How We Work for Your Custom
ADU Architectural Design
At Irvine Elite ADU Builder, we base our process on precision, collaboration, and technical expertise. Our systematic approach ensures every ADU design is functional, compliant, and visually refined. Licensed architects and engineers manage each phase using advanced tools and proven methods to achieve exceptional results. Here’s how we create your custom ADU architectural design:
Step 1: Initial Consultation and Site Understanding
We start with an in-depth consultation to understand your goals, preferred layout, and budget. Our design specialists conduct a full on-site assessment in Irvine, CA, using laser measuring equipment, soil condition checks, and zoning data analysis to define the project parameters. This step allows us to identify spatial opportunities, utility access points, and environmental considerations crucial for accurate design planning.
Step 2: Conceptual Design and Space Planning
Our architects use CAD (Computer-Aided Design) and BIM (Building Information Modeling) software to create a detailed conceptual design that maximizes space, ventilation, and natural light. We present multiple design options showing room configurations, circulation flow, and elevation profiles. Each concept is reviewed against Irvine’s ADU zoning guidelines to ensure compliance before moving forward.
Step 3: Structural Detailing and Material Specification
We prepare complete architectural drawings, including detailed floor plans, foundation layouts, and cross-section views. Our team specifies materials such as reinforced concrete for foundations, structural-grade timber or steel for framing, and energy-efficient insulation that meets California’s Title 24 requirements. Every component is chosen for long-term durability, strength, and modern appeal.
Step 4: Design Review and Client Collaboration
We hold structured design review meetings with you to discuss visual and functional details. Using 3D digital modeling and photorealistic renderings, we show how your ADU will look in its final form. Adjustments are made based on your feedback to ensure the design fully aligns with your vision and site conditions.
Step 5: Documentation and Permit Preparation
Our documentation team compiles all architectural and structural plans, energy compliance forms, and technical reports required by the City of Irvine. We verify that each drawing meets California Building Code and local ADU standards. All documents are formatted digitally for direct submission to city officials, reducing the risk of revision delays.
Step 6: Final Design Delivery and Project Handoff
Once approved, we provide the complete design package, including scaled drawings, technical details, and 3D files ready for construction. We also offer step-by-step guidance on the permitting and contractor coordination process. The final output is a build-ready ADU design that reflects accuracy, efficiency, and architectural excellence.
Custom ADU Architectural Design We Offer
At Irvine Elite ADU Builder, we deliver custom ADU architectural design solutions built on precision, innovation, and compliance with Irvine’s zoning and construction standards. Each ADU will match the property’s structural potential, aesthetic character, and intended function. Our licensed architects and engineers use advanced design software, high-performance materials, and sustainable construction methods to create durable and efficient living spaces. Here are the custom ADU architectural design services we offer:
Detached ADU
Architectural Design
We design detached ADUs for homeowners who want a private, self-contained living space that seamlessly complements their main home. These structures use reinforced concrete foundations, energy-efficient framing, and composite roofing materials for long-lasting strength and weather resistance. Each layout is optimized for privacy, natural light, and accessibility while meeting Irvine’s setback, height, and lot coverage regulations.
Attached ADU
Architectural Design
For properties with limited space, our attached ADU designs utilize shared walls and efficient structural integration. We use fire-rated gypsum walls, insulated shear framing, and acoustic barriers to ensure safety, comfort, and compliance with building separation codes. We design these units to align with the home’s architecture while improving overall energy efficiency.
Garage Conversion
ADU Design
Our garage conversion ADU service transforms existing garages into livable spaces built to California’s residential standards. We reinforce existing slabs, install closed-cell spray foam insulation, moisture-resistant flooring, and upgraded electrical and plumbing systems to create a fully functional living unit. This approach maximizes space utility while keeping construction costs manageable.
Two-Story ADU
Architectural Design
We engineer our two-story ADU designs for homeowners who want to build upward, ensuring structural strength and efficient space utilization. We use steel-reinforced framing, load-bearing wall systems, and lightweight composite materials to support vertical expansion. These ADUs are ideal for multi-generational households or rental units, combining visual appeal with full compliance with Irvine’s height and zoning limits.
Junior ADU
(JADU) Design
Our JADU designs focus on compact units built within the existing home structure, such as converted basements or interior sections. We apply space-saving layouts, modular cabinetry, and integrated ventilation systems to maximize comfort and livability. Each JADU complies with California’s state housing laws and Irvine’s residential design requirements.
Commercial Property
ADU Design
We design commercial ADUs for property owners seeking to repurpose existing office or retail spaces into residential or mixed-use developments. Our architects incorporate fire-rated partitions, acoustic insulation panels, and compliant egress systems to meet both commercial and residential standards. This solution increases property functionality and supports Irvine’s demand for flexible housing opportunities.
