Working without a permit when a permit is required can result in fines, and it can cause real problems when you sell your home. More importantly, you lose the assurance that the construction work is built to code and meets the minimum safety requirements that the permit process is designed to verify.
For some homeowners, the temptation to skip the permit is short-term — a small project, a contractor who says "you don't really need one for this," a desire to avoid the application fee. For others, the work was done years before they bought the property and the issue only surfaces during a sale, refinance, four-point inspection, or insurance renewal. Either way, the consequences eventually arrive — and the longer they sit, the harder they are to resolve.
This article walks through the three reasons unpermitted work is a problem, the after-the-fact permit pathway that legalizes existing work, and the "double fee" rule that applies once a Notice of Violation has been issued.
The three reasons unpermitted work matters
1. Fines and code-enforcement exposure
When a code-enforcement officer in Miami-Dade or Broward identifies unpermitted construction — through a neighbor complaint, a routine inspection, a four-point report, or by spotting it from the street — the standard first step is a Notice of Violation. Daily fines typically start accruing at $250 per day after a cure period expires and can escalate to $500 per day for repeat or serious violations. Some municipalities, particularly Coral Gables and Miami Beach, apply higher tiers. A six-month-old unresolved violation can easily accrue $30,000 to $90,000 in fines before mitigation. Our code-enforcement liens guide walks through how those assessments compound and how mitigation reduces them.
2. Resale and refinance friction
Title companies pull permit history during their search. Lenders order four-point inspections on homes over 25 years old. Buyers' inspectors check for visible signs of unpermitted additions. When unpermitted work surfaces during any of these processes, it can stall the transaction or kill it outright. Most lenders won't fund against a property with an active code-enforcement file. Many title insurers won't issue clean title with unresolved permit issues. Some buyers walk away rather than inherit the problem. Resolving unpermitted work before listing — through the after-the-fact pathway described below — is almost always faster and cheaper than trying to fix it during a 30-day closing window.
3. The safety and code-compliance assurance you lose
This is the reason the permit process exists in the first place. When a permit is pulled and the work is inspected, you get verified assurance that the structure is built to the Florida Building Code — including hurricane-load requirements specific to Miami-Dade and Broward's High-Velocity Hurricane Zone (HVHZ), product approval (NOA) documentation for exterior materials, proper fastening, electrical compliance, and so on. Work done without a permit may be perfectly fine, or it may have hidden deficiencies that wouldn't survive a storm or an insurance claim. You don't know until it's tested — and "tested" usually means a hurricane, a water intrusion event, or a structural failure. The permit process is designed so you don't have to find out the hard way.
The after-the-fact permit pathway — same process, with one extra step
Permits may still be issued, and inspections can still be performed for existing work that was done without a permit. The process is largely the same as it is for newly performed work — but any work that was done without a permit may need to first be uncovered so an inspector can verify it was done correctly and according to code.
"Uncovered" here is literal. A wall opening that was framed, insulated, drywalled, and painted years ago can't be inspected without removing the drywall (or at least cutting inspection holes) so the inspector can see the framing, the electrical connections, the insulation, and any structural fasteners. A deck that was screened and finished needs the underside accessible so the inspector can verify the joists, ledger attachment, and footings. A pergola attached to the house may need the connection to the wall opened up to verify proper flashing and fastening.
Our specialists and the inspectors we coordinate with will work with you to determine exactly how much work needs to be uncovered and/or corrected — and we scope it ahead of time so you know what to expect before the inspector arrives. In many cases, only targeted inspection openings are required, not a full demolition. In others, the work may need to be partially redone because a critical detail (hurricane straps, proper fastener spacing, structural connection points) wasn't installed correctly the first time. Either way, the goal is to bring the existing structure into documented code compliance with the minimum disturbance to your finished space.
