Unpermitted work is more common than most people realize — it shows up when homeowners sell, when insurers investigate claims, and when code enforcement comes knocking. After-the-fact (ATF) permits are how you make that work legal without tearing it down. MKC manages the full ATF process: assessing existing conditions, coordinating engineering documentation when required, applying for the permit, and handling any corrective work needed to pass inspection.

Services

What We Do

ATF Permit Applications

Filing the after-the-fact permit application with the county, submitting required documentation, and managing the permit desk relationship from submission through issuance.

Code Compliance Assessment

Inspecting the unpermitted work to determine whether it meets current code and what — if anything — needs to be corrected. We give you a straight answer before you're committed to a path.

Corrective Construction

When inspectors find that unpermitted work doesn't meet code, we make the corrections. Structural, electrical, plumbing, HVAC — MKC's trade team handles what needs to be fixed.

Engineering Documentation

For structural, load-bearing, or foundation-related unpermitted work, after-the-fact permits often require a signed and sealed engineering letter. Our Engineer of Record (EOR) produces those letters — no waiting on an outside firm.

Inspection Scheduling & Management

Scheduling and managing all required inspections — from the initial ATF inspection through final approval. We're on site for every inspection and we know what each inspector needs to close the permit.

Title Clearance Documentation

Providing the documentation needed to resolve open permit issues in real estate transactions — so closings can proceed without delays.

Our Work

Recent Projects

Unpermitted Room Addition — ATF Permit

Wesley Chapel

Homeowner discovered an unpermitted room addition when preparing to sell. MKC assessed the work, coordinated engineering documentation from our Engineer of Record (EOR), pulled the ATF permit, and managed inspections through final approval.

Garage Conversion — ATF Permit & Corrective Work

Tampa

Garage converted to living space without permits. MKC assessed existing conditions, identified code deficiencies, performed corrective work including HVAC and electrical upgrades, and obtained the after-the-fact permit through final inspection.

Pool Cage ATF Permit — Pre-Closing Resolution

New Port Richey

Pool enclosure added without a permit was flagged during a title search with closing in 30 days. MKC expedited the ATF permit process, coordinated inspection, and provided title clearance documentation in time for closing.

Common Questions

After-the-Fact Permits FAQs

An after-the-fact permit (ATF permit) is a building permit obtained for work that was already completed without going through the normal permit-and-inspection process. The county inspects the existing work, requires any corrections needed to meet current code, and then issues final approval — making the work legal and closing the permit on the property record.

Most types of unpermitted construction can be addressed through the ATF process — additions, garage conversions, pools, enclosures, electrical upgrades, plumbing changes, HVAC replacements, structural modifications, and more. The key variables are whether the work meets current code and what documentation the county requires.

The inspector will note what needs to be corrected before the permit can close. MKC handles that corrective work. In some cases the correction is straightforward. In others — especially structural work — it may require engineering documentation from our Engineer of Record (EOR). Either way, we give you a realistic picture of what it takes before we start.

It depends on the scope of the work, the county, and whether corrections are needed. Simple cases can close in two to four weeks. More complex projects — structural work, multi-trade issues, or significant corrections — can take longer. We'll give you a realistic timeline estimate upfront.
