ADU Builders in San Diego, CA – Garage Conversions & Backyard Units

Accessory Dwelling Units (ADUs) offer San Diego homeowners a smart, stylish, and high-value way to expand their living space. Whether you’re planning a modern backyard cottage, a luxury guest suite, or a complete garage conversion, Woolsey Construction delivers beautifully designed, expertly built ADUs tailored to your property and lifestyle. Our team handles everything from feasibility to final finishes, ensuring your ADU is efficient, functional, and built to the highest standards.

Custom ADU Design & Build Solutions

Every ADU begins with a vision. We collaborate with architects, designers, and homeowners to create customized plans that maximize space, natural light, and comfort. From coastal-inspired studio layouts to spacious two-bedroom backyard units, each ADU is crafted with attention to flow, privacy, and long-term functionality.

Our design-build approach streamlines the entire process, giving you one trusted team from start to finish. This means faster timelines, fewer surprises, and a seamless experience as your ADU comes to life.

Garage Conversion ADUs

Garage conversions are one of the most efficient ways to add livable space to your home. Without altering your existing footprint, we transform unused or outdated garages into fully functioning living spaces such as guest suites, rental units, or home offices. We handle structural upgrades, insulation, plumbing, electrical, and all required city approvals to ensure your garage ADU meets code and feels like a natural extension of your home.

Detached Backyard ADUs

For homeowners seeking more privacy or additional square footage, detached backyard ADUs provide a flexible solution. From compact studios to full-size casitas, we design and build units that complement your property’s architecture while offering beautiful, independent living spaces. With premium materials, high-end finishes, and thoughtful layout planning, your ADU becomes an inviting space for guests, family members, or long-term rental income.

ADUs for Family, Income, and Lifestyle

An ADU can serve many purposes — a private home for aging parents, a rental unit to generate passive income, a luxurious guest retreat, or a dedicated space for work and creativity. Whatever your goals, our team ensures your ADU is durable, efficient, and beautifully built to support your lifestyle long into the future.

Expert Permitting & Compliance in San Diego

San Diego’s ADU regulations offer incredible benefits, but navigating them can be complex. We manage zoning reviews, site planning, permit submittals, and code compliance to ensure your project moves smoothly and stays on schedule.