What the after-the-fact application looks like
Procedurally, an after-the-fact permit follows the same steps as a new permit:
- As-built drawings documenting the existing structure as it stands today
- Engineering analysis where the structure requires it (most pergolas, terraces, additions, and enclosed spaces in HVHZ)
- Product approval (NOA) documentation for any exterior products that need it
- Permit application filed with the appropriate municipality, marked as after-the-fact
- Plan review by the building department against current code
- Field inspection of the existing work — including any uncovering required
- Corrections if the inspector identifies deficiencies
- Final inspection once all corrections are addressed
- Permit closure against the property record
The total timeline is usually 8–16 weeks for residential after-the-fact cases, depending on the complexity of the work and how cooperative the municipality's review queue is. The relevant practice page is our After-the-Fact Permits service, which goes into more detail on the categories of work we routinely legalize.
The double fee rule — what happens once an NOV is issued
If a Notice of Violation has been issued for work done without a permit, the after-the-fact permit is subject to violation penalties known as a "double fee." The permit applicant is required to pay an additional fee of 100% of the usual permit fees in addition to the required permit fee — effectively doubling the cost of the permit itself.
To put concrete numbers on it: if the standard permit fee for your project would have been $850, an after-the-fact permit pulled after an NOV has been issued will cost $1,700 for the permit alone (plus engineering, drawings, and any other costs that always apply). The fee differential is not a punishment for the contractor — it's a fee imposed by the municipality on the property owner as the legal applicant.
There are three things worth knowing about the double fee in practice:
- It applies after the NOV, not before. If you voluntarily disclose unpermitted work and file an after-the-fact application before a code-enforcement officer cites you, the permit is charged at the standard rate. This is one of the strongest arguments for resolving unpermitted work proactively rather than waiting until the city catches it.
- It applies in addition to any code-enforcement assessment. The double fee is municipal permit fee revenue. The fines accruing from the NOV are a separate code-enforcement matter. Both have to be addressed.
- Mitigation can reduce the code-enforcement assessment, but not the double fee. If you successfully mitigate a $40,000 code-enforcement assessment down to $4,000, you've made meaningful financial progress — but the doubled permit fee still applies on the underlying after-the-fact permit itself.
This is why we routinely encourage homeowners who know they have unpermitted work on their property to file before an NOV arrives. The permit cost is half, the code-enforcement assessment doesn't exist yet, and the path to closed-out property record is significantly cleaner.
The voluntary disclosure advantage
When you initiate the after-the-fact permit yourself — before any city officer has cited you — you control the timeline, the scope, the contractor, and the disclosure narrative. When an NOV initiates the process, the municipality is in control: the cure period clock is already running, the daily fines are already accruing, and the resolution scope is dictated by whoever wrote the citation.
The financial difference is meaningful. The narrative difference is even bigger. Voluntary disclosure presents to title companies, future buyers, and insurance underwriters as "we found an old issue and resolved it correctly." NOV-triggered resolution presents as "we got caught and had to fix it." Both end in the same closed-out permit on the property record, but the first one tells a better story for resale years later.
How to find out if you have unpermitted work on your property
Most homeowners are not actually sure whether the prior owner pulled permits for everything that's on the property. The deck, the screen enclosure, the pergola, the converted garage, the enclosed Florida room, the second-floor addition — any of these may or may not be in the permit record. The only way to know is to pull the record.
Our free MyHausFax™ Snapshot does exactly that. We pull every permit ever issued on your property from Miami-Dade or Broward records, compare it against the visible structures and improvements on the property (using property appraiser data and aerial imagery), and identify any structures that appear to lack a corresponding permit. Within one business day you'll have a written report telling you your HauScore™ and a clear list of any apparent permit gaps. If gaps exist, you can decide what to do next — and you'll be making the decision with data instead of guesswork.
If you already have an NOV
The path forward is unchanged in its mechanics but tighter on timeline. The cure period — typically 30 to 60 days — is the window in which you can resolve the violation without daily fines beginning to accrue. The first call should be to pull the property record, the second should be to scope the after-the-fact permit, and the third should be to file. Each day inside the cure period is a day saved from the fine clock.
Our Permit Violations service covers this end-to-end — from the initial NOV response, through scoping the resolution, filing the after-the-fact permit (with the double fee built into the budget), coordinating any required engineering and drawings, attending the inspection, and closing the file against the property record. Most NOV-triggered cases close in 8–14 weeks once we have the scope mapped.
