Modern detached ADU with warm wood siding, large windows, and landscaped entry

Additions

Accessory Dwelling Units (ADUs)

An ADU is one of the most useful things you can add to a property — a place for family, a rental, or a home office that pays for itself over time. It is also a real construction project with its own permitting path. We manage both sides.

California has opened the door to ADUs, but the details still vary city to city — setbacks, height limits, utility connections, and fire access all shape what is possible on your lot. We start by confirming what your parcel actually allows, so the design is grounded in reality from day one.

We build detached ADUs, attached units, and garage conversions. Each is a complete small home: foundation, framing, kitchen, bath, and its own systems. Because we design and build, the unit is planned to be efficient to construct and comfortable to live in — not just to pass plan check.

From feasibility and drawings through permits, construction, and final sign-off, you have one team accountable for the outcome.

Design & build

How your project comes together

Every project follows the same clear path — so you always know what’s happening and what comes next.

  1. 01

    Consultation

    Week 1

    We visit your home, listen to how you live in it, and talk honestly about scope, priorities, and budget. You leave knowing whether we’re the right fit — no pressure, no vague promises.

  2. 02

    Design & Selections

    Weeks 2–6

    We develop the plan, produce drawings and 3D views, and guide your material and finish selections. Locking these in early is what keeps the budget and schedule honest once we build.

  3. 03

    Estimate & Agreement

    Before we build

    You receive a detailed written estimate tied to a defined scope and real selections — not placeholders. When you approve it, the number you sign is the number we build to.

  4. 04

    Permits & Engineering

    Varies by city

    We prepare complete submittals, coordinate structural and mechanical engineering, and manage plan check and corrections so your project clears review as smoothly as possible.

  5. 05

    Construction

    Project-dependent

    One project manager owns the schedule and communication. Trades are sequenced so they don’t collide, the site stays protected and clean, and you always know what’s happening this week.

Honest answers

What homeowners think about first

The questions worth asking before you start — answered straight.

Will an ADU fit on my lot?

Most residential lots can accommodate some form of ADU, but setbacks, existing structures, and utility locations decide the size and placement. Our first step is a feasibility review so you know your options before investing in full design.

How long does the permitting take?

State law has streamlined ADU approvals, but timelines still vary by jurisdiction. We prepare complete, code-correct submittals to reduce plan-check cycles, and we keep you updated on where the application stands.

Detached, attached, or garage conversion?

A garage conversion is often the most economical path; a detached unit offers the most privacy and flexibility. We help you weigh cost, yard impact, and long-term value for your specific property.

FAQ

ADUs questions

How much does an ADU cost to build?

Cost depends on type (garage conversion vs. detached), size, finishes, and site conditions such as utility runs and grading. We provide a written estimate after feasibility and preliminary design so the number reflects your lot, not an average.

Do you handle the permits?

Yes. We manage design, structural engineering, permit submittal, plan-check corrections, and inspections through final sign-off.

Can an ADU have its own address and utilities?

Typically yes. Separate entrances, addressing, and metering are common; the specifics depend on your city and utility provider, which we confirm during feasibility.

Can I convert my garage into an ADU?

Often, yes — garage conversions are a popular and cost-effective ADU path. We assess the existing slab, walls, and utilities to confirm feasibility.
