ADU

Residential Building with a Purpose

ADUs Built Thoughtfully for What Matters Most

Thoughtfully Built Spaces, Designed Around Your Life

At CAZ Construction, we believe your property should work for you—whether that means more space for family, extra income, or just greater flexibility in how you live. Accessory Dwelling Units (ADUs) are one of the most effective ways to unlock that potential without losing the heart of what makes a home feel like home.

We don’t just build structures—we build spaces that add lasting value, comfort, and opportunity.

Your Partner in ADU & Residential Expansion

We don’t just build additional space—we help you unlock your property’s full potential. From feasibility and design through permitting and final inspection, we’re by your side with:

Strategic planning tailored to your lot, zoning, and long-term goals

Clear guidance through permits, utilities, and local requirements

Transparent timelines and pricing you can trust

A commitment to craftsmanship, functionality, and lasting value

Whether your ADU is for family, flexibility, or future income, we approach every project as a true partnership—built on clarity, communication, and care.

How We Help You Build an ADU That Works

We take a full-service approach to ADU planning and construction so you never have to juggle permits, zoning, design details, or contractors on your own. Here’s what we guide you through:

1. Lot Evaluation & Feasibility

We help you determine what’s possible on your property—from attached units and detached cottages to conversions or junior ADUs—based on local zoning, setbacks, and utility requirements.

2. Design & Planning

Your ADU should feel like a natural extension of your home and landscape. We collaborate with designers to create a space that suits your lifestyle and budget.

3. Permitting & Code Navigation

Building an ADU means interacting with city departments, submitting plans, and complying with building codes. We handle those steps and make sure approvals move smoothly.

4. Construction & Project Management

From foundations and framing to finishes and inspections, we manage every phase of construction so you can focus on the excitement of seeing your planned ADU come to life.
