What is an ADU Kitchen?

An ADU kitchen is a functional kitchen that maximizes space usage, allows for easy mobility, and is designed to be energy-efficient. An ADU kitchen is an essential piece of any ADU project, even the prefab ADU units.

It is a compact yet fully functioning kitchen perfect for meal prep, food storage, and enjoying cozy dinners. The kitchen in an ADU is usually in one living space with an eating area and living room space.

It is usually attached to a house or garage or stands as an independent unit and may include its living area and separate entrance.

Does an ADU have to have a Kitchen?

To answer this, you have to know the laws in your area. Most ADUs will be rentals, so having a kitchen or a kitchenette is likely necessary. Think of what type of tenant you are trying to attract and what the rental income on the property will be.

If your ADU will not be a rental unit and is instead for a guest house, elderly parents, or other family members, you may want to still design around the idea of it being a rental in the event you sell in the future.

You could make accommodations now that serve the immediate need but can also be adjusted for a different purpose when the time arises.

This will help determine what you must put into the kitchen to satisfy future tenants. Remember, kitchens and bathrooms sell – and the same for rentals.

What are the minimum ADU Kitchen requirements?

Understanding ADU kitchen requirements goes a long way in ensuring compliance with state and local laws. These requirements can differ depending on where you live. So, it’s always a good idea to check with your local building codes and regulations to know the specific requirements in your area.

In California, an “Efficiency kitchen” means a kitchen that includes each of the following: (a) a cooking facility with appliances; (b) a food preparation counter or counters that total at least fifteen (15) square feet in area; and (c) food storage cabinets that total at least thirty (30) square feet of shelf space. [1]

If you break down the definition for the food prep space, you need a 7’6″ countertop (bottom cabinets are usually 24 inches deep).

This could be a 4″ by 3’6″ L shape, which is not much space.

It is more of a mini kitchen that won’t fit a ton of stuff, but with the proper organization, you could rival a spacious kitchen.

Designing a Functional ADU Kitchen

Designing a functional and welcoming space is easy. There are some basics you must have in your ADU kitchen, and depending on who will be staying in the unit, you could sprinkle in a few nice amenities in creative ways.

Here are a few questions to get you thinking about design:

  • Have you heard of the work triangle?

  • What about the appliances that can make your compact ADU kitchen as functional as a full-size one?

  • How do you get the most natural light?

  • How creative can you get on a budget to maximize functional storage?

  • How do you plan a layout that best uses your space?

It’s time to dig deeper into these questions.

Ergonomically Designed Work Triangle

A kitchen work triangle is integral to efficient kitchen design, even in a smaller kitchen. It’s a guideline for the placement of the three primary kitchen tasks:

  • cooking (stove)

  • cleaning (sink)

  • food storage (refrigerator)

These three points form a virtual functional triangular work area in the layout of the kitchen, optimizing movement and reducing the need for unnecessary steps. (You may have to find another way to get your steps in!)

This may not be a huge deal in a small space because you may not be as spread out, but it could be a factor when figuring out the layout of the space of larger ADUs.

Space-saving and multi-functional Appliances

Reality check – not all ADU kitchens in accessory dwelling units are spacious. But does that mean you have to compromise on functionality? Nope!

Three words – Creative Functional Storage – and the right appliances. Many small appliances are designed to fit in smaller spaces.

A small induction cooktop with two burners may just be what your space needs instead of one of the four burner stoves. There are built-in ones and portable ones.

A convection bake microwave with an air fryer feature can replace an oven, microwave, and air fryer. This could save you a ton of space.

Single basin sinks with a built-in cutting board can save counter space. Do most people need two sinks, even in a standard kitchen?

A narrower refrigerator instead of a full refrigerator may be an option if you are short on linear footage.

A small stand-up freezer could offer an as-needed serving area or counter space.

If a dishwasher is necessary, you could opt for a portable one on a counter or shelf.

How about a griddle, coffee maker, and toaster all in one? This could help you pack some functions into one device.

A nice blender serving as a food chopper or smoothie maker would be an excellent addition to a kitchen space.

Layout Options

The layout of your ADU kitchen plays a significant role in maximizing space and ensuring functionality.

Kitchen layouts w names

Here are some popular kitchen layout ideas to consider:

  1. L-shaped kitchen: This layout gives ample room for upper and lower cabinets.

  2. Galley-style kitchen: This layout features two parallel walls with a walkway in between, maximizing efficiency in a small space.

  3. One-wall kitchen: This layout saves space and creates an open floor plan.

  4. U-shaped kitchen: This layout takes the L-shape and give a bit more storage and prep space and is usually considered the most efficient layout.
Interior Design Tip

A great example of a layout hack is how you can affordably take an L-shaped kitchen and add some 6-9″ shelving on the opposite wall to create the functionality of a U-shaped kitchen.

Cost-Effective Choices for ADU Kitchens

Building your dream kitchen in your ADU doesn’t necessarily require a hefty budget.

Believe it or not, plenty of cost-effective choices can help you design a welcoming and full kitchen without stretching your budget or having a larger kitchen space.

Consider the following design ideas to create a beautiful and functional kitchen without overspending:

  • Choose energy-efficiency appliances

  • A large stainless steel backsplash could create magnetic storage space.

  • Opt for budget-friendly materials yet still have an upscale look, such as using remnants for a granite countertop.

  • Get creative with countertops. Utilizing epoxy can be a cost-effective way to create a beautiful countertop.

  • Pay attention to the smaller details and find cost-effective options. Things like cabinet knobs can make a big impact on style and design.

  • Many flooring vendors have small lots of discounted flooring.

  • Some opt to stain and seal the concrete to save money.

  • Small kitchens may only need a few cabinets that could be found at discount stores or a marketplace.

  • Open Shelving is usually cheaper than upper cabinets.

  • Repurpose items for storage, such as a dresser or side table.

  • A multi-functional rolling kitchen island can give you additional storage and counter space and create an eat-in kitchen when needed. There are really affordable options.

  • Baskets are an excellent way to create a cohesive look on an open shelf

Storage Solutions for Small Kitchens

In ADU kitchens, maximizing square footage is crucial. And when it comes to storage, it’s all about making the most of your space. Here are some storage solutions and ideas for small kitchens:

  • Floating shelves instead of extra upper cabinets

  • Deep drawers

  • Pull-outs

  • Wall-mounted racks

  • Utilizing shelving suspended from the ceiling

  • Use 24-inch-tall cabinets that go to the ceilings.

  • Over-the-door storage racks

Not only do these options offer efficient storage solutions, but they also add a touch of style to your kitchen.

They also give the space a modern feel and allow you to display your favorite dishes, beloved coffee mugs, or your collection of spice jars.

Large Windows and Skylights

Natural light can be your kitchen’s best friend. Large windows and skylights can bring in significant natural light, transforming your kitchen into a bright and inviting space.
