What is a Granny Flat Orange County, CA?
A granny flat, also known as an accessory dwelling unit or ADU, is a secondary dwelling unit that can be rented out separately from the main residence. As the name suggests many granny flats are rented out to parents, grandparents, or mothers-in-laws as a way to create an ideal multi-generational family living environment. There are many types of granny flats, such as attached ADUs, detached ADUs, or over an existing structure ADUs.
Junior ADUs are another type of granny flat that are built within the existing square footage of an existing residence. An example of a Junior ADU is converting an attached garage into a living space with a full kitchen and its own external entrance. Part of the primary residence could also be sectioned off to create a Junior ADU. However, a Junior ADU can be no more than 500 square feet.

How to Build a Granny Flat Orange County, CA
Unfortunately, building a granny flat in Orange County, CA is not always simple. There are state laws and codes that must be followed, in addition to your local jurisdiction’s laws and codes. What you are allowed to build in one city, may very well be rejected by the city only blocks away. Because of these complicated rules and regulations, it is best to reach out to a company that specializes in building ADUs or granny flats specifically.
The first step for you or any company you hire is going to be reaching out to your local planning and building departments to determine their laws and codes relating to ADUs. As previously mentioned, ADU codes, size and height requirements, among many other technicalities, differ per city. Therefore, it’s extremely important to check to see what is and is not allowed. Once you have that information, you can approach your project with a realistic expectation of what you can build

Once you know what’s allowed to be built and the basic requirements that must be followed, you’ll then need to acquire ADU Plans. ADU plans can be drawn up by an architect or qualified draftsman and vary highly in cost and quality. In order to complete the ADU plans, an electrical engineer and often a structural engineer will also need to be hired to perform certain calculations necessary to ensure structural safety and integrity. The city may also require soils reports, grading plans, and/or drainage plans.
Completed plans will then need to be approved by the city in order for building permits to be issued. The city does charge a fee for permits, and the price varies based on several factors. Once plans are approved and permits are in hand, construction of the ADU can then begin. Usually, a general contractor handles construction of an ADU, but it’s also good to have a project manager overseeing the process. You may also want to consult with an interior designer about what type of finish materials should go in the ADU. Finish materials are things like the type of countertops, flooring, wall coverings, and fixtures.

At Superior ADUs, we do all of this for you. We handle the entire process, which includes communicating with your city, drafting and engineering ADU plans, design, construction, and project management and coordination throughout. You can either choose to build one of our ADU Models, where the plans are already complete, or you can choose to have a custom ADU designed specifically for you.
