In Lakewood, CA, more and more homeowners are making smart use of their backyards, building ADUs for aging parents, grown kids, or extra rental income. But while the idea might sound simple, the plumbing? Not so much.

That’s where Benjamin Franklin Plumbing of Long Beach comes in. We specialize in ADU plumbing services in Lakewood, handling everything from new water and sewer line connections to fixture installation and city inspections. Whether you’re converting a garage, building from scratch, or adding a backyard cottage, we’ll help you get it done right, on code, on time, and without cutting corners.

Why You Need an Expert for ADU Plumbing in Lakewood

Plumbing for an ADU isn’t like adding a second bathroom. It’s more like building a mini home from the ground up. And when it comes to tying into existing systems, navigating permitting, and meeting Lakewood’s building codes, you need more than a handyman. You need a plumber who knows the process inside and out.

Here’s why hiring an expert matters:

  • Water and sewer connections need to be precisely planned and professionally executed
  • Permitting and inspections require code-compliant work from a licensed contractor
  • Tight spaces and complex layouts demand creative, efficient plumbing solutions
  • Any mistakes can lead to costly delays, failed inspections, or even damage to your main home’s plumbing

At Benjamin Franklin Plumbing of Long Beach, we don’t just install pipes. We guide you through the process from the first blueprint to final inspection, making sure your ADU is functional, legal, and built to last.

Our ADU Plumbing Services Include

Whether you’re building a sleek new backyard rental or converting a garage into a cozy in-law suite, we offer everything you need to bring the plumbing side of your ADU to life safely, smoothly, and to code.

Here’s what we handle:

  • New water and drain line installation
  • Sewer main tie-ins and connections
  • Gas line installation (for stoves, heaters, or dryers)
  • Kitchen and bathroom rough-ins and fixture hookups
  • Water heater installation (tank or tankless)
  • Permitting support and inspection coordination
  • Code-compliant planning and layout guidance

We work closely with general contractors, designers, and homeowners alike to make sure everything flows the way it should, on the blueprint and in real life.

ADU Plumbing That Meets Lakewood’s Codes

When you’re adding an ADU in Lakewood, cutting corners can be risky, costing you time, money, and your final inspection approval. That’s why every job we take on is built around code compliance from the start.

We stay up to date on Lakewood’s local ordinances, Los Angeles County regulations, and all California plumbing code requirements, so your project moves forward without unnecessary delays or red tape.

What you can count on:

  • All work performed by trained and insured service technicians
  • Proper permitting and inspection support
  • Experience with trenchless sewer tie-ins and complex water routing
  • Plumbing layouts designed for long-term function, not just passing inspection
  • Work that’s done cleanly, efficiently, and right the first time

No shortcuts. No surprises. Just plumbing you and your inspector can trust.

Excellent in every respect!

deborah moore

My consultation with your plumber, Kevin, was very pleasant and he was very knowledgeable and explained everything about my pressure tank issues. I have been searching for a plumber who understands pressure tanks on a well system and fortunately, I'm relieved to be putting my confidence in your services. I'm also going to join the service plan for my future plumbing, electric and HVAC. I'm beyond pleased by the convenience of having all of these services provided by one provider and in addition, receiving a discount on all the work as well! Thank you so much! Looking forward to working with you !

Amy Gardner

I would highly recommend Benjamin Franklin plumbing of Northwest Arkansas. Ethan was our technician and was so pleasant and professional to work with. We had a gas leak and BF sent Ethan promptly to our house. He was extremely thorough in finding any and all problems. He showed me everything he was doing and explained it in detail. He was nice enough to give us a phone number if we had any further problems. In addition, he gave us advice about how to stay safe in the future. He relieved a lot of stress for our family. I would not hesitate to call again.

Joshua Kostick

Great service! Cael arrived the same day, found the problem with our toilet, and had a replacement installed within a few hours! Polite and courteous, he was a pleasure to work with!

Anthony Basirico

Matt was a pleasure to have as my water filter installer. He took his time on the install and explained step by step on the installation procedure. He is a top notch technician. The job came out great. I am very pleased with the installation.

Debbie Middleton

A well-intentioned neighbor removed a stuck water hose from my front yard faucet and broke the water pipe in the process. He repaired the break with a shark-bite fitting, which worked for a few hours but started leaking. Well-intentions notwithstanding, I recognized I needed a professional and called Benjamin Franklin. Micah Moore arrived at the appointment time, assessed the damage, and made the repair: he removed the fitting, welded the pipe and installed a new faucet. Micah is skilled, knowledgeable, and personable. He made time to answer my questions and made me feel confident the repair would hold. It was a great experience and as an ancillary bonus, I learned about PVC vs poly and metal pipes and water pressure! Highly recommend.

Zulejha Mustafa

I had a wonderful experience! Their customer service was friendly and professional and they quickly scheduled my appointment. The plumber was knowledgeable, respectful, and explained everything clearly. The work was done efficiently with no hidden fees, making it a truly excellent service. I highly recommend them and will definitely use them again!

Lori Johnson

Delta faucet hose was leaking and Seth creatively made it work while Delta sent us a new faucet. He was ready to put it in as soon as we got it. Great, friendly service

Alicia Berumen

I had an incredible experience with Benjamin Franklin Plumbing. From the moment I called, their customer service was friendly, professional, and prompt. They showed up exactly when they said they would (which is rare these days!), and the plumber was knowledgeable, respectful, and clearly skilled at what he does. He took the time to explain everything to me, made sure I understood the problem and the solution, and got the job done efficiently. Not only was the work done right the first time, but he also left the area cleaner than he found it — which I really appreciated! It’s hard to find a company that truly values its customers and stands by its work, but Benjamin Franklin Plumbing exceeded my expectations. I highly recommend them to anyone needing plumbing help — they’re reliable, honest, and simply the best!

Kelly Bonny

Shawn was great. Polite, kind, and very good at keeping me updated. He did a great job and left the area nice clean.
