Permit requirements, timelines, fees, procedures, interpretations, and enforcement practices vary by jurisdiction and may change without notice. Always verify current requirements with your local building department and, when appropriate, consult a licensed contractor, architect, engineer, attorney, or other qualified professional before starting any project.

Before you break ground, you need to know that not all permits are created equal. In Florida, construction permits follow a specific hierarchy. Understanding the difference between a Master Permit and a Sub-permit can be the difference between a smooth project and a costly permitting headache.

Quick Reference

Master Permit
Covers the overall project.
Quick test: the project affects the structure or use of the building.
Examples: additions, new construction.

Sub-Permit
Covers specialized trades.
Quick test: specialized work that’s typically tied to a Master Permit — though in some cases it can be pulled as standalone if there’s no major construction involved.
Examples: Electrical, Fire Alarm, Plumbing.

Standalone Permit
For independent work.
Quick test: isolated work that doesn’t require a Master Permit.
Examples: HVAC replacement, water heater replacement.

1. The Master Permit (Building Permit)

Think of the Master Permit as the “umbrella.” It is the main authorization for the overall project.

• When is it used? For major projects like new construction, additions, or structural remodels.
• Who holds it? Usually the General Contractor (GC).
• Why it matters: Trade permits are typically associated with the master permit so the jurisdiction can review and inspect the project as a coordinated whole.

Before applying, make sure you have everything ready — see our guide on what documents are needed for a Florida permit application.

2. Sub-permits (Trade Permits)

Even if you have a Master Permit, specific specialized work requires Sub-permits. These are typically pulled by licensed specialists, contractors, or other authorized parties depending on the jurisdiction and project type. Here’s how they break down:

Building Trades

• Electrical: For wiring, panels, or new outlets.
• Plumbing: For water lines, sewer connections, or water heaters.
• Mechanical: For HVAC (Air Conditioning) systems — in many municipalities this category also covers ventilation, exhaust fans, and fuel-burning equipment, so check with your local department if your project overlaps with Gas work.
• Gas: For water heaters or ranges powered by natural gas or propane.
• Roofing: For re-roofing, roof repairs, or replacement of roof-mounted equipment.

Life Safety Systems

• Fire Sprinklers: For fire suppression systems and sprinkler line installation or modification.
• Fire Alarm: For fire detection, notification, and monitoring systems — reviewed separately by the local fire marshal to meet life-safety code.

Specialty Permits

• Low Voltage / Security: For cameras, access control, and other low-voltage security wiring.
• Pool & Spa: For pool and spa equipment — pumps, heaters, and electrical bonding/grounding.
• Solar / Photovoltaic (PV): For solar panel installations and other energy systems.
• Irrigation: For sprinkler systems and related site work.

This list covers the most common sub-permit categories homeowners encounter — it isn’t exhaustive. Many counties also issue sub-permits for specialty work like elevators, backflow preventers, awnings, or signage. When in doubt, ask your local building department which trade permits apply to your project.

Required sub-permits generally must receive final approval before the Master Permit can receive its Certificate of Occupancy or Completion — this is one of the most common causes of project delays.

3. Standalone Permits

Sometimes, you don’t need a Master Permit because the job is specific and doesn’t affect the structure of the house.

• Examples: Water heater replacements, AC replacements, re-roofing or roof repairs that don’t involve structural work or decking, or other trade-specific work that does not require a building permit. If the project involves structural elements or decking, it typically requires a Master Permit instead. These are often called “Express Permits” or “Over-the-Counter Permits” in many Florida cities because they require less intensive review.

Fire protection systems may be submitted as standalone permits or linked sub-permits depending on the project type and local requirements.

4. Special Permit Types in Florida

• After-the-Fact (As-Built) Permit: Used to legalize work already done without a permit. Expect double fees and rigorous inspections.
• Demolition Permit: Required before you tear down any structure or even a large portion of an interior.
• Tree Removal Permit: In many Florida jurisdictions, you cannot cut down a large tree (especially Oaks) without a specific environmental permit.

5. Owner-Builder Permits

Under Florida law, a property owner may act as their own contractor on certain projects without holding a contractor’s license. This exemption is limited: the owner must personally appear and sign the permit application, must provide direct on-site supervision of the work, and is the party legally and financially responsible for the project. Selling or leasing the property within 1 year of completion may create a legal presumption that the work was performed for purposes of resale rather than personal use.

6. How Long Is a Permit Valid?

Permits for single-family homes typically expire one year after issuance, or on the effective date of the next Florida Building Code edition — whichever is later. Exact requirements and available extensions vary by jurisdiction. Source: City of Fort Lauderdale, HB 803 Quick Guide.

Master the Maze of Florida Permitting

The hierarchy of permits is one of the most common places where homeowners get lost. Does your project need a Master Permit or just a standalone Electrical permit?

In my book, “How to Get a Construction Permit in Florida,” I walk you through exactly how Master Permits and Sub-permits connect — using a real-world kitchen renovation example — so you understand why a project can stall when the master permit is paused, and what that means for every trade permit tied to it.
