Custom ADU Studio

Your backyard has room for a bigger idea. We design the ADU that fits it.

brADU Design is a design studio devoted entirely to accessory dwelling units — from feasibility and design to stamped, permit-ready drawings.

No-risk site review. We'll tell you honestly what your lot can support.

The Process

From first sketch to stamped permit set.

Four clear phases. You always know where your project stands and what happens next.

01 — Feasibility

Site & zoning review

We study your lot, setbacks, utilities, and local ADU ordinances to confirm what you can build — before you spend on design.

02 — Design

Concept & refinement

Floor plans and 3D studies tailored to how you'll actually use the space: rental income, family, office, or all three.

03 — Documents

Permit-ready drawings

Complete construction documents — design drawings, structural coordination, and Title 24 energy — ready for city submittal.

04 — Permitting

City approval

We submit, track, and respond to plan-check comments until your permit is issued and you're cleared to build.

What We Design

Every kind of ADU. Only ADUs.

Specializing means we know the codes, the pitfalls, and the possibilities better than a generalist ever could.

Detached New-Build

Ground-up backyard homes designed around your lot's light, privacy, and access — from compact studios to two-bedroom units.

Garage Conversion

Turn an underused garage into a legal, comfortable dwelling — including existing-structure permitting and code upgrades.

Attached & JADU

Additions, above-garage units, and junior ADUs carved from existing floor area — designed to complement your main home.

Why brADU

Design-first. Detail-obsessed. ADU-only.

An ADU is a small building with big consequences — for your property value, your family, and your neighborhood. We treat it that way.

Work directly with your designer

No hand-offs, no account managers. The person who sketches your concept is the person who answers your calls.

Custom, never cookie-cutter

Every plan starts from your site and your goals — not a catalog. The result is a unit that looks like it was always meant to be there.

Fluent in city plan-check

We speak the language of planning departments and keep up with fast-changing state and local ADU law, so approvals move faster.

Transparent, flat-fee phases

Clear scope and pricing for each phase before it begins. You approve every step; there are no surprise invoices.

Free feasibility consultation

A no-cost, no-pressure conversation about your lot. If an ADU isn't viable, we'll tell you — and tell you why.

Built for return

Whether it's rental income or multigenerational living, we design for long-term value, durability, and low operating cost.

The Studio

Small buildings deserve serious design.

brADU Design was founded on a simple observation: most ADUs are built from generic plans that ignore the lot they sit on. We started this studio to do the opposite — to bring real design thinking to the smallest, most personal buildings people ever commission.

The name says it all. The ADU is right at the center of everything we do.
