Our Room Addition & ADU Services in Los Angeles
ADU Builder Los Angeles Homeowners Trust
ADUs have become one of the smartest ways to add usable square footage and flexibility to a property. Whether you want space for extended family, guests, a private office, or rental potential, we build ADUs that are tailored to the property and the way you plan to use them.
Our ADU services include detached ADUs, attached ADUs, and conversions of existing spaces. If you are exploring code requirements and recent changes, you can also review our resource on California ADU law updates and our overview of ADUs and accessory dwelling units.
Room Addition Contractor Los Angeles Families Rely On
A well-planned room addition should feel like it has always been part of the home. We build custom room additions for growing families, changing household needs, and homeowners who want more comfort without sacrificing location.
Common projects include new bedrooms, expanded family rooms, primary suite additions, home offices, and larger kitchen-adjacent living areas. When the project calls for broader upgrades, our team can also coordinate complete interior and exterior remodeling, kitchen remodeling, and bathroom remodeling.
Garage Conversion Los Angeles
A garage conversion can be one of the most efficient ways to unlock new living space on an existing property. We help homeowners convert underused garages into ADUs, guest suites, workspaces, or flexible living areas that are designed around function, comfort, and code compliance.
Because every property is different, we evaluate access, utilities, structural conditions, and city requirements early in the process. That upfront planning helps avoid surprises later and keeps the project moving more smoothly.
Second Story Addition
When lot space is limited, going up can be the right solution. A second-story addition can dramatically increase living space while preserving your yard and footprint.
These projects require careful design, engineering, planning, and execution. We work with licensed architects and engineers to create plans that align with your goals, and then we manage construction in a way that protects the integrity of the existing home while delivering a cohesive finished result.
ADU Design and Permits Los Angeles
Every successful addition begins with the right plans. We start each project with blueprints prepared by a licensed architect and/or engineer, and once your layout is approved, we help move the project through plan check and permit approvals.
Our design-build capabilities simplify communication and reduce friction between planning and construction. Learn more about our blueprints and design services and how we support homeowners through approvals, selections, and project execution.

- Skilled in-house crews for quality control

A Process Built for Clarity, Quality, and Efficiency
1. Consultation and Project Discovery
We begin by learning how you want the space to function, what your property allows, and what type of project makes the most sense. Some homeowners need a simple addition. Others benefit more from an ADU, garage conversion, or second-story buildout.
2. Plans, Engineering, and Approvals
Next, we coordinate blueprints with licensed design professionals. Once the floor plans are approved, we help navigate plan check and the permits required for construction.
3. Material Planning and Selections
We then source rough and finish materials needed for the build. That includes windows, doors, plumbing fixtures, electrical fixtures, appliances, cabinets, and flooring, all selected with your design direction, budget, and timeline in mind.
4. Construction by Our In-House Team
Our in-house crew executes the approved plans with a strong focus on craftsmanship, communication, and schedule management. Because the work is closely managed, we maintain better quality control from start to finish.
5. Final Delivery
The goal is not just to add square footage. It is to deliver a space that feels integrated, comfortable, and worthy of your investment.
