If you’re a homeowner in Highlands County, Florida, and your pipes are leaking, corroded, or just outdated, you might be tempted to tackle a full plumbing replacement yourself. After all, YouTube tutorials and home improvement stores make it look simple. But can a homeowner replace a plumbing system in Highlands County, Florida—legally, safely, and effectively? The short answer: sometimes, but with serious caveats. In this guide, we’ll walk you through the legal requirements, hidden risks, cost comparisons, and when it’s truly smarter to call a licensed pro.
Is It Legal for a Homeowner to Replace Plumbing in Highlands County?
Yes—but with restrictions. According to the Florida Building Code (FBC), which Highlands County adopts and enforces, homeowners can perform plumbing work on their primary residence, provided they:
Own and occupy the home as their homestead (not a rental or investment property).
Pull the required plumbing permits from the Highlands County Building Department.
Pass all required inspections (rough-in, final, and pressure tests).
However, if you’re not the legal owner-occupant, or if the work involves sewer lines, gas piping, or water service mains, a state-licensed plumber is mandatory.
💡 Pro Tip: Always verify current rules with the Highlands County Building Services . Regulations can change, and fines for unpermitted work can exceed $500 per violation.
What Plumbing Work Can Homeowners Legally Do?
Not all plumbing tasks are equal. Here’s a quick breakdown:
Replacing faucets, toilets, or showerheads
Installing or relocating water heaters
Fixing minor leaks under sinks
Working on main water supply lines
Installing new sinks or tubs (with existing lines)
Connecting to public sewer or septic systems
Replacing PEX or copper supply linesinside walls(with permit)
Any work involving natural gas lines
⚠️ Warning: Even “simple” pipe replacements can violate code if slope, venting, or material specs aren’t followed. A 2022 study by the Florida Department of Business and Professional Regulation (DBPR) found that 68% of DIY plumbing failures stemmed from improper venting or incorrect pipe sizing—issues that often go unnoticed until major damage occurs.
Step-by-Step: How to Legally Replace Plumbing as a Homeowner
If you’re confident and your project qualifies, follow these steps:
Confirm Eligibility: Ensure you own and live in the home. No rentals or flips allowed.
Get a Permit: Visit the Highlands County Building Department (300 S. Commerce Ave, Sebring) or apply online. Expect to submit a plumbing plan sketch. Permit fees range from $75–$250, depending on scope.
Use Code-Compliant Materials: Highlands County follows the 2020 Florida Plumbing Code, which mandates:
PEX tubing must be ASTM F876/F877 certified
Copper pipes must be Type L or M
All fixtures must meet WaterSense standards
Schedule Inspections:
Rough-in inspection (after pipes are installed but before walls are closed)
Final inspection (after fixtures are installed and system is pressurized)
Pass Pressure Test: Your system must hold 80 PSI for 15 minutes with no drop.
📌 Real Example: In 2023, a Sebring homeowner replaced bathroom plumbing himself but skipped the permit. When selling the house, the buyer’s inspector flagged unpermitted work. The seller had to pay $3,200 to have a licensed plumber redo and certify the system—plus $400 in county fines.
Risks of DIY Plumbing (Even If It’s “Legal”)
Just because you can doesn’t mean you should. Consider these real-world consequences:
Insurance Denial: If a DIY leak causes $20,000 in water damage, your homeowner’s insurance may deny the claim if work was unpermitted or non-compliant.
Health Hazards: Cross-connections or improper backflow prevention can contaminate your drinking water.
Resale Problems: Unpermitted plumbing is a red flag during home inspections. Buyers often demand repairs or price reductions.
Cost Overruns: The average DIY plumbing project goes 35% over budget due to mistakes, per a 2021 HomeAdvisor report.
For context, the average cost to replace a full home plumbing system in Highlands County ranges from $4,000–$15,000 when done by a pro. A botched DIY job can easily cost more in repairs.

Expert Insight: What Local Plumbers Say
“We see homeowners try to save money by replacing pipes themselves, but they often miss critical details like proper slope for drainage or thermal expansion tanks for water heaters. One mistake can lead to mold, structural damage, or even a failed septic system.” — Mark Reynolds, Master Plumber, Sebring Plumbing Co. (22 years in Highlands County)
Q1: Do I need a permit to replace a water heater in Highlands County? Yes. All water heater installations—gas or electric—require a plumbing and/or mechanical permit. Gas lines also need a pressure test.
Q2: Can I replace my sewer line myself? No. Sewer line work (from house to main) must be done by a state-licensed plumber with a Class A or B plumbing license. This includes septic tank connections.
Q3: How long does a plumbing permit last in Highlands County? Permits expire after 180 days of inactivity. If you don’t schedule an inspection within that window, you’ll need to reapply and pay again.
Q4: Are PEX pipes allowed in Highlands County? Yes. PEX is approved for residential use under the Florida Plumbing Code, as long as it’s rated for potable water and installed per manufacturer specs.
Q5: What happens if I don’t get a permit? You risk fines, forced removal of work, insurance denial, and complications when selling your home. The county can also place a lien on your property.
Q6: Can I hire an unlicensed “handyman” to do plumbing? Only if the work is minor (e.g., unclogging a drain, replacing a faucet washer). Any pipe replacement, new fixture installation, or system modification requires a licensed plumber.
Conclusion
So, can a homeowner replace a plumbing system in Highlands County, Florida? Technically, yes—if you’re the owner-occupant, pull permits, follow code, and pass inspections. But in practice, the risks often outweigh the savings. Plumbing isn’t just about connecting pipes; it’s about ensuring safety, efficiency, and long-term home value.
If your project is small (like a single fixture), DIY might work. But for whole-house replacements, aging pipe systems, or anything involving water mains or sewer lines—hire a licensed professional. Your wallet, your family’s health, and your future home sale will thank you.
