Quick Answer
After-the-fact permitting in Florida is the process of obtaining a building permit for construction that was completed without one. Florida building departments accept retroactive permit applications, but they require the same documentation as a standard permit — as-built drawings sealed by a licensed Florida engineer or architect, code compliance analysis, and in most cases, a physical inspection of accessible structural elements. Engineering and architectural fees typically run $3,000–$10,000 for a residential project; building department fees are the same as a standard permit, though some jurisdictions add a 25–100% penalty surcharge for unpermitted work. Timeline is typically 4–12 weeks. If the work does not meet current Florida Building Code, the building department will require remediation before issuing the permit.

What Is After-the-Fact Permitting?
After-the-fact permitting (sometimes called retroactive permitting or permit after construction) is the process of obtaining a building permit for work that was already completed without one. Florida building departments have processes for this, but they vary by county and municipality. In Lee County, Collier County, and Charlotte County, after-the-fact permits typically require the same documentation as a standard permit — plus additional steps to verify that the existing work meets current code.
Why It Matters
Unpermitted work creates real problems. When you sell a property in Florida, you are required to disclose known unpermitted work. Buyers' lenders may refuse to finance a property with unpermitted structures. Homeowner's insurance may deny claims for damage to unpermitted additions. And if the county discovers unpermitted work — through a neighbor complaint, a routine inspection, or a permit application for other work — you may receive a code enforcement notice requiring you to either permit the work or demolish it.
The After-the-Fact Permitting Process
The process varies by jurisdiction, but generally follows these steps:
- Hire a licensed architect and/or engineer to prepare as-built drawings of the existing work
- The engineer or architect reviews the work against current Florida Building Code requirements
- If the work meets code, sealed drawings are prepared and submitted to the building department
- The building department reviews the drawings and may require inspections of accessible structural elements
- If the work does not meet code, you have options: remediate the deficiencies, or in some cases, obtain a variance
- Once approved, the permit is issued and closed, and the work is officially on record
What Happens When the Work Doesn't Meet Code?
This is the hard part. If the unpermitted work doesn't meet current Florida Building Code — for example, if an addition was built without proper hurricane straps, or a structure in a flood zone was built below the required elevation — the building department may require you to bring it into compliance before they'll issue the permit. In some cases, this means opening walls, adding structural connections, or elevating the structure. In extreme cases, it may mean demolition.
The good news is that experienced engineers can often find code-compliant solutions that don't require tearing everything down. Pineland Engineering has worked on numerous after-the-fact permit projects throughout Lee County, Collier County, and Charlotte County. We prepare the as-built drawings, perform the code analysis, and work with the building department to find the most practical path to compliance.
Costs and Timeline
After-the-fact permitting typically costs more than a standard permit because of the additional documentation and analysis required. Engineering and architectural fees for a residential after-the-fact permit typically range from $3,000 to $10,000 depending on the scope and complexity of the work. Building department fees are typically the same as a standard permit, though some jurisdictions charge a penalty fee for unpermitted work. Timeline is typically 4–12 weeks from engagement to permit issuance, depending on the building department's review backlog.
Special Considerations for Coastal Properties
After-the-fact permitting is particularly complex for coastal properties in flood zones. If unpermitted work was done in a Zone AE or Zone VE area, the building department will scrutinize flood zone compliance closely. Structures built below the Base Flood Elevation, or with enclosures that don't meet breakaway wall requirements, may require significant remediation. If you're dealing with an unpermitted structure on a coastal property in Southwest Florida, it's important to work with an engineer who understands FEMA flood zone requirements — not just the general building code.
After-the-Fact Permits and Property Sales
If you're in the middle of a real estate transaction and unpermitted work has been discovered, the timeline can be tight. Some building departments offer expedited review for after-the-fact permits when a property sale is contingent on permit resolution. Pineland Engineering can often prepare the necessary documentation quickly to keep a transaction on track. We've worked with buyers, sellers, and real estate attorneys throughout Southwest Florida to resolve permit issues before closing.
Frequently Asked Questions
How much does after-the-fact permitting cost in Florida?
Engineering and architectural fees for a residential after-the-fact permit typically range from $3,000 to $10,000 depending on the scope and complexity. Building department fees are generally the same as a standard permit, though some jurisdictions add a penalty fee for unpermitted work.
Can you get an after-the-fact permit for any type of work?
Most types of work can be permitted after the fact if they meet current Florida Building Code. Common examples include room additions, accessory structures, electrical upgrades, and plumbing modifications. Work that cannot be brought into compliance (e.g., a structure built below the required flood elevation that cannot be elevated) may need to be removed.
What if the unpermitted work doesn't meet current code?
The building department will require you to bring the work into compliance before issuing the permit. This may involve opening walls, adding structural connections, or in extreme cases, demolition. An experienced engineer can often find practical solutions that avoid the most costly remediation.
How long does after-the-fact permitting take in Florida?
Typically 4 to 12 weeks from initial engagement to permit issuance, depending on the building department's review backlog and the complexity of the work. Some jurisdictions offer expedited review when a property sale is contingent on permit resolution.
Do I need an engineer for after-the-fact permitting?
In most cases, yes. Florida building departments require engineered drawings and calculations for structural work, additions, and anything in a flood zone. A licensed Florida PE (Professional Engineer) must sign and seal the permit documents.
