Unpermitted additions, repairs, or structures can block property sales, trigger code enforcement liens, and create liability. Pineland Engineering provides the as-built drawings, structural calculations, and engineer letters Florida building departments require to close out unpermitted work.
After-the-fact permitting — sometimes called retroactive permitting or permit legalization — is the process of obtaining a building permit for work that was completed without one. In Florida, this is governed by Florida Statute 553 and enforced by county and municipal building departments. The process requires the property owner to submit construction documents that accurately reflect the as-built condition of the structure, along with any required engineering calculations. Pineland Engineering (AR102594 · PE 39202) handles this process for residential and commercial clients throughout Florida.
Why Unpermitted Work Becomes a Problem
Unpermitted construction in Florida creates several compounding problems. First, it appears on title searches — buyers, lenders, and title companies routinely flag open permits and unpermitted improvements, which can kill a closing. Second, Florida counties actively pursue code enforcement; a neighbor complaint or routine inspection can result in a Notice of Violation, a daily fine, and ultimately a lien on the property. Third, insurance companies may deny claims for damage to unpermitted structures. The longer unpermitted work sits unresolved, the more expensive it becomes to correct.
Florida Statute 553.79 requires a permit before construction begins. When work is done without one, the building department has authority to require demolition or require the owner to bring the work into compliance through the permit process — whichever the inspector determines is appropriate.
What the After-the-Fact Permit Process Requires
The after-the-fact permit process in Florida typically requires: (1) As-built drawings — floor plans, elevations, and details that show the structure exactly as it exists today, prepared and sealed by a Florida-licensed architect or engineer. (2) Structural calculations — if the work involves structural elements (additions, roof framing, elevated decks, load-bearing walls), a licensed structural engineer must provide calculations showing the existing work meets the Florida Building Code. (3) An engineer or architect letter — a signed and sealed professional opinion that the as-built work meets code or describing what remediation is required. (4) Permit application and fees — submitted to the county or municipal building department with jurisdiction.
Pineland Engineering provides all of the above. We perform a site visit, document the as-built conditions, and produce the complete permit package your building department requires.
Timeline and What to Expect
After-the-fact permitting in Florida typically takes 6–14 weeks from engagement to permit issuance, depending on the county, the complexity of the work, and whether any remediation is required. The process breaks down roughly as follows: site visit and documentation (1–2 weeks), drawing production and engineering (2–4 weeks), permit submission and plan review (3–8 weeks depending on county backlog). Some counties offer expedited review for an additional fee.
If the building department's plan reviewer identifies code deficiencies in the as-built work, a correction notice is issued. Pineland Engineering responds to correction notices as part of our standard scope — we do not charge separately for reasonable plan review responses.
What Happens If You Ignore It
Ignoring unpermitted work in Florida is not a viable strategy. Code enforcement departments in Lee, Collier, Charlotte, and Sarasota counties have become significantly more active since Hurricane Ian, as post-storm inspections revealed widespread unpermitted construction. Consequences of inaction include: daily fines that accrue until the violation is resolved, a recorded lien on the property that prevents sale or refinancing, mandatory demolition orders for structures that cannot be brought into compliance, and personal liability if an unpermitted structure causes injury.
Property owners who proactively address unpermitted work — before a code enforcement complaint is filed — typically have more options and lower costs than those who wait for enforcement action.
What Pineland Engineering Delivers
Pineland Engineering provides a complete after-the-fact permit package: site visit and field measurements, as-built architectural drawings (floor plans, elevations, sections, details), structural calculations where required, a signed and sealed engineer or architect letter, and permit application support. We hold Florida Architecture License AR102594 and Engineering License PE 39202, which allows us to seal both architectural and structural documents — most firms can only do one or the other.
We serve clients in Lee County, Collier County, Charlotte County, Sarasota County, and throughout Florida. Contact us at (239) 233-5133 or through our quote form for a free project assessment.
How much does after-the-fact permitting cost in Florida?
Costs vary by project scope. A simple unpermitted addition (under 500 sq ft, no structural concerns) typically runs $1,500–$3,500 for the engineering and drawings. Larger or more complex projects — elevated structures, commercial work, projects with code deficiencies — run higher. County permit fees are separate and calculated based on construction value. Use our PermitCalc FL tool for a fee estimate.
Can I sell my house with unpermitted work in Florida?
Technically yes, but practically it is very difficult. Lenders will often not finance a property with open code violations. Title companies flag unpermitted work. Many buyers walk away. The cleanest path to a successful sale is to resolve the unpermitted work before listing. Pineland Engineering can often complete the permit package within 6–10 weeks.
What if the unpermitted work doesn't meet current code?
This is common, especially with older additions. The building department will issue a correction notice listing what must be remediated. In some cases, the county allows a variance or alternative compliance path. Pineland Engineering identifies potential code issues before submission and advises on the most cost-effective remediation approach.
Do I need a structural engineer for an unpermitted addition?
If the addition involves any structural work — new roof framing, load-bearing walls, elevated decks, foundation work — yes, a licensed structural engineer must review and seal the structural drawings and calculations. Pineland Engineering's PE 39202 covers this.
