ADU Construction Company in San Pedro, CA9

An ADU idea is exciting. Turning that idea into a finished home is where the real work begins.

Ground preparation, foundations, framing, roofing, plumbing, electrical systems, insulation, kitchens, bathrooms and final finishes all need to come together correctly. Without proper coordination, what looks straightforward on paper can quickly become a complicated construction project.

Baumeister Construction provides professionally managed ADU construction for homeowners across San Pedro. We take your project from preparation through the major building stages to final completion, with quality workmanship, direct communication and accountability throughout.

Whether you’re planning a detached backyard residence, converting a garage or adding a connected living unit, we focus on building a space that is practical, durable and ready for real life.

Too Many Moving Parts. One Construction Team.

Building an ADU can involve designers, permit requirements, groundworks, structural trades, electricians, plumbers, roofers, installers and finishers.

When those responsibilities are fragmented between different people, homeowners can find themselves becoming the project manager.

That’s not what you signed up for.

Baumeister Construction provides a more coordinated approach.

We establish the scope before construction progresses, organise the required building stages and keep communication clear as work moves forward.

Instead of spending your time chasing different trades and wondering who is responsible for the next step, you have an accountable construction company overseeing the project.

That means fewer unanswered questions, clearer responsibility and a better-managed route from plans to finished living space.
