ADU Kitchen & Bath Finishes in Los Angeles, CA

ADU kitchen cabinets for a compact layout

Most ADU kitchens run between about 8 and 14 feet of cabinetry. Choosing the layout and appliance sizes first lets the cabinet order follow.

Compact appliances, such as a 24-inch range, an 18- or 24-inch dishwasher and a counter-depth fridge, free up cabinet space. Stock and semi-custom lines keep the budget in line, and the small kitchen remodel page covers storage ideas that carry over to an ADU.

Garage conversion kitchen and ADU flooring on a slab

A garage conversion starts with a concrete slab that was poured to drain toward the door, so it is rarely level and may carry moisture. The builder handles leveling and any vapor barrier, and the floor you choose should suit what is underneath.

• Waterproof vinyl plank: the most common ADU flooring; tolerant of slab moisture when installed over the right underlayment, and warm underfoot. See waterproof vinyl flooring.
• Porcelain or wood-look tile: bonded directly to a prepared slab; durable and good for rentals.
• Engineered hardwood: possible over a dry, flat slab with a moisture test first; avoid solid hardwood directly on concrete.
• Carpet: an option for a bedroom in a larger unit, at a range of price levels.

Run one floor through the whole unit when possible. In a small space, a continuous floor makes the rooms read larger and avoids transitions.

Four common ADU types and what each means for finishes

• Garage conversion: a sloped slab that needs leveling, so floor thickness is settled before cabinets are ordered.
• Detached backyard unit: a new slab and new walls, so the finish list can be planned from scratch.
• Junior ADU: space carved from the main house, where finishes usually match the existing rooms.
• Unit over a garage: stairs to cover and sound between floors to manage with underlayment.

What goes into an ADU bathroom?

ADU bathrooms are usually 5 by 8 feet or smaller. A shower instead of a tub, a 24- to 30-inch vanity with a prefab top, a niche for storage and a mosaic shower floor cover most needs. Using the same floor tile or vinyl from the main room through the bathroom, where the product suits wet areas, keeps the unit visually calm. For more ideas, the small bathroom remodel page covers compact vanities and tile sizing.

Does a junior ADU kitchenette need a full kitchen?

Under California law, a junior ADU is a unit of up to 500 square feet within an existing single-family home, and it must include an efficiency kitchen with a cooking appliance, a food preparation counter and storage cabinets of reasonable size. That is less than a full kitchen, so a short run of base and wall cabinets with a prefab top and a small sink often suffices. Local rules on appliances and sinks can vary, so check the JADU requirements with LADBS in the City of LA or your own city’s planning and building department before ordering.

Building an ADU finish package with your builder

1. 1

   Start from the builder’s plans

   Bring the floor plan with kitchen and bath dimensions and appliance sizes, along with any finish allowances.

2. 2

   Pick the floor and cabinets together

   They cover the most area and set the look of the unit.

3. 3

   Choose counters, sink and backsplash

   Prefab tops suit standard runs; a slab suits a peninsula or unusual size.

4. 4

   Finish the bath

   Vanity, top, shower wall and floor tile chosen to match the kitchen palette.

5. 5

   Confirm and schedule

   Share the finish list with the builder, confirm dimensions, then order with expected arrival windows and book installation if wanted.

What changes the cost of an ADU finish package?

• Cabinet run length and height: uppers to the ceiling add boxes but save floor space.
• Counter format: a prefab top suits a straight run; a peninsula or odd size needs slab.
• Floor area and prep: continuous vinyl or tile over a leveled slab, plus any moisture control.
• Bath tile coverage: floor-to-ceiling shower walls versus tile only where water hits.
• Appliance sizes, which decide how many cabinet boxes fit around them.
