What is an ADU?

ADU stands for accessory dwelling unit. Other names include mother-in-law units, casitas, and guest houses. Each accessory dwelling is considered a secondary housing unit independent from the main single-family house, meaning you can rent them out separately. There are different types of ADUs, such as garage conversions, detached or attached ADU’s, Pre-fab ADUs, along with many others, each meant to serve different purposes.

Why Build an ADU?

Rental Income

Rent out the ADU, or move into the ADU and rent out the main house.

Ease of Financing

Use the equity in your home to build the ADU, rent it out, and make additional income.

Multi-Generational Family Living

Allow family members to stay in the ADU, keeping them close, while giving them independence.

The Benefits of having an ADU

An ADU adds value to your property. You are essentially adding square footage to your residence at a cost that is less than the value you’ll gain. New laws have recently passed in California allowing homeowners to build an ADU and a Junior ADU on their property. This means that you could rent out the main residence or ADU to one family and the Junior ADU to someone looking for a studio apartment. You could potentially have multiple rental incomes from one property! Whether you plan to live in the ADU or not, the potential for rental income makes having an ADU, or two, worth it.

An ADU adds square footage! You are essentially building a second home onto an existing property, creating room for elderly parents, adult children or extended relatives. Many of our ADUs are built with universal design in mind to provide easy access for the elderly and those with disabilities. Adding an ADU also benefits remote workers who need an office or meeting space at home.

Why Choose Superior ADUs - ADU Builders Orange County

Superior ADUs is here to help anyone who desires to have an ADU built on their property.  We have pre-designed a series of ADU Models in a variety of sizes, floor plan configurations, and architectural styles. The architectural plans and engineering for our ADU Models are already complete, which saves you time and money. We also offer three different pre-designed finish material packages – transitional, modern, or contemporary. You simply choose what you want, and we take care of the rest.

You can also choose to have Superior ADUs design, develop, and build a Custom ADU on your property. The benefit of this option is the flexibility you have with the placement, size, orientation, and layout of the Accessory Dwelling Unit. A Custom ADU also allows homeowners the option to attach the ADU onto the main dwelling or garage. However, the Custom ADU process will take longer, since your ADU will be custom-designed from scratch to fit you, your needs and your property.

All of our ADUs are built from the ground up on your property, also know “stick-builds”. We do NOT offer pre-fabricated ADUs, as they tend to be challenging to pass through cities in our area, as well as costly to transport. Stick-build ADUs allow us the freedom to alter the design, if needed, in order to meet city standards, HOA regulations, site parameters, and client needs.

Frequently Asked Questions

Generally, you can have two ADUs – one primary and one junior ADU (JADU) – on a single-family residential lot. The junior ADU must be within the existing home’s footprint. For multifamily lots, you are allowed to have two detached ADUs and one or more JADUs, though it is always best to reach out to your local jurisdiction to be certain.

Typically, your primary ADU can be up to 1200 SF; however, some jurisdictions restrict ADUs to 800 SF. Always check with your local jurisdiction for restrictions, making sure to mention your specific property. Junior ADUs are allowed to be a maximum of 500 SF; however, all JADUs must  be located within the existing footprint of your home. A garage conversion is a perfect example of a Junior ADU or JADU.

The State is allowing a 4-foot setback off the rear and side property lines. However, there can be other restrictions on each individual site. Always check with your local jurisdiction for any restrictions placed on your site.
