry date in writing. It's the only number you can rely on.
How long is a building permit good for in Oklahoma?
It depends on the city or county that issued it. Many Oklahoma jurisdictions use the International Building Code's model rule: invalid if work doesn't start within 180 days, or stops for 180 days. Local amendments are common, though. Ask your building department for the exact expiry date, and whether it grants extensions on a written request.
Can an expired building permit be reinstated or do I need a new one?
Often you can reinstate it. That's most likely if it expired recently and work was already under way when it lapsed, though each department sets its own window, so ask straight away. Wait too long and you'll usually need a new application under the current code. Expect updated plans and new fees.
Who is responsible for renewing a building permit, the homeowner or the contractor?
The contractor usually handles it during an active job. The owner carries the risk, though, because enforcement follows the property, so an open or expired permit becomes your problem when you sell or refinance. If your contractor walks off, don't wait. Call the department yourself that week and ask for the permit's status.
