An accessory dwelling unit conversion turns space you already have, usually a garage or a detached structure, into a separate legal unit. The construction work at the center of it is a kitchen and a bathroom, which is exactly what we do, but the project does not begin there. It begins with what the parcel allows and which department reviews it. In Yuba City that is the Development Services Department, and the city's Permit Planner tool will give you requirement and fee estimates on a specific address before an application goes in. State ADU law and the local implementation both apply, and both change often enough that anything you read from a few years ago is worth re-checking. The heaviest physical item in most conversions is the bathroom, because a garage generally has no waste line anywhere near it. Getting a drain to the existing sewer connection at the right slope is what determines whether a conversion is straightforward or expensive, and on a slab that means cutting concrete. The kitchen side is usually simpler: supply, a drain, and the electrical for appliances. We look at where the existing sewer lateral runs before quoting anything, because that single fact moves the number more than any finish decision will.
The sequence is feasibility and permit path first, then plans, then review, then build. Rough-in inspections for plumbing and electrical happen before walls close, and those dates set the schedule rather than our crew's availability. You receive the scope broken into the permit-driven work and the finish work separately, so it is clear which parts of the timeline we control and which parts belong to the review counter. Where a conversion turns out not to be feasible on a given parcel, we would rather establish that during feasibility than after you have paid for plans.

Establishes what the parcel allows and which counter reviews the application.
Adds the cooking, sink and appliance provisions a unit needs to be legal.
Runs new supply and waste lines, which is the heaviest item in most conversions.
Proudly serving Yuba City, Marysville, Live Oak, Wheatland, Plumas Lake and Gridley for years.
Ten services, grouped the way the work actually gets bid. Bathroom projects run from a tile replacement to a walk-in shower or a tub conversion. Kitchen projects run from countertops and cabinet refacing through a full remodel. ADU conversions sit between the two, because an added unit needs both a kitchen and a bath.

The permit path changes between these towns and it changes the schedule. Marysville and Live Oak run their own counters. Wheatland and Plumas Lake both go through Yuba County. Gridley splits it, with zoning at the city and building inspection at Butte County. We track which counter a job belongs to before demo.
Frequently Asked Questions
Kitchen and Bathroom Remodeling can be complex, and we’re here to provide answers to common questions. Here are some frequently asked questions from our clients.
There is no single price for a Yuba City bathroom remodel. Cost follows whether the toilet, tub and vanity stay where they are, whether the supply and waste lines behind the wall get replaced, and what the permit scope turns out to be once plans are reviewed. A tile and fixture refresh in an existing footprint and a remodel that relocates the drain are not comparable jobs. We price after a walkthrough, not before one.
Most bathroom remodels do, and the answer depends on the scope rather than the room. Work inside the city limits goes through the City of Yuba City Development Services Department, and the city runs a Permit Planner tool that estimates requirements and fees before you apply. Plumbing relocations, electrical changes and anything structural will pull a permit and an inspection sequence. We file the application and schedule the inspections as part of the job.
Schedule follows the permit and inspection sequence, whether fixtures move, and lead times on tile, glass and any custom vanity. A single-scope refresh that keeps every fixture in place moves quickly. A remodel that relocates the drain adds an open-floor inspection before anything gets closed up, and that inspection date is what sets the finish date.
Kitchen cost is driven by three decisions: whether the cabinets are refaced or replaced, whether the layout changes, and what the countertop material is. Refacing existing boxes and installing new countertops is a different order of project from moving the sink and the range. We walk the kitchen, confirm what the cabinet boxes are actually made of, and price the options separately so you can see what each decision costs.
A full remodel means demo to the studs and subfloor, then rebuilding: waterproofing, any plumbing and electrical changes, tile, the shower or tub, vanity, fixtures and finish work. It also includes the permit application and the inspections that come with opening a wall. What varies most is whether the supply and waste lines get replaced while they are exposed, which is usually the right call in older Yuba City homes and worth deciding before demo rather than during it.
Ask who is actually doing the work and where they are based, because a good share of the companies advertising in Yuba City run their crews out of the Sacramento area. Ask for a written scope after a site visit rather than a number over the phone. Ask which counter the permit goes to, since a contractor who cannot answer that for your address has not done the work here.
The largest variable is the bathroom drain. A garage with the sewer lateral running nearby is a different project from one where the waste line has to cross the whole slab at the correct slope. Plan review requirements and whether the structure needs upgrading to habitable standards are the other two drivers. We establish those three things before putting a number on the work.
Garage conversions are one of the more common ADU paths, but what your specific parcel allows depends on zoning, setbacks and the structure itself. The City of Yuba City Development Services Department is the authority on that, and the Permit Planner tool gives an address-specific starting answer. We check feasibility before any design work begins.
A unit needs cooking, sink and food storage provisions to be a dwelling rather than a converted room, and the specifics come from the applicable code and local requirements. That is why an ADU conversion is a kitchen and bathroom project at its core. We build both to what the reviewing department requires rather than to a general standard.
Construction is usually the shorter half. Plan preparation and review come first, and the rough-in inspections during the build set the pace of everything after. We give you the construction timeline and the review timeline as separate figures, because combining them into one number hides which part is actually moving.

Our house in Plumas Lake West was built in 2006 and the builder tub had never been touched. They converted it to a walk-in shower without moving the drain, which kept the cost where they said it would land. The whole thing was done in the window they gave us.

We have a pre-1960 Craftsman near Downtown Marysville and two other companies quoted it over the phone without looking. These guys came out, found the old waste line was the real problem, and put it in the written scope before we signed anything. The tile work in the finished bathroom is excellent.

They refaced our kitchen cabinets and replaced the countertops instead of talking us into a full remodel we did not need. Our place is off Washington Avenue in Gridley, so the permit side went through Butte County, and they handled all of that scheduling. Honest about what could wait.
