In recent years, the popularity of auxiliary dwelling units have been growing in California. ADUs are secondary dwelling units located on the same property as a primary residence. They are sometimes referred to as granny flats, backyard cottages, or in-law units. In this blog, we'll explore what an ADU is, the benefits of building one, and the guidelines for building an ADU in California.
What is an ADU?
An ADU is a self-contained living unit that is built on the same property as a primary residence. They can be attached to the main house, built as a separate structure, or created by converting an existing structure such as a garage or basement. ADUs typically have their own entrance, kitchen, bathroom, and living space.
Benefits of Building an ADU:
Increased Housing Options: ADUs provide an additional housing option for homeowners and renters, which is especially important in areas with high housing costs and limited availability.
Additional Income: Homeowners can rent out their ADU for additional income, helping to offset their mortgage or other expenses.
Multi-Generational Living: ADUs provide an opportunity for multi-generational living, allowing elderly relatives or adult children to live close by while still maintaining privacy and independence.
Environmental Benefits: ADUs can be designed with sustainability in mind, including features such as solar panels, energy-efficient appliances, and water-saving fixtures.
Guidelines for Building an ADU in California:
California has passed laws to encourage the development of ADUs, making it easier for homeowners to build them. However, there are still guidelines that must be followed. Here are some of the key requirements:
Size Limits: The maximum size of an ADU depends on the size of the primary residence and the local zoning laws. In California, ADUs are typically limited to 1,200 square feet.
Parking: Depending on the location of the ADU, parking may be required. However, in some cases, local zoning laws may allow for a waiver of parking requirements.
Building Code Requirements: ADUs must comply with all local building codes and zoning laws, including setback requirements, height limits, and fire safety regulations.
Permitting: Homeowners must obtain permits from their local jurisdiction before building an ADU.
ADUs can provide many benefits for homeowners and renters in California. They provide additional housing options, the potential for additional income, and environmental benefits. While there are guidelines that must be followed when building an ADU, the state of California has made it easier for homeowners to take advantage of this option. If you're interested in building an ADU, it's important to work with a qualified contractor and obtain the necessary permits from your local jurisdiction.
