Quick Answer
Short answer: a Charlotte County remodel needs a construction permit application, plans that show existing and proposed work, complete product approval numbers, energy forms where they apply, and either an elevation certificate showing the building is above the flood hazard elevation or the county's 50 Percent Review form.
Charlotte County's Building Construction Division, inside the Community Development Department, handles permits for Port Charlotte, the Charlotte County side of Englewood and the rest of unincorporated Charlotte County (the City of Punta Gorda runs its own building department). Its remodel and addition checklists are unusually specific about drawings, product approvals and flood documents. The details below come straight from those checklists.

What documents does a Charlotte County remodel permit need?
The county's residential remodel page lists: the Application for Construction Permit; a recorded Notice of Commencement for any improvement with a direct contract price over $5,000, submitted before the first inspection; drawings that clearly show existing conditions and the proposed work; product specifications; energy calculations if applicable; the 50 Percent Improvement or Damage Review Application where the property is in a flood hazard zone; a subcontractor worksheet if electrical, mechanical, plumbing or roofing work is subcontracted; and owner-builder disclosure forms if the owner is the builder.
In person, the county wants two original sets of plans. Online, one set, digitally signed with third-party verification.
How should product approval numbers be listed?
Charlotte County asks for the complete product approval number for windows, doors, roof coverings, siding and soffits, including the number after the decimal point, not the revision "R" number.
Its example: 251 is the general number with several configurations, and the complete number would be 251.1. Florida numbers are searchable at floridabuilding.org and Miami-Dade NOA numbers at miamidade.gov. Getting this right on the first submittal avoids one of the most common correction comments.
What reviews does a Charlotte County addition go through?
The residential addition page lists the review stations: intake and sufficiency, the 50 Percent review, building (structural compliance with the Florida Building Code, including wind and flood loads), Department of Health where a septic system is involved, right-of-way and easements, tree (to make sure no heritage trees are removed and replacement trees are shown), and zoning (setbacks and land development rules).
Each one can stop the permit, so the drawings need to answer all of them.
How does the Charlotte County 50% review work?
The county uses the tax assessor's valuation of the structure, excluding land, as market value.
You can hire a state-licensed appraiser for a certified appraisal if you disagree. The contractor and owner sign a Reconstruction/Improvement Cost Breakdown, and the county checks it against the International Code Council's Building Valuation Data. Donated labor and materials count at fair market value, and storm repairs are priced at pre-disaster rates.
Some items are left out of the cost: plans, surveys, permits, sidewalks, pools, screen-roofed cages, sheds, gazebos, fences and septic systems.
If the work is substantial, the lowest finished floor must be at or above the 100-year flood elevation plus one foot. Electrical and mechanical equipment, bathrooms, laundry rooms, water heaters and finished areas go up too; only parking, access and limited storage may stay below. Garages, carports and lanais are not counted as the lowest finished floor.

Charlotte's checklist and the 2025 state law
Charlotte County's remodel checklist still tells applicants that new work is compared with past cumulative work.
That instruction predates section 163.31795, Florida Statutes (ch. 2025-190), which says an NFIP community may not enforce a substantial-improvement ordinance that uses a cumulative period.
In Charlotte County the practical place this shows up is the 50 Percent review station and the Reconstruction/Improvement Cost Breakdown the owner and contractor sign.
If earlier permits on the same building are being added to your total, ask the 50 Percent reviewer which rule is being applied before you trim the scope to fit under the threshold.

Pineland's sequence for a Charlotte County addition
Measure and document the existing building so the drawings clearly show existing and proposed work, as the remodel checklist asks.
Design the structure for the wind and flood loads the building review station checks.
List every window, door, roof covering, siding and soffit by its full product approval number, decimal included.
For commercial buildings that use dry floodproofing instead of elevation, certify the floodproofing plans as the county requires of a Florida registered engineer or architect.
