Close enough for dinner. Far enough for privacy.
A permitted ADU for a parent or an adult child, whether it's a backyard build, a garage conversion, or new construction. KRN designs it, permits it and builds it on one fixed price.

Close by, without living on top of each other.
The worry is never the distance. It's whether everyone still gets to live their own life. A KRN ADU is built to answer the three things families care about most.
Privacy
Own front door, own kitchen, own bath, on their own schedule. Most units stand fully detached; when the ADU is attached to the house, we still design in a private entrance and separate living space.
Independence
Whether it's for an aging parent or a young adult starting out, they keep their own routine on their own terms. We can build in zero-step entry, a walk-in shower and grab-bar blocking for aging in place, or leave those out for a starter home that just needs its own front door.
Quality
Built like a real house, not a shed: 9-foot ceilings, real appliances, heating and cooling, its own address, permitted and inspected by the city.
One address. Two front doors.

Three ADU packages. One crew, one permit set.
Every package is the same permitted, inspected ADU. The tiers change what goes inside. Pick one and we price it on the visit.

“The workers were on time. They left at the end of the day and I never even knew that they were here. Everything was always so cleaned up and so well organized. I was constantly kept in the loop as to when people would arrive and what the next step was. I waited 10 years to have the work done because I didn't want to deal with the problems you hear about with contractors. I had none of those problems.”— William, Glendale · video testimonial
“The workers come before 7 in the morning, every morning. What amazed me was when they leave, the place is so clean. Efficiency and professionalism, combined with good work. I can recommend these guys to anyone in a heartbeat.”— Rustum, Eagle Rock · video testimonial
What families ask before building an ADU
“Will Mom feel like she's living in a shed?”
No. Full kitchen, full bath, 9-foot ceilings, its own address. Most parents say it's the nicest place they've lived.
“Are we going to lose the whole backyard?”
Not at all. We design the ADU for the best of both worlds: a beautiful backyard and full privacy, all within city code and regulations.
“How do families pay for it?”
Financing or paying out of pocket, whichever fits. We'll connect you with our third-party lending partners to find the best option for your needs.
“Will our property taxes explode?”
Only the new ADU or converted space gets reassessed, at its added value. Your home's existing assessed value stays protected. We confirm the estimate with you before any permit is submitted, based on the LA County Assessor's Office.
“What if Mom doesn't need it someday?”
Then it's a guest house, an office, a home for a kid, or a rental. A standard rent for a one-bedroom ADU is listed between $1,950–2,650 a month.
Sunday dinner. Everyone goes home to their own door.
We'll visit your lot for free and leave you with an ADU sketch and a real budget. If it doesn't make sense for your family, we'll tell you.
