A Florida Keys window or door project should start with jurisdiction, not with a generic permit form.
Monroe County operates its own online permitting system for county-issued permits, while incorporated municipalities can have separate permitting responsibilities. Confirm which building department controls the actual property before preparing the application.
How does Monroe County accept permit applications?
Monroe County’s Building Department uses OPAL — Oracle Permitting and Licensing for online permitting.
The County states that permit applications and document submissions are handled through the web-based system and that users involved with an application should register for access.
That means project records should be organized digitally from the beginning.
What should be prepared for an impact-window or door project?
The exact checklist comes from the permitting authority, but a useful project file should identify:
- Property address and jurisdiction
- Existing opening locations
- Proposed opening sizes
- Manufacturer and product series
- Florida Product Approval or other applicable approval
- Impact classification
- Glass configuration
- Positive and negative design pressures
- Installation details
- Anchors and substrate
- Required plans or engineering
- Inspection and closeout requirements
Our Florida Product Approval guide explains why the exact product configuration matters.
Why is jurisdiction especially important in the Keys?
“Florida Keys” is a regional description, not a single permitting office.
A property may be in unincorporated Monroe County or within an incorporated municipality that uses its own building department and procedures.
Do not assume a Key West, Marathon, Islamorada or Key Largo mailing address automatically tells you which permit workflow applies. Verify the parcel and permitting authority first.
What about historic properties?
Some Keys properties can have historic-preservation requirements in addition to building-code requirements.
Monroe County Historic Preservation Commission records show that impact-window and impact-door replacements can require review when a property is within a designated historic district.
Those records also illustrate an important point: an impact-rated product can still raise architectural compatibility questions unrelated to its hurricane performance.
If the property is historic or in a regulated district, confirm preservation review before ordering.
What about floodplain requirements?
The Florida Keys have extensive flood-risk areas.
A window replacement does not automatically create a floodplain issue, but projects that alter walls, openings or other building elements can intersect with floodplain and substantial-improvement rules depending on scope and property.
Do not rely on a generic internet answer. Ask the permitting authority whether the proposed work triggers additional review for the actual site.
Are impact windows automatically approved because they are “hurricane rated”?
No.
The product must still match the approved configuration and the conditions required for the project.
Verify:
- Approval number
- Manufacturer
- Series and model
- Maximum approved size
- Impact status
- Glass option
- Design-pressure capacity
- Fastener and anchoring requirements
- Substrate
- Any limitations of use
See our HVHZ vs Wind-Borne Debris Region guide for broader Florida wind-zone terminology.
What should homeowners keep after the project?
Keep the digital permit record together with:
- Approved plans
- Product approvals
- Installation instructions
- Inspection results
- Permit closeout
- Warranty information
- Product labels or photos of labels
- Maintenance guidance
That documentation can be useful later for insurance, repairs, resale and future renovations.
Frequently asked questions
Does Monroe County use online permitting?
Yes. Monroe County publishes OPAL as its online permitting system for county-issued permits.
Does every Florida Keys property use Monroe County’s permit office?
No. Incorporated municipalities can have their own permitting authority. Confirm jurisdiction for the property.
Can historic-district rules affect impact-window replacement?
Yes. Monroe County preservation records show window and door replacement projects in historic districts can require separate review for architectural compatibility.
Is a Florida Product Approval enough by itself?
No. The exact approval has to match the product, size, glass, pressures and installation conditions for the project.

The bottom line
For a Florida Keys impact-window project, first confirm the permitting jurisdiction. Then match every opening to the exact approved product and check whether historic, structural or floodplain review applies to the actual property.
