The real first step
MOST PEOPLE READY TO BUILD DON'T REALIZE THE PLANS COME FIRST.
Before permits, financing or construction can move, your ADU needs architectural drawings, structural engineering and an approved permit set. Starting there keeps the project from stalling later.
We take your property from idea to a complete, permit-ready plan set so the day the city approves it, your build is ready to move.

Sample ADU floor plans
START WITH A LAYOUT THAT FITS HOW YOU WANT TO LIVE.
Every property is different, but these sample ADU floor plans show the kinds of layouts we can adapt to your lot, setbacks, access, budget and intended use.
One-bedroom ADU floor plans
Efficient 1-bedroom ADU
A strong fit for rental income, aging parents, adult children or a private guest suite. The layout prioritizes a full living area, functional kitchen, private bedroom and full bath.
1 Bedroom1 BathOpen KitchenRental-Friendly
Two-bedroom ADU floor plans
Flexible 2-bedroom ADU
More privacy and long-term flexibility for families, roommates or higher-value rental use. We can optimize circulation, storage and bedroom placement around the footprint your lot allows.
2 Bedrooms1–2 BathsFamily-FriendlyFlexible Footprint
Detached ADU floor plans
Standalone backyard ADU
A purpose-built detached unit gives you freedom to create a truly independent home. We design around lot access, privacy, natural light, parking conditions and your backyard layout.

Garage conversion floor plans
Convert existing square footage
Garage conversions can turn underused space into a studio, one-bedroom ADU, guest suite or long-term rental while working within much of the existing building footprint.

Sample floor plans shown on this page are conceptual examples for planning and inspiration only. Your actual ADU plans and blueprints must be designed for your specific property and approved by the applicable jurisdiction.

ADU blueprints & permit plans
MORE THAN A FLOOR PLAN. A BUILDABLE, PERMIT-READY SET.
A floor plan is only one part of the job. Your final ADU blueprint package needs the technical information required for plan review, engineering and construction.
- Architectural plans: floor plans, dimensions, elevations and building details.
- Site plan: placement, setbacks, access and relationship to the existing property.
- Structural engineering: framing, foundation and structural details as required.
- Title 24 documentation: California energy-compliance coordination.
- Permit package: coordinated sheets prepared for municipal plan review.
- Plan-check revisions: responses and updates through the city review process.
