The Accessory Dwelling Unit

An accessory dwelling unit is a compact and self-contained living space that is typically situated on the same property as a primary residence. You might know them by another name: “casitas,” “granny flats,” “in-law suites,” or “backyard cottages.” They are a versatile and useful housing option, recently popular due to their potential to address multiple challenges in the housing market.

They come in various forms, including converted garages, basement apartments, or standalone structures. They can be attached to the main residence, as in a basement suite, or they can be completely independent. They also must have all the amenities one expects from a home: kitchen, washroom, and independent water and electrical systems. Often, they have separate entrances and parking accommodations. In California, an ADU can be as large as 1200 square feet. Custom ADUs can be built closely to the customer’s specifications, but we also offer beautiful pre-approved ADUs.

For those with smaller properties, another option is the Junior Accessory Dwelling Unit (JADU), which can be as big as 500 square feet and can share systems with the main dwelling. For those with limited space and funds, this is an attractive option to expand one’s properties.

Why Have One?

What is an ADU used for? Almost whatever you please. They are flexible structures, useful in many ways:

Multigenerational Living

They are convenient for elderly parents or grown children, providing both privacy and proximity.

Guest Houses

For those with frequent, intermittent visitors, ADUs function wonderfully as guest houses. You’ll preserve your privacy, and your visitors will be glad to not have to sleep on the fold-out couch.

Home Office or Studio

An ADU can serve as the perfect home office, artist studio, or hobby space, keeping work and living areas separate.

Rental Income Potential

Many homeowners build ADUs to offer for rent. Earning rental income is a great way to supplement one’s income or defray mortgage costs, and a new generation of homeowner–landlords are springing up in Southern California, offering much-needed desirable living spaces to tenants.

Increased Property Value

No matter your reason for having one, and ADU is great for your property value. Two homes on one property is a great attraction for buyers.

Additionally, ADUs offer a creative solution to urban density by utilizing existing land more efficiently and increasing the housing stock without altering the neighborhood’s character. These dwelling units contribute to sustainable living, as they often repurpose existing structures, minimizing the need for new construction and reducing the strain on resources.

In summary, accessory dwelling units are a flexible housing solution that supports multigenerational living, addresses housing shortages, and promotes sustainable urban development. As cities adapt to changing demographics and housing needs, ADUs are emerging as a practical and innovative answer to various challenges in today’s housing landscape.

Types of ADU

ADUs are built in several different ways:


The domicile is isolated from the main residence, offering maximum privacy.


The living space is adjacent to the main structure, either laterally or on a different floor. There may be a shared entrance and parking, but it must have separate rooms and systems.


Transform an existing structure into a beautiful home. Garage conversions are especially popular in California.

In our years of experience, we have designed floor plans, MEP designs, and interior finishes for all kinds of ADUs. Tell us what you need and what your property needs, and we’re sure to create something that will suit you perfectly.
