ADUs in California
What is an ADU?
An ADU — accessory dwelling unit — is a second, independent home on the same lot as a single-family house. It can be a detached backyard cottage, a garage conversion, or an addition with its own entrance. In California, ADUs are fully permitted residential units with their own kitchen, bath and living space.
We build ADUs because they use land you already own, add real housing without a full custom-home budget, and create options families actually use — aging parents nearby, a rental that helps with the mortgage, or a private office that is not a spare bedroom.
Use the backyard you already pay for
An ADU turns unused space into livable square footage without buying a new lot or moving.
Rental income and flexibility
Many homeowners use an ADU as a long-term rental or family guest space. Local rules vary; we help you understand what is allowed on your parcel before you commit to plans.
Multigenerational living
Keep family close with a separate front door, kitchen and bath — privacy for everyone on one property.
California is built for ADUs
State law requires cities to allow ADUs on most residential lots, with clear standards for size, setbacks and parking. That makes permitting predictable compared to many other project types.
Lower fees on the horizon — and clearer rules already in place
Governor Gavin Newsom signed SB 1117 in September 2026. It takes effect January 1, 2027. The law fixes a fee cliff that punished slightly larger ADUs: instead of charging full local impact fees on every square foot once an ADU passes 750 square feet of interior living space, cities must charge those fees only on the area above 750 square feet — for up to two ADUs on a lot. That can save thousands on a family-sized unit.
SB 543 and AB 1154, already in effect since January 2026, tightened how ADU applications are processed and clarified that size limits apply to interior livable space — so you are not penalized for wall thickness or covered porches counted the wrong way.
Impact fees are only part of the total cost. Permit processing, utility connections and school fees may still apply depending on your city and project. We itemize every line in your proposal so nothing is a surprise. Ask us how this applies to your lot.
Who we are
A builder who answers the phone.
Most complaints about contractors aren't about craftsmanship — they're about silence. Calls that aren't returned, costs that appear without explanation, and a job that sits at ninety-five percent for two months.
We built Artistek to work the other way around. You get a written scope before anything starts, a call the same day we find a problem, and a finished project that gets signed off together rather than quietly abandoned.
We work throughout Roseville, Rocklin, Lincoln and the surrounding Placer County, California, on tiny homes, ADUs, additions and custom playhouses — projects sized for backyards and existing homes, not full estate builds.
What we build
Services
Four focused scopes — tiny homes, ADUs, additions and custom backyard structures — all run by the same team and the same standard. If you're not sure which one fits, describe the project and we'll tell you.
ADUs
Accessory dwelling units — detached cottages, garage conversions and backyard homes with their own kitchen, bath and entrance, built to California's ADU standards.
What's includedTiny Homes
Compact, permitted dwellings — detached tiny homes, backyard studios, and small-footprint living spaces built to California code.
What's includedHome Additions
New square footage tied into the house you already have — room additions, bump-outs, and second-story expansions with structural work done right.
What's includedCustom Playhouses & Structures
One-of-a-kind playhouses, treehouse platforms, backyard forts and small custom structures — built safely for kids and built to last outdoors.
What's included
How we work
Four things we hold ourselves to.
Not slogans. These are commitments you can point at mid-project if we ever fall short of them.
Straight answers
If a change costs more, you hear it from us the day we find it — with the number attached. No surprise line items at the end of the month.
Written scope, itemized
Every estimate breaks out labor, materials and allowances so you can see exactly what you're paying for and compare it honestly against another bid.
One accountable builder
You get one point of contact who is actually on the job — not a salesperson who hands you off to a crew you've never met.
Finished means finished
We don't call a project complete until the punch list is signed off and the site is clean. The last five percent is the part most people remember.
Our process
No mystery, six steps.
Every project runs the same way, whether it's a playhouse or a tiny home. You always know what happens next and roughly how long it takes.
- 01Same week
Conversation
We talk through what you're trying to accomplish, what you'd like to spend, and when you need it done. If your budget and scope don't line up, we say so now rather than after you've paid for drawings.
- 021 – 2 weeks
Walkthrough & measurements
We come to the property, take measurements, look at the existing conditions, and photograph everything relevant. This is where we find the problems that change the number.
- 031 – 2 weeks
Itemized proposal
You get a written proposal broken out by trade, with allowances called out separately so you can see where your selections will move the total. We walk through it with you line by line.
Steps four through six cover permits, the build itself, and the joint walkthrough at the end.
Where we work
Local, and staying that way.
We keep our service area tight on purpose. Being twenty minutes from your job means we can be on site the morning something comes up, and it means the trades we use are people we see every week.

Common questions
The things people ask first.
If your question isn't here, call (916) 870-3264 and ask. You'll get a real answer, not a sales pitch.
An ADU (accessory dwelling unit) is a second, independent home on the same lot as your house — with its own kitchen, bathroom and entrance. California law makes ADUs feasible on most residential lots, and they are a strong fit if you want rental income, space for family, or a backyard home without buying new land. Governor Newsom signed SB 1117 in September 2026; it takes effect January 1, 2027 and reduces local impact fees on ADUs larger than 750 square feet by charging those fees only on the area above 750 square feet (for up to two ADUs on a lot). That removes a fee cliff that used to punish slightly bigger, family-sized units. Permit and utility costs still apply — we itemize them up front.
Nobody can answer that honestly over the phone in one minute, and you should be skeptical of anyone who tries. What we can do on a first call is give you a realistic range based on similar work, and tell you plainly whether your budget matches the scope you're describing. The itemized number comes after we've walked the property.
Initial consultations and site walkthroughs are free. For large or complex projects that need significant design and takeoff work before a number is possible, we'll tell you up front if there's a fee and what it covers — you'll never be billed for something you didn't agree to.
In writing, before the work happens. Older homes hide things behind the drywall, and when we find one you get a call the same day with the options and what each costs. You approve the change order first. We don't do surprise invoices.
Usually yes, with planning. We sequence structural work, tie-ins and finish so you are not cut off from the rest of the house longer than necessary. For second-story work we will be upfront about noise, dust and any rooms that need to be off limits for safety.
