When it comes to home improvement in Lake Oswego, many homeowners are rolling up their sleeves and taking the DIY route. Whether it’s updating fixtures or unclogging a stubborn drain, doing it yourself can save time and money—if done right. But when it comes to plumbing, there are strict guidelines on what you can and can’t do without a license in Oregon.
Understanding these limitations isn’t just about legality—it’s about protecting your home, health, and finances. If you’re a Lake Oswego resident interested in plumbing DIY, here’s what you need to know.
✅ What You Can Do Without a License
The Oregon Building Codes Division allows homeowners to perform some plumbing work on their own primary residence under specific conditions. You must own and live in the home, and the work must not involve commercial properties or rental units.
Here’s a list of plumbing tasks you can legally tackle yourself:
🔹 Replace Fixtures
Swapping out a leaky faucet or installing a new showerhead is perfectly fine—so long as you’re not modifying the plumbing behind the walls.
🔹 Unclog Drains
Basic drain clearing using plungers, drain snakes, or eco-friendly drain cleaners is allowed and often the first line of defense against slow-moving sinks.
🔹 Repair Leaks on Accessible Pipes
Small leaks under the sink or at the toilet base? You can repair or tighten fittings if you’re not altering the overall piping structure.
🔹 Install or Replace a Garbage Disposal
Many homeowners handle this task themselves. Be sure to disconnect the power, and follow the manufacturer’s instructions closely.
🔹 Replace a Toilet
Toilet swaps are fair game. Just remember to turn off the water, empty the tank, and use a proper wax ring to avoid leaks.
🚫 What You Cannot Do Without a Licensed Plumber
While Oregon encourages some homeowner independence, major plumbing tasks must be performed by a licensed professional. Here’s what’s off-limits:
🔻 Altering Pipe Layouts
Changing the location of a sink, moving a toilet, or adding new water lines? These require permits and a licensed plumber.
🔻 Installing or Replacing a Water Heater
Per Oregon plumbing code, this must be done by a licensed plumber. Incorrect installation can lead to leaks, explosions, or carbon monoxide hazards.
🔻 Working on the Main Sewer Line
Sewer line repairs or clean-outs must be handled by professionals to avoid contamination and ensure proper drainage.
🔻 Gas Line Plumbing
Never attempt to run or repair gas lines on your own—this is dangerous and highly regulated.
