Home›ADUs
A second home, right in your backyard.
Detached ADUs, garage conversions, and junior units for San Diego properties — designed and built as one seamless project, from first sketch to front-door key.
San Diego ADUs
A complete home, in compact form.
An accessory dwelling unit is a fully independent home — kitchen, bath, and living space — on the same lot as your house. San Diego has long been one of the friendlier places in California to build one, and we help you make the most of it, navigating the current city requirements as part of the design.
Smart design makes a small footprint live large: a real kitchen, a comfortable bath, and light-filled living space that feels like a true home, never an afterthought.
- Detached ADUs, attached units, and garage conversions
- Junior ADUs (JADUs) within your existing footprint
- Guidance through current city and state requirements
- Exteriors designed to complement the main home
Why build an ADU
One small build, several big returns.
Few projects change what a property can do for a family the way an ADU does.
Rental Potential
Strong rental demand across San Diego makes a well-designed ADU a meaningful source of monthly income — a small building that keeps working for you.
Multigenerational Living
Keep family close while preserving everyone’s independence — a private, dignified space for parents, adult children, or long-stay guests.
Long-Term Value
Adding permitted, livable square footage — and a second dwelling — is one of the most reliable ways to grow what your property can do.
Flexible Space
Today a home office, tomorrow a guest suite, later a rental. Few investments adapt to a changing household the way an ADU does.
From sketch to keys
One team handles everything.
An ADU is a whole house in miniature — design, approvals, utilities, and construction. We carry all of it as a single, organized project.
- 01
Site & Design
We study your lot, setbacks, and goals, then design an ADU that maximizes usable space and natural light while complementing the main home.
- 02
Plans & Approvals
ADU requirements evolve, so we help you navigate the current city and state rules for your specific property — and prepare plans that can move forward smoothly.
- 03
Utilities & Systems
Water, sewer, electrical, and heating are planned properly from the start — whether the unit shares services with the main house or runs independently.
- 04
Turnkey Build
One team carries the project through construction and final walkthrough — foundation, framing, finishes, and fixtures, with a single point of contact throughout.

Good to know
ADU questions, answered.
It depends on the type and the site. A garage conversion or junior ADU sits at the lower end; a fully custom detached unit is a larger investment. Site conditions — utilities, access, grading — matter as much as square footage, so we scope every project individually. The estimate is free and based on your actual property, not a generic number.
A detached ADU is a standalone home elsewhere on your lot. An attached ADU is connected to or converted within your existing home — garage conversions included. A JADU (junior ADU) is a smaller unit created within the existing footprint of the house. Each comes with different size and code considerations, and we’ll recommend the best fit for your lot and goals.
Yes. ADU rules at the state and city level continue to evolve, so we never design from assumptions. As part of the design phase we help you navigate the current San Diego requirements for your specific lot — setbacks, utilities, and approvals — so the plan that gets drawn is one that can get built.
Design and approvals typically take a few months before construction begins, and the build itself runs several more depending on the type and complexity of the unit. We map out a realistic schedule during planning and keep you updated at every step.
Yes — and we think it should. We design exteriors, rooflines, and finishes that echo the main home and respect the yard around it, so the ADU reads as an intentional part of the property, adding to curb appeal rather than competing with it.
