One of the most expensive mistakes contractors make in Central Florida is letting a permit expire before the work is finished. It happens more often than you would think. A job runs longer than expected. A change order delays the next inspection. Or the contractor simply loses track of time. When the permit expires, everything stops. Restarting is not as simple as picking up where you left off.
Every jurisdiction in Central Florida handles permit expirations differently. Time limits, renewal fees, and reinstatement processes vary from county to county. Knowing those differences can save you thousands of dollars and weeks of delays.
Here is what MLPS has learned from years of managing permits across Central Florida.
How permit expiration works
Most building permits in Florida have two relevant time periods: the initial validity period and the maximum overall period. The initial validity is how long you have to start construction after issuance. The maximum period is how long you have to complete the entire project once construction begins.
If those periods pass without the required progress, the permit expires. Expiration generally means the permit is no longer valid and construction must stop. To continue, apply for reinstatement or a new permit, pay additional fees, and resubmit plans if the code has changed since issuance.
Orange County
Orange County building permits have a six-month initial validity period. Construction must begin and pass the first inspection within six months of issuance. After that, the permit remains active as long as inspections continue at reasonable intervals — typically one inspection every 180 days. The overall permit life is two years, with extensions available for active projects that need more time.
Renewal fees apply for extensions, and plan review may need updating if the building code has changed. MLPS handles these renewals through our Orange County permit services.
Seminole County
Seminole County also uses a six-month activation requirement. Construction must start within six months of permit issuance. For active construction, the permit stays valid as long as there is an approved inspection at least once every six months. If six months pass without an inspection, the permit is considered abandoned and expires.
Seminole County allows administrative extensions, but the timelines are strict. The extension must be requested before the permit expires, not after. A lapsed permit requires a new application, plan review, and full fees.

Osceola County
Osceola County permits require that construction start within six months and that at least one approved inspection occurs every 180 days. The total permit life is two years, with the possibility of one-year extensions. Osceola is generally more flexible than some other counties when it comes to extending active permits, but the extension request must be submitted before expiration.
Fees for extensions vary based on the permit value and scope of remaining work. MLPS recommends tracking your permit from issuance — set a calendar reminder at five months, not six, so you have time to act before the deadline.

Lake County
Lake County follows a similar six-month activation rule but has stricter reinspection requirements. If an inspection fails, the contractor has limited time to correct it and request a re-inspection before the permit risks being marked inactive. The overall permit period is two years.
For projects in Lake County, MLPS recommends scheduling inspections proactively rather than reactively. If you know an inspection is coming up, schedule it before the deadline even if the work is not 100% done — you can request a partial inspection to document progress.
See our Lake County permit services page for more.
Polk County
Polk County permits expire if construction does not begin within six months or if there is no approved inspection within 180 days of the last inspection. The maximum permit term is two years. Polk County also charges a reinstatement fee for expired permits, typically higher than an extension fee.
We track permit timelines for Polk County clients and send reminders before expiration deadlines. Visit our Polk County permit services page for details on their specific requirements.
The cost of letting a permit expire
An expired permit is more than an administrative inconvenience. Here is what it typically costs:
- Reinstatement or new permit fee: varies by county but can be 50% to 100% of the original permit fee.
- New plan review: if the code has been updated, your plans may need revision.
- Construction delays: you cannot legally continue work while the permit is inactive. Crews may need to be reassigned.
- Inspection re-validation: some counties require inspections that were already passed to be re-verified.
A permit expiring three months before completion can end up costing more than the original permit itself. And that does not count the lost time.
What every contractor should track
MLPS recommends keeping a permit calendar that tracks three dates for every active permit:
- Issuance date. Your start clock starts ticking from this day. Count six months forward for your first inspection deadline.
- Last inspection date. You need another approved inspection within 180 days (or whatever your jurisdiction requires) to keep it active.
- Permit expiration date. The maximum life of the permit. If the project is not closed out by this date, the permit expires regardless of inspection activity.
Most online permit portals show these dates. Check them monthly for every open permit. If you manage multiple projects across multiple counties, this is even more important — MLPS has seen contractors lose permits because they were focused on one job and forgot about another.
