Orange County Master ADU Construction

Orange County Master ADU Construction provides a turnkey approach to accessory dwelling unit (ADU) projects, handling design, planning, permitting, construction, and project management. Founded in 2010 by a master builder and architectural designer, the company specializes exclusively in ADU construction and says it has completed more than 250 projects throughout Orange County.

An accessory dwelling unit — also referred to as a granny flat, in-law suite, backyard cottage, or secondary dwelling unit — is an additional independent living space located on the same property as a primary residence. Orange County Master ADU Construction works with several main types of ADUs:

1. Detached ADU: A standalone structure constructed separately from the primary residence. The company provides site evaluation, architectural planning, permitting, structural work, and complete construction for new detached ADUs.
2. Garage Conversion: The company converts attached or detached garages into permitted living spaces, typically incorporating insulation, plumbing, electrical upgrades, HVAC, windows, and other residential improvements required for a functional ADU.
3. Attached ADU: An ADU connected to the primary residence, designed with separate living areas, entrances, and appropriate utility systems while maintaining integration with the existing home.
4. Junior ADU: A smaller independent living unit, generally created within an existing home footprint. The company designs JADUs with efficient kitchens, bathrooms, and flexible living or sleeping areas while addressing applicable local requirements.

What Orange County Master ADU Construction Offers Beyond Construction

Orange County Master ADU Construction presents itself as an ADU-exclusive design-build company, rather than a general contractor that occasionally builds ADUs. Its services begin with site evaluation and feasibility analysis, examining lot configuration, existing structures, utilities, topography, solar orientation, and other conditions that can influence ADU placement and design.

The company provides custom ADU architectural design and planning, including floor plans, elevations, structural details, mechanical systems, construction documents, 3D visualizations, and permitting strategies. Its design process focuses on making efficient use of smaller footprints while addressing zoning, setbacks, utilities, energy requirements, and the relationship between the new unit and the existing home.

Permitting and code compliance are also part of its service. The company states that it manages documentation and submissions to local building departments and assists with requirements involving setbacks, lot coverage, parking, height restrictions, California Title 24, fire safety, utility connections, and other municipal regulations.

During construction, Orange County Master ADU Construction provides project management and turnkey construction services, coordinating the various stages from approved plans through final inspection. Its garage conversion services can include structural modifications, foundation assessments, electrical-panel upgrades, plumbing, HVAC, insulation, windows, and interior finishes.

The company also highlights energy-efficient construction, 3D building models, GIS mapping, soil testing, durable materials, and construction warranties as part of its approach. It states that its projects typically take approximately four to six months, although timelines vary depending on the project.
