The Designer Guide
Your backyard is worth more than you think.
An accessory dwelling unit adds rental income, lasting value, and room for family — one licensed team designs, permits, and builds it. Learn how it works, then design yours in minutes.
How the designer works
Design your ADU in minutes — and watch the price update live.
Our interactive designer walks you through it one decision at a time, with a live 3D model of your ADU and a running estimate at every step.
Pick your floor plan
From a 400 sq ft studio to a 1,000 sq ft two-bedroom — start with the layout that fits your lot and your goals.
Choose your style
Three architectural styles, rendered as a live 3D model of your ADU that updates with every choice you make.
Select every finish
Cabinets, counters, flooring, siding, and more — real products we install, in Standard, Premium, and Luxury tiers.
Get your estimate
A transparent line-item estimate that updates live as you design — free, with no obligation and no surprises.
One product, three tiers — every option in the designer is a real product we install, photographed from our own builds.
“We designed the whole thing online on a Sunday night — picked the floor plan, the siding, the counters — and the estimate updated as we clicked. When their designer called, we were already 90% decided.”
Why build an ADU
One backyard. Three ways to win.
An ADU is the rare investment you can live next to — rental income, property value, and space for family, all on land you already own.
Monthly rental income
Southern California ADUs rent for roughly $2.90–$3.35 per sq ft — a 600 sq ft one-bedroom can bring in about $1,700–$2,000 every month, year after year.
Lasting property value
A permitted, new-construction ADU adds real square footage — and real equity — to your property, with potential tax advantages for rental use.
Room for the people you love
Aging parents, adult kids, guests, or a private office — a backyard home gives your family independence without distance.
Plan around $450–$550 / sq ft, all-in — design, engineering, permits, construction, and standard finishes. Units under 750 sq ft are exempt from city impact fees by state law.
The transformation
An underused backyard becomes a second home.
Real All Inclusive ADU projects — the same lot, before and after.
A wide, underused backyard becomes a modern one-bedroom rental.
Same lot, new income — a detached ADU tucked along the side yard.
ADU 101 — California law
The state already said yes.
California law guarantees your right to build — six rules every homeowner should know.
Allowed on nearly every lot
ADUs are legal in every residential zone in California — with no minimum lot size. If you own a home, you can almost certainly build one.
Guaranteed square footage
Every city must approve at least 850 sq ft (studio / 1-bed) or 1,000 sq ft (2-bed+). Many allow detached ADUs up to 1,200 sq ft.
4-foot setbacks
Your ADU can sit just 4 feet from side and rear property lines, up to 16–18 feet tall — most backyards qualify.
Your garage counts
Legally built garages and accessory structures can be converted — or demolished and rebuilt as an ADU in the same footprint.
No one can veto it
HOAs can’t prohibit an ADU, neighbors’ sign-off isn’t required, and you don’t have to live on the property to rent it out (30-day+ rentals).
Usually no extra parking
Conversions need no new parking, and new ADUs near transit are exempt too. When one space is required, a tandem driveway spot counts.
Current as of 2026 state ADU law. Every city adds its own details — we confirm exactly what your lot allows, free, before you commit to anything.

One team, one contract, one timeline — from the first conversation to keys in hand.
Free consultation
On-site assessment of your lot, goals, and budget — and a fixed-price quote.

The finishes you’ll design — already built.
Every kitchen, bath, and detail in the designer comes from real All Inclusive ADU projects like these.
Financing
You may not need to pay out of pocket.
We work with preferred lenders who specialize in ADU and renovation financing. Many homeowners get approved using their existing home equity — we’ll connect you and help you compare options as part of your free consultation.
“The fixed price is real. The number they gave me at the consultation is the number I paid at the end — and the rent covers the loan payment with room to spare.”
