How to Pull a Plumbing Permit in Florida

A plumbing permit is required for most plumbing work in Florida beyond simple fixture swaps. Re-piping, water heater replacements, moving or adding fixtures, and sewer line repairs all require a permit and inspection. The Florida Building Code's plumbing requirements protect your home's water quality, prevent sewer gas leaks, and ensure drainage systems work properly. Here's how to navigate the plumbing permit process in any Florida county.

What Plumbing Work Requires a Permit in Florida?

The Florida Building Code requires a permit for any plumbing work that involves:

• Water heater replacement or installation (including tankless conversions)
• Re-piping (replacing supply lines throughout the home — very common in Florida homes with polybutylene or galvanized pipes)
• Moving or adding fixtures (relocating a toilet, adding a bathroom, moving a kitchen sink)
• Sewer line repair or replacement
• Gas line work (natural gas or propane piping)
• Backflow preventer installation (required for irrigation systems connected to potable water)
• Water softener or filtration system installation (when it involves modifying supply piping)

Work that typically doesn't need a plumbing permit includes replacing a faucet, replacing a toilet (same location, same connections), clearing a drain clog, and replacing a showerhead. The key distinction is whether you're modifying the piping system or just changing a fixture connected to it.

Who Can Pull a Plumbing Permit in Florida?

Similar to electrical work, plumbing permits in Florida must be pulled by a licensed plumbing contractor (CFC — Certified Plumbing Contractor, or RPC — Registered Plumbing Contractor). Homeowners can pull an owner-builder permit for plumbing work on their own primary residence, but many counties discourage or restrict this because improper plumbing can contaminate drinking water and create health hazards.

General contractors can include plumbing in their scope of work but must subcontract the actual plumbing installation to a licensed plumber. The plumber typically pulls the plumbing sub-permit as part of the project.

How Much Does a Plumbing Permit Cost in Florida?

Plumbing permit fees in Florida depend on the project type:

• Water heater replacement: $50–$125
• Fixture additions (per fixture): $25–$75
• Re-piping (whole house): $150–$350
• Sewer line repair/replacement: $100–$250
• Gas line installation: $75–$200
• Backflow preventer: $50–$100

In Hillsborough County, water heater permits are among the most commonly pulled plumbing permits, running about $75–$100. Pasco County and Polk County are similar. For a full comparison across all permit types, check our Florida building permit costs guide.

How Do You Pull a Plumbing Permit?

The process is straightforward in most Florida counties:

• Step 1: Your licensed plumber applies for the permit through the county's online portal or in person at the building department. They provide their license number, the property address, and a description of the work.
• Step 2: For simple projects (water heater replacements, fixture swaps), many counties approve the permit same-day or next-day. For complex work (re-piping, sewer line replacement), plan review may take 3–5 business days.
• Step 3: Work begins after the permit is issued. The permit card is posted at the job site.
• Step 4: Inspections are scheduled at required stages (see below).
• Step 5: After passing the final inspection, the permit is closed.

Most plumbing permits in Pinellas County, Lee County, and Duval County can be applied for online, making the process fast and convenient for your plumber.

What Inspections Are Required for Plumbing Work?

The number of inspections depends on the project type:

• Water heater replacement: One final inspection — the inspector checks proper venting (gas units), seismic strapping, TPR valve and discharge pipe, electrical connections (electric units), and clearances.
• Re-piping: A rough-in inspection (before walls are closed, to verify pipe sizing, material, and connections) plus a final inspection (after everything is connected and tested).
• Fixture relocations: Rough-in inspection for new drain and supply lines, plus a final inspection after fixtures are installed.
• Sewer line work: An inspection before the trench is backfilled, verifying proper slope, material, and connections.

Plumbing rough-in inspections must happen before walls are closed. This is the same critical timing rule as electrical inspections — close the walls before the inspection, and you'll be opening them back up. If your project involves both plumbing and electrical work (like a bathroom remodel), both rough-in inspections can often be scheduled at the same time.

Common Plumbing Permit Issues in Florida

These are the most frequent problems Florida homeowners encounter with plumbing permits:

• Polybutylene pipe replacement: Homes built between 1978 and 1995 may have polybutylene (poly-B) supply pipes, which are prone to failure. Full re-piping is common and requires a permit. Insurance companies in Florida are increasingly requiring poly-B replacement.
• Water heater code changes: Florida's energy code and installation requirements have changed significantly. A replacement water heater must meet current code even if the old one didn't — including expansion tanks, proper venting clearances, and pan/drain requirements.
• Unpermitted water heater installations: Water heaters are one of the most commonly replaced items without a permit. This gets caught during four-point inspections and can cause insurance issues. Read our guide on building without a permit for the full consequences.
