Do You Need a Permit for Plumbing or Septic Work in Georgia?

Quick answer: In Georgia, a permit is required for most significant plumbing and septic work — including water heater replacements, sewer line work, gas lines, repiping, and any septic tank installation or repair. Minor repairs — fixing a faucet, unclogging a drain, swapping a toilet, or patching a small leak — usually don’t need one. Permits are issued through your county building or health department.

Here’s what needs a permit, what doesn’t, and why it matters for North Georgia homeowners.

What plumbing work needs a permit in Georgia?

Permit rules are set at the county and city level, but these jobs almost always require one:

• Water heater replacement (tank or tankless)
• Sewer line repair or replacement
• Gas line installation or modification
• Repiping or new water supply lines
• Adding or moving fixtures, drains, or bathrooms
• Backflow preventer installation

What plumbing work usually doesn’t need a permit?

• Fixing or replacing a faucet
• Repairing a running or leaking toilet (or swapping the toilet itself, in many jurisdictions)
• Unclogging a drain or line
• Replacing a garbage disposal
• Minor leak repairs

When in doubt, a licensed plumber knows your county’s rules and will tell you.

What about septic permits?

Septic work is regulated by the county health department (through the Georgia Department of Public Health), and permits are required for:

• Installing a new septic system
• Replacing a tank or drain field
• Major repairs to the system
• Often, adding a bedroom that increases the system’s required capacity

Routine pumping and inspection do not require a permit.

Why permits matter (don’t skip them)

• Safety and code compliance — permitted work is inspected to ensure it’s done correctly, protecting your home and water.
• Home sale problems — unpermitted work often surfaces during a sale and can kill or delay the deal, or force you to redo it.
• Insurance — claims can be denied if damage traces back to unpermitted, non-code work.
• Warranties — many manufacturer warranties require code-compliant, permitted installation.

A reputable, licensed plumber or septic contractor pulls the permit for you as part of the job — you shouldn’t have to handle it yourself.

Frequently Asked Questions

Do I need a permit to replace a water heater in Georgia? Yes, in most jurisdictions. A licensed plumber typically pulls the permit as part of the installation.

Do I need a permit to replace a toilet or faucet? Usually no — these are minor repairs. Check your local rules, but most jurisdictions don’t require a permit for a like-for-like swap.

Who pulls the permit — me or the plumber? A licensed plumber or septic contractor pulls it for you. If someone asks you to pull the permit as the homeowner, that can be a red flag they’re not licensed.

Do I need a permit to install a septic system in Georgia? Yes. Septic installation, tank or drain field replacement, and major repairs require a county health department permit and inspection.

What happens if plumbing work is done without a permit? It can cause problems at resale, void insurance or warranties, and may have to be redone to code. Permitted work protects you on all fronts.
