Our Attached ADU Configuration Options

Southern California’s Premier ADU Builders

Expand Your Living Space, Enhance Your Property Value

An Attached Accessory Dwelling Unit (ADU) is a physical extension of your primary residence, designed to blend seamlessly with your home’s existing architecture. Unlike detached structures, an attached ADU shares at least one common wall with your main house, making it an incredibly efficient way to add square footage, maximize underutilized space, and increase your property’s overall footprint. Whether you are looking to build a multi-generational living suite for aging parents, create a private wing for adult children, or design a premium work-from-home sanctuary, our team delivers custom attached ADUs that look and feel like they were part of your home’s original blueprint.

The Benefits of Building an Attached ADU

We provide a seamless, end-to-end design-build process, eliminating the stress of dealing with separate architects, engineers, and municipal permit offices.

Choosing an attached ADU offers distinct structural, financial, and lifestyle advantages:

  • Cost-Effective Infrastructure: Because the unit connects directly to your main home, we can often tap into existing plumbing, electrical, and HVAC infrastructure more efficiently than building a standalone structure from scratch.

  • Seamless Living for Families: It provides the perfect balance of proximity and privacy. Family members are just a doorway away, yet enjoy their own private living areas, kitchenettes, and bathrooms.

  • Yard Space Preservation: If you have a smaller lot or want to keep your backyard, pool, or landscaping completely intact, an attached ADU utilizes side yards or vertical space instead of taking over your lawn.

  • Immediate Property Appreciation: Adding livable, permitted square footage directly to your main structure instantly boosts your home’s total appraised value.

Our Attached ADU Configuration Options

Every property is unique, which is why we offer versatile design solutions to fit your specific layout and structural goals:

Bump-Out Extensions (Ground-Level Additions)

We extend your home’s footprint outward into a side yard or rear patio area. This creates a brand-new, ground-level living suite complete with its own private exterior entrance, ideal for easy accessibility and long-term comfort.

Second-Story Additions

If your lot size is limited, we build up. Adding an attached ADU above a garage or as a second-story wing offers stunning views, maximum privacy, and leaves your outdoor backyard space completely untouched.

Junior ADUs (JADUs) & Internal Conversions

By transforming an existing guest wing, large master suite, or attached garage, we can create a Junior ADU (up to 500 sq. ft.). This layout utilizes the existing building envelope, making it one of the fastest routes to city approval and completion.
