QUICK ANSWER
Window and Exterior-Door Change-Outs Are Permitted Work in Hernando County.
Hernando County currently lists garage door and window/door change-outs among residential permits that registered contractors can self-issue through the Contractor Portal. The County separately lists glass-only replacement in an existing window or door as exempt when the frame is not being replaced.
- A full window or exterior-door change-out is not the same as replacing glass only.
- Hernando County lists window/door change-outs among residential self-issuance permits for registered contractors.
- Glass-only replacement in an existing frame appears on the County's residential exemption list.
- The written estimate should say whether permit coordination is included.
- Product selection should be confirmed for the actual opening and applicable requirements.
FULL REPLACEMENT
Changing the Window or Door Unit Changes the Permit Conversation.
When the existing unit and frame are being removed and replaced, Hernando County treats the project differently from simple glass repair. The County's contractor guidance specifically lists window/door change-outs as a residential permit type available through its contractor portal.
If you are planning replacement windows or exterior doors, Swift's window and door installation service covers the opening, installation and related finish work as one project scope.
LIMITED REPAIR
Glass-Only Replacement Is Listed Separately.
Hernando County's current residential exemption document includes replacement of existing window and door glass when the project is glass only and the frame is not being changed. That narrow exemption should not be treated as a blanket exemption for replacing the complete unit.
This distinction matters when comparing bids. One contractor may be quoting a repair while another is quoting full replacement. The price difference can be legitimate because the scope is different.
WRITTEN SCOPE
Make Sure the Proposal Covers More Than the Product.
A useful window or door proposal should identify what is being replaced and what surrounding work is included. Depending on the project, that can include removal, opening preparation, flashing or water-management details, installation, interior trim, stucco, drywall and paint touch-up.
- Exact openings included in the project
- Product type and specifications
- Permit responsibility
- Removal and disposal of existing units
- Opening preparation and weather protection
- Interior and exterior finish work

BEFORE INSTALLATION
Verify the Opening, Product and Permit Before Work Begins.
Do not rely on a general statement that a product is “Florida approved.” The installation still has to match the specific opening, approved product information and applicable local requirements. The contractor should also be able to explain who is handling the permit and inspections when they apply.
If you are comparing multiple proposals, use the remodeling estimate comparison guide to compare scope and contractor responsibility rather than looking only at the total price.
