Rental Income
San Diego's rental market is among the strongest in the country. A well-designed ADU can generate meaningful monthly income or short-term rental revenue, often offsetting a significant share of your mortgage.

San Diego is one of the best places in the country to add an accessory dwelling unit. Noble designs and builds detached ADUs, garage conversions, and junior ADUs that earn income, house family, and grow your property's value.
An accessory dwelling unit is a fully independent home — kitchen, bath, and living space — built on the same lot as your house. Thanks to California's state ADU laws and San Diego's progressive local programs, building one has never been more achievable.
Whether you are picturing rental income, a private space for aging parents, a returning college grad, or a dedicated home office and guest suite, we design ADUs that fit your lot, your budget, and the way your family is changing.
Why build an ADU
San Diego's rental market is among the strongest in the country. A well-designed ADU can generate meaningful monthly income or short-term rental revenue, often offsetting a significant share of your mortgage.
Keep family close while preserving everyone's independence — a private, dignified space for aging parents, adult children, or visiting family, just steps from the main house.
Adding legal, permitted square footage and a second income-producing dwelling is one of the most reliable ways to increase a San Diego property's long-term value and appeal.
Today a home office, tomorrow a guest suite, later a rental. An ADU is one of the most adaptable investments you can make in your property as your needs evolve.
What we handle
We start by studying your lot, setbacks, and goals, then design an ADU that maximizes usable space and natural light while complementing your existing home — delivered with photoreal 3D renderings before we build.
We navigate San Diego's permitting process, including the City's pre-approved ADU plan options where they fit, and design to current state ADU standards and Title 24 energy compliance so your project approves smoothly.
Water, sewer, electrical, and HVAC are planned and connected properly — whether your ADU shares services with the main home or runs independently — so it functions as a true, comfortable residence.
One design-build team handles everything through final inspection: foundation, framing, finishes, and fixtures. You get a single point of contact and a move-in-ready ADU, not a coordination project.
Recent work
Independent, light-filled homes that feel anything but secondary.
Smart design makes a small footprint live large — full kitchens, comfortable baths, and open living spaces with abundant natural light. Our detached ADUs are designed to feel like a true home, not an afterthought.
We design exteriors, rooflines, and finishes that echo your main home and respect your yard and neighbors. The result reads as an intentional part of the property — adding value and curb appeal, not subtracting from it.
Homeowners love us
“We built a detached ADU for my parents and it has completely changed our lives. Noble guided us through the permits, the design, all of it. My mom has her own beautiful home and we are right next door.”
“Our garage conversion ADU rents out within days every time and the income covers a huge chunk of our mortgage. The build quality is excellent and it was genuinely turnkey from design to keys.”
“I was overwhelmed by all the ADU rules until I called Noble. They knew the San Diego programs cold and designed a JADU that fit our home perfectly. Clear timeline, no surprises, and it passed inspection first try.”
Common questions
ADU cost depends heavily on size, type, finishes, and site conditions — a garage conversion or junior ADU sits at the lower end, while a fully custom detached unit costs more. Rather than quote a generic range, we walk your property and goals and provide a detailed, transparent estimate at no cost, so the number reflects your actual project.
Timelines vary with design complexity, permitting, and ADU type. Once design is finalized and permits are issued, construction generally takes a few months. We build a realistic schedule during planning and keep you updated throughout, so you always know where your project stands.
A detached ADU is a standalone home elsewhere on your lot. An attached ADU is connected to or converted within your existing home, including garage conversions. A JADU (junior ADU) is a smaller unit created within the existing footprint of the house. Each has different size, parking, and code considerations — we will recommend the best fit for your lot, budget, and goals.
Yes. As a design-build remodeler, we manage the entire process — design, San Diego permitting, Title 24 energy compliance, and inspections — under one roof. ADU rules at the state and local level evolve, so we confirm the current requirements for your specific property as part of your project rather than relying on assumptions.
