Who builds ADUs in Kings Beach, California?
ADU Builder is a Sacramento-based design-build contractor that designs, permits and constructs accessory dwelling units (ADUs) in Kings Beach and across Placer County, serving homeowners within roughly 200 miles of Sacramento. The company handles the full project under one contract: architectural drawings, structural engineering, Title 24 energy compliance, permit submittal and corrections, and construction through final inspection. It builds detached backyard ADUs, garage conversions and junior ADUs (up to 500 sq ft inside an existing home), most commonly between 400 and 1,200 sq ft. California law allows ADUs on single-family lots statewide, with ministerial (non-discretionary) review of compliant applications. Site visits and written estimates are free, with no obligation. Contact: (916) 432-0333 or [email protected].

Why Kings Beach homeowners are building ADUs right now
Building around Kings Beach means designing for snow load, a short construction season and mountain-specific standards – and in much of the area, defensible space and ignition-resistant construction requirements as well. Projects here need to be scheduled around weather, not wished through it. The upside is a market starved for quality small units.
What your lot has going for it
- Designed for real snow loads and mountain conditions
- Construction sequenced around a short building season
- Defensible space and fire-resistant construction where required
- Scarce supply of quality small units in the area

The math you have already done in your head
If you are reading this page, you have probably stood at the kitchen window, looked at that yard, and run the numbers at least once. Here is what the numbers are trying to tell you.
The expensive part is already paid for
Anyone else who wants rental income has to buy the land first. You do not. You are only paying for the building – the dirt under it has been yours for years.
Mom stays 30 steps away, not 30 minutes
Care facilities cost more than most mortgages, and nobody is happy there. A ground-floor unit with a walk-in shower keeps family close while everyone keeps their own front door.
Permitted, inspected, on the record
A legal ADU adds a documented second dwelling to your parcel. An unpermitted conversion does the opposite – it becomes the thing your buyer’s inspector finds.
Rent it. House family. Change your mind later.
Tenant this year, your kid next year, your office after that. Once it is built and permitted, nobody’s permission is needed to change what it does.
The yard already has a bill. Give it a job.
Water, mowing, taxes – it is the only part of your property that costs money every month and earns none back. That is a choice, not a fact of life.
One contract. One phone number.
When the designer, the permit runner and the builder are the same company, there is nobody to point fingers at. Something wrong? You call one number and it is our problem.
ADU options for Kings Beach properties
Detached unit, garage conversion, or a junior ADU inside the house – the right answer depends on your lot, not on what is easiest for us to sell. Here is what we build in Kings Beach.
Detached ADU
A brand-new standalone unit in the backyard – the highest rent and the strongest resale.

ADU rules that apply in Kings Beach
California has spent the last several years stripping away the local rules that used to make ADUs almost impossible. The statewide framework now sets a floor that cities and counties cannot go below – and it is why so many Kings Beach homeowners can build today when they could not a few years ago.
- ADUs are allowed on single-family lots statewide – local agencies cannot ban them outright
- Ministerial approval – a compliant ADU application is reviewed without a discretionary hearing, so there is no neighbour veto
- Owner-occupancy cannot be required for standard ADUs under current state law
- Parking replacement is limited – in many situations cities cannot force you to replace a garage parking space you convert
- Junior ADUs up to 500 sq ft can be created inside the existing house, and many lots can have both a JADU and an ADU
- HOAs cannot flatly prohibit ADUs on single-family lots, though reasonable design standards can still apply
Your project is reviewed by Placer County planning and building. That is where the local part comes in: setbacks, height, impact fees, utility connections and design standards still vary, and they are what decides whether your permit moves or stalls. We confirm exactly what applies to your address before design starts. See how we handle permits →
This is a plain-English summary of statewide law, not legal advice. Requirements change and local rules vary – we verify the current rules for your specific parcel.

How your Kings Beach build works
We come out – free
We walk your lot, tell you what will actually fit, and give you real numbers. Costs you nothing and there is no pitch at the end.
Design & engineering
Architectural drawings, structural engineering and Title 24 energy compliance – built to clear plan check the first time.
Permits handled
We prepare the submittal, file it, and work every correction until the permit is in hand. You do not sit in a planning queue.
Built and signed off
One crew, one schedule, one point of contact – through final inspection and keys in your hand.
Read this before you talk to any builder – including us
You have heard the stories. The deposit that vanished. The price that grew every time a wall opened up. The guy who stopped answering his phone in month three. That is the reason most people never make the call – and it is exactly why we work the way we do.
The visit costs you nothing
We come to your Kings Beach property, measure, look at utilities and access, and tell you what is realistic. No fee, no deposit, no obligation to do anything afterwards.
We will tell you if it does not work
If your lot, your septic or your budget will not support an ADU, we say so at the site visit – to your face, not in a voicemail. We would rather lose the job than take your money for a project that should not happen.
You get real numbers, not a range
After we have seen the property you get an actual written scope and price – not a per-square-foot guess that quietly grows once construction starts.

Kings Beach ADU questions, answered straight
Does the short building season delay everything?
It has to be planned for. We sequence design and permitting through the off-season so construction starts as early in the window as possible. Anyone promising a mountain build on a valley timeline is guessing.
Are there extra requirements up here?
Yes – snow load engineering, and in many areas defensible space and ignition-resistant materials. We design to the standard that applies to your parcel from the beginning rather than meeting it in plan check.
Do you actually build in Kings Beach?
Yes. Kings Beach is about 100 miles northeast of Sacramento and it is inside our regular service area – we build up to roughly 200 miles out from our Sacramento base. Permits go through Placer County planning and building. Call (916) 432-0333 and we will book a free site visit.
Picture the first of the month, one year from now
Version one: rent lands in your account, and the yard finally earns its keep. Version two: same lawn, same water bill, nothing changed. The only difference between them is one free site visit – and you already know which version you want.
