Expert ADU Design for Los Angeles Homeowners

Our architectural team specializes exclusively in ADU design across Los Angeles County. We know the local zoning codes, setback requirements, and permit processes inside and out — so your project moves forward without delays.

From junior ADUs to two-story detached units, every design is customized to your lot, your goals, and your budget.

Our Design Process

In-House Architecture — No Third-Party Architects

Our designers and architects work on ADUs exclusively. Every floor plan, elevation, and set of permitted drawings comes from our in-house team — which means faster revisions, tighter coordination with permitting, and zero handoff delays.

  • Site feasibility review before any design work begins
  • 3D renderings so you see the finished ADU before breaking ground
  • Designs optimized for LADBS and LA County plan check approval
  • In-house team handles corrections and resubmissions directly
  • Architectural plans coordinated with structural engineering in-house
  • Design-to-permit handoff in days, not weeks

Common Questions

ADU Plans & Design — Frequently Asked Questions

What Los Angeles homeowners ask most before starting an ADU project.

Do I need a separate architect to design my ADU?
Not with us. Our in-house architectural team handles all design, floor plans, elevations, and permit-ready drawings. No third-party architect required. Having design and construction under one roof means faster revisions, tighter permit coordination, and no handoff delays between your designer and builder.
What does ADU design include?
Our design service includes a site feasibility analysis, floor plan development, exterior elevations, 3D renderings, structural engineering drawings, Title 24 energy calculations, and a full permit-ready drawing set. Everything the city requires for plan check submission is included, no separate engineering contracts.
How long does ADU design take?
Design typically takes 4–6 weeks from kickoff to a permit-ready drawing set. This includes the initial design meeting, floor plan development, your review and approval, and final drawing production. More complex sites or custom designs may run slightly longer. Design and permitting are sequenced so there's no gap between design completion and plan check submission.
Can I customize the design, or do I have to use a pre-designed model?
Both options are available. Pre-designed models are fully customizable, you can modify finishes, cabinets, fixtures, and some layout elements. We also offer fully custom design for homeowners with a specific vision or site requirements that don't fit a standard model. Pre-designed models reduce design time and cost; custom design offers maximum flexibility. We'll recommend the right path after reviewing your property.
What is a 3D rendering and do I need one?
A 3D rendering is a photo-realistic visualization of the finished ADU, exterior and key interior spaces, created before any construction begins. We include 3D renderings in every design engagement. They allow you to review and approve the design with confidence before drawings go to plan check, and they're useful for showing the project to tenants or lenders.
Does your ADU design team understand Los Angeles zoning rules?
Yes. Our team designs ADUs exclusively in Los Angeles County. We know LADBS plan check requirements, LA City zoning overlays, and the specific rules for each city we work in: Culver City, Pasadena, Burbank, West Hollywood, Glendale, and others. Designs that don't comply with local rules don't get approved, we build compliance in from the first draft.
